A foreword by the Rt Hon. Sir James Cleverly TD VR MP, Shadow Secretary of State for Housing, Communities, and Local Government

London succeeded because it combined ambition with opportunity. It is one of the world’s great cities because generations before us had the confidence to invest in its future, build for growth and create the conditions for people to succeed.

Today, that promise is under increasing strain. For too many Londoners, particularly younger people and families, finding a secure and affordable home feels further out of reach than ever before. That matters both for those individuals and for the long-term success of our capital and the prosperity of the country as a whole. A city that attracts talent from around the world must also remain a place where people can build a life, put down roots and look to the future with confidence.

This report brings renewed focus to the scale of London’s housing crisis and the consequences of failing to address it. It sets out a compelling case for how we can make better use of land, support regeneration, unlock brownfield sites and reduce the layers of red tape, regulation and complexity that have made it much harder to deliver the homes our city needs. Above all, it is a reminder that the decisions we make today will shape the opportunities available to future generations.

Successful development is about more than numbers alone. It is about creating places where people want to live, work and raise families. It is about supporting aspiration, widening opportunity and ensuring that economic growth is matched by improvements in people’s everyday lives.

Ben Hopkinson and Laurence Fredricks deserve credit for setting out a bold and ambitious vision for London’s future. At a time when the capital faces significant challenges, this report provides a detailed and thoughtful analysis of how we can build a more prosperous, dynamic and opportunity-rich city for the generations to come.

A foreword by Laila Cunningham, Reform UK’s mayoral candidate for London

Let me start by telling you the truth.

I should not be writing this foreword. You should not be reading this paper. In fact, this paper should not even exist.

A city as wealthy, dynamic and successful as London should never have had a housing crisis. Yet after decades of failure by both Labour and Conservative governments and mayors, that is exactly where we find ourselves today.

London’s population has grown dramatically, driven in large part by mass immigration, while housebuilding has failed to keep pace. The result was predictable. House prices soared, rents exploded, and an entire generation of Londoners found themselves locked out of home ownership.

Instead of addressing the issue, City Hall has made the problem worse. Housing projects are burdened with endless bureaucracy, planning delays and ideological obstacles. Housing development should be one of the most attractive investments in London. Instead, too many investors look elsewhere.

This cannot continue.

As Mayor, I will fight to Make London Affordable Again. That means increasing housing supply, reducing unnecessary red tape, encouraging investment, and ensuring that London’s housing policies put the interests of Londoners first. Social housing is a limited public resource and must serve British citizens and those who have contributed to our society.

The housing crisis was created by political decisions. It can be solved by political decisions.

I would like to thank Ben and Laurence for their work. Their analysis of London’s housing crisis provides an important contribution to the debate and will serve as valuable input as we develop the policies needed to restore affordability, opportunity and home ownership to our capital.

A foreword by Laurence Fredricks, co-author of Fixing London Housing

When I first moved to London as a recent graduate, I had no idea that I would become homeless. But last autumn, I became a sofa-surfer – one of the approximately 167,000 homeless people in the capital.

This was not a consequence of losing my job, or any financial problems. There were just not enough houses. Despite months of desperately searching for a new place to rent, I could not find any decent options. Even when properties became available, far too few were being rented at a price I could afford, even on a good wage.

When I did eventually find a place to live, it was not the end of my problems. Like many other Londoners, my rent today is roughly half of my post-tax salary, even before transport and bills. The very idea that I could ever save up to buy a home is frankly preposterous. And I am not alone. Young people of our generation who have done everything right, from getting a degree to moving to London and getting a well-paying job, are unable to build a life. The other day, one of my friends casually mentioned that he had moved 14 times in five years. Like many of our generation, he is now considering leaving the UK.

There is one obvious cause of this: there is far too little housing being built. In 2024/25, only 4,170 homes started construction in London. During that same period, the capital’s population grew by just under 100,000.

The solution is not complicated: we need more homes to be built. The current Government and Mayor were asleep at the wheel as building fell to its lowest level since World War 2 and only recently enacted temporary, ‘emergency’ reforms. Temporary reforms will not solve a long-running crisis.

For too long, it has been made harder and harder to build in the capital. A toxic combination of regulations, delays and political hesitation have constrained supply while demand has continued to grow.

There have been attempts to grapple with this reality. The last government recognised the scale of the challenge to build in London and began the work on reform. The then-Secretary of State, Michael Gove, commissioned a review into the London Plan. But this was cancelled by Labour’s Angela Rayner. Progress has since stalled, and the fundamental issues remain unresolved.

The outcome is that London cannot build, but it also cannot afford further delay.

And the opportunity is clear. As we set out in this report, London has the capacity to densify while remaining one of the most beautiful cities in the world. Matching the density of cities such as Paris or Osaka across Zones 1-3 could deliver hundreds of thousands of additional homes. And aside from giving people a place to live, it would generate significant economic reward, contributing billions to the economy.

Reversing London’s housing decline is a political, economic and generational imperative. This report sets out how the next mayor and government can, should and must do so.

Executive Summary

London is failing to build the homes it needs. In 2024/25, construction started on just 4,170 homes in the capital, even as the population grew by close to 100,000. This dramatic fall in starts means that London is facing its largest housebuilding challenge since the Second World War.

This has been caused not just by global economic forces, but by policy choices that have increased construction costs, restricted the land that can be built on, and added more regulatory hurdles to clear.

London has not built anywhere near the Government’s target of 88,000 new homes a year since the 1930s. Resolving London’s shortage by bringing the cost of housing closer to the cost of construction will require around 1.85 million additional homes, or roughly 100,000 a year over two decades.

This is achievable: cities like Tokyo and Austin already match or exceed that on a per-capita basis. But the consequences of failure are severe.

By the ONS’s definition of affordability, a household on the median London income cannot afford any property in the capital. House prices in London have risen 7.5 times faster than inflation since 1970. London’s failure to build is also raising house prices across the South East. This failure has national impacts: Public First estimates that meeting the 88,000 target would generate £14.8bn in annual GVA and over £6bn a year in additional tax receipts by 2034, enough to fund significant tax cuts.

For the Conservatives and Reform, the political logic points the same way. London is the region with the strongest local support for new building (59% in favour, 14% opposed) and inner London has relatively low centre-right support. The political cost of unlocking supply is therefore lowest precisely where the need is greatest. There is, in short, an unanswerable case for both parties to make a major London housebuilding programme central to their next manifestos.

This report sets out the case for such a programme, and a detailed prescription of how it could be delivered, along with clearly delineating which existing powers can be used and where they sit.

Chapter 1, on why London needs to build, establishes the scale of the shortage, its economic and social costs, and the case for treating London as the centre-right’s housing priority.

Chapter 2 identifies five categories of site capable of delivering the homes London needs:
 

• Three mayoral or urban development corporations, covering the most strategic areas. These are Southern Tower Hamlets between the City and Canary Wharf (potentially 300,000+ homes), the Bakerloo Line Extension corridor along the Old Kent Road (at least 40,000 homes), and the existing Old Oak and Park Royal development corporation with an expanded remit (130,000 homes). Shadow corporations should be stood up before the next election so delivery can begin from day one.

• Estate regeneration could deliver around 500,000 additional homes by roughly doubling the density of London’s low-rise post-war council estates, supported by an automatic-permission fast track for ballot-approved schemes, encouraging for-profit housing associations to build, and re-routing funding from the Social and Affordable Housing Programme.

• Strategic Industrial Land and Locally Significant Industrial Site designations within a kilometre of a Tube, rail or tram station should be removed, unlocking 2,293 hectares of well-connected land sufficient for around 250,000 homes.
   
• Use of public land should be optimised through five-year asset management pipelines, equal affordability treatment with private land, and Crown Development Orders for larger sites.
   
• Brownfield land should benefit from a strong presumption in favour of development within the London Plan, extension of full expensing to remediation and regeneration, an exemption from Biodiversity Net Gain, and higher EIA screening thresholds.

Chapter 3, on making the most of existing properties, explains how to sensitively densify and improve the housing London already has:

• To give homeowners greater choice over their properties, permitted development rights should be expanded to allow for full-size loft and rear extensions. Local authorities should create design guides for acceptable extensions within conservation areas. The Housing Secretary should also issue a statutory National Development Management Policy to create a national ‘yes unless’ route for household extensions that require a planning application, and should pass the necessary secondary legislation to implement ‘street votes’.
  
  
• The conversion of existing commercial properties into homes should be made easier through the removal of regulations that prevent conversions, stricter limits on councils creating Article 4 directions that stop easy conversions, and the introduction of a statutory National Development Management Policy that explicitly encourages conversions and bans councils from introducing onerous barriers.
  
  
• Around £18bn a year is spent subsidising people to live in London via the benefits system. This distorts the housing market and favours people who are out of work over working Londoners – at the taxpayer’s expense. We need to end absurdities like million-pound council homes and encourage more win-win transactions. The Housing Secretary should use existing powers to encourage councils to sell off expensive social housing when it becomes vacant, with the proceeds used to fund the construction of more homes. There should be a national cap on housing benefit and the Universal Credit housing component set at the median national rent for each house size for future claims. Finally, we should revive and improve the Right to Buy and expand it by including housing association properties.

Finally, Chapter 4 covers the policy and regulations choices that have constrained delivery:

• Housing targets should be set according to the gap between median house prices and basic construction costs, which would raise London’s target to around 145,000 homes a year while reducing pressure on regions where demand is weaker. The Housing Secretary should also use their powers to designate underperforming councils, rewrite their local plans of underperforming councils, and call in larger applications in such areas.
  
  
• Affordability requirements should be removed from the London Plan and replaced with a simpler unified Infrastructure Levy based on a share of development value.
   
• A series of specific rules within the London Plan – covering private outdoor space, minimum space standards, dwelling mix, affordable workplace and student accommodation, car parking, emission standards and accessibility – should be unwound.
  
  
• Nationally, second staircase requirements should be raised to 50 metres in line with France, Germany and Ireland, and Parts F, L, O and S of the Building Regulations loosened to pre-2021 baselines.
  
  
• The Building Safety Regulator, which has been one of the most significant causes of London’s housebuilding slowdown, requires structural reform – either through an alternative, insurance-based route through the system or by raising the height threshold to bring the regime into line with international practice.

London’s housing crisis is solvable. In most cases, the policy levers exist within current legislation – and the political conditions are more favourable than at any point in recent memory. What is required is a programme of action ready to begin on the first day of a centre-right mayoralty or national government taking office.

1) Why London Needs to Build

London housebuilding is facing its largest challenge since the Second World War. Despite the capital having clearly the highest demand for new homes in any region in England, it is now building the fewest homes per capita. The rest of England is building at four times the rate.^[1]

The Government has set London a housebuilding target of 88,000 homes a year.^[2] But last year, it managed to start less than 5,000.

This is not just a short-term problem – although the current situation is certainly catastrophic. London has not been close to delivering the necessary level of new homes since the 1930s. But it has worsened recently, with surging demand as London’s economic prospects improved from the 1980s onwards stymied by a lack of new supply.

The failure to build more houses in London is more than just a wobble, or the temporary consequence of the botched introduction of the Building Safety Regulator. It precedes the consequences of high interest rates and surging build costs in the wake of the pandemic. It is the product of a steady squeeze, over years, on the number of places that can be built on and the profits that can be made by doing so.

If you restrict land use, add regulation after regulation, and attempt to squeeze out every pound you can from a development – or force developers to build a large proportion of unprofitable housing as part of the development – it is no surprise that you do not get any housebuilding.

The Government, and the Mayor of London have recently agreed an emergency plan to boost housebuilding. These measures include temporary relief from the Community Infrastructure Levy (CIL) where schemes meet affordable housing requirements; a time-limited planning route for developments meeting affordable housing requirements; and the removal of guidance in the London Plan that can constrain density – including limits on the number of flats that can be built around a building core. Affordable housing requirements were also temporarily downgraded from 35% to 20% of the project’s total in recognition of viability constraints.^[3]

These are welcome steps, but they do not go far enough to get London building the homes it needs. Moreover, if these are measures meant to get more houses built, why are they temporary rather than permanent?

These emergency measures amount to fiddling around the edges, rather than making significant progress on resolving the large shortage. Based on the existing population of London, the capital needs 1.1 million more homes to get to the Western European average of homes per capita.^[4] Yet even that understates the shortage. If we build more in London, workers from across the country will want to move to make the most of the higher-paying jobs. Getting the cost of housing close to the cost of construction should be the ultimate goal, as that is when the shortage would be resolved.

Ending London’s housing shortage therefore would require roughly 1.85 million new homes.^[5] Clearly this is a large number and will not be built within a single mayoral or parliamentary term. Instead, the goal should be to build around 100,000 homes a year over the course of two decades. Globally, this level of building already happens in other major cities. The core metropolitan region of Tokyo averaged 155,000 new homes a year over two decades, the equivalent (adjusted for population) of London building at 104,000 homes a year.^[6] Austin, Texas has recently liberalised its planning system and is now building 32,000 homes a year, the per capita equivalent of London building 113,000 a year.^[7] As a result of building, both Tokyo and Austin have seen rents become more affordable.

The consequences of London’s housing shortage are brutal. The average house in London cost £5,298 in 1970.^[8] Today it costs £554,000. Had house prices risen solely with inflation, the average London home would cost just £73,590. Instead, London’s house prices have outpaced inflation by over 7.5 times.

Had other goods increased in price as much as housing in the capital, a pint of beer would cost £17. A litre of petrol would cost £8, which means filling up an average tank would cost £400. A pint of milk would be over £5 and a dozen eggs would cost £24.

House price growth has also vastly outstripped wage growth. The average weekly wage for a full-time worker in 1972 was £32.^[9] Had wages matched London house prices, the average worker would be on nearly £175,000, instead of £39,000.^[10]

This is a catastrophe not just for the capital, but for the country as a whole. Yet it is felt most keenly by those young people who are trying to carve out a future for themselves.^[11]

Housing affordability in London has collapsed
Only the richest can afford even the cheapest houses.

Chart: CPS and Onward^[12]

The Office for National Statistics (ONS) classes any house as unaffordable if it costs more than five times a household’s income. As the chart above shows, this means that only the very cheapest houses are affordable – and then only to the very richest households. The average house is not affordable for anyone, even the top 10% of earners. By the ONS’s definition, a London household with a median income cannot afford any property, not even the cheapest 10%. As a result, the only people getting on the housing ladder are those with inherited wealth.

London’s high house prices are a disaster for aspiration and family formation. Given the cost of buying a home – especially a home suitable for families – it is of little surprise that London has the lowest fertility rate of the English regions.^[13] Indeed, in 2022, the number of babies born in London was 20% down on a decade before.

London’s housing shortage has a knock-on effect on the economy

London is the UK’s economic engine, generating 22.3% of the country’s total economic output.^[14] On an output per hour basis, the average Londoner is significantly more productive than someone living in the rest of the UK: GDP per person in London is £69,077 compared with £39,043 across the country.^[15]

London’s economic success benefits the rest of the UK. In 2022/23, London generated £216.4bn in tax receipts, but government spending in the capital was only £172.8bn. That is a surplus of £43.6bn, or nearly £5,000 per Londoner, to provide public services to the rest of the country.^[16] This means that the entire country does well when London is allowed to grow.

However, this growth is being artificially constrained. The number of jobs in London has grown far more quickly than the number of homes. Today, there are 61% more jobs in London than there were in 1996, but only 27% more houses. If London’s housing stock could keep up, the economy would grow much faster.

To see how extensive this shortage is, consider the following. The median London worker earns 17% more than the median UK worker. With those higher wages, people ought to be clamouring to move to the capital. However, once the rent of a one-bed flat is taken into account, the median London worker is actually 3% worse off than the median UK worker.^[17]

To put that another way, many people could earn significantly more in London but are better off staying in a worse-paying and less productive job because of unaffordable housing.

And of course, what you get for that rental money is worse value than the rest of the country. For the average cost of renting a one-bed flat in London, a couple could rent a three-bed house in any other UK region. The average home in London is 10m² smaller than the English average, despite costing 91%, or £264,000, more.^[18]

The scale of London’s contribution to the national economy means that increasing its economic capacity delivers significant national benefits. Analysis by Public First has estimated that achieving the Government’s target of 88,000 homes per year in the capital could generate £14.8bn in annual GVA, or £118.7bn by the end of the next Parliament, boosting London’s GDP by 2.4%.^[19] That includes potential benefits to the Exchequer of more than £6bn annually by 2034, including £4.1bn generated through the effects of more workers being closer to greater job opportunities in the capital.^[20]

By unshackling the housing market in London, the government can raise greater tax revenues and use that extra cash to pay for public services or reduce or even axe unpopular taxes.

For example, the fiscal benefits outlined above would be enough for the government to halve the rate of inheritance tax for £4bn and remove inheritance taxes on family farms too.^[21] Alternatively, the proceeds from enabling more housebuilding in London could fund 1p off of National Insurance Contributions or restore the personal income tax allowance for everyone, which would remove the pernicious 62% marginal tax rates between £100k and £125k.^[22]

Whatever the next Chancellor chooses, allowing more housebuilding in London will enable tax cuts or public service improvements.

The economic success of London is underpinned by the capital’s housing market and density

London’s economy is driven by agglomeration, where density facilitates interactions between people, spurring social and economic activity. London is by far the densest of the UK’s cities, with an urban core approximately twice as dense as the average British city.^[23] And this concentration delivers major economic returns: roughly 13% of the UK’s population is in London, but the city contributes 22.3% of the UK’s GDP.

Yet compared to many of its rivals, London is not actually that dense at all. Relative to Paris, London’s urban core is missing around 700,000 homes and almost 950,000 compared to Osaka in Japan.^[24] Just matching Parisian density in Zones 1-3 would add 500,000 more homes.^[25]

The underutilisation of land is visible across the capital. Take Tower Hamlets, the UK’s densest and one of the most economically productive boroughs.^[26] Despite having the highest GVA per hour worked in the country and supporting more than 160,000 jobs, densities within the borough vary dramatically: you can go from the skyscrapers of Canary Wharf to terraced housing in under 500m.^{[27] [28]}

In short, fixing London’s housing crisis is an economic necessity for Britain. But it is also a political necessity for the centre-right.

London’s housing failure has spread the housing crisis across the South-East

People would like to live in London for all sorts of reasons. But many of them cannot afford it and are forced further out. That means house prices rise in the towns and cities that surround London, like Guildford, Brighton, and Reading. That in turn pushes people further out and prices up in surrounding towns and villages and puts added pressure on the green belt.^[29]

The construction of new houses has historically been a complicated political area for the centre-right. While home ownership is foundational to building communities and giving the young a stake in society, new construction is less popular among right-leaning voters than left-leaning voters. Recent Ipsos polling shows that while 63% of 2024 Labour voters support building more in their local area, only 39% of Conservative and 27% of Reform feel the same.^[30] That’s compared to 33% of Conservative voters and 46% of Reform voters who oppose building more homes near them.

London, especially central London, is both the UK region with the highest support for new construction in the local area (59% in favour versus 14% against) and also a region with relatively low centre-right support. At the 2024 election, Reform did not win a single constituency in London. The Conservatives did not win a constituency that did not border the Home Counties. Chingford and Woodford Green was the closest to central London, and that’s nearly ten miles from Charing Cross.

In short, building more homes in London is popular with existing residents, less likely to anger existing centre-right voters – and dilutes pressures in the rural and suburban seats that centre-right parties traditionally hold.

The two following charts, from the 2024 election, show that the further a constituency is from central London, the more votes both Reform and the Conservatives tend to win.

To put specific numbers on that: within Greater London, there were 46 constituencies where the Conservatives received fewer than 10,000 votes in 2024, compared to 29 where they received more than 10,000. For Reform the numbers were even starker. There were only two constituencies where they won more than 10,000 votes (Hornchurch and Upminster and Old Bexley and Sidcup), and 73 where they received fewer than 10,000 votes.

This trend mostly continued with the 2026 local elections. The Conservatives and Reform achieved their best results in outer London boroughs while the Greens and Labour were more successful in inner London, except Westminster and Kensington and Chelsea.

Past attempts to reform the planning system and boost housebuilding levels have failed, in large part, due to political backlashes. Given the necessity of addressing the housing shortage, it is vital that any future government on the right prioritises unlocking development in areas where local opposition is weak and where the political cost of local opposition is the lowest. All of those factors point to London, where the housing shortage is most dire, local residents are most supportive of new building, and the centre-right faces the lightest political headwinds for more building. Building in London also reduces the pressure to build in the green belt, which is unpopular with centre-right voters.^[31]

In short, there is a pretty unanswerable case that both the Tories and Reform should prioritise a major housebuilding programme in London. But how many homes, and where?

2) Where to build

Perhaps the first question that comes to mind when thinking about increasing housebuilding in London is, where? That’s especially pertinent given the approximately 1.85 million homes London needs. Isn’t the capital full, with no land to build on?

There is, of course, some truth to this; London is by far the most built-up region in the UK.^[32]

But London is also full of opportunities to make better use of existing land. Existing land use policies have artificially restricted where new homes can be built. Social housing built in the 1950s through 1970s is both low density and in need of major regenerative work. For more strategic sites, co-ordination challenges and councils with limited incentives to drive forward change have stopped neighbourhood-scale new developments. Public land and other brownfield sites also provide significant opportunities but have been underdelivering.

We propose five different types of locations where London can and must build the homes it needs:

1. Mayoral or Urban Development Corporations should be established for the most important strategic sites.
   1. The first of these should cover the area between the City of London and Canary Wharf, which has the potential to be a global economic powerhouse with millions of square feet of office space and at least 300,000 new homes.
   2. The second would improve the effectiveness of the existing Old Oak and Park Royal Development Corporation, which is hobbled by restrictions around land use imposed by the current Mayor. This area is surrounded by Tube and rail stations, including the future HS2 megahub, and has the potential for 130,000 new homes in addition to retail and office spaces.
   3. Finally, a third corporation should cover the area along the Old Kent Road served by the planned Bakerloo line extension, which has the potential for at least 40,000 homes.
2. We should focus on renovating existing council estates that are built at low densities. By expanding the successful policy of estate regeneration with new planning and financing powers, the uplift in density at existing estates could deliver 500,000 additional new homes.
3. We should remove Strategic Industrial Location status from areas within a kilometre of an existing Tube, rail or tram station. This could provide the space for 250,000 well-connected homes.
4. Public land should be optimised for housing by requiring public bodies to identify developable sites and create clear five-year delivery plans, with Crown Development Orders used for larger sites.
5. A clear, strong presumption in favour of brownfield development should be introduced within the London Plan to resolve policy conflicts, combined with full expensing for brownfield land regeneration projects, and exemptions from biodiversity net gain. Brownfield reform is the foundation that makes the strategic sites set out above deliverable, and would additionally unlock substantial dispersed capacity on smaller brownfield sites across London.

Of course, identifying the land on which to build is only the first step and will not solve London’s housing shortage alone. In future chapters, we will discuss making the most of existing properties alongside new developments, high affordability requirements that destroy viability, the regulations and policies that need to be changed, and incentivising local councils to allow more construction.

But for now, we will focus on the parts of the city where the opportunities for densification and regeneration are greatest.

Special/Mayoral Development Orders and Development Corporations

Many of the recommendations in this report are about making the housing market work better. But to make the most of the biggest opportunities in London, government involvement is needed – if only to clear away the obstacles that are blocking development.

Development corporations have already proven themselves in the capital with the transformation of dilapidated docklands into Canary Wharf, one of the world’s great financial centres. Likewise, the Olympic Games led to the transformation of areas near Stratford from rundown industrial land into thriving new neighbourhoods.

Development corporations can be the organising force behind major regeneration projects. They can act as the local planning authority, which means creating both a local plan and approving planning applications, but they do not face the same financial pressures that local authorities are currently experiencing. They also have the power to resolve potentially thorny problems around land assembly, infrastructure provision, and development phasing.

Both the Secretary of State and the Mayor of London have the power to create development corporations. The London Docklands Development Corporation that drove the creation of Canary Wharf and the revitalisation of much of the East End was created by the Thatcher government. The London Legacy Development Corporation that cemented the success of the Olympic Games in regenerating Stratford was created by Boris Johnson when he was Mayor of London.

There are areas of central London where we can recreate this success. The three best options are the area between the City and Canary Wharf, the Old Oak Common and Park Royal industrial area, and along the Old Kent Road where the Bakerloo line extension is planned to run.

Old Oak Common and Park Royal already has a development corporation, but this is severely restricted by the land use policies that Sadiq Khan has applied. These policies and the resultant local plan can be changed by a future Mayor or Housing Secretary.

While development corporations are already powerful organisations, there is potential to further increase their powers to deliver at the scale needed. Any compulsory purchases at the beginning of construction will need to be funded from capital markets. This can all be self-funding given the large increase in land values if the development corporations are given the ability to borrow and are exempt from the fiscal rules.^[33]

One of the most important challenges with this solution is the time it takes to deliver. All three of our suggested projects are major undertakings that will outlast a single mayoral or parliamentary term. To have the best chance of success, work must begin immediately after an election. In the run-up to an election, whether it be mayoral or general, parties on the centre-right should establish a shadow development corporation for each of these areas. The shadow development corporation could outline the goals of the regeneration and begin creating the plans for redevelopment so that on the first day of the next Mayor or Parliament’s term, the development corporation could be created quickly.

To further speed up the planning process, a special development order or a mayoral development order could be applied to the plans that the development corporation draws up. This would quickly grant planning permission for developments that match the plan. Such a combination was used successfully in the 1980s to deliver a large-scale regeneration project around Cardiff Bay.

Southern Tower Hamlets

London contains two of the centres of global finance, the City and Canary Wharf. The Square Mile alone has a GDP over £110bn, which rivals entire countries like Kenya or Croatia.^[34] These are two of the most economically productive areas anywhere in the world. This level of economic activity is visible from London’s skyline too: one cluster of skyscrapers in the City and another in Canary Wharf. Yet there is a three-mile gulf between them.

In Tower Hamlets the skyscrapers of Canary Wharf are 300m away from two-storey terraced houses. More than 50% of the homes in this output area are socially rented

The drop-off is sudden. Some of the tallest buildings in the country are less than 300m away from two-storey terraced council homes. Instead of being full of mixed-use residential and office buildings, the area is mostly low- or mid-rise council housing. In some neighbourhoods, 55% of homes are socially rented.^[35] The existing housing stock is mostly from the 1950s and 60s and is increasingly in poor condition. This land has the potential to cement London’s status as one of the most important cities for the global economy, yet it is currently being let out at far below what it is worth.

An ambitious government has the potential to change this.

The areas of Poplar, Shadwell, and Limehouse should all fall under a new development corporation with the explicit mandate of maximising the economic productivity of this high-potential area. Mixed-use developments of new homes, offices, lab spaces and commercial buildings should be targeted. This area is prime for a new generation of high-rise buildings, which will complete London’s skyline and become not just an economic hub for London, but potentially for the country and world.

These Tower Hamlets sites are both within easy walking distance of the most economically productive area in the country

Given that existing land ownership is fragmented, which would make coherent redevelopment challenging, the next Government should introduce the primary legislation enabling land readjustment. This mechanism, used successfully in Japan, Spain and other countries, allows various owners of a fragmented area of land to pool that land so that it can be developed as one.^[36] The original owners are then compensated with a new parcel of land that has significantly appreciated in value given the redevelopment. The development corporation could function as the adjudicating body of the necessary land readjustment.

Existing residents should be given a right to return to newer, nicer properties or an option to cash out. This can be funded by the significant uplift in land values that the development corporation will create.

For such a large-scale redevelopment, new transport links will need to be developed. Already the Elizabeth line and DLR provide good connectivity, but more can be done. A forthcoming report by a group of transport policy thinkers and planners will lay out the possibilities around Crossrailing the line into Fenchurch St, which would provide rapid connections from Southern Tower Hamlets across central London.^[37] The report will detail the feasibility of self-funding this project solely through land value capture. This project would also allow the conversion of the existing railway arches corridor from Fenchurch St to West Ham to a DLR service with higher frequencies than the current national rail service.

This is a large and complex undertaking and will take time. Yet it also has the potential to reshape London’s economic and cultural geography for centuries to come. Because of the time involved, the broad strategic goals of the development corporation should be set in opposition and the primary legislation for land readjustment drafted, so that the development corporation can be created on the first day of a new government.

Old Oak Common and Park Royal

The Old Oak Common and Park Royal area provides the best opportunity within London to create a new neighbourhood.

When Old Oak Common station opens, this area in West London will have a credible claim to being the best-connected place in the entire country. HS2 trains will speed towards the Midlands, the North West, and Scotland. The Great Western Main Line will provide easy access to the West Country, South Wales and Oxford. The Elizabeth line station will mean Heathrow is 20 minutes away and central London a mere 10. That’s in addition to the 11 existing Underground stations on the Piccadilly, Central, Bakerloo and Overground lines that surround the site. If the West London Orbital goes ahead, there will be a third Overground line to connect the area to more parts of West and North London.

For such a well-connected location, the urban environment is distinctly underwhelming. The Park Royal area is made up of street after street of single storey warehouses. There are a surprisingly large number of Lebanese bakeries too, and a McVitie’s biscuit factory. The only reason that industry has continued to cluster here is that the land is legally protected by the London Plan from being redeveloped into a mixed-use neighbourhood. In effect, that results in large subsidies for the existing industrial uses.

A collection of scenes from Park Royal. This is all legally protected land that cannot be redeveloped into homes despite being surrounded by Tube, rail, Overground stations and soon HS2

Take Channel Gate, an industrial site between Willesden Junction and the future Old Oak Common station. Channel Gate is currently partially being used to construct the HS2 station, with the rest of the site being open storage land and a bus depot. In 2021, the nine-hectare site was valued at £92.8m given its existing uses.^[38] But if it were regenerated into 3,100 homes, the land value could go as high as £312.5m. That means because of the strategic industrial location designation, there is an implicit subsidy of around £220m for just this one site, or around £25m per hectare.

Within Park Royal there are 325 hectares of SIL that are within a kilometre of a station. By applying the Channel Gate rate of implicit subsidy, that’s £8bn of land value that could be unlocked if we liberalised planning in just this one small area of West London. At Parisian densities of 400 dwellings a hectare, this well-connected land provides enough space for 130,000 homes, plus at least 300,000 square metres of retail and office spaces.

Map showing the opportunity in Park Royal. The existing development corporation’s boundary is shown, alongside Strategic Industrial Locations (green), Locally Significant Industrial Sites (red), and a 1km radius around stations (12-minute walk).

Old Oak and Park Royal will also be the fastest area to deliver because it already has a development corporation set up. The existing development corporation is re-developing parts of the site, including a 28-hectare site near the HS2 station, however this is less than a tenth of the opportunity that this area brings.^[39] The challenge is that the Old Oak Park Royal Development Corporation does not have the ability to overturn SIL designation and has been very conservative in suggesting removal of SIL status. The corporation’s Local Plan commits

specifically to no net loss of industrial floorspace within the local area.

That is simply too limiting to take advantage of potentially the best opportunity in a generation to build a completely new area of London. The existing industrial land is absolutely not the best use of this well-connected Zone 2 site.

The arguments for banning new homes on SIL do not add up. While it is true that the workplaces for tens of thousands of Londoners are in a SIL, it does not follow that their jobs would disappear if the site was redeveloped. Some industrial users may move out of London to cheaper parts of the UK that are better connected to the strategic road network, while others may find ways of co-locating. The Mayor and Housing Secretary should actively encourage new industrial sites to come forward in and around London that are well-connected to the road network. Additionally, there would be opportunities for new businesses, such as life science labs or start-up offices, to move into mixed-use communities.

The Government should plan for the reprovision of industrial land where possible, especially by allocating new industrial sites in and around London that are well-connected to the road network. But it should not arbitrarily insist that it has to remain in the same location so close to central London.

Another argument is that having warehouses in central London means that delivery drivers have to drive fewer miles, helping traffic congestion. This is true, but it misses a wider truth. The environmental benefit of the shorter drive is vastly outweighed by the opportunity of giving over a hundred thousand families the chance to own a new home. Additionally, redevelopment of the area will involve people moving from outer London, closer to the centre where there is less need for them to drive or own a car, reducing congestion on the roads.

The Mayor of London should expand the remit of the existing Old Oak and Park Royal Development Corporation to include the Strategic Industrial Locations and amend the London Plan to remove the Strategic Industrial Location designation.

Alternatively, the Housing Secretary could resolve the issue of the existing industrial land through a two-part process. First, the Housing Secretary would need to remove the Strategic Industrial Location designation from the London Plan, which could be done through sections 340 and 341 of the Greater London Authority Act 1999. That would direct the Mayor to make the necessary changes to the London Plan. Then, the Housing Secretary should use their powers under s15GA of the Planning and Compulsory Purchase Act 2004 to revise the local plan of the Old Oak and Park Royal Development Corporation so that it no longer treats the relevant land as SIL and instead allocates it for the intended regeneration-led use.

Either the Mayor or the Housing Secretary can resolve the issue of uneconomic warehouses subsidised to be in the best-connected area in the country. Having made the necessary changes to the local plan, the existing development corporation will then be able to build London’s newest neighbourhood surrounded by the existing and new HS2, National Rail, Elizabeth line, Underground, and Overground stations.

Old Kent Road and the Bakerloo Line Extension

Most Brits will know the Old Kent Road because it is the cheapest property on the Monopoly board. There are strong reasons for this. The current road is traffic-clogged and subject to a hodgepodge mix of new development, worn-out estates, big-box retail and dilapidated industrial sites. It is also the Monopoly board street furthest from a Tube stop.

The Bakerloo line extension (BLE) will change this. Proposals to extend the Bakerloo line from its Zone 1 terminus have been mooted since before the line even opened in 1906. The current plans for an extension along the Old Kent Road trace their origin back to 2006. Yet despite over a century of talk, we are no closer to delivery. Opening the BLE is an opportunity to connect the largest public transport desert in central London and build tens of thousands of homes at the same time.

Tying a transport project to a regeneration scheme has worked well in London before. Before the Northern line extension, Battersea Power Station sat empty. Though physically close to London’s centre, poor transport links made redevelopment an unviable proposition. Two new stations and a link to one of London’s most used Tube line changed that, allowing for 20,000 new homes, a new UK headquarters for Apple, and a vibrant tourist attraction. The construction around the power station generated enough business-rate growth and developer contributions to repay the borrowing used to build the Underground extension.

The BLE exists in similar circumstances: close to central London but poorly connected and rundown. The Old Kent Road is dying and the new cannot be born (until the BLE is delivered); in this interregnum a great variety of morbid symptoms have appeared. The area is loud and congested, with a constant churn of buses and delivery vans. There’s a scattered mix of large retailers with massive car parks, warehouses and tired-looking parades of takeaways and betting shops. Patches of new development sit awkwardly beside neglected plots and ageing estates.

Scenes along the Old Kent Road. The first two surface car parks are the planned sites of future Bakerloo line stations

The Old Kent Road is also shockingly low-density, partially as a result of relying on buses rather than an Underground line. Despite being just 2.5 miles from the centre of London, the areas around the future stations average 46-57 homes per hectare, about the same as terraced housing.

Sadiq Khan has claimed that 20,000 homes could be built along the proposed Tube line. However, that is hugely unambitious. Getting the level of density around the stations up to 100 homes per hectare, about the same density as Greenwich, would unlock double the number of homes that the Mayor is planning. Even more homes could be unlocked with a local plan aimed at reaching Parisian densities of closer to 400 homes per hectare.

Within the area near the station there is significant opportunity for a development corporation to deliver these homes. There are 47 hectares of Strategic Industrial Land (SIL) and 17 hectares of Locally Significant Industrial Sites (LSIS) within walking distance of the proposed stations. If built at 400 dwellings per hectare, similar to Parisian densities, this land would host over 25,000 homes.

Likewise, there are 43 council estates within walking distance of the proposed stations. These were built at a time when London was depopulating and the primary concern was overcrowding. That means that despite some of these sites containing a tower block, they were actually built at relatively modest densities: 110 dwellings per hectare average in Southwark and 77 dwellings per hectare in Lewisham. Estate regeneration, discussed below, could net a further 15,500 additional homes by replacing the existing, outdated estates with higher-quality new homes.

A development corporation is the best vehicle for regenerating the area along the Old Kent Road. At the same time, the corporation could focus on raising money to deliver the extension through targeted land value capture. Currently, significant parts of land value capture go towards the provision of subsidised housing through affordability percentages and section 106 commitments. Instead, the corporation should be targeted specifically to maximise the amount of funding to help deliver the BLE. That means choosing contributions towards infrastructure over subsidised housing and encouraging developments that maximise land value. One of the reasons why the extension has yet to be delivered is squabbling over who is going to fund it. The development corporation model is the answer here.

Estate Regeneration

The Aberfeldy estate was built on bomb-damaged land near London’s docks. It used to be

poorly connected and economically isolated. However, with the arrival of the DLR and Jubilee line and the regeneration of the Docklands, the estate now has easy access to the City and the West End and is within walking distance of a global hub of finance at Canary Wharf. Yet the terraces and flats have fallen into disrepair and are built at a low density, meaning that this superb location could be redeveloped to benefit more working families.

A plan to regenerate the existing 330 council homes into 1,582 homes had overwhelming

support from residents. In a ballot, 93% voted in favour with a turnout of 91% because they

would receive newer, larger properties.^[40] These replacement social homes for current tenants would be paid for by selling most of the other new homes. The only hitch to this plan was that despite complying with the local plan, Tower Hamlets’ Planning Committee unanimously voted to reject the scheme on spurious grounds, including that local people would be ‘pushed out’ and that the buildings would be too tall.

While this project was ultimately called in and approved by the Mayor, the planning difficulties added two and a half years to the project’s timeline.

Aberfeldy is just one example of a much larger problem. Most council estates in London are

built at low densities while taking up prime real estate. Britain Remade suggests that the average council estate in London has approximately 70 dwellings per hectare, about three times less dense than some of London’s most beloved neighbourhoods like Maida Vale or Marylebone.^[41]

If existing London estates were roughly doubled in density to between 126 and 146 dwellings per hectare, more than 500,000 new homes could be delivered. So great is London’s housing shortage, and the lack of density of existing estates, that large-scale estate regenerations could produce an estimated surplus of more than £80bn.^[42] This could be spent on infrastructure upgrades, rewarding residents, or cutting council tax.

Estate regenerations are a rare example of housing policy where everyone wins, including existing residents, neighbours, and new residents. When estate regenerations do happen, they’re immensely popular with existing residents. Since Sadiq Khan made ballots mandatory for estate regenerations, there have been 41 successful ballots, compared to just two unsuccessful ballots. One of those two projects was then updated according to residents’ preferences and subsequently won their support.

Existing residents are so supportive because they get to move from existing, run-down flats into newer flats in an improved local area. Existing estates are often now in unacceptably poor condition; more than half do not meet new minimum energy efficiency standards and 54% lack any insulation. Of the 10 worst UK local authorities for damp and mould complaints, eight are in London.^[43]

Local people who live near the estate also benefit from renewal. The urban fabric in their area is improved by removing the eyesores of 1960s design and better integrating the estate into existing streets. Concerns over crime and antisocial behaviour is alleviated, as the renewed estate can be designed with CCTV, street lighting, and modern security systems. Plus, estates will no longer be concentrated pockets of destitution, but liveable, mixed-tenure communities.

Finally, more homes for private sale or rent means more people can live in the capital with easy access to well-paying jobs, boosting the economy.

To encourage more estate regeneration projects to happen quickly, the Government should introduce an estate regeneration fast track. If a majority of residents vote for a plan to densify their estate, they should get automatic planning permission, subject to confirmation from the Planning Inspectorate. This could use the primary legislation laid out in Section 106 of the Levelling Up and Regeneration Act 2023. In the interim, the Mayor of London or the Housing Secretary could commit to calling-in and approving every estate regeneration that passes a ballot.

Besides planning, one of the main reasons that estate regenerations do not go ahead is the financing challenge and lack of an incentive to deliver projects for cash-strapped local authorities or non-profit registered providers. That means councils tend to only have the capacity and resources to advance one or two projects at a time.

The solution to this financing challenge is boosting the ability of for-profit registered providers to deliver estate regeneration projects. Already, local authority estate residents have the power to request a transfer of their estate from the local council to a housing association. This power should be expanded through primary legislation to enable the transfer of an estate from a housing association to another housing association if the residents vote for it, subject to reasonable compensation to the original housing association.

To further ease the financing of estate regenerations, the Mayor should make estate regeneration projects the priority recipients of the £11.7bn Social and Affordable Housing Programme. Given that estate regeneration projects help to drastically improve the stock of existing social properties, the programme’s current focus on net additionality should be removed.

Alternatively, the Housing Secretary could add stipulations to future affordable housing programmes to encourage more money being spent on unlocking these projects. Delivering more homes is the most important way to drive affordability in the capital, which estate regenerations deliver while also greatly modernising the existing social rent stock in London.

Finally, the Social Housing Regulator should amend its Governance and Financial Viability Standard to allow for-profit registered providers to make more than 5% of their turnover from non-social housing activity. This would allow for-profit registered providers to generate revenue from selling a portion of the new homes built within an estate regeneration scheme. In turn the sale of these homes, if built in high enough density, can fund the wider project.

The Packington Estate, before and after regeneration

By getting the incentives right, we can encourage these registered providers to identify the estates that have the best opportunity to be renewed. In turn, they can make a compelling offer to existing residents, who will benefit from the value uplift that the regeneration provides. They also have a strong incentive to vote for more homes as the uplift funds larger homes for existing residents and nicer green spaces. If the plans pass a ballot, the sponsors should be allowed to get on with building.

Strategic Industrial Land

London’s industry flourished in the 18th century along its rivers and in the 19th century along its railways. Yet these historical patterns of industry have been frozen in place by our planning system. The River Wandle, which flows from Carshalton and Croydon to the Thames at Wandsworth, used to have 68 mills along its length, which manufactured textiles, paper and tobacco. The mills are long gone, but a large number of single-storey warehouses have taken their place.

Likewise, large industrial sites have grown up in West London, along the Grand Union Canal and sandwiched between the Great Western Main Line and the West Coast Main Line. East London has significant industrial land along the River Thames and North London has industrial land along the River Lee Navigation and West Anglia Main Line.

All of these sites are located where they are because of industrial geographies of the past, not the present day. Yet, the warehouses are legally protected against redevelopment by the London Plan’s Strategic Industrial Location (SIL) policy and by local councils designating Locally Significant Industrial Sites (LSIS). But the industry of today clearly does not need to be built around rivers, railways, or the tram stops that have been built near the Wandle. It needs to be near the strategic road network.

All stations in London that have either SIL (green) or LSIS (red) land within a kilometre (12-minute walk)

A designation as SIL or LSIS de facto bans the building of new homes. It also implicitly subsidises existing businesses at the cost of Londoners who struggle to find a place to live. Land in London with permission for homes is worth seven times more than the same hectare used for industrial uses.^[44] By continuing to ban new homes on existing industrial land, we are taking away the pressure and ability to regenerate these areas into new mixed-use communities.

This point is worth stressing, because of the sheer amount of land that is protected by the Mayor’s SIL policy and local councils’ LSIS designations. In total, there are 3,519 hectares of SIL and 1,098 hectares of LSIS across Greater London.^[45] That’s the same size as the boroughs of Kensington and Chelsea, Islington, and Tower Hamlets combined.

Left: This street is a three-minute walk from the Battersea Power Station Tube stop. The buildings on the left, not on SIL land, contain 853 student rooms and 44,000 sq ft of office space, while the building on the right is legally protected against redevelopment because of its SIL status. Right: The same buildings from a different angle

Partially as a result of industry historically concentrating near railways, a lot of this land is close to Tube, train and tram stops. Within a kilometre of existing stations, or about a 12-minute walk, there are 2,293 hectares of SIL and 800 hectares of LSIS, which is mostly made up of single-storey warehouses. Taken together, that’s an area 22 times the size of Hyde Park. If built at a gentle density, that land would be enough for 250,000 well-connected homes.^[46]

The amount of implicit subsidy here is equally massive. Given that land with permission for homes in London is worth seven times more than the same hectare used for industrial uses, the expected total subsidy of the 3,093 hectares of well-connected land that is off-limits for housing is upwards of £96bn. That £96bn is paid by Londoners in higher rents and house prices than if the land use was left up to the market.

Maps showing specific clustering of SIL (red) and LSIS (green) land within a kilometre (12-minute walk) of a station. In order, North, East, South and West London

The London Plan should be updated to remove SIL designation that is within walking distance of Tube, rail or tram stations. That could either be done by the Mayor of London or done on a direction from the Housing Secretary through Sections 340/341 of the Greater London Authority Act. While such a policy would unlock housing across London, there are particular benefits with the area around Park Royal within West London, which deserves special treatment as described above.

The same should be done in local plans with LSIS designations. The Housing Secretary should issue a statutory National Development Management Policy that overrides LSIS designations where the site is located within walking distance of a station alongside targeted changes to local plans using their powers under Section 15GA of the Planning and Compulsory Purchase Act 2004.

Under the current London Plan, housing built on former industrial land is expected to deliver 50% affordable homes, 15% higher than normal. Given the complex remediation work that has to be done to transform a site from an industrial use to one suitable for housing, this figure harms viability and actively stops new homes from coming forward. It also stops win-win redevelopments that increase the density of industrial space while unlocking land for homes. The London Plan should be amended to remove higher affordability requirements for industrial land.

These changes in policy do not mean that all of this land will or should be redeveloped. It simply means that these sites will no longer be barred from value-maximising redevelopment. Instead of City Hall determining the best land use for the existing warehouses and sheds, we should empower the owners of these sites to determine what is best. Given the high cost of housing in London, that will often mean new homes.

It is important to stress here that redevelopment does not have to mean a loss of industrial land. Where possible, either the London Mayor or the Secretary of State should proactively identify sites that are better connected to the strategic road network. Land near motorway junctions is ideal and better suited for modern industry than city centre sites. This land should then be redeveloped to house some of the displaced industry from the removal of SIL and LSIS designations.

Finally, to ensure that the sites are not redeveloped in a piecemeal manner – with individual warehouses turned into high-rise developments while other parts of the area maintain their industrial nature – a policy of land readjustment should be used. As mentioned above, this will replace the fragmented ownership model with a better-planned redevelopment, with each of the existing landowners compensated with a more valuable plot at the end.

Public Land

Publicly owned land – land owned, managed or held in trust by the state – typically houses key infrastructure and public buildings including, among others, schools, rail assets, and Tube stations. TfL alone has 2,250 hectares of public land in London.^[47] This land is rarely vacant, but is often relatively low-density, providing an opportunity to develop unused land and build above existing assets to deliver more housing.

The potential of public land in London is significant

The opportunity to deliver housing on publicly owned land that is not reserved for public parks or key infrastructure is substantial. More than a quarter of London’s land is publicly owned and approximately 7,300 hectares of this is potentially developable, spread over 20,000 sites.^[48] Of course, much of this land will be in use, and some will overlap with social housing estates that should be regenerated. But a number of sites could come forward for development through changing land use or site intensification. At average densities, hundreds of thousands of homes could be built on these sites.^[49]

Much of this land is located in central and inner London boroughs.^[50] The greatest opportunities to deliver more housing supply on publicly owned land are concentrated in Tower Hamlets and Southwark due to the presence of sites and the average densities surrounding them.^[51]

Under-developed public land is bad value for taxpayers

At present, taxpayers fund the management and maintenance of public land that remains economically underutilised and could be used for residential development. At the same time, London boroughs spend their taxes on attempting to mitigate the consequences of housing shortages, including an estimated £5m per night on temporary accommodation.^[52] Yet the same boroughs where development opportunities on public land are most abundant face the greatest housing pressures. In 2024, approximately 69,000 households in London were living in temporary accommodation – including 2.8% of households within Southwark, and 2.1% of households within Tower Hamlets.^[53]

Sadly, however, housing delivery on public land is consistently weak. Places for London, TFL’s property arm, has identified capacity on its estate for 20,000 homes.^[54] It has committed to start on all of these by 2031.^[55] But the track record of housing being built on these sites casts doubt on whether this will be achieved. In 2015, TFL released land for 10,000 homes across London,^[56] but just five years later it admitted that it could not achieve this target, having only started work on 1,500 homes.^[57][58]

This problem is not unique to TfL land: it applies to public land across the capital. The Royal Albert Dock in East London is a barren concrete patch, with overgrown shrubs. Owned by the Greater London Authority, it has the capacity for up to 2,000 homes as part of a broader mixed-use regeneration scheme that could deliver 36,000 homes across the Royal Docks as a whole. It is located in an area already well connected by road, rail and air.^[59]

Map showing the current development opportunity at Royal Albert Dock, East London

But despite these advantages, the site has failed to progress since the first phase of development was completed in 2019. Citing financial difficulty, the initial delivery partner was terminated in 2022 after failing to progress the site into the next phases of development.^[60] The site has been promoted as a development opportunity since July 2025 and has yet to formally procure a master developer.

This highlights a broader issue: even where land is available and well-located, delivery barriers persist that can significantly delay housing supply and deter investment in areas of significant opportunity.

Building on public land in London is hard because of affordable housing requirements which are dependent on public subsidy

Under the London Plan, public land schemes must meet a 50% affordable housing threshold to qualify for the fast-track route through planning.^[61] This is a 15% greater affordable housing requirement than on private land in London. Despite this more onerous requirement, public land is no more viable than private land, facing the same macroeconomic environment, and governed by the same planning framework.

The current rationale for this extra requirement on public land – apart from the fact that the state already owns the land, and the air rights above it – is that such developments are an opportunity to provide essential workers with homes close to their places of work.^[62]

However, in making development less viable, these extra requirements lead to fewer homes being built. Policymakers who justify these extra requirements are failing to consider how a greater supply of homes, subsidised or not, would lead to lower house prices and rents for all workers, including essential ones, if this land was viable for development.

Affordable housing requirements mean that developers who are willing and able to deliver housing on public land are dependent on public subsidy to do so. Indeed, even if the state were to deliver its land at below market rate for the development of more homes, it would not resolve the difficulty of meeting affordable housing requirements. Even with zero land costs, meeting these requirements would require substantial state subsidy.^[63] This is wasteful.

At Silvertown Quays, a 60-acre publicly owned site expected to deliver 6,500 homes, an £80 million subsidy from the Affordable Homes Programme will be required to support the affordable housing offer.^[64] This is despite the site taking nearly two decades to progress, with delays driven by remediation and infrastructure costs, and despite having developers willing to deliver much needed homes on the site.

As an unnecessary additional pressure inhibiting public land development, public land should be treated the same as private land for required affordability percentages. The merits of the additional housing supply alone make the economic case for doing so, while aiding London to deliver its annual housing targets.

Many public land sites are small, which carry their own challenges

Small publicly owned sites dominate the development pipeline. Of the 20,000 potentially developable sites identified, only ~1,300 are over 20 acres.^[65] So despite their scale, smaller sites remain important areas for housing delivery.

Many of these are able to benefit from an intensification of land use. Educational facilities across London’s municipal land, for example, tend to have surplus or underutilised brownfield, with ample connectivity and infrastructure.^[66] This is incredibly pertinent in the capital, where families being priced out by housing shortages have put schools in the capital at risk of closure.^[67] Acton and West London College is a successful example of small site public land being effectively densified to deliver 120 new homes on an underutilised school site, unlocked using a public street.^[68]

But smaller sites remain subject to significant regulatory expectations and demands. And these smaller sites, like Acton and West London College, are simply not worth enough for larger housebuilders to redevelop – leaving SMEs at the mercy of the many taxes and regulations we cover in our section on brownfield land.

How to identify and effectively bring forward more publicly owned sites for housing

To enhance the pipeline of publicly owned land available for development, all public bodies should be required to produce an asset management strategy that identifies underutilised sites that are vacant, partially vacant, particularly below local average densities, or no longer required for their current public use. This should culminate in a rolling five-year optimisation pipeline of sites to be brought forward for development, disposal, or partnership, with clear delivery timelines and progress updates. Where authorities fail to deliver on these sites, or progress on applications stall, the Secretary of State should call these sites in for determination.

Where underutilised land is identified, policy should shift from viability-challenging expectations on affordable housing quotas to a presumption in favour of development to encourage and support housebuilding. Especially where public land assets are underperforming, serving suboptimal local populations to the risk of closure, or within 1km of a Tube station, there should be a clear presumption in favour of publicly owned land development written into the London Plan.^[69] This would prioritise the intensification of public land through the provision of additional homes where they can sustain local services – including schools at risk of closure – and make best use of existing infrastructure. This presumption, essentially, must be paired with a reduced share of affordable housing requirements.

For larger sites there is another option: Crown Development Orders. The Housing Secretary should encourage larger public-owned sites to pass through the new Crown Development Order process, given that housing building in London is of importance to the national economy. That would shorten the time window by enabling developers to apply directly to the Secretary of State, who could jointly consent new public services alongside new homes.

Brownfield Land

Brownfield land is previously developed land. In a land-constrained city, shaped by low densities and Green Belt restrictions, derelict and empty brownfield sites present the opportunity to deliver housing in high-demand areas, with the capacity to deliver approximately five years’ worth of London’s housing targets.^[70]

London has historically delivered most of its new housing on brownfield land. Between 2006/7 and 2020/21, the percentage of new residential development completed on previously developed land ranged from 95.7% to 99.8%.^[71]

Policy encouraging the regeneration and intensification of brownfield land is explicit across national and London planning frameworks. The new National Planning Policy Framework puts substantial weight behind approving planning applications in already developed areas.

However, the NPPF will be less effective in London due to the variety of competing planning objectives that come with the redevelopment of brownfield land. The London Plan contains over 500 pages and 113 different policy areas; each of these are too often treated as absolute requirements rather than as guidance.^[72] This creates a system in which policies conflict with one another, limiting rather than supporting the extent to which brownfield can deliver more housing.

The delay of Shoreditch Works is a key example. This is a brownfield development with an application swelling to 9,084 pages demonstrating compliance with 42 separate Hackney policies, 75 separate London Plan policies, and national legislation and guidance.^[73] Among the reasons for the rejection are competing policy priorities. For example, the development will not deliver enough homes, because the borough of Hackney is already delivering too few homes. But the development must also be no higher to accommodate a greater number of units, because it is already too tall.^[74]

To address this, a clear, strong presumption in favour of brownfield development within the London Plan should be introduced to streamline decision-making and resolve policy conflicts, as called for in the 2024 London Plan review commissioned by then-Secretary of State Michael Gove. This mirrors the language in the new NPPF, but also helps to resolve the conflicting policies, which can stymie development.

The London Plan should include the following presumption:

‘There should be a strong presumption in favour of granting planning permission for residential development on previously developed (brownfield) land within Inner London Boroughs.

‘Where a proposal meets this requirement, substantial weight must be given to the benefits of delivering additional housing in the capital. Planning permission should be granted without delay, unless the adverse impacts of doing so would significantly and demonstrably outweigh the benefits of development.

‘In applying this presumption, decision makers should take a flexible and proportionate approach to the application of policy requirements, including affordable housing, where it is clearly evidenced that such requirements would render development unviable or undeliverable.’ ^[75]

A presumption in favour of the development of brownfield land will not, on its own, go far enough to expedite the delivery of more homes in London. Brownfield sites are complex and capital-intensive: they require extensive remediation, added to by higher labour costs, and specialist contractor fees – alongside a steep 21.6% increase in landfill taxes in 2025.^{[76] [77]} These costs can only be recovered at sale.

There is too little financial relief to offset these costs of developing brownfield land, despite the public benefits associated with its development, including the remediation of contaminated land and additional new homes. Existing programmes, including the Brownfield Land Release Fund, have had little impact. The programme is applied nationally, utilising £68m to release enough land for 5200 homes; only about £12.4m went to London councils.^[78] But such a programme applied to the scale of brownfield needed to develop London’s homes would be at significant cost to the taxpayer.

The Government should expand full expensing to cover brownfield regeneration projects. This would enable homebuilders to fully deduct their eligible costs, such as land remediation, infrastructure, and construction, in the year that they were incurred rather than spread across multiple tax years. Full expensing will unlock investment into bringing brownfield land back into productive use and lower financing costs without reducing overall tax revenue.

Biodiversity net gain is a key challenge blocking the delivery of homes on brownfield land

Biodiversity net gain (BNG) is a prohibitively expensive policy requirement that reduces the potential for homes to be delivered on brownfield land. Introduced by the Environment Act 2021, it insists that developments covering more than 0.25 hectares of habitat must contribute to a minimum 10% increase in habitats.^[79] This came into force in early 2024 and is significantly disruptive on small sites.^[80]

Applying BNG equally to London as to the rest of the country does not simply risk constraining development where land is already scarce, but ignores the economic and social value of delivering housing in the capital relative to the marginal ecological gain achievable in London.

London already has 3,000 parks and a network of diverse green and blue spaces to facilitate biodiversity.^[81] Thwarting development on BNG grounds risks development spilling out into the countryside, incurring greater damage than if we allow London to build by exempting development from this restriction.

Further to the ongoing consultation considering a targeted BNG exemption for residential brownfield development, London brownfield should be exempt from BNG requirements.^[82] Building homes on a disused car park in London creates far less ecological harm than building homes on green fields. Yet both of them have to go through expensive surveys and monitoring that can add thousands of pounds to the cost of delivery.

Environmental Impact Assessment screenings add unnecessary burdens to the development of brownfield land

Brownfield developments in London involving more than 150 homes, or an area of at least 0.5 hectares, are subject to environmental impact screening requirements that are unusually stringent by international standards. In practice, this can generate documentation running to over 100 pages, alongside costly and time-consuming consultation processes, before a determination is even made as to whether a full Environmental Impact Assessment (EIA) is required.^{[83] [84]}

While these requirements originate from an EU directive, the UK applies them far more stringently than comparable European countries. For example, in the Netherlands, residential developments typically only trigger environmental screening at a much higher threshold of 2,000 homes or 100 hectares.

This disparity imposes disproportionate costs on urban brownfield schemes in London, where sites are smaller and margins tighter. As a result, developers face significant upfront burdens even where the likelihood of meaningful environmental harm is limited.

For the whole of the UK, the Government should raise screening thresholds, particularly for brownfield development in high-density urban areas, reducing unnecessary administrative burden and maintaining robust environmental safeguards when they are most needed. This can be done under secondary legislative powers by the Secretary of State to reform Schedule 2, 10 (b) of The Town and Country Planning (Environmental Impact Assessment) Regulations 2017.

3) Making the most of existing properties

Giving homeowners greater choice

Much of this paper has been focused on finding sites for new, dense development. These sites will have a large role to play in delivering the homes that London needs. However, the truth is most of London’s developable land area, especially in outer London, is already built on by single-family homes.

Attempts to build more in such areas have faced backlashes in the past. Replacing some of these homes with flats would increase density, as seen in Croydon’s small site policy from 2019-2022. In this case, the council implemented a suburban design guide (SDG), which meant existing detached homes could be torn down and replaced by small blocks of up to 10 homes.^[85] The policy was a success: housing delivery in Croydon doubled while the Suburban Design Guide was in place, outstripping other London boroughs. Housing also became more affordable as a result of the extra supply.^[86] But this rate of development was unpopular with local residents. Ahead of the 2022 local elections, both the Labour and Conservative candidates for Mayor of Croydon stood on pledges to withdraw the SDG.^[87]

Fortunately, there are better ways of building upwards while reducing the potential for political fights. Loft extensions enable an extra storey to be built on existing family homes. Extra rooms increase the flexibility of the housing market. Homes could grow upwards alongside a growing family, or the additional room could be let out to a lodger or friend. This extra space could also help a family member who wants to move to London to work or study, a parent who needs care, or a relative whose job requires them to be in London a couple of days a week.

Sadly, the current system of permitted development rights (PDRs) leads to smaller and less useful extensions. For example, any extension may not be higher than the existing ridge line, which means the new rooms have low, cramped ceilings. Likewise, extensions are limited to just 40 cubic metres of additional loft space for terraced homes and 50 cubic metres for semi-detached and detached houses.^[88] That severely restricts the extra floor space that can be added, effectively eliminating the chance of adding two full double bedrooms.

The differences between an existing terraced home, the maximum current permitted development loft extension and a complete loft extension, also called a Great Green Loft. The green area on the right shows the potential uplift if we rationalised our permitted development standards (Source: Populo Living)

Extensions like the one above on the right have to go through the full planning process. Right now every local authority has their own rules relating to what sorts of extensions are allowed, which creates uncertainty and delay, and in many cases effectively bans these beneficial extensions.

To allow homes to grow up, the next Housing Secretary should amend existing permitted development rights to remove the cubic area restriction, give more flexibility around the ridgeline, and remove the arbitrary 0.2m set back requirement for where the loft starts.

In London, this tweak would provide the opportunity for between 450,000 and 900,000 additional bedrooms.^[89] This would provide a huge opportunity for small builders who have almost completely been pushed out of London housebuilding. This scale of project could be managed by a local builder who will know the area and be proud to improve it.

Similarly, the previous Government consulted on changes to permitted development rights.^[90] These included allowing larger and more useful extensions that rise to the roofline, better guidelines for loft extensions, and allowing permitted development rights to apply to older homes. But MHCLG has not made progress. The next Housing Secretary should implement the tweaks within the 2024 consultation which will allow Londoners, and the rest of the English, greater rights over their own homes. This will also enable more rear and side extensions.

One complicating factor is conservation areas. There are currently over 1,000 conservation areas in London. In some boroughs, like Camden or Hammersmith & Fulham, they take up half of the borough’s land.^[91]

However, conservation area status should not lead to an automatic ‘no’ towards any development. After all, historically these areas would grow. The Strand, for example, started as a street of one- and two-storey buildings, before gradually expanding upwards to the six to nine storeys we have today. Similarly, it was common for Georgian or Victorian homes to have roof or rear extensions if the family living there needed extra space.

Tower Hamlets provides a good example of allowing expansion while respecting the conservation area status.^[92] After campaigning by local residents, the council published guidelines permitting roof extensions within strict frameworks, and design guides meant to mirror traditional mansard extensions.

Examples of roof extensions within a Tower Hamlets conservation area that match traditional designs

Similar to the Tower Hamlets example, residents in South Tottenham demanded the ability to add space to their homes due to overcrowding. A new Supplementary Planning Document allowed the addition of all full storey and a loft extension while introducing visual requirements to ensure that the redeveloped properties matched the existing character of the neighbourhood. Over 200 households out of 1,000 eligible properties took this opportunity, which can pay for itself through the provision of valuable, extra floor space.^[93]

The Housing Secretary should confirm that historically appropriate roof and rear extensions do not constitute a harm to conservation areas within the National Planning Policy Framework and that extensions are useful both for creating additional homes and for adding additional residential space. The latter point is important because L2.1.D of the draft NPPF currently only encourages expansion of existing homes if it leads to additional homes. This text should be updated to ‘additional residential space’ to not restrict current homeowners unnecessarily. And in learning from the Tower Hamlets and South Tottenham examples, the Housing Secretary should encourage local planning authorities to create design guides for acceptable roof and home extensions within and outside of conservation areas.

This work could be accelerated through a statutory national development management policy (NDMP). The Housing Secretary should issue a statutory NDMP creating a national ‘yes unless’ rule for household extensions that require a planning application, while narrowing the scope for local plans to impose inconsistent tests or damaging regulations. That would tip the balance in favour of home extensions, helping empower existing homeowners to make their properties the best for their families. Such an NDMP should also explicitly state the reasons why an extension could be refused, which could include cases of a loss of privacy, failure to meet building safety requirements, or damaging a listed building.

Finally, the necessary secondary legislation for street votes should be passed. This will allow homeowners in London even more flexibility about the future of their homes and streets. Should a supermajority of residents vote in favour of a plan for gentle intensification, they should be allowed to grant themselves planning permission and capture the large uplift generated.

Change of use

Increasing the supply of housing in London goes beyond just building more new homes. The next government should also look to increase the flexibility of the buildings that we do have already, whether it be the many disused shops on London’s high streets or office buildings that are no longer used after the shift in working patterns post-Covid.

One of the authors of this report lives in a converted factory. The site was a booming Victorian centre of production, but by the 1970s had fallen into disrepair before finding new life decades later. The conversion has successfully brought the site back into use while providing hundreds of homes.

However, since the successful regeneration, the guidelines have changed in a way that would make such a conversion impossible. Due to its listed status, the factory could not now be modified to provide private outdoor space to every flat. The size of the buildings makes following the dual aspect rules (which hold that flats should have light from two sides) almost impossible. Similarly, the London Plan’s housing design standards would make it complicated to retain the large windows of the original factory, and would frown on the north-facing orientation of many of the single-aspect flats. This example shows how new regulation often either adds costs to regeneration projects or blocks them outright.

The Mayor or the Housing Secretary should change the London Plan to scrap regulations that prevent conversions such as private outdoor space, dual aspect, and stringent accessibility standards.

The previous government expanded permitted development rights to make it easier to convert certain buildings into homes. However, this power is limited in London by both local councils and the London Plan. Local authorities are able to create Article 4 directions, which force these conversions to go through a full planning application rather than being waved through automatically. These are often used to force developers into paying Section 106 contributions towards affordable housing, which they would not have to do under PDRs.

Additionally, the London Plan discourages new housing in the Central Activities Zone, which encompasses most of Zone One, if it impedes on the commercial and office-based nature of central London. This clause is used to oppose the reuse of these spaces as homes.

To boost changes of use and increase flexibility in the buildings that we already have, the Housing Secretary should limit councils from creating Article 4 directions that stop easy conversions within central London. The Mayor or the Housing Secretary should change the London Plan to encourage housing within the Central Activities Zone.

When conversions are forced to go through planning, local authorities are able to further frustrate the process. Certain councils like Camden and Tower Hamlets require office space to be on the market for two or more years before a conversion is considered.^[94] To force a property to be out of use for more than two years before even beginning the planning and construction processes makes these conversions uneconomic. The fact that the building owner wants to change its use should be proof enough that the market factors in favour of homes are stronger than those in favour of office spaces.

Finally, a statutory National Development Management Policy should be introduced to explicitly encourage conversions and to ban councils from requiring property to be vacant while awaiting a planning application for change of use. The desire of the property owner to change its use should be enough to demonstrate market demand.

Social housing

At 21.1%, London has the joint highest percentage of socially rented homes in England by region.^[95] With 807,000 total social homes, London also has the highest absolute number of dwellings of any English region. Of all the OECD countries, only the Netherlands, Austria and Denmark have a higher percentage of homes that are rented out at subsidised prices.^[96] Yet for all its ‘affordable’ homes, London is the least affordable of any of the regions in the UK and one of the most expensive cities to live in throughout the world.

The latest English Housing Survey puts the average London private rent at £368 per week, compared to £157 per week for socially rented homes.^[97] That equates to £10,972 a year in implicit subsidy to each socially rented home, or £9 billion a year across all of London’s social homes. Socially rented homes in the capital are also larger on a per resident basis than privately rented homes, so tenants are paying less to get more.^[98]

That subsidy figure is also an underestimate, because it does not take into account the amount that the Government spends on Housing Benefit or on the housing component of Universal Credit. The former has an average annual award of £11,087 and is awarded to 265,000 London households, which makes a total cost to the Exchequer of roughly £3 billion a year.^[99] Unfortunately, there is no regional breakdown for the housing component of Universal Credit, but assuming the breakdown in regional spending is the same as housing benefit, a further £6 billion a year is being spent.^[100]

Taken altogether, it is likely that the Government spends more than £18bn a year subsidising people to live in London. Given this staggering amount, and the dire housing shortage within London, is the current way that the state gives out social housing and subsidies in this country’s most expensive real estate market serving the national interest?

The commonly given justification is that social housing in London is provided to essential workers. But this is wrong. Just 59% of working age households in social housing are in any form of employment.^[101] That’s compared to 85% of those in privately rented housing and 95% of households with a mortgage. Of all social tenants, one out of every six have never worked.^[102] The push by councils like Westminster to award lifetime tenancies also cuts against the argument that social housing is for essential and low-paid workers.

There is also a political point here. The 2021 census showed that 47.6% of social housing in London is let to people who were born outside the UK.^[103] This is estimated to cost British taxpayers £3.6 billion a year in discounted rent.^[104] Now of course, a lot of the people will have since naturalised to become British citizens. But figures released by the ONS show that 120,000 social homes are headed up by someone who does not have a British passport.^[105] That equates to 15% of all social homes in London. If you asked British workers what they want their tax money spent on, they would almost certainly not say that it should go towards subsidising new arrivals (especially non-workers) to live in some of the country’s most attractive and desirable areas.

The next Mayor and Government should want London’s social homes to be allocated fairly. While at the same time, the huge implicit and explicit subsidies that the state provides to households living in the most expensive city in the UK must be recognised and reduced.

Sell expensive council homes when they become vacant

As London’s house prices have risen over the past half-century, so too have the values of social homes in the capital. This can lead to absurd outcomes, like million-pound council homes.

Social housing should not be a lottery for subsidised mansions. Buying a million-pound home would involve mortgage payments of roughly £4,500 a month, yet the median social tenant in London only pays £550 a month in rent.^[106] That means that the subsidy for such properties could be as high as £50,000 a year.

There is a way to solve this unfairness. The Housing and Planning Act 2016 gives the Secretary of State the power to mandate local authorities pay a sum equivalent to the amount of higher-value vacant council housing that comes up each year. In other words, it provides local authorities with a strong incentive to sell valuable council properties when they become vacant. The legislation also mandates that the revenue from such sales should go towards building more, better-value social and affordable housing.

The Housing Secretary should use this power to force the sell expensive social housing, with proceeds spent on building more homes for affordable rent. Expensive social housing should be defined as any social home that is valued at more than the London average price for a property with the same number of bedrooms.^[107] Before the 2016 Act, ministers suggested what these amounts might be in London.^[108] Adjusting for house price inflation, the numbers provide an indication of what higher-value council housing should be sold off once it becomes vacant:^[109]

• 1-bed: £400,000
• 2-bed: £460,000
• 3-bed: £570,000
• 4+ bed: £910,000

Savills estimated in 2015 that such a plan, implemented across the country, would raise £3.2 billion from 5,500 annual sales, with London contributing the most valuable properties.^[110] The money raised from the sale of these expensive properties can then be recycled into the construction of affordable homes to help tackle London’s growing number of people living in temporary accommodation.

A national cap on housing benefit

Housing benefit and the housing component of Universal Credit have become enormously expensive. Taken together, Great Britain is spending £37.3 billion on housing subsidies, which is by far the highest amount in the OECD as a percentage of GDP and almost double France, which is the next highest spender.^[111]

One reason for this high expenditure is that housing benefit is meant to cover the cost of rent for a property in the 30th percentile of market rates within a claimant’s local area. A claimant in Central London is entitled to four and a half times as much in housing UC as claimants in Durham when renting a two-bed property.^[112]

In addition to the staggering cost to the taxpayer, the current policy distorts the housing market. There is no incentive for claimants to move to cheaper areas, as the only result is a decrease in their benefit claim. Likewise, claimants are subsidised to live in areas with dire housing shortages, which drives up prices and rents. That harms working people who are not on welfare.

The next Housing Secretary should impose a national cap on future Universal Credit housing claims set at the median national rent. That would mean future claimants would receive either the 30th percentile rent in their Broad Rental Market Area or the median national rent, whichever is lower.We should not be subsidising people to live in properties that are more expensive than what the average British family can afford. Existing claimants should be grandfathered in on their existing rates to avoid any unfairness. But we would no longer be subsidising new claimants to live in the most expensive areas, while reducing Britain’s eye-watering welfare bill.

Revive the Right to Buy

We should want both to encourage property ownership and for social properties to bear the full weight of the implicit subsidy that they receive so that the homes go to the people who value them the most. Ownership is desirable both as an end in itself and as a means for individuals to gain a stake in their local community.

Ownership also has the added benefit of potential productivity increases through win-win transactions. Existing social tenants may feel that their home does not match their needs any more, or perhaps may want to cash in on some of the equity in their home by moving to a cheaper area. Likewise, perhaps a family may want to move to London to make the most of the job opportunities.

There’s a genuine win-win outcome here, where both the existing social tenants are better off and the buyers of the home are happy too. These win-win outcomes are only possible under the current system because of Right to Buy – yet the current Government has announced that it is clamping down further on Right to Buy, for example exempting newly built social homes from being eligible for 35 years.^[113]

Right to Buy has already helped two million families own their home. Reviving and expanding it would boost home ownership and give millions more a foothold on the property ladder.

The most basic step in improving the existing system is to reverse Labour’s changes to the Right to Buy and expand the existing Right to Buy from local authority tenants to housing association tenants as well. That would more than double the number of London social rent households who have the ability to buy their own property.

But to go further, the next Housing Secretary should introduce a new and better version of the Right to Buy, as proposed by Alex Morton for the Centre for Policy Studies.^[114] This would see every housing payment, excluding housing benefit, go towards paying off a mortgage secured against the property. A mortgage worth 60% of the value of the property would be secured on the property, backed by the government. Repayments would be set at the rent the year the mortgage was taken out, with the housing payments rising as social rents do (currently CPI +1%). The increase above the starting payment functions as the ‘interest’ payable on the mortgage.

Then as the tenant makes payments, they would build up equity. Once they paid off their 60% mortgage, they would obtain full ownership of the property. The existing equity could also cover housing payments if the tenant lost their job or had a change in personal circumstances. This would encourage more flexibility over the use and allocation of social properties in the future compared to the present system. The full details of this scheme are beyond the scope of this paper but can be found in Alex’s report.

This version of the Right to Buy has four main advantages for tenants compared to the existing right to buy system that makes it more attractive for gaining ownership:

1. The tenant has support if they lose a job or a relationship breaks down. Under the existing right to buy system, they run the risk of being dispossessed if they fail to keep up with mortgage payments.
2. The local authority or housing association would continue to cover large scale maintenance costs, while the resident would cover minor maintenance costs around their home like blocked sinks or broken appliances.
3. This system still enables access to housing benefit, although those payments do not go towards building up equity. The lack of housing benefit is a big disincentive to go through with a right to buy purchase.
4. And finally, initial costs are lower for the resident. Mortgages are most costly at the start given the bulk goes towards paying off interest as equity slowly builds. That provides a helpful boost for households to get on the housing ladder.

4) Policies and Regulations

In the previous two chapters, we have pinpointed specific areas where London should build, as well as outlining how we can make better use of the existing housing stock and spur extensions, densification and a better allocation of housing stock, in particular by ensuring that London is home to more homeowners and productive workers.

But there are a whole range of other policies, set at both local and national level, that need to be improved, from the inadequate housing targets set for London to the affordable housing targets that burden viability.

In this final chapter, we will examine those issues, before taking a granular look at the precise regulations that need to change at both a local and national level, and the role played by the infamous Building Safety Regulator.

Reforming housing targets to spur delivery

The Government has revised and strengthened the system of housing targets. But where they remain unmet, as is too often the case in London, they become meaningless.

London is building nowhere near its housing target. Between 2021-2024, London built just 36% of its old, planned 99,000 homes a year target on average. Every single other English region managed far more building compared to its target, with the average region building 94% of its goal. The East Midlands, North East, North West, and Yorkshire all exceeded their targets.^[115]

In fact, London has not built close to its new target of 88,000 homes in a year since the 1930s. Partly this is because, even when national targets are increased, the impact in London is limited.

Borough housing targets are not set directly by the national standard method, but by the London Plan, which in turn is used to inform borough plans. The current plan was published in 2021 when London’s housing target was 52,000 homes a year.

The new London Plan is not expected until 2027, potentially 2028. This enables boroughs to continue undercutting their share of the new target for the foreseeable future as local plans are able to be locked in for five years. This exposes London to a significant risk of underbuilding by tens of thousands each year even with proposed reforms to the housing targets and policies that would expedite planning permission. A solution is to ensure that as national targets increase, each borough increases its contribution in proportion to its current share of the target.^[116]

That said, targets only matter if there are consequences if a local authority fails to build. Without credible consequences for under-delivery, local authorities may simply plan for fewer homes or slow approvals in response to political pressure from local residents. Across the country, it is common that local authorities miss their annual housing targets. But in London, councils missing their targets compounds into significant losses for the capital.

In 2025, it was found that 10 London boroughs delivered less than 75% of their annual housing targets under the Housing Delivery Test. In the first quarter of 2025, 23 of the 33 boroughs across London recorded zero new housing starts.^[117]

London councils are also the least likely to decide an application on time. Only 12% of major planning applications were decided within the initial 13-week target in London, the worst performance of any region, and well below the English average of 20%.^[118]

To prevent this from happening and to ensure new homes are delivered across the capital, local authorities should be penalised for not meeting their housing targets where applications have been submitted. The planning system already contains mechanisms that could support stronger enforcement. The Housing Secretary should use their powers under s62A-B of the Town and Country Planning Act 1990 to designate underperforming London councils. That allows applicants to choose to apply for planning permission directly to the Planning Inspectorate, rather than waiting for a response from a council that is already missing its planning decision goals and housing targets.

There are more policy levers to build homes in areas that are underperforming their targets. The Housing Secretary could choose to use their powers under s15GA of the Planning and Compulsory Purchase Act 2004 to revise the local plan of underperforming London councils. Additionally both the Mayor and the Housing Secretary have powerful call-in powers which allow them to review and approve planning applications as they see fit. If there are significant housing or commercial developments that risk rejection or delay, the Mayor or the Housing Secretary should use their call-in powers and approve them.

The Government’s new housing target understates the number of homes needed in London

In 2024, the Labour Government introduced a new standard method to calculate housing targets. London is the only region where housing targets fell, from roughly 99,000 homes a year to 88,000. All other regions saw their targets rise. Given that London has the worst housing shortage of any of the regions, a reduced target is completely illogical and exposes an inadequate allocation mechanism.^[119]

The revised housing need method calculates targets in two stages. First, a baseline need is set at 0.8% of existing housing stock. Second, this figure is increased where housing is less affordable, using the house price-to-income ratio averaged over five years. While this affordability adjustment increases targets in expensive areas, London’s overall target fell compared with the previous method because the baseline calculation is now tied to existing housing stock rather than higher population growth projections. But in a city which has historically had housing delivery significantly lag behind population growth, the housing stock is an insufficient baseline.

A better approach would allocate homes according to median house prices minus bare construction costs. This method reflects a core market signal: where the gap between prices and build costs is large, there is strong demand and weak supply, and more homes should be built.

Housing targets should be set according to median price to build cost ratios, based on local authority house price data and estimated basic regional construction costs, multiplied by average floor area.^[120]

This approach would ensure London absorbs a greater share of national housebuilding. London currently absorbs 22% of the national housebuilding target. Under the new method proposed, London’s annual housebuilding target would rise to 145,000 homes, representing 39% of national housing delivery.^[121]

This will significantly increase the housebuilding targets applied to London and its individual boroughs. It will equally reduce the pressure on councils across the country, where demand is lower and less economically viable. Of course, there will still be a need to build homes in these areas – but this metric will be more sympathetic to the local economic circumstances.

Our housing targets let London off too lightly

Other regions have to build more than their share because the capital builds less.

Chart: CPS and Onward^[122]

Affordable housing requirements and developer contributions

The London Plan expects that every private housing development has 35% affordable homes.^[123] High affordability requirements might sound like a way to deliver more cheap housing – but they actually function like a tax on new development. When the Mayor or councils mandate that a given share of new homes must be let or sold at below-market prices, the cost of construction does not vanish. Instead, it is shifted onto the developer, who will then pass the cost on to the remaining market-rate homes.

In practice, this reduces the financial viability of projects, especially on marginal sites, and deters new supply. The effect is the same as imposing a tax: it makes building more expensive and less likely to happen. If a building cannot meet the 35% requirement, there are viability assessments, which can be used to allow a development to proceed with a lower contribution of affordable housing if a higher share would simply make the project unviable. But these mechanisms are neither automatic nor frictionless. They typically involve lengthy negotiations and complex financial disclosures which are difficult to predict in a turbulent market – while still carrying the risk of refusal. Countless large schemes have been held up or rejected by this hidden tax.

We call this a tax, because the cost is borne by working people who are forced to pay more for housing as a result. It is also borne by landowners in the form of lower land values, and developers in squeezed margins, which strongly discourages them from building homes in the first place.

Taken together, this is wealth redistribution through the planning system rather than through transparent public spending. If the government wants to build more subsidised housing, it should pay for it out of general taxation, not the distortionary affordability targets.

Even Steve Reed, as Housing Secretary, acknowledged that affordability requirements block delivery. After London’s annual housing starts dropped to fewer than 5,000, Reed ordered Sadiq Khan to temporarily lower the affordable percentage from 35% to 20% on most sites. The associated consultation said that ‘reducing the affordable housing thresholds…is designed to encourage development to come forward’.^[124]

These are welcome steps, but they do not go far enough. And as mentioned above, if these measures will get more houses built, why are they temporary rather than permanent?

Moving chains means new market rate housing benefits households of all incomes

Building more market-rate housing obviously benefits the people who move into the new homes. But the benefits ripple out further.^[125] The buyers of a new home move out of their existing house, which frees it up for someone else to move in to. That in turn frees up another home. This chain of moving can stretch across income divides. One study in Helsinki found that 55% of these chains reach households in the bottom half of the income distribution and 36% reach households in the bottom quintile.^[126] Another in Switzerland found that for every 100 new market-rate homes, there were 75 household moves among those below the median income.^[127] Put another way, the benefits of new construction helped working class families move into a better home 75% of the time.

An illustration of the moving chains that new supply opens up, which allow for moves across the income distribution and help to reduce overcrowding among the worst off (Source: Hauck and Kluser)^[128]

Supply and flexibility are what matters. If there’s anything close to an iron-clad law of land economics, it is that increasing housing supply makes housing more affordable.^[129] Homes England estimates that a 1% increase in the housing stock leads to a 2% reduction in house prices.^[130] By reducing the viability of new supply, affordable housing requirements can actually reduce affordability across the whole housing market.

Affordable housing requirements severely limit who is eligible

As mentioned above, most Londoners will see no benefit from new subsidised housing. The system prioritises acute distress rather than ordinary low-paid work. The result is that many working households are stuck in the worst of both worlds: too secure to reach the front of an ever-lengthening queue for social housing, but nowhere near affluent enough to comfortably afford the market rent, let alone get on the housing ladder.

A defender of social housing might suggest that intermediate rent properties, a subset of affordable housing, are more appropriate for working families. Yet, distortions in intermediate rent properties can lead to absurd outcomes. For example, one three-bed intermediate rent flat in the City of Westminster requires a minimum household income of £82,600 to be able to afford the rent, but a maximum household income of £90,000 to still be eligible for reduced rent – and the household cannot have more than £100,000 saved.^[131] Having such a narrow eligibility range is farcical, rewarding people with inside knowledge of the allocation system at the expense of working families.

The next Mayor of London or Housing Secretary should remove affordability requirements from the London Plan. This will spur more construction, unlock marginal sites, and with the filtering effects mentioned above provide more affordable housing for households across the income spectrum.

This should not prevent the central government, local authorities or housing associations from building their own subsidised homes if they would like. Similarly, there should be no restrictions on central government, local authorities or housing associations from partnering with developers to purchase a percentage of homes and subsidise them. But funding for this should come out of general taxation, not distortionary requirements.

Importantly, a significant percentage of the savings from removing the affordability requirements could and should go towards the provision of additional local and regional infrastructure. Contributions towards infrastructure mitigate the harmful externalities that new development brings, such as more congested transport networks. In turn, the provision of infrastructure can drive sales for new housing developments, as with the Tube extension to Battersea Power Station and Nine Elms.^[132]

Indeed, beyond the subsidised housing percentage, the whole framework of land value capture needs to be improved. London’s developer contribution system should be simplified and turned into a unified Infrastructure Levy, excluding affordable housing contributions. This should be based on a share of development value and replace the current fragmented system, with revenues split between boroughs and the Greater London Authority to support both local and strategic investment. This would reduce delays, improve certainty, and ensure that developer contributions are more productively deployed.

The existing system is a primary source of delay to the delivery of new homes. The average time to reach an agreement between developers and local authorities across the country in 2024/25 was 515 days.^[133] In London, around 50,000 homes consented between 2019 and 2025 had not started construction due to Section 106 delays.^[134] Rather than case by case negotiations, there should be clear contribution formulas devised with industry to simplify and expedite contribution agreement decisions, instilling greater certainty into the system.

The legal powers to introduce the system in principle already exist. The Levelling Up and Regeneration Act 2023 provides the Secretary of State with the secondary legislative power to introduce a national Infrastructure Levy to replace s106 and CIL. A London-wide levy could be implemented within this framework.

Remove late-stage reviews

Another benefit of removing affordable housing requirements and simplifying value capture is the removal of late-stage reviews (LSR). LSR mechanisms allow authorities to capture additional developer profits where schemes outperform expectations – but offer no equivalent downside protection to developers who suffer amid the boom and bust of London’s housing market.

In effect, LSRs mean that local authorities and the Mayor capture most of any unexpected upside, while the developer carries the burden if the scheme faces any unexpected challenges. Put another way, heads the local council wins, tails the developer loses.

In the volatile macroeconomic conditions London finds itself in, characterised by construction cost inflation, higher interest rates, poor sale value growth, and delay after delay in the planning system, this asymmetric risk allocation is a disincentive to invest capital into housebuilding projects in the capital.^[135] LSRs also add to the cost of capital: the very investment required to fund housing delivery may demand a greater return to compensate for the risk, which ultimately could kill bids altogether by making the development unviable.^[136]

Late-stage reviews should either be removed and the initial agreement between the council and developer be maintained, or allow for downwards renegotiation if market conditions worsen after the initial agreement.

London Plan Rules

The London Plan 2021 is 542 pages, covering 113 policy areas. Each of these areas has individual policies associated with them, which taken together provide 541 different policies that applications can be assessed against.

There are many worthwhile regulations in the London Plan. It is right that we should use regulation to make well-functioning markets to internalise costs, guard our heritage and green spaces, and give homebuyers the assurance that they are buying well-made and safe new homes.

But the system as it stands is not working for anyone.

The London Plan’s policies, and housing regulations in general, can be divided into two categories. The first addresses genuine externalities, where new developments impose costs on others without compensation: noise, lost daylight, impacts on public services etc.

The second category, however, regulates costs that the developer and future occupiers already have every incentive to optimise themselves. A buyer who wants private outdoor space or a dual-aspect flat can simply refuse to pay for homes that do not meet these standards. Developers, who want to sell their houses, already have a commercial reason to deliver homes people want. Layering planning rules on top of these market signals does not correct a market failure. Rather, it overrides personal preferences, while reducing overall supply by pushing up construction costs and making sites unviable.

There are many regulations in the first category that we would amend. But as a priority for a new centre-right Government, we suggest that many if not most regulations in the second category should simply be eliminated, and replaced by a focus on the external impacts of construction. Indeed, New Zealand has explicitly adopted this externalities framework as the legislative basis for what planning can and cannot regulate. Their 2025 Planning Bill explicitly bans officials from restricting the internal layout of a building, dictating the provision of private outdoor space, or introducing tests of financial viability, among other examples.^[137]

The reason for this is simple. Each of these regulations functions like a straw on a camel’s back. Alone, they are easily managed by developers, and can even sound nice and sensible. But taken together, they impose significant costs that have held up the construction of much-needed new homes.

Some of these regulations even directly contradict others. For example, ventilation regulations and dual aspect requirements assume that windows are open to get a cooling draft. However, to meet noise regulations, buildings are assumed to have windows shut. Likewise, daylight requirements push for larger windows, while overheating guidance pushes for smaller windows.

Steve Reed already recognised that some of the regulations in the London Plan are too burdensome in his emergency measures for London housebuilding. Gone are dual aspect requirements, limits to the number of homes per core, and over-provision of cycle storage.^[138] These harmful regulations must not be allowed to be revived in future London plans.

But Reed’s de-regulatory push did not go far enough. Even with the removal of some of the most damaging regulations, the London Plan still weighs in on issues far beyond the reasonable level of regulation, with the result being fewer homes that cost more to build.

As the current Mayor prepares his second London Plan and the challengers in the 2028 Mayoral election start to think about what they may include in their own versions, it is worth studying the current plan to pull out regulations that are driving up costs and slowing down building.

Private outdoor space (D6.F.9)

If you look at recent new build developments in London, one of the most striking things about them is the preponderance of balconies that have been bolted on to the side. The reason for these balconies has not been an upswell of Londoners demanding them, but rather the addition of a policy in the London Plan to mandate a minimum of 5 square metres of private outdoor space per new home. The amount of outdoor space required rises as properties get larger.

Balconies or other private outdoor spaces are nice-to-have and many people would prefer to live in a place with one. However, this is not simply a costless regulation. The private outdoor space requirements are estimated to add between £10,000 and £20,000 to the cost of constructing a new home.^[139]

Private outdoor space requirements have broken the façade of this new building while adding thousands of pounds to the construction cost of each of the flats.

While many people may like a balcony, when given the option of having to pay that much more for it, it’s less clear that they would be willing to pay for it. After all, some of the most expensive and beautiful areas of London – like Mayfair, St James’s and Marylebone – tend not to have private outdoor spaces. Likewise, quintessential London architecture like mansion blocks rarely provide 5m² of private outdoor space, yet will still have significant buyer interest – especially if it is near to a park anyway.

This rule is especially damaging for conversions. Older buildings or office spaces were not designed to have private outdoor spaces, and as such, this regulation can significantly impede changes of use.

If people want to pay more for a balcony, housebuilders will build flats with balconies. If people would prefer not to spend £10,000 or more on a balcony, then they should be allowed to buy flats that do not have private outdoor space mandated.

Minimum space standards (D6)

Research from the GLA shows that the average renter in London consumes just 24.6m² of space.^[140] London flats are the most expensive in the country so it is not surprising that renters are not willing or able to pay for more space. Yet the smallest flats that can be built under the London Plan are 37m² for an individual or 50m² for a couple. That means the minimum space standard is 50% larger than what the average renting Londoner can afford. The Centre for Cities points out that this extra 12m² is almost exactly equivalent to the requirement to have a sofa and TV area from the London Housing Design guide.^[141]

The current minimum space standards restrict the options that renters have. Perhaps a young professional would like to live alone in her own flat, but there are not any at the size that she can afford. Because of the minimum space standards she is forced into a crowded flat-share. London’s 37m² is also above similar countries. France, Spain, Italy, the Netherlands, and Japan all set the figure at 25m² or below.^[142] The London Plan should be amended to follow suit.

Housing size mix (H10)

The London Plan requires developers to deliver a range of unit sizes, which is meant to be supported by local evidence of need or the London Strategic Housing Market Assessment. There is no reason why the London Plan has to weigh in on this and inadvertently distort the housing market. Developers are already very well-incentivised to deliver housing sizes that they think there is demand for. If they didn’t get the size of homes right, they are less likely to be able to sell them and make a profit.

Concerns about developers only building one- or two-bedroom flats are misplaced. If there is more demand for such flats, then developers should be allowed to build to meet it. Right now, when developers are not allowed to build enough one or two bed flats to meet demand, that demand does not go away. Instead it manifests in the conversion of existing ‘family-sized’ terraced houses into flats. To reduce this trend, which is unpopular with neighbouring residents, local authorities and the GLA need to avoid restricting what types of homes can be built.

Affordable workspace (E3) and affordable student accommodation (H15.A.4)

When building either office space or student accommodation, the London Plan requires a significant percentage to be given away at a rate far below market level. The affordable workspace policy caused significant amounts of confusion during the planning committee deciding the Shoreditch works scheme and was one of the reasons that it was deferred, rather than approved.^[143]

This is unlike almost any other type of transaction. A baker doesn’t have to give away a percentage of their bread. Plumbers can expect to be paid a market rate each time they’re called out. Pubs don’t have to provide some of their pints at a loss. Workspaces and student accommodation should be no different.

The current system also functions as a handout to less efficient businesses at the cost of actually increasing affordability across office spaces. If a business does not earn enough revenue to pay for its expenses, it should be allowed to go bust and be replaced by a more productive enterprise, not given a handout at the expense of the developer. As mentioned above, more supply leading to lower rents and land costs is as close as one gets to an iron-clad law of urban economics. By adding subsidy requirements, the London Plan is specifically making it more expensive to deliver this new supply.

Car parking restraints (T6)

The London Plan imposes restrictions on the amount of car parking that developers can include. This may make sense for central London, but it means that schemes in outer London do not have the level of car parking that future residents would like. In turn that makes it harder to sell the properties, which disincentivises the building of new homes in the first place.

For a lot of outer London, the standards mean that not every flat is able to have its own car parking space. When 45% of workers commute via car and 38% of all journeys are made in a car, not having a parking space is a significant disincentive to buy a house.^[144] The way to encourage public transport uptake is to make public transport better, not to level down the ability of households to have a car.

(We should also, as mentioned above, ensure that the temporary relaxation of restrictions on cycle space in Steve Reed’s emergency plan becomes permanent. In a world in which electric bicycles literally litter the streets of London, it seems increasingly silly to mandate that every building fill its ground floor or basement with bike racks.)

Minimising greenhouse gas emissions (SI-2)

London residents already have the lowest greenhouse gas emissions of any region in the UK. This is driven by dense urban lifestyles with lower transportation and heating emissions. The London Plan’s requirements to reduce emissions by 35% beyond Building Regulations go past the point of diminishing marginal returns. Every new building in London will already be energy efficient, certainly far more than buildings that they replace. By requiring ever higher standards, new buildings become more expensive to build, leading to fewer of them, and an increased reliance on older, less-efficient buildings.

Accessibility (D7)

Part M of the Building Regulations lays out accessibility standards for housing. The London Plan chooses to go above and beyond the basic standards. It dictates that at least 10% of dwellings must be wheelchair user dwellings, which is reasonable as this level of accessibility might not be provided by the market. Yet the other 90% of dwellings have to have the second highest standard of accessibility.

This standard, M4(2), requires step-free access and additional circulation and layout requirements. As a result, many beloved London housing forms are impossible. Narrow, terraced homes cannot meet M4(2) because of the requirements to have wide staircases. Walk-up mansion blocks cannot be built because entrances have to be level without steps. Conversions become more difficult because the existing buildings were not designed with this level of accessibility in mind.

A mansion block like this cannot be built in London today, partially because of accessibility requirements, despite its popularity with potential residents as seen by its £1 million flats (Source: Winkworth Maida Vale)^[145]

With London’s small, brownfield sites, this level of accessibility is often excessive. We should want the provision of wheelchair-accessible housing, but the requirement to make every home step-free adds more costs than the benefits it produces.

National Regulations

Second Staircase rules

While not in the London Plan, second staircase requirements are among the most damaging regulations introduced recently on new housebuilding in London. Announced in 2023, the rule mandates that all buildings taller than 18 metres, or six storeys, have two staircases. The official impact assessment found that the costs of this regulation would be 294 times the benefits.^[146] Yet as the Centre for Policy Studies showed, even this was a very significant understatement, because the assessment assumed that builders could make buildings taller or wider to offset the floorspace reductions from the second staircase.^[147] Given the constraints set by our planning system and the London Plan, these offsets are rarely feasible.

Putting in two staircases raises costs for buildings by reducing the amount of floorspace that can actually be lived in, while increasing complexity in construction. In many cases, to add a second staircase requires removing a flat from each floor of the building, which meaningfully reduces the number of homes a development provides. One estimate suggested that 18,000 homes a year are not being built because of the second staircase requirement.^[148] That’s made up of projects that are no longer viable, a flat being dropped from each floor, or developers shrinking their buildings to keep them below the 18-metre threshold.

In one case, Pocket Living, a developer, had plans to build 50 flats on a plot in Hackney. After spending £1 million on the site and its planning application, the introduction of the second staircase rule made delivery unviable due to site constraints. Instead of those flats, a mortuary will be built on the site.^[149]

The costs of second staircases are especially high for buildings between 18 and 50 metres. Yet the impact assessment predicted that lowering the threshold under which they are compulsory from 50 metres to 18 would not even save a single life over its 70-year modelling period. At the same time, this rule would impose £1.8 billion in costs. The result was that for buildings between 18 and 50 metres, the costs end up outweighing the benefits by more than 1,200 to 1. It is unsurprising that other countries, like France, Germany and Ireland, all chose 50 metres or above as their single-stair height limit.^[150]

The next Government should raise the second staircase height limit to 50 metres. This is especially wise given that new lift regulations reduce the need for firefighters to use stairs during a fire in the first place.

Parts F, L, O, and S of the Building Regulations

The last Government introduced several changes to national building standards, with Net Zero being one of the central rationales. The main changes updated Part F, which deals with ventilation, and Part L, which covers energy efficiency and conservation. Ministers also introduced Part O, which handles overheating, and Part S, which deals with the provision of electric vehicle charging.

These regulations have added significant cost to construction. The Building Cost Information Service (BCIS) estimates that taken together, Parts F, L, O, and S have added 7.4% on average to the cost of construction for a new home since 2021.^[151] Combined with surging material costs and the regulations mentioned above, these changes have made new homes less viable.

Part O in particular has restricted the quality of new construction. Air conditioning is treated as a last resort for cooling, instead of a go-to way of dealing with overheating. Part O also forces either a smaller glazing area or expensive dynamic thermal modelling and mandates a height of 1.1 metres above the ground. These combine to make for significantly smaller windows and effectively ban sash windows.

Age of the property is the biggest single factor in energy efficiency of homes. Just 12% of homes built before 1900 in England have a high energy efficiency rating, compared to almost all homes built in the past decade.^[152] New buildings with modern insulation will always be more energy efficient and emit less carbon than older buildings that they replace. Making it more expensive to build modern buildings limits the carbon emission savings while also encouraging older buildings to remain in use.

With this further strengthening of the building regulations, the Government has increased the cost of construction at the same time as macroeconomic inflationary pressures are driving up costs. By making it more expensive to build new homes, these policies mean less building, and more reliance on older, less-efficient buildings. The next Government should loosen Parts F, L, O, and S of the building regulations to lower the cost of construction and bring forward more homes.

The Building Safety Regulator

The Building Safety Regulator (BSR) was created with noble intentions. Established by the Building Safety Act 2022 following the Grenfell Tower fire, its purpose is to strengthen oversight of building safety and restore public confidence in high-rise residential construction. But it has instead dramatically slowed down housebuilding by increasing uncertainty, adding delays, and making many new homes in London unviable.

The biggest two risks for building fires are the age of a building and overcrowding. This is especially true in London, where demand is high, overcrowding is a significant risk, and a third of unsafe buildings are concentrated. New buildings reduce all of these hazards, but the BSR has stymied new supply.

The BSR has resulted in uncertainty, delay and capital constraints

The BSR regime introduces substantial uncertainty and costs into the development process through its Gateway system. This is a three-stage approval process designed to ensure safety compliance throughout the development lifecycle which instead incurs significant delays.

This challenge is most acute at Gateway 2, which requires detailed safety documentation of consented developments to be reviewed and approved by the BSR before construction. The exact requirements of this documentation are uncertain, forcing developers to overprovide and, through no fault of their own, clog the system. In 2025 it was reported that 75% of submissions progressing through Gateway 2 were rejected owing to missing or flawed information.^[153] And this comes at a significant cost: developers report spending between £12,000 and £25,000 on applications that were later rejected.^[154]

Although statutory timelines suggest delivery should happen between eight and 12 weeks, actual decision times have often been far longer. Median processing times are approximately 43 weeks overall and around 48 weeks in London.^[155] These delays reflect the regulators early stage learning curve, staffing constraints and multi-disciplinary assessment requirements, and industry adaptation to a new and complex safety regime.

The consequence of this Gateway has been a brutal shortfall in the annual delivery of homes for Londoners. The number of homes in the capital above 18m between 2019 and 2025 that had received full planning permission but had not yet started construction was 139,000.^[156] This represents not just fewer people who will have a home in the capital, but a growing share of people who will face overcrowding in unsafe, older, lower-quality accommodation as a consequence of bureaucracy.

The introduction of the BSR has also distorted development heights across London. Developers are avoiding mid-rise schemes that fall within the regulatory threshold, of 18m or six storeys. Instead, projects either remain below 18m or seek significantly greater heights given that the economics of high-rise construction can justify the greater cost of compliance. This has had a direct impact on the ability to deliver a greater share of homes across London through gentle density; either new builds are short, or towers are built but are scattered across the capital.^[157]

Reforms have been introduced to alleviate the backlog, but they have not resolved the underlying delays within the Gateway system. Reforms have included increasing the BSR’s staffing and technical capacity, introducing fast-track approval routes, more thorough guidance for developers to improve applications, and restructuring the body as a standalone regulator. Only three legacy cases are now in the backlog of Gateway 2.^[158] But all new developments must still individually progress through Gateway 2, which remains liable to delays.

A new risk to the delivery of homes in London is Gateway 3. This stage is required for constructed and renovated high risk residential buildings to be checked before occupation can legally begin, meaning developers cannot release equity and must continue to service borrowing while awaiting approval. But similar delays are arising and, as of January 2026, no new build high risk developments had yet applied for Gateway 3 approval.^[159]

The cumulative impact of the Building Safety Regulator is a legacy of declining viability. Developers have reported incorporating risk into their project timelines accounting for delays of up to 15 months beyond planning permission. Simultaneously, the BSR has worsened access to finance: according to industry, developers are struggling to access project funding until they have cleared Gateway 2. These issues can render projects unviable feeding into the decline of housing starts between 2023 (when the BSR came into force) and 2025.^[160]

As long as the Building Safety Regulator has the sole duty to enforce regulatory standards across individual applications, there is a risk of delay, and slowed delivery of homes. This creates a structural bottleneck for the regulator: as applications increase, as they must for the delivery of more homes, the system will once again face backlogs. A more effective model would be to introduce an economic incentive for building safety that moves away from a case-by-case system toward industry-level risk reduction achieved through the market mechanism.

One explorable option could be an insurance model for what are currently designated as ‘high-risk buildings’. In this instance, the government could introduce an alternative route to the BSR, through a risk-based insurance framework for high-rise development construction. Developers would be required to hold comprehensive fire liability insurance, with strict fire liability for defects that compromise safety. The premium that the developers must be responsible for paying becomes the price of risk: better detailing, safer materials and proven contractors lower the price, and poor practice raises the premium.

Insurers – owing to their incentive to minimise risk and need for predictability – would play a central role in scrutinising building design, materials and construction practices before insuring projects. By establishing a market, this would create a faster, more efficient layer of oversight that incentivises developers to comply with regulation rather than relying on a strictly centralised approval process which is delaying delivery. Another approach, perhaps complementary, would simply be for the next Government to raise the height of buildings covered by the BSR regime, ideally to the 50m threshold set in many other countries.^[161]

Conclusion and list of policies

London is a city steeped in history and culture. But its housing crisis risks being the defining domestic policy failure of a generation – and without immediate action, for generations to come.

In the time it has taken to write this paper, the number of mothballed homes in the capital has climbed to 42,000, and one of London’s largest developers has announced that it is halting land acquisition in the capital altogether. Each month of delay risks locking the capital deeper into a crisis that compounds as housebuilding slumps and the population of London rises.

The lack of homes has lowered the productive capacity of the capital, locked young workers and families out of ownership, and pushed the people London depends on, across every career and walk of life, out to commuter towns, or out of the country altogether. The UK cannot afford this.

The alternative is a London of growth, opportunity, abundant homes for Londoners and homes for those who aspire to become one. There is a clear path to this, as we set out in this report, with the potential for tens of billions of pounds being added to the economy every year.

The scale of response must therefore meet the scale of the problem. The proposals we lay out in this paper – including three new Mayoral Development Corporations covering London’s strategically most important sites, expanded estate regeneration with new planning and financing powers, the release of strategic industrial land and the release of public land, all emboldened by brownfield reform – would alongside our other recommendations result in the most ambitious housing intervention in London since the post-war reconstruction.

This report lays out the levers of power possessed by the Mayor of London and Secretary of State to build the foundations for the market to deliver. The proper role of government is not to step back from London’s housing market, but to loosen its grip – removing the barriers that prevent builders from building and leading through intervention where they must for coordination and scale.

None of this is a question of resources or technology. It is a question of the political will to use the powers already held by the Mayor and Secretary of State. To not do so is a political choice, and a misguided one: building in central London makes absolute sense for the centre-right.

The next Mayor and the next Government will be judged by whether they make these choices – and they will reap the benefits of doing so. The homes that London needs can be, and must be, made deliverable.

^[11] There is one important caveat which bears mentioning. London has the highest percentage of leasehold properties in the country. Mainly as a result of post-Grenfell fire regulations, raised insurance premiums, and the inflationary spike in building materials, services charges have outpaced inflation. This rise in service charges has suppressed home values and even made some properties unmortgageable. The challenges in the leasehold system is beyond the scope of this paper, especially given the unannounced scope of Labour’s reforms. Labour have pledged to introduce a Commonhold and Leasehold Reform Bill as part of the King’s Speech. Should these reforms prove unsatisfactory, more will need to be done to ensure that leaseholders do not bear the full brunt of Government’s cost increasing regulation and that new and existing homes have an attractive management structure for homebuyers.

The post Fixing London Housing: A centre-right plan to get London building again appeared first on Onward.

Britain is strongest when each generation keeps faith with the next. Those who have worked hard and contributed all their lives deserve dignity and security in their old age. But those who are starting out or in the middle of their working lives must not be asked to fund a system that will not be there to provide for them in their turn. That is the challenge that this report confronts, with honesty, boldness, and a refusal to pit young against old. 

It is widely understood in Westminster that our current pension settlement is under huge pressure and that this pressure is increasing. Our population is getting older, people are having fewer children, and the ratio of pensioners to working age people is deteriorating. The political choice to retain the Triple Lock adds huge cost and a volatile dynamic to this precarious situation. 

What happens when younger workers are asked to fund ever mounting costs while, correctly, doubting that the same system will keep them secure in old age? It is a social experiment we should be unwilling to run. At the same time, ending the Triple Lock is likely to be politically very challenging. And so there is cross-party paralysis regarding a policy that is unsustainable and is increasing our national indebtedness, but that is dauntingly difficult to assail. This has become a moral question: we must not allow ourselves to forget that the growing national debt is a claim on the labour, enterprise and earnings of people who do not yet vote and who in some cases have not yet been born. This is yet another reason that getting spending under control and prioritising growth are so vital, not only for us, now. But for them, tomorrow.

Even though reform of the current system will not be painless and must be radical, the answer is not to abandon pensioners. It is to move from a system of unpredictable and ratcheting costs to one based on clear, fair and durable rules, and this report lays out one vision for doing so. 

Onward should also be commended in treating pensions policy and family policy as deeply intertwined. That is the reality of our pay-as-you-go system, in which today’s children are tomorrow’s contributors. Making it easier for people to start and raise families is desirable not only because for personal, social and moral reasons we want our country to be a place where good lives can flourish, but because families are central to the long-term sustainability of the state and the support we want to be able to offer at certain times of life. 

Establishing a new settlement, that is financially sustainable into the future, that protects the old while commanding the confidence of the young and allowing them to move their lives forward, is a great and necessary task for policymakers in the coming decade. But not an easy one. 

Rt Hon Sir Jeremy Hunt MP

Chancellor of the Exchequer 2022-2024

1 Introduction

If society is indeed a contract between the living, the dead, and the unborn, then that contract depends on each generation receiving consideration from those who came before and then themselves making provision for those who will come after. Today in Britain, that balance is under mounting strain.

Young people find it increasingly difficult to reach the milestones that have traditionally marked a secure adult life: earning enough to live independently, buying a home, starting a family, and raising children without persistent financial anxiety. Most young people still want children, but many are delaying parenthood or having fewer children than they would like, with financial pressure one of the most important reasons. At the same time, Britain’s population is ageing, the ratio of workers to pensioners is deteriorating, and the cost of old-age entitlements is rising. The result is a growing gulf between the support older generations expect and what younger and future generations will be able to afford. 

This is not a zero-sum conflict between young and old and should not be portrayed as such. Older people have contributed throughout their lives and deserve security, dignity and predictability in retirement. Younger people want to start families because children and family life are valuable in themselves, not a mere national socio-economic consideration. But the current settlement compromises both sides of the intergenerational bargain. The State Pension is protected by the Triple Lock, politically attractive but fiscally volatile, increasingly expensive, and difficult for both households and governments to plan around. Pension spending is already one of the largest items in the public budget, and it will rise significantly as the population ages. Under less favourable demographic assumptions, the pressure could be greater still. Meanwhile, government support for families is often poorly timed, too weakly connected to the early years when costs are highest, and insufficiently responsive to the realities of childcare, parental earnings and household financial pressure.

In seeking to address these two problems together, this report from the think tank Onward and the Konrad Adenauer Foundation in the UK also seeks to more tightly bind the fortunes of older and younger people together. It proposes reforms that form the basis of a new intergenerational contract, that sees older people receive the support they need while helping younger people to get a fair start in life. It looks to honour social obligations to those who have contributed to our society and economy all their lives, and make sure that today’s young adults are able to contribute in their turn. Because if we do not fix our fraying social contract, the only certainty is that everyone will lose out.

2 Reforming the State Pension system

One in three working-age people say they do not believe that the State Pension will exist in thirty years’ time.^[1] In our pay-as-you-go system, wherein those now in work support those now drawing down their pension, that means a large number of people who are paying into the system do not expect to be able to benefit from it in turn. 

As difficult as it might be to imagine a world with no pensions or social security for the aged, our current state pension system is indeed threatened by spiralling costs caused by demographic pressures, low growth, and policy choices. The UK’s state pension is the second-largest item in the government budget after health, and the system is so unaffordable that major reforms will be necessary to save it. Though it has become somewhat more common in Westminster to hear this admitted, reform itself has not been forthcoming, with politicians understandably very nervous about floating changes that will make the system less generous for older voters. 

But getting ahead of the trends that are making our pension system unsustainable needs action which will take decades to work. That is why the time to act, and to clearly communicate to the public the need for action, is now, even if the problem appears to belong to tomorrow. This section of the report lays out why it is that the State Pension system has become so unsustainable and recommends a package of measures which can help governments to correct our course. Not only will such reforms help to ensure sustainable support for the old far into the UK’s future, over time they can lessen the fiscal burden on governments and help fund the policies we recommend in Chapter 3 to make it easier for more people to start and raise young families.

2.1 Spiralling costs

Older people, who have contributed much in taxes and in other ways throughout their working lives, represent a significant expense to the government, primarily in terms of health, social care, and pension costs. The expense of an older population makes it important that there is a proportionally larger working-age population, working and paying into the system now, and enabling the government to give older people the entitlements and the care that they need.

But as Chart 1 below shows, the UK has a rapidly increasing old-age dependency ratio, meaning the ratio of working-age people to those aged over 65. The old-age dependency ratio is by no means a perfect measure, particularly as more of us work later in life. Nevertheless, the very significant increase of the UK’s older population as a proportion of the working-age population does represent a fundamental challenge to the government, particularly in terms of maintaining old age social security.

Chart 1: Pension age persons per 1,000 persons of working age, 2024-80^[2]

As discussed above, this is because the UK has a pay-as-you-go pension system, so that the taxes of people working now are used to cover the costs of the State Pension for those who are retired. Fewer working-age people means fewer people paying in to support pensioners who are relying on their State Pension payments. 

In 2025 projections based on current policy, the OBR expects spending on the State Pension to rise from 5% of GDP today to 7.7% in the early 2070s.^[3] At the current size of the economy, that would see the State Pension costing £213 billion in today’s money, around £75 billion more a year than it does now.^[4] That is equivalent to, respectively, more than the entire annual defence budget, more than half of the education budget, and around a third of what we spend on health. This projection assumes that the number of adults of working-age to those above State Pension age declines from 3.4 today to 2.7 by the 2070s, meaning a smaller base of working people supporting higher pension costs. That is the kind of fiscal pressure that will absolutely necessitate some one or combination of significant tax rises, major spending cuts, or even greater levels of borrowing (assuming the latter is even feasible).

However, in making this projection, the OBR must make assumptions about the future, some of which are arguably highly optimistic. In particular, it assumes a TFR of 1.59 births per woman by mid-2045 which then remains at that level.^[5] The ONS’s latest 2024 based population projections are already less optimistic, projecting that UK TFR declines to 1.38 by 2029 and then rises to 1.42 by 2049.^[6] Since 2010, the ONS’s long term fertility projections have been consistently too high and required revision downward. The UK’s TFR is currently 1.39 and there is no guarantee fertility is about to rebound.^[7] As numerous international examples show, it is possible for developed nations to decrease in TFR far below this point and for extended periods of time. 

Similarly, and again in line with the ONS at the time in 2024, the OBR assumed net migration of 315,000 a year into the UK in forming its central projection.^[8] Already, the ONS has revised this projection down to 230,000 a year from mid-2027.^[9] However, much political will exists in the UK, across the political spectrum, for net migration to be much lower. 

The ONS itself publishes an ‘old age structure’ of its demographic projections that combines lower fertility, lower migration, and higher life expectancy. In the most recent version of that variant, from 2024, fertility is projected to fall to 1.22 in 2049 and net migration settles at 105,000 a year from 2027.^[10]

A simple stress test of the OBR central projection using the ONS’s ‘old age structure variant’ projection shows how State Pension costs could significantly rise under this plausible scenario. Using this official variant, the UK is projected to have just 1.85 working adults per pension-age person by 2073, compared with 2.7 in the OBR’s central projection. 

Mechanically scaling the OBR’s projection by that weaker support ratio could push spending from 7.7% of GDP to 11.2%. In today’s money, that would mean a State Pension bill of roughly £310 billion a year, nearing £100 billion more than that in the OBR central projection. That is the equivalent of a government having to find the money to hire an additional two million nurses, or build the Elizabeth Line five times over, every single year.

This should not be read as an alternative OBR forecast. It is a mechanical stress test. It holds constant the OBR’s assumptions about pension generosity, earnings, employment and GDP, and varies only the demographic support ratio.^[11] But the exercise is starkly revealing and illustrates how under plausible future scenarios the fiscal burden on the UK from its State Pension as currently designed could be far greater than is centrally projected.

In addition to this demographic pressure, the UK pension system is also strained by the ‘Triple Lock’, a policy which began life in the Liberal Democrat manifesto for the 2010 election^[12] and was adopted by the Coalition Government, likely as part of the horse trading of coalition negotiations. The Triple Lock guarantees that the state pension will be increased each year by whichever of the following metrics is highest: earnings growth; inflation (CPI); or 2.5%. 

The Triple Lock in part arose as a reaction to what happened when the Thatcher Government decided in 1980 to uprate the State Pension only by prices, breaking the earnings link.^[13] This saved successive governments money but meant that pensioners ceased to share in the rising living standards the rest of the country enjoyed. As a result, the State Pension fell from around 26% of average full-time earnings in 1979 to 16% between 2000 and 2010. This state of affairs and worries about pensioner poverty then ushered in the political conditions for the Triple Lock.

Politicians can be forgiven for not having given much thought to the Triple Lock when it was introduced. At the time, wages had persistently outstripped inflation in the past four decades – if the triple lock had been in place for those years, it would have more or less  amounted to an earnings link. But a long period of sluggish earnings growth and, in more recent years, high inflation, has made it absolutely unsustainable, leading to very significant jumps in value, as seen in Chart 2 below. 

Chart 2: The Triple Lock in action

Chart 3: Real Growth in the State Pension and workers’ earnings since 2011

In a further illustration of how serious the implications are for the UK public finances, in 2025, the OBR reported that the cost of the Triple Lock is forecast to be three times higher by 2030 than was modelled at the time of its introduction in 2011.^[15] The non-earnings linked element of the Triple Lock had been triggered in eight of the 13 years to date, because inflation “has turned out to be significantly more volatile” than had been expected.^[16]

The Triple Lock is a highly politically sensitive topic and politicians have been reluctant to discuss reform, when ever growing numbers of voters are direct beneficiaries of the policy. Because Triple Lock reform has been seen as politically challenging, governments have looked to another major lever in their effort to control cost: raising the State Pension Age. As we live longer, we have to work longer, and adjusting the pension age must play a role in calibrating the system. But there is an argument that the State Pension Age lever is subject to a hard limit in a way that uprating is not. This is because most people can try to do something about the level of their state pension, chiefly saving more during their working lives. By contrast, we can do very little about our life expectancy – it is essentially a fixed factor. 

Arguably, the most important test for state-provided, non-means tested retirement income (labelled ‘Pillar 1’ in international pensions literature, with Pillar 2 being private pension saving, and Pillar 3 being means tested help like Pension Credit) is to act as the ‘foundation’ income on which to plan your retirement. Some people have big plans which require lots of money, others want to wind down into a quiet, modest lifestyle. In both cases, knowing how much they need to be saving to hit their retirement goals is mostly dependent on how much State Pension they can expect to be getting. Under the Triple Lock, this is impossible to answer with any certainty. 

Firstly, we cannot know with any certainty how long the policy will be in place. It is a political commitment over which the main parties agonise over every five years. Secondly, even if we were certain, the way it operates produces results which will always run ahead of earnings and inflation, but it’s difficult to know how with much certainty. This makes ‘doing the right thing’ quite difficult for savers.

The uncertainty of the Triple Lock also forces the government to be more pessimistic about the cost of social security than potentially it should be, which is bad for the poorest pensioners. Long-term planning is basically impossible under the Triple Lock not just for savers, but also governments that have to administer it.^[17] Arguably this means prudent governments have to be very conservative when setting State Pension policy, whereas if the cost was more easily predictable, the public debate around it would likely be on different terms.

2.2 A generational three-part pension reform package

2.2.1 Reforming the Triple Lock

Recommendation: State Pension should be uprated according to a Demographics-Adjusted Earnings Link (DAEL)

As described above, the Triple Lock works by increasing the value of the State Pension each year by earnings growth, inflation or 2.5%, whichever is higher. The policy helped to increase the value of the State Pension after decades of erosion and has ensured that pensioners share in rising living standards. However, it is also expensive and highly volatile. 

In reforming the Triple Lock, two separate questions should be considered: first what the State Pension should be worth when someone first reaches State Pension age, and second, how the pension should be uprated once someone has retired.

One option for reform, which could control the cost of the earnings link in the long-term, particularly given demographic pressures, would be to only apply it to the value of the State Pension paid in the first year, and only uprate by inflation thereafter. After all, the State Pension is ultimately a benefit: when working-age benefits are uprated it is by inflation in order to protect purchasing power. 

However, there is a serious drawback with this reform, which is that over decades of receiving a State Pension uprated only by inflation, pensioners’ living standards will fall further and further behind the living standards of the rest of society. Particularly for those who rely heavily on their State Pension payments, this will mean rising pensioner poverty. To avoid such an outcome, there remains a strong case for retaining an earnings link in some form. The challenge is therefore not to abolish the earnings link but to make it more sustainable. 

To meet that challenge, this paper proposes that we retain the principle that the State Pension should rise with living standards, but adjust that link to reflect demographic pressure. In other words, the State Pension will rise in line with earnings but not automatically, or without reference to the number of people who are currently paying for it, a vital consideration in the UK’s pay-as-you-go system wherein today’s National Insurance contributors fund today’s pensioners.

The earnings link should therefore be adjusted or moderated by a demographic mechanism, which would reduce the earnings linked uprating when the base of contributors is weakening or when the number of pensioners is growing faster than the future workforce. 

Not only would this demographic slide put State Pensions on a more stable financial footing for the long term, but it would powerfully change the social contract that exists between older and younger voters. Binding the value of the State Pension to earnings and the demographic pressures the country is facing will also bind the fortunes and interests of earners and pensioners more closely together. For example, older voters will be incentivised to support policies that make it easier for young people to start families and be more focused on the barriers such young people face to doing so, including housing shortages or the expense of childcare. Japan has used a similar system since its 2004 pension reforms, using a macroeconomic slide that can respond to a decline in the contributor base or increase in the number of older people.^[18]

One way of designing a mechanism for Britain  would be through a two-part Demographic Slide, that subtracts measures of demographic pressure from the annual increase in the State Pension generated by earnings growth. The two demographic measures could be:

1. Current Support Ratio – The percentage change in the ratio of National Insurance payers to State Pension recipients, calculated over a three-year rolling average to avoid large swings from year to year
2. Birth Cohort Ratio – The percentage change in the size of the future workforce relative to the number of pensioners, which could be measured by looking at the number of live births registered in the UK N years ago. For example, if people usually start paying National Insurance at around the age of 21, births 20 years ago provide a rough indication of the size of the new cohort entering the labour market, which can then be compared with the growth in the number of pensioners.

The Demographic Slide formula could therefore work broadly as follows:

State Pension increase = earnings growth × (1 + weight on the change in the contributor-to-recipient ratio + weight on the change in the new-workers-to-pensioners ratio).

Where the weight is 60/40 in favour of the Current Support Ratio, to reflect its greater relevance to the current fiscal pressures affecting uprating.

However, to prevent the demographic slide from eroding the State Pension to the point that it no longer provides a sufficient foundation for retirement income, the formula should be subject to a floor, so that the value of the State Pension never falls below 28% of average earnings. This allows demographic pressures to moderate the generosity of the earnings link, but still gives people a predictable foundation upon which to plan and save for their retirement.

Projections suggest that this policy, of a DAEL with a 28% of average earnings floor, implemented in 2029 to reflect the current political commitment to maintain the Triple Lock until the end of this Parliament, would lead to State Pension spending of 5.58% of GDP in 2060. This is significantly below the 7.1% projected for 2060 with the Triple Lock in place and also below the projected cost of a pure earnings-based uprating (6.14%). By 2060, this policy would save the government around £30 billion a year in today’s money in comparison to a pure earnings link and £86 billion in comparison to the Triple Lock. Crucially, it does so without eroding the amount that the government spends on State Pensions as a percentage of GDP. In purchasing power terms, using the OBR’s CPI projections, it also means a 2060 pensioner is in fact 49% better off than they would have been in 2024.

However, it is important to understand that these projections use the ONS’s principal projection for births, which as discussed in section 2.1, may prove optimistic. In these circumstances, the effect of the demographic slide would be to reduce the uprating of the State Pension, except in circumstances where the 28% floor would kick in.

2.2.2 Automate increases in the State Pension Age.

Recommendation: The State Pension Age setting should cease to be a political decision taken every few years and instead should be set automatically with reference to life expectancy, using a smoothed mechanism that gives at least a decade’s notice of any change. 

It is right that as we live longer, we work longer. We already know that our pay-as-you-go public pension system works only as long as the ratio of payers to payees – all things being equal – remains constant. Life expectancy is one of the key factors determining whether or not that is the case, alongside other factors such as the relative sizes of generations.

This does not stop the pension age from being one of the most contested political issues a developed economy with an ageing population can face. Italy’s 2011 Fornero reforms, introduced during the eurozone debt crisis, among other labour law changes sharply increased retirement ages and linked future rises to life expectancy.^[19] Feeling against the reforms, the pension elements of which were in part rolled back, ran so hot that the minister whose name they bear was for some time not able to go outside without a guard of ten police officers.^[20] Government spending on pensions in Poland is already extremely high, estimated at over 11% of GDP,^[21] but with little political will to make cost saving changes like increasing the State Pension age. There is much to lose if such systems buckle under the strain and go bankrupt: state pension payments are the only source of income for 80% of EU pensioners.^[22] Variation in average life expectancy by socio-economic characteristics and debates over life expectancy versus healthy life expectancy further muddy the waters when reform is raised.

Today in the UK, setting the State Pension Age is a protracted political process which consumes a huge amount of government bandwidth – it is almost as controversial as the Triple Lock. A key reason for the controversy is because life expectancy rises are increasingly slower than the previous setting cycle anticipated.^[23] This gives the Secretary of State for Work and Pensions two options. Either commit to a setting cycle based on out of date life expectancy data (in recent years, likely to have deteriorated) or insist on sticking to the ‘⅓ of life spent in retirement’ commitment, which likely means picking a fight with the Treasury. The end result is – much like with the Triple Lock – that successive ministers are strongly motivated to kick the can down the road. For example, in 2023 the government declined to bring forward the State Pension age rise to 68 and instead left the question for a further review, which was launched in 2025.^[24] Yet in many other developed countries, including Finland, Greece, Denmark, Portugal, and the Netherlands,^[25] the pension age is set more or less automatically with reference to life expectancy, avoiding major political difficulties.

The UK should move to a similar automated system for setting the State Pension Age, doing so according to a formula that is primarily driven by life expectancy but that also aims for every generation to spend the same proportion of their life in retirement, which is currently around one-third. These changes should be designed to be gradual, with plenty of notice given so that people can plan and save accordingly. 

While life expectancy generally is still increasing, those increases have slowed, and the public debate around the last State Pension Age setting cycle centred around this exact fact. Some will argue that the formula should take account of healthy life expectancy, not just life expectancy, as the Tony Blair Institute recently proposed in the form of its ‘Lifespan Fund’ policy, which would use individual characteristics to actuarially personalise access to the state pension.^[26] While the concern is understandable, healthy life expectancy is too uncertain and subjective to serve as the trigger for automatic changes to something as important as the State Pension age. Healthy life expectancy varies significantly by region, income and occupation, and is much more difficult to measure consistently than overall life expectancy, requiring unwieldy levels of complexity in any policy that sought to include this measure fairly. 

The better approach is to keep the pension-age formula simple and objective, while protecting those who genuinely cannot work longer through other parts of the system. That could include more flexible access to private pensions on health grounds, stronger disability and sickness support, and targeted help for people in physically demanding occupations. The State Pension age should be set by a clear demographic rule; hardship and ill health should be addressed directly, not by making the whole formula less stable.

The government should commission an independent expert review to design a smoothed automatic mechanism for setting the State Pension Age, with a guarantee of a minimum of a ten years’ notice before any change takes place and using rolling averages of life expectancy projections to prevent short-term shocks causing major swings in the timetable. 

2.2.3 Automate the receipt of Pension Credit. 

A strong objection to Triple Lock reform flows from the desire to prevent increases in pensioner poverty and protect the pensioners who depend the most on their State Pension. But this is ultimately an argument for strengthening Pension Credit, not preserving the Triple Lock and all its problems. 

Pension Credit is the part of the pension system that is specifically designed and intended to protect the poorest pensioners and played a very significant role in reducing pensioner poverty in the 2000s.^[27] It is formed of two parts: Guarantee Credit, which is a means-tested element that tops up pensioners’ weekly income; and Savings Credit, which is a smaller additional payment for some pensioners who reached State Pension age before April 2026 and is not closed to newer pensioners. Currently, the problem with Pension Credit is that it does not reach enough of the people it is supposed to: in 2023 to 2024, only 62% of those entitled to the benefit received it, leaving up to £2.5 billion unclaimed, on average around £2,600 per year per eligible family.^[28]

To fix this problem and make sure Pension Credit is working as it should, the government should move towards automating Pension Credit awards. This can be done in two steps:

First, the capital rules should be simplified. Savings and investments above £10,000 reduce the award. But this rule makes automation much harder, because DWP cannot determine a claimant’s capital holdings without asking them what they are. Removing this requirement would be the simplest reform and would mean that HMRC and DWP know everything they need to know about whether someone is eligible for Pension Credit without a proactive application necessary. After all, Pension Credit is aimed at pensioners with very low weekly incomes and those whose incomes are low enough to qualify but have substantial liquid savings are unlikely to be a large group. However, this can be tested using the Family Resources Survey and DWP administrative data.

Second, HMRC should automatically share an applicant’s income details with DWP when they apply for the State Pension. This will enable DWP to automatically add Pension Credit to that applicant’s State Pension payment, thus removing the need for the eligible pensioner to apply.

Together, these measures can ensure that even as the Triple Lock is removed, more of the poorest pensioners are receiving the help they need and are intended by the government to receive. Finally, it is also the case that factors such as the introduction of pension auto-enrolment and the very significant increase in female labour market participation mean that the number of people who need to and will need to rely on Pension Credit is diminishing over time.^[29] This declining caseload may mean that, in time, the government can consider simply withdrawing Pension Credit. 

2.3 A Pension Reserve Fund?

The three reforms laid out above are intended to stabilise and strengthen the UK’s existing pay-as-you-go public pension system. A further question is whether the UK should supplement that system by creating a pension reserve fund.

As laid out above, currently the UK system works by using National Insurance contributions and wider tax revenues raised from the current working-age population to fund State Pension payments to the current generation of pensioners. Workers do this on the implicit understanding that the next generation will do the same for them. Now, because of people living longer, falling birth rates, and a greater share of the population reaching retirement, this system has become unstable. 

The proposed response of this paper has been to adjust the pay-as-you-go system itself, by automating the State Pension age and changing uprating policy. But a further reform that could be introduced would be to build a reserve fund in advance, so that some of the cost of future pensions is met not only by future workers, but also by investment returns accumulated over time. Around the turn of the century, a number of developed economies established funds of this kind, including France, Japan, Australia, New Zealand and Ireland. Their designs differ, but the core principle is similar: set aside public money, invest it in a diversified portfolio of higher-return assets, and use the proceeds at a future date to help support the public pension system during a period of pressure, thus smoothing out the pressure on younger and future generations. The UK has not taken this route, and an opportunity to establish a sovereign wealth fund was arguably missed in the 1980s, when revenues from North Sea oil were at their height. Instead, the Thatcher Government explicitly chose to return that revenue to the public in the form of tax cuts.

But a UK reserve fund does have an attractive intergenerational logic. It would allow the state to convert a temporary fiscal windfall into a permanent asset, with the returns used to reduce future pressure on taxpayers, workers and pensioners. It could also make the pension system less reliant on repeated political adjustments to the triple lock, the pension age or National Insurance. If created, such a fund should be managed independently, invested in a highly diversified manner, probably best globally, and with strict governance to avoid political interference. 

While the UK does have a National Insurance Fund that technically invests its surplus, it is obligated to invest that surplus almost entirely in gilts.^[30] This means that in practice, this money is lent to the government, at an interest rate near the Bank of England base rate, for general spending purposes. Repurposing any part of that money, therefore, would amount to raising the government’s borrowing requirement by that amount. In other words, the ‘surplus’ isn’t really a surplus, because it already is being used for something. If the money were diverted from gilts into equities, infrastructure or other higher-return assets, the government would need to borrow more elsewhere to replace it. This amounts to borrowing to invest.

Borrowing to invest is not automatically wrong. There are circumstances in which it can be justified. But it creates a demanding test: the fund must be expected to earn more than the government’s cost of borrowing, and by a sufficient margin to compensate for risk, volatility and political constraints.

That is a difficult test today. With gilt yields elevated, the return hurdle for a new UK fund is much higher than it would have been in the 2010s. If the Government can borrow at around 5%, and a conservatively managed long-term fund might be expected to earn around 6% nominally, the expected spread is thin. A one percentage point margin may not justify the risk of using scarce fiscal capacity to invest in markets rather than reduce borrowing, cut taxes or fund public services.

This is why sovereign wealth funds and public pension reserve funds have traditionally been thought most suitable for countries with budget surpluses, natural resource revenues or major one-off windfalls. For countries with persistent deficits, the policy can look less like saving and more like leveraged investment. In the words of Paul Goldsmith, New Zealand finance minister arguing that payments to New Zealand Super Fund, the country’s PPRF, should be suspended because the country cannot afford them: ‘If it was a slam dunk, we may as well borrow a half a trillion dollars and give it to the Super Fund. It’s not a slam dunk.’^[31] However, this has not stopped several countries with large deficits from establishing such funds in recent years, including Ireland and Canada.

A UK pension reserve fund would need to reach £300-£600 billion at maturity to deliver £15-£30 billion a year in drawdowns (roughly 10-20% of today’s State Pension cost). Working backwards from this with the sort of growth profile the model can produce – 6% annual return, 25 years of accumulation – implies a present-value seed somewhere around £80-£200 billion, or a smaller seed (£20-50 billion) plus very substantial annual contributions for more than 25 years.

There are a number of ways a government could find the money to create such a fund, including by using the National Insurance Fund surplus, though as discussed this is essentially funding through borrowing. Perhaps the least painless way for a nation to seed its reserve fund is through windfalls, such as might be generated via the selling of government assets such as land. This is what the Trump Administration says it intends to do for its proposed Sovereign Wealth Fund. Alternatively, the fund could be seeded through the levy of a new, hypothecated tax, though this would raise questions from the many voters who believe their National Insurance contributions are already going to fund their future retirement. 

It may be the case that the specific conditions the UK currently faces, not least surging gilt yields and a rapidly growing national debt, mean that there are simply too many opportunity costs to allow a reserve fund to be established. However, when conditions permit, or in the event of windfalls that could seed such a fund, it would be wise for the government to strongly consider establishing one.

3 Reforming Family Support

In this section, we propose three policies aimed specifically at making life better and easier for new parents, through changes to the tax, social security, and childcare systems. These policies are neither a ‘reward’ for people who have children nor a punishment for people who do not want to, or cannot, start a family. They recognise the fact that children, every single one of whom is important in their own right, are a contribution to our future national prosperity even as they are expensive to raise. In other words, because we all benefit when people choose to have children and so we all benefit when policy makes it easier for people to do so. 

This is particularly a matter of concern because the Total Fertility Rate in England and Wales is 1.39 In Scotland – due to start depopulating in less than a decade’s time – it is just 1.25, on par with famously low fertility Japan.^[32][33]

As fertility falls and life expectancy rises, the ratio of retired to working-age people increases. This places growing fiscal pressure on the working-age population, as a larger share of government revenue is required to fund healthcare, pensions, and social care for an ageing population. Core elements of Britain’s social infrastructure, including the NHS, were designed for a much younger society. Without demographic renewal, their long-term sustainability is in question. 

The immigration of working-age people mitigates an increasing old-age dependency ratio, more quickly but less durably than more children being born. But even after the very high levels of immigration the UK has experienced over the past decade, our old-age dependency ratio has continued to increase. With increasing political and democratic consensus that immigration to the UK must come down very sharply, we can expect the mitigating effect of working-age immigration to lessen over the coming years.

Low fertility also constrains economic growth. An older population absorbs more public spending, limiting investment and reducing disposable income through higher taxes. Over time, fewer births mean fewer workers and lower output. And because innovation depends on people, demographic decline ultimately weakens the ideas and dynamism on which growth depends: for there to be ideas, there must be human beings.

Taken together, it is vital that the British government does not remain neutral on whether or not people have children. Instead, policymakers must make life easier for British people to start, grow, and support their families. Furthermore, there is strong evidence that British people are having fewer children than they would like to have. 

While the British state already supports parents, through universal provision like education and targeted measures such as Child Benefit, children remain materially costly for individual families, even though they generate large social returns. The costs begin before birth: equipment such as prams, cots, and car seats is expensive, while caring for young children significantly reduces parents’ earning capacity. Mothers in particular are likely to take time out of the workforce in a child’s first year, and even with the aid of government-subsidised childcare provision, parents face constraints on working hours that persist well beyond infancy.

These pressures help explain why households with dependent children are much more likely to experience financial difficulty than those without. Survey evidence^[34] consistently shows that financial insecurity is a major factor deterring people from having children they want, whether that means postponing parenthood or deciding against another child.

Taken together, the policies proposed in this section focus on the period when children are youngest. The financial pressures associated with parenthood are not evenly distributed across childhood. They are heavily concentrated in the early years, when parents’ earning capacity is most constrained and childcare costs are highest. The reforms outlined below aim to rebalance support towards this phase of family life, reducing the upfront financial shock of having children while also making it easier for parents to remain in work.

3.1 Child Tax Allowance

One way to recognise the social value of raising children is through the tax system. While the government provides transfers to families through benefits and services, the structure of taxation itself remains almost entirely individualised. This means that the tax system does little to recognise that households raising children face higher costs while having lower effective earning capacity.

Should parents pay less tax? This paper argues that they should. Specifically, we propose that those who are raising young children should pay less income tax, making it easier for these parents to raise their young families. 

3.1.1 The problem: high burdens on new parents

Despite the extra costs borne by parents, especially when children are young, the British tax system takes no account of family responsibilities. Two adults earning the same income pay the same tax, even if one is supporting children and the other has no dependents. This ignores both the social value of children and parents’ reduced ability to pay tax. 

3.1.2 Our proposal

In recognising this reality, a Child Tax Allowance could ease the financial burden of raising children, making it easier for people to form and expand families in the first place. 

We propose a basic rate Child Tax Allowance of £10,000 per child aged under five, £20,000 per two children under five, and £30,000 per three or more children under five. This would effectively increase the amount that parents of children aged under five keep of what they earn. This Allowance would be worth up to: £2,000 for a household with one child aged under five; £4,000 for a household with two children aged under five; and £6,000 for households with three or more children aged under five. Because the relief of the Allowance would only be applied to basic rate income tax, the Allowance would function much like an increase of parents’ personal tax allowance. Parents or primary caregivers would be able to choose to split the Allowance between themselves or have it applied to one income only. We estimate this policy would cost £4.8 billion a year, assuming that every two-parent household opts to split the Allowance between them in a tax efficient manner.^[35]

These hypothetical case studies illustrate how the Allowance would work for families:

1. Nicola is the single mother of a four year-old boy. She earns £40,000 and pays the basic rate of income tax of 20% on her earned income above the personal tax allowance, which amounts to £27,430. That means her income tax bill is £5,486. But the Child Tax Allowance of £10,000 reduces the amount of income she has to pay income tax on to £10,000. That makes her tax bill £3,486 rather than £5,486. 
2. Adam and Amina have a daughter aged three and twin boys aged one. Amina is working part-time and earns less than the personal tax allowance Adam earns £60,000 and so pays income tax on £47,430, amounting to £9,486. Because Amina’s earnings are currently low, the couple decide Adam should claim the entire £30,000 Child Tax Allowance the family is entitled to. The Allowance means that Adam’s income tax bill decreases from £9,486 to £3,486. 
3. Sarah and Ben have three daughters all aged under five. Their household is entitled to a £30,000 Child Tax Allowance. Ben earns £35,000 and Sarah earns £28,000. If either of them were to claim all the Allowance, they would miss out on some of the £6,000 they could save in tax because neither of them is independently earning enough to make full use of it. They split the Allowance in half between them, so that each removes £3,000 off each of their tax bills. Now, Ben pays just £1,486 in income tax and Sarah just £86. 

It is important to note that the splitting element of our Child Tax Allowance policy would currently be very complicated for HMRC to administer, because it lacks data on families. A version of the policy that applies it only to one parent’s income would be significantly easier to administer with data the government currently has access to, and would also be cheaper. However, it would also mean more eligible parents keeping less of their earned income.  

3.2 Compensating Informal Childcare 

Reducing the tax burden on parents addresses one dimension of the cost of raising children. But financial transfers alone cannot resolve the practical constraints that many parents face when attempting to combine work and family life. In particular, access to reliable childcare remains one of the most significant barriers preventing parents from returning to work or increasing their working hours. Addressing this constraint requires reforms not only to financial support, but also to the childcare system itself.

Parents in England face restricted access to childcare in terms of both cost and availability. The government’s free childcare offer expanded in September 2025 but there has not been the necessary increase in spaces to be able to accommodate the ensuing increased demand, especially as shortages existed before the expansion. At the same time, there is a long-running decline in the number of childminders in the UK. Difficulties finding the right childcare makes it more difficult for the parents of young children, especially mothers, to work or increase their hours. Yet, the government does very little to encourage another, very popular type of care: the informal care provided by trusted relatives like grandparents. 

3.2.1 The problem: A shortage of childcare places

Under the government’s current free childcare offer,^[36] working parents with a child aged between nine months and five years old are entitled to 15 free hours of childcare a week during school term time. The parents of all three to four year olds are entitled to 15 hours of free childcare a week and working parents to 30 hours a week during school term time. As of September 2025, the government’s free childcare offer increased in generosity: now, 30 hours of free childcare a week is available for eligible working parents with a child from nine months old up to school age, during school term times. 

But in 2024, before the offer expanded in generosity, less than half of English local authorities reported^[37] having enough childcare places to meet the entitlement. Only 45% said they had sufficient provision to meet the current 15 hour entitlement for two year olds, and 62% said they had enough provision to cover the 15 hour entitlement for three and four year olds. Between December 2024 and December 2025, the number of registered childcare places in England increased by only 15,800, a far cry from the 85,000 new places that the Department for Education estimated would be necessary by September 2025.^[38][39]

A contributing factor to the anaemic increase in places is the sharp decline in the number of childminders. Between 2013 and 2023, the number of childminders in England declined^[40] by over 50%. Between 2024 and 2025, over a thousand childminders left the sector.^[41] The decline in childminders also means available formal childcare has become less flexible, as childminders are often able to be more flexible and offer services like wraparound care. 

For parents, England’s childcare shortage places means long waiting lists^[42] for places and long journeys to settings that do have availability. Government analysis finds that access to childcare has declined overall in England since 2020, but that the decline is regionally concentrated^[43], with the North East, the East Midlands and Yorkshire and The Humber seeing the largest proportional decrease in their childcare access over this period. However, there is also evidence that parents in London are more likely to struggle to access childcare, with 65%^[44] of mothers in London with a child aged under ten struggling to find childcare, compared to 54% across the UK.

This matters because access to childcare is a key factor affecting the ability of parents to work: more people enter the workforce where access to childcare improves. 2023 analysis^[45] found that the government’s introduction of 30 hours a week of free childcare for all working parents of three and four year olds led to around 286,000 more people in employment a year on and an increase of £22.3 billion in Gross Value Added. Equally, poor access to childcare has negative labour supply effects and England’s childcare shortage is making it more difficult for the parents of young children to work or increase their hours. 

In England, there is a significant cohort of parents of young children who would prefer to work if they had access to the right childcare. In 2023, 54% of non-working mothers with children aged 0 to 4 said^[46] that if they could arrange good quality childcare that was convenient, reliable and affordable, they would prefer to go out to work. 

But this effect is not felt equally between parents, with mothers more likely than fathers to struggle to return to work or increase their hours where there are difficulties finding childcare. Mothers themselves clearly identify this difficulty as making it harder to work. 2023 polling^[47] of UK mothers with at least one child aged under ten found that 46% of those who reported struggling to find childcare said this challenge had prevented them from working more hours. 29% said they had reduced their working hours as a result of struggling to find care. 

Expanding formal childcare provision is one response to this challenge, but it is not the only one. A large share of childcare in Britain already takes place outside formal settings, provided by relatives and trusted adults. Yet this informal care receives almost no recognition in public policy, despite playing a crucial role in enabling parents to work.

Currently the only government scheme to incentivise and support informal care allows grandparents providing childcare to working parents to claim National Insurance credits in order to help fill gaps in their National Insurance record. The scheme^[48] is restrictive and uptake is low^[49]: credits are only available to grandparents under state pension age and the value of the scheme is limited to £6,000 over the entire course of retirement. There is zero government support for the informal childcare provided by other trusted adults, such as aunts and cousins.

But the informal care provided by grandparents and other close relatives is an important form of childcare that helps parents, especially mothers, go out to work. In England in 2023, 48%^[50] of working mothers with pre-school children identified having relatives who can help with childcare as a factor that helps them to work. Grandparents are the key providers of this informal care – 28% of grandmothers and 16% of grandfathers report^[51] caring for their grandchildren, at an average of just over eight hours a week.

Beyond the reports of young mothers, evidence does show that access to grandparental childcare helps mothers work. Cross-country European research shows^[52] that when grandparents care for young children they increase the likelihood that the mother of those children works by 13 percentage points, and that the effect is most significant for mothers of pre-school children.

But even as the number of young mothers returning to work has increased over the past few decades, the average hours of childcare provided by grandparents and the proportion of grandparents providing such care has not increased^[53]. There have been no policy attempts to encourage more grandparents to provide more childcare.

3.2.2 Our proposal

Rather than relying exclusively on the expansion of formal childcare provision, government policy should also recognise, support and incentivise the informal childcare that already underpins the childcare system. By allowing parents to allocate part of their childcare entitlement to trusted caregivers such as grandparents, the state could expand the effective supply of childcare quickly and at relatively low cost.

We propose that working parents should be able to use their free childcare entitlement to compensate the informal childcare provided by trusted adults like grandparents, which would require an amendment to the Childcare Act 2016.

To be eligible for this expansion in the scope of the free childcare entitlement, parents would need to meet the work and minimum earnings requirements of the 30 free hours childcare entitlement. This would mean that both parents must be in work, and earning on average the equivalent of 26 hours a week at the national minimum or living wage. However, parents should not lose eligibility if their income exceeds £100,000 – this is in order to protect incentives to work and maximise the labour supply effects of the policy change.

To make use of this policy change, parents would continue to apply online to register for the entitlement but will also be able to allocate some or all of their 30 hours to their named trusted adult. Parents would need to apply with: the name and address of the trusted adult and their relationship to them; and an enhanced DBS check with barred lists for the trusted adult.

We anticipate that the vast majority of trusted adults would be grandparents or other close relatives. The hourly compensation rate provided by the government would reflect that this informal care is not equivalent to that offered by EYFS-qualified nursery staff and childminders and so will be set at a rate lower than that awarded to nurseries and childminders, initially at £5 an hour. To protect high standards of care and reduce the chance of fraud, no one trusted adult will be able to be registered as and receive compensation for caring for more than four children.

The compensation should be delivered via a tax credit for parents, who can then pass the compensation on to the trusted adult. For employed parents, the tax credit would be administered via PAYE, so that trusted adults may be compensated on a monthly basis. Self-employed parents would need to claim the tax credit via their yearly self-assessment. The named trusted adult should themselves receive regular email communications informing them when the compensation has been issued to parents and how much has been issued. 

This policy change would enable more grandparents to care for their grandchildren, and to do so for more hours, by recognising the value of the childcare that they do and contributing to costs^[54] incurred in providing this care. This policy can also encourage other trusted adults, such as aunts, uncles, cousins and close family friends, to increase the childcare support they give to parents now.

Encouraging the highly flexible care that grandparents and other trusted adults can provide would help to ameliorate England’s childcare shortage. This policy can also achieve these goals at a lower cost to the Treasury than purely subsidising the formal care provided by nurseries and childminders. This is because the care provided by grandparents and other such trusted adults is informal and not equivalent to that offered by qualified nursery staff and childminders. To reflect that, the hourly compensation rate should be below that awarded to formal settings.

Compensating grandparents for childcare can help address the childcare shortage by enabling more grandparents to care for their grandchildren, for more hours, and at a lower cost to the government than the formal care provided by nurseries and childminders.

The economic impact of this policy will be multifaceted. The main objective of the tax credit is to incentivise grandparents or other trusted caregivers to provide additional childcare. But from an economic standpoint, this could have effects through three different channels.

1. Providing additional informal childcare: the tax credit would incentivise parents to arrange additional informal care with trusted caregivers, increasing the provision of informal childcare and freeing them up to take on more hours at work or get back into employment. This effect is likely to be particularly pronounced among parents who are: starting from a low base of childcare provision; looking to increase their working hours; and struggling to find formal childcare places. Some of these parents might then begin to use their childcare entitlement. Although any parents entering the childcare system in this way would produce a fiscal cost, this could produce positive labour supply effects. 
2. Subsidising informal childcare that would have taken place already: there will be an extent to which the tax credit subsidises informal childcare that would have taken place anyway – for example, grandparents that were already willing and able to provide 5 hours of childcare a week. While there is a moral argument for recognising this contribution, from an economic standpoint this is a deadweight loss: using resources (in this case, taxpayer money) to subsidise actions that would have happened anyway, without providing any additional benefit. 
3. Substituting formal childcare for informal childcare: a third possibility is that parents who are already using the free childcare allowance reallocate some of this allowance from formal childcare to informal childcare. While this would not provide additional childcare, since childcare is simply being shifted to a different form, it would – because informal caregivers would be compensated at a lower rate than formal providers – represent a fiscal saving for the government.  

3.4 Frontloading child benefit

The reforms discussed so far focus on reducing the tax burden on parents and improving access to childcare. But the structure of direct financial support for families also matters. In particular, the timing of government support can influence family formation decisions and the financial pressures experienced by parents when children are youngest.

Child Benefit is a means-tested payment that sees eligible parents receive payments every four weeks, per child. Even after 2010 reforms that have limited eligibility, Child Benefit is an expensive and generous benefit. But changes to how and when Child Benefit is received by families could transform its impact and value to parents.

3.4.1 The problem

Child Benefit can only be claimed by one parent and is currently worth £26.05 a week for an eldest child and £17.25 a week for an unlimited number of further children, paid out on a monthly basis. A parent can claim Child Benefit until their child is 16, and until 18 if they stay in full-time education. Child Benefit has been means-tested since 2010, through the High Income Child Benefit Charge (HICBC). The form taken by HICBC today means that if anyone in a child’s household earns above £60,000, Child Benefit payments begin to be tapered away, diminishing to zero once anyone in the household is earning £80,000 or more. Onward has previously called for the abolition of HICBC, which contributes to severe effective marginal tax rates for many families.^[55]

Child Benefit is expensive, costing the government £13 billion a year, and it is worth a lot to parents. For an eldest child who stays in education until they are eighteen, a household can expect to receive over £24,000 in payments in total, and a little over £16,000 for a second child. That is a significant sum of money, but spread out over a long period of time. That is despite the fact that children are particularly expensive to their parents when they are pre-school age, because the care they require impedes their parents’ ability to work and because of the cost of childcare.

The amount of financial support that new parents receive is particularly important to helping them realise their desired number of children. Personal financial outlook and stability is a key factor that influences when and how many children parents and prospective parents choose to have. That means that support given around the time that these decisions are being made, particularly the decision to have a second or third child, is disproportionately effective in helping parents to decide to have wanted children.

3.4.2 Our proposal: front-loading Child Benefit

In addition to giving Child Benefit payments piecemeal over a sixteen or eighteen year period, the government should also allow eligible parents to opt into a new system that will see them receive a smaller amount of money but concentrated over the much shorter period before their child starts school.

We propose that, as an alternative to receiving £26.05 a week for an eldest child and £17.25 for any subsequent child, parents opting for the new system instead receive £57.60 per week for all children aged under five. Overall, this will mean that these parents receive £12,000 in Child Benefit payments for each of their children, at a time in life when their children are particularly expensive to them. 

Chart 4: Child Benefit reform – proposed savings by family size

The government would also save money for every parent who chose to take up this new system. As the chart above shows, the government would save over £12,000 for every oldest child whose parents opt into the new system, and a little over £4,000 for any second and subsequent children who choose the new system. 

This hypothetical case study illustrates how the new system could help young families. 

George and Angela live in north London with their daughter, Millie, aged two. George works full time and Angela works four days a week. Millie goes to nursery four days a week, from 8am to 6pm. As eligible working parents, George and Angela benefit from 30 hours a week of government-funded childcare. But they actually use 40 hours a week and the 30 free hours only apply to 38 weeks of the year, during school term time. To cover those extra hours, they pay for 10 hours on top of the funded entitlement and for the full 40 hours for 12 weeks of the year. That means that despite subsidised childcare, George and Angela spend £796 a month on childcare, or £9,552 a year.^[56]

George and Angela opted into the new Child Benefit system when Millie was born and will receive £3,000 a year in Child Benefit until Millie starts school. This money has been very helpful in making their childcare bill more affordable and helped Angela to decide that it was worth her while to return to work. Initially, she was not sure it would be as she only takes home £13,944 post tax from her salary of £30,000, and nursery fees take up 68% of that. And during the first year of Millie’s life, the family found the extra Child Benefit very helpful in meeting household expenses while Angela was only receiving Statutory Maternity Pay. 

The couple are aware that receiving the enhanced level of Child Benefit means they will not be eligible for any Child Benefit at all once Millie is aged five. But they are not concerned about that because the extra money is so helpful in meeting childcare costs which they know will not be an issue once Millie starts school. 

It should be clearly stated that though this reform would indeed save the government money over time, it would have implications for the government’s near-term financing requirements, because Child Benefit expenditure is being brought forward. This higher upfront spending is likely to raise gilt yields, thus putting up the cost of government borrowing. This is a real risk and should be mitigated by proposing this policy alongside cost-saving measures, including those proposed in Chapter 3 but also potentially wider reforms to the benefit system. 

4 Conclusion

This report has argued that pension reform and family support should be understood together as part of the same agenda. The common principles that underpin that the proposals are reciprocity and sustainability.

The pension reforms this paper proposes seek to protect pensioners from inflation and ensure they share in rising living standards, while reflecting real demographic pressures. Increases to the State Pension age would become significantly less politically fraught and more predictable, allowing people to plan. And the poorest pensioners would be protected in a targeted way through a strengthened Pension Credit system rather than through an expensive universal Triple Lock. When fiscal conditions allow, a pension reserve fund could help future governments smooth the costs of ageing across generations and further stabilise the State Pension system. 

But Britain must also make it easier for people to start and raise families. The policies proposed in this report are deliberately focused on the early years, when the financial shock of parenthood is greatest and parents’ earning capacity is most constrained. A Child Tax Allowance would recognise that parents of young children have a lower ability to pay tax than otherwise similar households without dependents. Compensating informal childcare would make better use of the trusted care already provided by grandparents and other relatives, while helping parents return to work or increase their hours. Frontloading Child Benefit would give families more help when children are young, without necessarily increasing the lifetime cost of support.

The aim is not austerity for the old or unlimited subsidy for the young. Moving from Triple Lock to family support must mean reform that is honest about our fiscal future if politicians fail to act to solve the unaffordability of our current pension system or face the challenge of the demographic pressures we are already experiencing.

^[11] This is a mechanical stress test, not an alternative OBR forecast. The OBR’s central projection has State Pension spending reaching 7.7% of GDP in the early 2070s, with around 2.7 adults below State Pension age per pensioner. The ONS’s 2024-based old age structure variant projects that, by 2073, the UK will have 35.7 million working-age people and 19.3 million pension-age people, equivalent to 1.85 working-age adults per pension-age person. Holding the OBR’s assumptions about pension generosity, earnings, employment, productivity, GDP and policy constant, the State Pension cost is scaled by the deterioration in the support ratio: 7.7 × (2.7 / 1.85) = 11.2% of GDP. Since the current State Pension bill of £138 billion is around 5% of GDP, 1% of GDP is approximately £27.6 billion; 11.2% of GDP therefore implies a bill of roughly £310 billion in today’s money. The exercise is intended only to illustrate the sensitivity of a pay-as-you-go pension system to adverse demographics.

The post From Triple Lock to Family Support appeared first on Onward.

Achieving change is very difficult when it imposes concentrated costs on a group of people who have the power and motivation to resist it. 

When the Meiji Government came to power in 1868, they wanted to turn Japan into a centralised, industrialised, and fiscally modern state that could hold its own with the great powers of the West. One of the many problems they faced were the samurai, who received expensive and hereditary stipends that constituted over a third of government expenditure. The samurai strongly opposed the ending of these stipends, which were their primary income, a resistance which had teeth because of their monopoly on violence as the traditional warrior class. Instead of going to war with the samurai, the Japanese Government bought them out by replacing these stipends with government bonds, thus avoiding mass expropriation and an ensuing civil war, and turning their expensive liabilities into a manageable public debt. 

The lesson of the Meiji Government’s approach is that making these highly affected groups the key beneficiaries of a change can make that change possible. That is how land readjustment, a mechanism that allows fragmented land to be pooled, re-planned and re-plotted, works. Land readjustment attempts to reward those who are most supported by a proposed development – those whose land a scheme involves – by sharing the resulting value uplift of that development with them. 

The system of land readjustment, as proposed by this report, flows from the twin principles of consent and mutual benefit, aiming to give those who stand to lose the most from a development good reasons to support it. It is also a proposal that seeks to treat those who might oppose a development as rational people with real concerns who can be negotiated with. 

This timely exploration of the principles of land readjustment is essential reading for policymakers considering the challenge Britain faces in delivering the homes and infrastructure it needs.

– Lord Banner KC

Executive summary

This paper proposes the introduction of land readjustment to the UK, a land assembly mechanism in use in many other countries. The UK currently relies on two other tools to deal with the challenges of assembling land for development: negotiated sales and compulsory purchase. But both of these have their drawbacks as well as advantages. 

Negotiated sales are by nature fragile. A single holdout landowner in a key location, without which the development cannot proceed, can collapse a scheme by demanding a disproportionately high price or simply by refusing to sell. Compulsory purchase, while sometimes indispensable, is slow and legally fractious. As a form of expropriation, it must also be used sparingly. Land readjustment can be integrated into our system as a third way between these two tools, less fragile than negotiated sales and more democratic than compulsory purchase. 

Land readjustment means that multiple owners, working with a developer, can pool their plots so that their land is developed as a whole. After development, that land is redistributed back to owners in smaller but more valuable plots. These plots are smaller because some land is retained by the developer to sell as a profit and because some is necessary for new infrastructure, like parks or a new road system. To go ahead in the first place, a land readjustment scheme must have the support of a supermajority of landowners who own a supermajority of the land in question. 

In this paper, we demonstrate how a land readjustment scheme might unfold in the UK using the example of Park Royal, an excellently located industrial area in London. And we give further insight into how land readjustment is already at work in other jurisdictions with examples from Japan and Spain.

Introduction

Land is often divided into a jigsaw of small, irregular plots, each with its own owner. This fragmentation poses a major obstacle to development and existing tools to pool such land and permit development on it are inadequate. Projects are particularly susceptible to collapse by a small number of holdout landowners.

This paper describes the issue posed by fragmented land and outlines how land readjustment, a globally tried and tested urban planning tool, can help develop such land in the UK. Land readjustment allows multiple owners to pool their plots so that land can be redeveloped as a whole, before being redistributed back to owners in smaller but more valuable plots. There are two key principles at the heart of land readjustment and of the version this paper proposes. First, is that a large majority of the affected rights-holders, be they freeholders or leaseholders, must support the development. Second, the value created by that development is fairly shared back to those rights-holders.

As one walks through the English countryside, like the stretch of Cornish coast above, one crosses field boundaries that squiggle and snake. Thin strips of land sit alongside squat rectangles with bulging sides. One field here curves while its neighbour fans out like a skirt. This patchwork is the result of the piecemeal clearance of heath and woodland by neolithic and medieval farmsteads, of the solidifying process of enclosure, and myriad other events from the parcelling out of land between siblings to the selling off of strips to raise dowries or pay debts. 

Similar fragmentation characterises many significantly more built up areas. Fragmented and yet underdeveloped land is particularly common in former industrial areas – for example where streets and plots have evolved around long-vanished rail lines, depots and estates – and at the suburban fringes of cities. 

The complexity of these often well-located pieces of land now constrains development. Redeveloping these areas requires assembling numerous owners, coordinating the construction of infrastructure, and negotiating with landlords who are prepared to hold out indefinitely for a better deal. 

We have been in this situation before. The legacy left to us by the open field system, a medieval feudal farming system, was highly fragmented land burdened with a complex web of rights and ownership. The end of the open field system in England was achieved by what is easily recognisable as a type of land readjustment. This was crucial in unlocking land for more productive uses as the Industrial Revolution was beginning. In fact, in the eighteenth and nineteenth century, Parliament was extremely active in using its powers to assemble land for development. Every major railway was authorised by its own Act and given the power to assemble the land it needed and turnpike trusts and canal companies were given statutory powers to purchase land and to organise new infrastructure.¹ 

To address the challenges of fragmented land today, this paper sets out: how land readjustment works and our history of it; how modern land readjustment works in other countries; and how a revived UK version could unlock development in what are now highly challenging sites.

The challenge of fragmented land

To understand the challenge that land with fragmented ownership poses to development, consider the example of London’s Park Royal, pictured below. Though in easy reach of stations on the Piccadilly and Central lines, it consists mainly of warehouses, with an incoherent road pattern that is the legacy of attempts to accommodate now defunct rail lines and depots. Park Royal is a very valuable piece of land. A great number of homes could be built there, helping to ease London’s acute housing shortage. If the sections of Park Royal within a ten minute walk to a tube or train station alone were developed to Paris-level densities (400 dwellings per hectare), then 135,000 new homes could be built.² But to accomplish that, a would-be developer would need to consolidate Park Royal.

The alternative, redeveloping just one plot in the area, is much less desirable, both to developers and planning authorities. This is not only for reasons of fixed costs, economies of scale, and viability, but also because of infrastructure and access for the small strip of homes that might be fitted onto a single plot as it exists now.

Consider also that some vital pieces of infrastructure require odd bits of land to be assembled. To build a new road through Park Royal, connecting it better to other parts of London, a long thin piece of land must be acquired that will doubtless cut through the existing properties and land of many different owners. A similar problem is presented by other major bits of infrastructure that must be built.

Existing tools are inadequate

To assemble the land, the would-be developer of Park Royal has two options available: negotiated sales and compulsory purchase.

Negotiated sales

Negotiated sales mean that a developer – or a public body, if the development is being coordinated by a development corporation or a council –  must negotiate a deal with each landowner separately. If the pictured area of Park Royal was to be redeveloped, it would require the developer to successfully: establish who the owner is of every single bit of land; make contact with that person or entity; and persuade that owner to sell them that land for a price that is not so high that it makes the entire development project economically unviable.

Negotiating sales on an individual basis in an area like Park Royal, where there may very easily be over forty owners, will take a long time. But it also means that a small number of holdout landowners – and in some cases just one –  can collapse an entire project. For example, a landowner who owns a large warehouse in a crucial central part of a development may refuse to sell. Or a small group of landowners in certain key areas within a proposed development, knowing their land is key to that development’s viability, may hold out for so high a sale price that a developer cannot buy them off without making the venture unprofitable for themselves.

Compulsory purchase

This brings us to compulsory purchase, which is currently the UK’s primary planning tool to deal with holdout landlords in developments of regional or national significance. A Compulsory Purchase Order (CPO) allows certain public bodies (such as local authorities and government departments) and some private companies with statutory powers that run essential infrastructure (like airports) to purchase land without the consent of the owner, when it is in the public interest to do so. A high profile recent use of compulsory purchase is in order to secure the land necessary to build HS2.  

Compulsory purchase is expropriation and there are a number of safeguards upon it. For a CPO to be compatible with the right to property under Article 1 of Protocol 1 of the European Convention on Human Rights, as applied to UK law by the Human Rights Act, it must meet a legitimate public interest test and strike a fair balance between that public interest and the rights of affected property owners. Government guidance on that public interest test specifies that local authorities must show a “compelling case in the public interest”. CPOs must also be approved by the government via the relevant Secretary of State. The affected owners must be compensated so that they are not financially worse off than if their property had not been compulsorily purchased. Finally, the affected owners are able to object and have the proposed CPO independently adjudicated. 

Even with these safeguards in place, compulsory purchase remains a way for the government to legally violate private property rights in the aid of what it judges to be the greater good. As a result, it is unpopular and should be used sparingly. Furthermore, the Government’s Planning and Infrastructure Bill will remove the safeguard that a local authority’s CPO must be approved by a Secretary of State.

Councils must often turn to compulsory purchase to assemble land in complicated multiowner brownfield sites. But for most local authorities, the process is very slow and extremely resource-intensive. The challenges of fragmented ownership, title constraints, viability tests, hope-value compensation and legal risk mean that CPO is treated as a last resort. There is a mismatch here: being able to assemble fragmented land for development is very valuable, but the power that is supposed to allow it to happen where there is a compelling public interest is excruciatingly difficult.

Our proposal: land readjustment

What is land readjustment?

Land readjustment is a legal mechanism that allows the various owners of a fragmented area of land to pool that land so that it can be developed as one. Currently, valuable areas on suburban fringes or in complex urban areas like Park Royal can be very challenging to develop because of fragmented ownership. Land readjustment, an urban planning tool that has been in use in countries all over the world for decades, offers a third way to realise such developments.

England’s history of land readjustment

“Common field arable usually lies, respecting the lots of individuals, in so scattered and divided a state, that every operation of tillage, harvest…is carried on at an expense considerably greater than in enclosures…” – Arthur Young, General Report on Enclosure (1808)

England previously developed a highly successful version of land readjustment in response to difficulties not unlike those we face with fragmented land today. Well into the nineteenth century, parts of rural England were owned and worked under the medieval manorial open-field and common-rights system, affected by a tangled burden of rights and duties that impeded development.

In terms of arable land, this meant fields that were physically divided into small strips. A field might be owned by a single freeholder but parcelled out into strips, each farmed by a copyholder with the customary right to work that land. Or, a single field might comprise strips owned by and farmed by various freeholders, with some strips leased out, and others farmed by copyholders though still owned by a freeholder. Similarly, pasture land was often grazed under the ‘stint’ system.³ A stint provided how many animals a local freeholder could graze on the piece of land in question and was generally attached to a particular tenement and were heritable. In some parts of England, stints or fractions of stints could be sold or traded separately.

This system could be inflexible and acted as a restraint on economic development. A stint-holder could not unilaterally put the land their animals grazed on to different and more productive uses without the consent of others who also held stints over the same piece of land. Scattered arable strips also impeded development and change of use, as any reorganisation required numerous small rights-holders to come together and agree. 

Efforts to reorganise such land, known as enclosure, were often carried out informally by local agreement. But after the Glorious Revolution of 1688, Parliament became significantly more active and so took on a much greater role in this process of land reorganisation.⁴ From the late seventeenth century, freeholders and small rights-holders began to respond to the problem of land with severely fragmented ownership by coming together to petition Parliament to reorganise the rights to specific pieces of land. As with modern land readjustment, a petition to reorganise a piece of fragmented land required the consent of a supermajority of the affected landowners to succeed, with a necessary threshold of somewhere between 75% to 80% of landowners by value.⁵ 

If successful in their petition, Parliament would pass a private Act permitting the reorganisation and development of the land and appointing commissioners to oversee it. The commissioners were charged with surveying the land in question to clearly establish who had what rights over it, deciding how the consolidated land should be thus shared out, and developing new infrastructure like drains or roads.⁶ 

The General Inclosure Act of 1801 standardised much of the content of these private Acts, but it remained the case that every enclosure required its own private Act of Parliament. The General Inclosure Act of 1836 made it possible to enclose land without a private Act, as long as two-thirds of affected landowners both in number and land value consented.⁷ Under the Inclosure Act 1845, the enclosure process was streamlined further and individual private Acts were replaced with Provisional Orders that were confirmed by Parliament in bulk. 

In this way, Parliament was able to dissolve the impediments of the common field system on demand from those it directly hindered, reorganising the rights over that land and giving individuals new rights over particular bits of land. This process of land readjustment was an “essential prelude to the Industrial Revolution”.⁸ It meant that commonly held agricultural land could be turned to new uses with new infrastructure, with housing and industry springing up where before only grazing or farming had been permitted.⁹ The difference even in agricultural terms between enclosed and open field land was highly observable. In an 1808 report for the General Board of Agriculture, agricultural economist Arthur Young wrote that the parish of Childersley, despite sharing “perfectly similar soil” with the neighbouring parish of Hardwicke, was significantly more productive than Hardwicke in terms of wheat, barley, oats and beans.¹⁰ 

Just like the modern land readjustment that takes place all over the world, this organically developed system was a way of consolidating highly fragmented land and allowing it to be put to more productive uses. Just like modern land readjustment, it required the support of a supermajority of the landowners affected to take place. And again just like modern land readjustment, it compensated those with a prior interest in the land by giving them new plots. 

How could land readjustment work in the UK today?

Section 5 explains how land readjustment works in two case study countries, Japan and Spain. But first, it is helpful to summarise step by step how the land readjustment works in general, which we illustrate with the example of Park Royal.

Park Royal and land readjustment: a hypothetical case study

The Mayor of London, looking for ways to densify and make better use of land in the city, asks Ealing Council to look into developing Park Royal. The various owners of Park Royal each possess only a small piece of land in the area, perhaps a warehouse or two, situated on a higgledy-piggledy road network. 

Ealing Council knows that Park Royal could be much more productively used than it is now. Land could be assembled to permit the development of a data centre, or the area might instead host new homes, within easy walk of the local tube station. But Ealing’s assessment is that the process of development would be slow and uncertain (using negotiated sales) or slow, controversial and legally fraught (using CPOs).  

Many of the Park Royal landowners themselves know that their land has great development potential. But they face a collective action problem. Each of their respective bits of land are near other warehouses, just as unsightly as their own. It makes little sense to attempt to develop their small, oddly shaped parcel of land with homes, right in the middle of an industrial estate. No developer approaches them with such a proposition. 

A new way forward emerges when land readjustment is introduced into the UK.

1. An area is designated and approved as a candidate for land readjustment. For an area to be eligible for land readjustment, it must be proposed as such by the local council and then approved by the Secretary of State for Housing, Communities and Local Government. Ealing Council proposes Park Royal be designated and it is approved for land readjustment by the Secretary of State.
2. A land readjustment scheme is drawn up. A developing agent, which can be a private or a public entity, is appointed by Ealing Council. The agent draws up a land readjustment scheme for Park Royal. The scheme proposes replotting the land, giving it a new road network, and developing it with homes or perhaps new infrastructure. If homes are proposed, the plan is likely to include amenities such as parks. 
3. That scheme is voted on by the affected landowners and can only go ahead if approved on a supermajority basis. This proposal is put to Park Royal’s landowners in a ballot. The scheme will only happen if a supermajority of landowners owning a supermajority of the land vote in favour of it. This democratic system prevents a large number of small landowners forcing a landowner with a large amount of land to develop. A minority of Park Royal landowners strongly oppose the scheme and do vote against it, but ultimately a supermajority of landowners who own most of the land vote in favour and so the scheme is approved.
4. The scheme receives planning permission. The developing agent submits an application for planning permission to Ealing council and an environmental impact assessment if required.  Approval from the Building Safety Regulator, if applicable, is also sought.
5. The approved area is redeveloped. The agent redevelops Park Royal. This includes knocking down existing warehouses and buildings to impose a coherent new road pattern and to create regular plots. The development will include the improvement of the area’s infrastructure in line with the approved plan.
6. The plots are shared back out to landowners but a percentage is retained by the developer. Now that the development is complete, the new plots are shared out to Park Royal landowners in proportion to what each contributed to the scheme. The Valuation Office Agency, which already exists and specialises in property valuation, assists in making sure that the plan gives owners back plots that are proportionate to what the land they contributed to the scheme. The plot of land each landowner receives is not necessarily in the same area where they had owned land before, and is also smaller than that they had because of space taken up by new infrastructure and because a portion is retained by developing agent to sell and so make a profit on the scheme. Yet though smaller, these new plots are much more valuable to the landowners. This is because, regularly shaped and now located with new and improved infrastructure nearby, they are ideal to be sold on for further development.
7. Landowners are now likely to sell their land on. The landowners are now likely to sell their plots, thereby realising the value uplift that their supermajority vote facilitated.

A third way between negotiated sales and compulsory purchase

Land readjustment sits between negotiated sales and compulsory purchase as a third way planning tool, more democratic and less intrusive than compulsory purchase and yet more efficient and less fragile than negotiated sales. Currently, the development of a fragmented area of land can be stymied by a small number of holdout landlords who, by refusing to support development, can collapse a whole project, even when the majority of landlords are in favour of it. Faster than individual negotiated sales, land readjustment allows landowners to negotiate and realise value uplift as a bloc. No single landowner can act as a veto player because if a supermajority of landowners who own a supermajority of the affected land support a scheme, it can go ahead.

But even under this system, a holdout landowner who votes against a land readjustment scheme but is overruled by the supermajority will be better off than if a CPO had been deployed against him. If his land had been compulsorily purchased, the holdout landowner would only have received cash compensation equivalent to his land’s market value. But because his land is part of a land readjustment scheme, the holdout landowner not only receives back a physical asset at the end of the development, he receives one that is worth more than what it was previously. This is reflective of how land readjustment allows urban planners to share the value uplist of development with those it asks most of, giving those people an incentive to cooperate in the creation of better amenities for all. These key differences between land readjustment and expropriative tools like compulsory purchase mean that land readjustment projects are much less likely to be held up by legal challenges, for example by challenges under Protocol 1, Article 1 of the ECHR.

Further positive data is provided by estate regeneration, to some extent a relative of land readjustment that is already working well in the UK. Estate regeneration concerns the development of low density post-war social housing in high-value areas like London. Under a regeneration scheme, an estate is re-developed only on the basis of a ballot of residents. If a proposed regeneration scheme wins the supermajority support of the residents, it goes ahead. In return for supporting the development, residents receive a new and much improved home and the developer is even able to add new social housing to the estate.¹¹ Developers are motivated to offer to undertake these schemes because the regeneration creates additional homes that they can sell at a profit. Between 2018 and 2024 alone, residents have voted in favour of forty estate regeneration schemes in London, demonstrating the willingness of tenants to support a scheme that allows them to share in the benefits created by development.¹² 

International case studies

Japan

In 1923, three strong earthquakes hit Tokyo in the span of around seven minutes. More than half of the city was destroyed and tens of thousands of people were killed in the quakes and the fires that followed. Land readjustment, which had already been used in Japan to consolidate farm land, was deployed on a large-scale to rebuild Tokyo. After the Second World War, it was again much used to rebuild Japan’s cities and in 1954 the government passed the Land Readjustment Act, systemising how land readjustment worked across the country. In addition to post-disaster rebuilding, Japan has also used land readjustment to develop new towns, regenerate urban districts, and build important infrastructure like railway stations.¹³ As of 2003, land readjustment has been used to develop roughly a third of Japan’s entire urban area.¹⁴

Step by step, this is how land readjustment works in Japan¹⁵:

1. An area is designated for land readjustment by a municipality or prefecture. This authorises the area for land readjustment but does not compel it.
2. A body is created to deliver the land readjustment project. The 1954 Act allows for several different types of delivery bodies to be created or brought into to manage the project:
   • A Land Readjustment Association, formed voluntarily by landowners and leaseholders. This is the most common delivery body;
   • The municipality or prefecture, often used for post-disaster reconstruction or new-town development;
   • A private corporation, authorised by the prefectural governor where public or association methods are impractical;
   • The Urban Renaissance Agency, for complex or multi-jurisdictional urban projects.
3. If the land readjustment project is government-led (by the Urban Renaissance Agency, the prefecture or the municipality) then it can proceed without the affected owners and leaseholders’ consent to the project. However, in practice, projects do not go ahead against substantial opposition. If the project is led by a Land Readjustment Association – as most are – then a proposed scheme must have the support of at least two-thirds of the affected landowners and two-thirds of the affected leaseholders, each representing at least two-thirds of the affected land area, in order to go ahead.
4. The delivery body creates a project plan, outlining how land parcels will be reorganised, how much land will be contributed for public use, and how costs will be financed through the sale of reserve land. The plan must be approved by the prefectural governor, unless the project is being delivered by the Urban Renaissance Agency in which case the Minister of Land, Infrastructure, Transport and Tourism must approve it.
5. The area is redeveloped according to the plan.
6. The replotted land is shared back out to landowners, each of whom ends up with a smaller but more valuable plot than what they owned previously. Where necessary, cash equalisation payments to a landowner can be used to correct discrepancies in the value of their new land in comparison to the old. The only land not shared back to landowners is that which now hosts public infrastructure and that which is sold by the delivery body to cover its costs.

The Misato Chūō land readjustment project

In the 1990s, the Japanese government approved plans for a new express train that would connect Akihabara in central Tokyo with the Tsukuba Science Park. The new line would pass through and build a new station at Misato, an area on Tokyo’s northern fringe with a mix of farmland and suburbia.  

Recognising that this development would give the area superb transport links straight into the heart of Tokyo, Misato’s municipal government proposed designating the land around the new station for land readjustment. The proposal was approved by the Saitama Prefectural Government, which holds statutory authority over such designations. 

Local landowners then together formed a Land Readjustment Association – the Misato Chūō Land Readjustment Association – which became formally established once the legally required two-thirds of landowners representing two-thirds of the land area had consented, and its founding documents were endorsed by the Saitama Prefectural Governor. The project covered about 115 hectares of farmland surrounding the future station, coordinating the replotting of roughly 3,000 parcels of land. Landowners contributed around 35-40% of their holdings to be used for public facilities and for reserve land. The project was majority financed by reserve land sales, but it did also receive government subsidies towards the costs of significant new infrastructure, like major roads.

Roads, sewerage, parks, and a community centre were laid out in advance of the railway’s 2005 opening, and existing buildings were either relocated or integrated into replotted parcels. Upon completion, each landowner received a smaller but more valuable plot, and cash equalisation payments to ensure that gains and losses were balanced across participants. Average land values hugely increased, from about ¥151,000 per m² before the project to ¥295,000 per m² after completion (an increase of roughly $1,700 per m² to $2,600 per m²)¹⁶, while the district gained schools, shops, and mid-rise housing linked directly to Akihabara in under 30 minutes. Today, the train services that run between Akihabara and the Park carry over 390,000 people daily, with many passengers boarding and alighting at Misato. ¹⁷

Valencia, Spain¹⁸

The Spanish region of Valencia has developed a very different model to Japan’s, forced to innovate after initially struggling to make the national land readjustment system work well. Under the reparcelación system that Spain first introduced in its 1956 Land Act, an area could be designated as a ‘developable’ for land readjustment by the local municipal plan. This designation gave landowners in that area development rights. But it also gave those landowners obligations: if they were to take advantage of the designation and redevelop, then they must also finance infrastructure and cede land for public uses. However, the land readjustment process introduced by the 1956 Act was burdensome and demanding of landowners.

In order to actually begin land readjustment and take advantage of their development rights, the Land Act required landowners to form an association called a Junta de Compensación. The formation of the Junta plays the role that the ballot stage does in the Japanese land readjustment system: the Junta could not be formed unless landowners owning at least 60% of the affected land agreed to participate. If this threshold was reached, the remaining 40% of the land was automatically incorporated into the development scheme, whether or not the landowners consented.

Once created, the Junta’s first job was to draw up two planning documents, one replotting the area and one making provision for new infrastructure and how it would be financed. Under the act, these plans would then need to undergo public consultation before being approved by the municipality. Pending the approval of these planning documents, the land would then be developed, the plots shared back out to landowners, and the land set aside for public use ceded to the municipality for development. 

Most small landowners are not developers and have no developing experience, but the land readjustment process introduced by the 1956 Act relied heavily on landowners to lead on the process and take major decisions. That meant landowners had to do the work of establishing who owns what bit of land in the designated area and creating a plan for replotting and redistribution. 

With few land readjustment projects initiating or completing, the Spanish government responded by revising the 1956 Act in 1976 to introduce the role of the agente urbanizador: the urbanising agent. The agent’s role was to redistribute the replotted land and create new infrastructure as part of the redevelopment. This relieved landlords themselves of the need to negotiate with one another and draw up plans themselves. 

However, while an improvement on the previous system, urbanising agents struggled to successfully negotiate with landowners, over whom they had little leverage. As with the typical negotiated sales process, individual landowners were often motivated to delay negotiations, holding out for the offer of a better plot or simply preferring not to cooperate with the land readjustment scheme at all. Agents had no way to compel landowners to cooperate or negotiate and so often came to an impasse.

In recognition of this problem and the subsequent dearth of land readjustment projects, the region of Valencia made several changes to its land readjustment process in 1994, including: 

1. Urbanising agents became able to get municipal approval for forced land readjustment if landowners refused to cooperate.
2. The use of an urbanising agent was made mandatory and the selection of agents through public tender became mandatory.

Would-be developers now competed in cost, quality and delivery times to win tenders to develop land in Valencia. Replacing amateur small landowners as the driving force behind readjustment projects, these professional developers could then negotiate with landowners knowing, knowing that the municipality could step in to break the veto of a holdout landlord. No more could certain landowners stall a project in the hope of forcing a better offer from the urbanising agent.

The effects of these changes were dramatic. The process of forming a junta had taken an average of three to five years prior to 1994. Post-1994, it took only an average of three to seven months from the start of the tender process for an agent to be chosen. The number of new land readjustment projects in Valencia per year rose from roughly 40 between 1990 and 1994 to 240 by 1998. Valencia’s success has influenced the rest of Spain, with the majority of other Spanish regions making similar reforms.

Conclusion

There is strong political consensus that Britain needs to build more homes and more infrastructure. But major projects of this kind will often generate strong and sustained opposition from the group of people most affected by it. Land readjustment seeks to win the cooperation of those most likely to oppose a development by giving them a fair share in the value uplift that it will create. It recognises them as rational actors who can be negotiated with and gives them a material stake in the development.

Such a system is not alien to Britain. As this paper has shown, England has its own history of using supermajority-backed land reorganisation to consolidate land rights and unlock land for more productive uses. Nor is it theoretical: in countries including Japan and Spain, modern land readjustment plays a key role in large scale urban and rural development projects. 

A modern British land readjustment system can help make developments in highly desirable areas more possible by turning opposition to such changes into support. Land readjustment cannot independently “solve” the problem of British planning – that it is consistently very difficult to get things built in many parts of the country – but it can help. And it can help in a way that is democratic and non-expropriative. It is time to revive this forgotten mechanism.

The post In Ponzi scheme Britain, parenthood is a luxury appeared first on Onward.

This report provides a comprehensive, forward-looking assessment of how net migration levels will influence house prices and rents in England and Wales (E&W) through the 2025–2029 parliamentary term. Drawing on global and UK peer-reviewed research, it models two scenarios: a high-migration case (≥400,000 UK net annually, skewed low-skilled with real income drags from energy costs and net-zero policies) and a zero-net-migration case (Denmark-style, with productivity gains from reindustrialization and cheaper energy). 

Key assumptions incorporate September 2025 data: E&W dwelling stock 27.3 million (up from 27.1 million mid-2024, with 201,000 completions to Q2 2025); net migration year-ending June 2025 at 250,000 (down from 2023 peaks); natural population change mildly positive early but declining to negative by 2029 per ONS projections; annual supply growth at 0.8%. Income effects are factored via elasticities (0.6 median), with high migration depressing wages -0.5% annually and real incomes -1% (energy cap at £1,755/year, 50% above pre-crisis); zero migration boosting real incomes +1% via +0.5% productivity and energy relief.

Results: High migration yields +2.0–3.0% cumulative price rise and +1.7–2.5% rents (modest due to supply and drags); zero migration -1.0–1.8% prices and -0.8–1.5% rents (cushioned by income gains). Supply constraints amplify urban pressures. Policy must balance migration with housing delivery to mitigate affordability risks, leveraging reindustrialization for sustainable growth.

1) Introduction

The UK’s housing market faces persistent affordability challenges, exacerbated by population dynamics and supply inelasticity. As of September 2025, E&W house prices stand at £290,000 average (up 2.5% year-on-year), while rents have surged 7.8% to £1,235/month, outpacing wage growth at 4.2%. Net migration, which accounted for 90% of UK population growth in 2024, remains a pivotal driver – year-ending June 2025 net at 250,000, down from 745,000 in 2023 but still above historical norms due to student and work visas.

This research synthesizes peer-reviewed evidence to project impacts through 2029 under constrained supply (0.8% annual net additions). It contrasts a continuation of high migration (≥400,000 net, per government baselines) with a restrictive Denmark-style zero-net target, overlaying current trends like declining natural change and income effects from energy prices/productivity.

Forward projections are critical: ONS estimates UK population reaching 70 million by 2026, driven by migration amid natural stagnation. Without intervention, imbalances could widen inequality, with low-income renters hit hardest. This analysis employs causal elasticities from studies like Saiz (2007) and MAC (2018), adjusted for UK specifics, to deliver actionable insights for policymakers and investors.

2) Literature Review: Global and UK Evidence on Immigration, Incomes, and Housing

Peer-reviewed research underscores immigration’s demand-side pressure on housing, modulated by incomes and supply. Globally, a 1% population increase from immigration raises rents 0.6-1.2% and prices 1-2% (Saiz 2007, Journal of Urban Economics; Ottaviano & Peri 2007, Journal of the European Economic Association), with effects 2-3x larger in inelastic markets (e.g. UK’s planning constraints, supply elasticity 0.5-0.7 vs. US 1.5).

US studies highlight short-term spikes fading via native mobility: Monras (2020, American Economic Review) finds low-skilled inflows reduce rents 0.5-1% long-run due to out-migration, but +1% short-run. Research on “white flight” – the out-migration of white residents in response to non-white immigration – further explains these dynamics. Boustan (2010) estimates that white flight accounted for about 20% of postwar suburbanization in US cities during the ‘Black Great Migration’, redistributing demand and mitigating urban housing pressures. 

More recently, Pan (2024) documents similar patterns of white families leaving affluent California suburbs as Asian immigrants arrived, linked to school competition, which stabilizes local prices through reduced net demand. These mobility patterns contribute to persistent segregated housing, where ethnic enclaves form and influence rents and values over time. 

For instance, Saiz and Wachter (2011) analyse how Hispanic immigration growth led to increased segregation in US metro areas from 1970 to 2000, resulting in divergent price trajectories: rising values in white suburbs (+5-10% premium) and slower rent growth in immigrant-heavy neighbourhoods (0.5-1% annual dampening), perpetuating affordability gaps across racial lines. 

Canada and Australia show stronger persistence: Akbari & Aydede (2012, Regional Science and Urban Economics) estimate 0.8-1.2% price rises per 1% inflow in Toronto/Vancouver, driven by high-skilled immigrants; Stillman & Maré (2008, Economic Record) 0.9-1.1% in Sydney, amplified by urban concentration. European evidence aligns: Sanchis-Guarner (2017, LSE) reports 3.3% price and 1% rent increases per 1pp immigration rate in Spain, with +24% indirect amplification from native co-location. Gonzalez & Ortega (2013, Journal of Urban Economics) confirm 2% short-term prices in Spain; Mussa et al. (2017, Switzerland) null overall but +0.5% in high-flow areas.

UK-specific: MAC (2018) attributes 1% national price rise per 1pp population growth, 2-3x in the South East; Whitehead et al. (2011) links 20-30% of 1990s-2000s growth to migration. Sá (2015, Economic Journal) finds local -1.6% prices per 1% low-skilled inflow due to high-income native flight (0.85% outflow), but national net positive. Meta-analyses (Card 2009) affirm median 1% elasticity, higher for rents (quicker adjustment).

Shor-term spikes happen after an influx of immigrants (especially lower skilled workers) move into a city or neighbourhood; housing demand shoots up fast. More people mean more competition for rentals or homes, so prices and rents jump quickly. The reason natives (long-time residents) often pack up and move to nearby cheaper areas. This “out-migration” frees up housing supply, balancing things out and cooling price and rental growth. The initial jump does not last forever, as it eases off over time. 

In short, immigration causes a quick housing squeeze, but locals relocating to avoid the crunch eventually spreads out the pressure. This makes things more affordable again, but at what cost. It is like a crowded party, new guests arrive and it is packed, but some of the old-timers slip out the back door, so everyone gets more space. 

Incomes refine this: Housing demand elasticity 0.5-1.0 to income (DiPasquale & Wheaton 1996, Journal of Urban Economics). Immigration’s wage effects: -0.5–2% for low-skilled natives short-term (Dustmann et al. 2013, UK; Monras 2015, US) – dampen via reduced affordability, stabilising rent-to-income ratios (Card 2005, Journal of Economic Literature). 

In layman, immigration adds demand pressure by hurting low-skilled natives’ wallets (through higher housing costs), which leaves them with less to spend on housing. Perversely, it statistically takes the edge off the affordability crunch. It is not a fix. Prices still rise a bit, but it in effect prevents overheating. A native squeeze for market ease. But over time, say 3-5 years, people adjust (better jobs or moving to cheaper locations), and things balance out. 

If wages rose instead (from skilled immigration), it would still turn housing into a bidding war where low-skilled natives would lose ground the fastest. They would end up renting worse places further out, commuting longer, all the while feeling the pinch. Skilled immigration might supercharge the economy through improved GDP, but it comes with costs if policymakers do not build more homes fast. Otherwise, it is a rough ride for those at the bottom.

Yet although skilled immigration may exacerbate housing pressures for low-skilled natives – sparking a bidding war that pushes them to distant, subpar rentals and longer commutes – research shows it does not stoke anti-immigrant attitudes. Instead, it cools nationalist voting intention by 0.34 standard deviations per 3.1% population rise, namely through economic optimism. This is in stark contrast with low-skilled inflows that ignite fears over jobs and welfare, amplifying it by 0.73 standard deviations per 6.1% rise (Moriconi et al. 2019). 

Skill complementarities refer to the economic synergy where immigrants’ skills – particularly high skilled ones like engineers or managers – complement rather than compete with native workers. It allows low-skilled natives to specialise in routine or manual tasks while immigrants drive innovation and oversight, ultimately lifting overall wages and productivity across the labour market. This dynamic, as detailed in Peri and Sparber’s 2009 study in the Review of Economics and Statistics, generates modest but positive wage gains of 0.2-0.5% for natives through task reallocation, with no significant displacement for low-skilled groups. 

Similarly, Lewis & Peri 2015 handbook chapter quantifies productivity boosts of +1-2% from such inflows, as immigrants fill knowledge gaps that expand firm output and create spillover jobs. However, these benefits can be muted by countervailing fiscal drags, such as increased taxes to fund public services for newcomers (some of which never become net contributors), or external shocks like energy price hikes that erode real incomes by -0.5-1%, which mute demand elasticity through curbed household spending power. 

On the other hand, homeownership acts as a natural hedge, converting price appreciation into wealth effects equivalent to 6–8% of rental income (Ottaviano & Peri, 2007). This enables homeowners to offset affordability strains through equity extraction or psychological resilience, though this exacerbates intergenerational dives as renters – often low-skilled natives – bear the brunt without such buffers.

Recent UK trends: Post-Brexit, low-skilled skew depresses semi-skilled wages -0.5% (Dustmann et al.); net-zero policies add between £500-£800/capita tax burden, hitting real incomes amid 50% higher energy costs. Reindustrialization could boost productivity +0.5–1% (NIESR 2025), echoing Denmark’s wage stability under tight controls.

Synthesis: Base 1% elasticity adjusted +20-50% for constraints, -25-50% for wage drags. This informs scenario modelling, emphasizing targeted migration for balanced growth.

3) Methodology and Assumptions

Projections use a dynamic cohort model compounding annual changes in population, stock, and demand, grounded in elasticities from reviewed literature. Population = prior + migration + natural; effective demand shock = (migration % of pop * base elasticity 1%) * supply adjustment (+50% for inelasticity) * income elasticity (0.6). Prices/rents: +1% per 1% positive shock; symmetric negative for excess supply (Monras/Sá).

Updated Baselines (September 2025):

• E&W Population: 62.2 million (ONS mid-2025 estimate, up 0.6% from mid-2024 via 250k net migration year-ending June).
• Dwelling Stock: 27.3 million (England 25.8m, Wales 1.5m; +201k completions to Q2 2025, net additions 187k since July 2024 per MHCLG).
• Supply Growth: 0.8% annual (compounding; 218k/year average, aligning with 201k Q2 completions and Wales 4,631 for 2024-25).
• Natural Change: ONS 2022-based projections show shift to negative: +5k (2025), 0 (2026), -5k (2027), -10k (2028), -15k (2029) for E&W (cumulative -25k; fertility 1.45, aging-driven).
• Migration Share to E&W: 95% (ONS patterns).

Scenario Assumptions:

• High Migration: 400k UK net annually (baseline projection; 40% low-skilled skew). Wage drag -0.5% (Dustmann), real income -1% (energy cap £1,755 Oct-Dec 2025, +2.4% elec/+0.7% gas; 50% above pre-crisis). Demand adjustment: -0.6%.

• Zero Migration (Denmark-Style): Net zero; no low-skilled drag. +0.5% productivity (reindustrialization, ONS Q2 2025 +1.5% output/hour amid GVA +5.1%); +0.5% energy relief (falling caps). Real income +1%; demand boost +0.6%.

Household formation: Immigrants +1.5-2x initial demand (rental focus), converging. Regional: National averages, +2x South-East. No major shocks (e.g., recessions) assumed; sensitivity ±20% for extremes.

4) Scenario Results

High Migration Scenario

Sustains 0.61% annual pop growth (380k E&W net + declining natural), but 0.8% supply creates -0.18% average pressure pre-income. Low-skilled skew and energy drags (-1% real income) reduce effective demand to +0.37%, yielding +0.4-0.6% annual prices (cumulative +2.0-3.0%). Rents +0.3-0.5% annually (+1.7-2.5% cumulative), pressuring private sector (60% immigrants rent initially).

Cumulative: +1.90m pop (+3.05%); stock +1.10m (+4.02%). Urban amplification: London +4–6% prices.

Zero Migration Scenario

Pop flat to -0.02% (natural only), -0.80% pressure pre-income. Gains (+1% real income) offset to -0.20%, limiting declines to -0.2–0.4% annual prices (-1.0–1.8% cumulative). Rents -0.2–0.3% (-0.8–1.5%), enhancing affordability but risking underutilisation.

Cumulative: Pop -0.05%; stock +1.10m (+4.02%). Northern regions see sharper softening (-2–3%).

Contrast: High scenario adds £5,800–8,700 to average prices by 2029 (+£71-£118/month rents), but wage drags erode gains for low earners (rent-to-income +1-2%). Zero eases by £2,900-£5,200 (-£25-£42/month), boosted by productivity (ONS Q2 2025 +1.5% output/hour). Supply at 0.8% mitigates 40% of high-migration pressure vs. 0.2% supply (+6-9% prices).

Sensitivity: +10% migration → +0.5% extra prices; -20% supply → doubles impacts. Energy relief in zero (falling caps) sustains demand, per IPPR (2025).

5) Summary of Results

Evidence confirms immigration’s net positive on E&W housing costs (median 1% elasticity), but incomes and supply temper effects. High migration (400k net) drives modest inflation (+2-3% prices to 2029), cushioned by 0.8% supply yet strained by -1% real income drags – exacerbating inequality, as low-skilled renters face +7–10% effective costs (Sá 2015). Zero migration flips to deflation (-1-2%), with +1% income gains from reindustrialization (NIESR) and energy caps (£1,755, down slightly Oct 2025) restoring affordability, though risking stagnation (fewer construction workers, per my developments).

Broader dynamics: Declining natural change (-15k by 2029) heightens migration’s role; ONS projects 73.7m UK by 2036 without controls. Urban-rural divides persist. South East +4-6% vs. North -1-2% in zero scenario. Politically, low-skilled immigration risks fuelling nationalist tendencies among low-skilled natives through welfare fears and cultural unease, boosting anti-immigration votes (e.g. +1-2% for populist parties), while skilled inflows may temper such backlash by enhancing economic perceptions and reducing segregation-driven hostility. 

6) Investment, Policy, and Political Implications

For investors, the high migration scenario (i.e. lots of migration) means urban rentals would witness significant demand-side pressure, as more people move to urban areas, spiking demand for apartments in towns and cities. The zero migration (Denmark net migration targets) flips it, cheaper family homes in quieter regions (e.g. North or Midlands), as prices soften 1-2%. 

For policymakers, the findings demonstrate strong rationale for prioritising significant increases in housing supply (target 400k-500k/year via meaningful planning reform); skill-selective visas minimise drags (Ottaviano & Peri). Reindustrialisation (+0.5% productivity) and pragmatic net-zero (energy relief) unlock +1-2% real growth, balancing Denmark’s stability with UK’s dynamism. 

Rationale: matching migration-driven demand (e.g. 1 extra home per 2-3 new residents), clearing historical shortages, and addressing low-skilled natives concerns that have previously been left unaddressed. 

To achieve this, adopting a Danish approach to zero-net migration, coupled with its “parallel societies” legislation that would dismantle ethnic enclaves through mandatory integration and dispersal, offers a compelling justification for addressing the housing affordability crisis among low-skilled natives in the UK. Evidenced by the -1.0 to 1.8% cumulative price declines and -0.8-1.5% rent reductions by 2029 under restricted inflows, as illustrated in the analysis. 

By curbing low-skilled migration – projected to depress native wages by -0.5% and exacerbate real income strains – the model directly mitigates job competition fears, which research links to heightened nationalist voting (e.g. +1-2% boosts for populist parties like UKIP per Moricono et al 2019). This also counters white flight dynamics, where native out-migration (0.85% per 1% immigrant inflow, as per Sá 2015) perpetuates segregated housing and divergent price trajectories (Saiz & Wachter 2011). This is achieved by stabilising neighbourhoods and reducing cultural unease that amplifies welfare strain perceptions, which is twice as potent as labour concerns for low-skilled attitudes (Dustmann & Preston 2007). 

Outcomes for Danish policies show improved economic integration for dispersed residents, though with short-term displacement risks (Hangartner et al. 2019). UK adoption could foster balanced growth and simultaneously temper anti-immigration backlash (Edo et al. 2019). In doing so, Britain can avert the high-migration scenario’s urban rent surges, ultimately harnessing demographic stability that creates more inclusive housing markets. 

While these findings quantify the economic and political impacts of different migration paths, they also point to a deeper undercurrent that numbers alone cannot explain. Housing markets are, at their core, social organisms. All shaped by trust, identity, and the willingness of individuals to live alongside one another. To understand the full implications of a Denmark-style reset, it is necessary to examine the cultural and civic dimensions that underpin economic stability.

6A) Cultural Integration and Cohesion: The Social Capital Dimension

The housing and income effects of migration cannot be separated from their social impact. The question is not only whether Britain can build enough homes but whether it can remain a community that recognises itself. The phrase “island of strangers”, said by Sir Keir Starmer but later retracted, inadvertently captures a deeper unease: an enclosed kingdom come undone, its symbolic unity eroded by estrangement. This metaphor clarifies that demographic change reshapes not just markets but the civic contract that sustains them.

This sociological layer explains why white-flight and segregation dynamics are more than just economic. They reflect what Robert Putnam (2006) called the “constriction effect” of diversity. In Diversity and Community in the Twenty First Century, Putnam found that ethnic heterogeneity often reduces both bonding (in-group) and bridging (out-group) social capital. In diverse neighbourhoods, residents “hunker down”, trusting neither strangers nor neighbours. The short-term result is lower civic engagement and weaker reciprocity. Conditions mirrored in housing churn and urban unease across English cities.

Putnam’s framework helps explain the political feedback loop identified in this paper: rapid inflows of immigrants raise rents, fuel competition, and depress wages for the least mobile, while falling social trust magnifies grievance. Economic pressure becomes cultural dislocation. The “parallel societies” policies Denmark adopted, dispersing migrant communities and tying residency to integration, represent a conscious attempt to reverse this spiral by rebuilding the moral infrastructure of trust that markets quietly depend on.

Bhikhu Parekh’s Political Theory and Multicultural Society (1972) provide the theoretical foundation for that approach. Parekh argued that welfare states were design for cultural homogeneity, citizens sharing assumptions about duty, fairness, and contribution. When that consensus weakens, redistributive solidarity falters. His warning helps interpret Britain’s experience: even when migration is fiscally neutral, it strains perceptions of reciprocity. Denmark’s legislation seeks to restore that civic equilibrium, ensuring that shared benefits correspond to shared norms. In the British context, a similar principle could link immigration control to community integration, rather than simple restriction.

Benjamin Schwarz’s Unmaking England (2016) adds a cultural-historical perspective. Schwarz argued that mass immigration after 1997 dissolved the tacit consensus on English identity: “obliterating the national culture Orwell described”. While polemical, the insight is valuable. National identity functions as a form of social capital, and when it fragments, the housing market mirrors that division. Enclaves of concentrated ethnicity coexist with zones of anxious affluence, producing both material and symbolic segregation. The results of these findings quantify this through divergent regional price paths; Schwarz names it as cultural dislocation. 

Together these theories clarify the social consequences of the two migration scenarios. In the high-migration case, the model projects moderate price and rent inflation but falling real wages for low-skilled natives. Combined with Putnam’s constriction effect, this environment breeds distrust: the economic squeeze and the civic chill reinforce one another. Parekh would see this as a breakdown of reciprocity. The sense that “others take more than they give”. Schwarz would call it fragmentation. The zero-migration or Denmark-style scenario, by contrast, offers modest deflation in prices and rents and a potential stabilisation of trust, as demographic predictability allows institutions and communities to re-embed cohesion.

This is not an argument for isolationism. As Putnam notes, the long-run effects of diversity can be strongly positive once societies construct new, encompassing identities. The challenge is managing the transition, reducing the short-term “hunkering down” period through integration and spatial balance. Denmark’s dispersal policies attempt precisely that: converting diversity from a centrifugal to a centripetal force. For Britain, an equivalent would be aligning migration policy with housing delivery and civic planning so that affordability and cohesion advance together.

Ultimately, social trust is capital. When it erodes, the loss appears first in housing patterns: flight, segregation, resentment. And later in politics. Where trust is rebuilt, markets stabilise and divisions ease. Bridging Parekh’s moral theory, Putnam’s empirical sociology, and Schwarz’s cultural diagnosis with the quantitative findings of this report yields the following findings: demographic management and housing policy must treat integration as infrastructure. After all, restoring cohesion is as vital to affordability as bricks, wages, or supply.

These sociological insights reinforce the economic case made earlier: markets and communities rise or falter together. Cohesion, like affordability, is an outcome of design, not accident. The following conclusion brings these threads together, outlining how a balanced migration framework, anchored in both economic realism and civic renewal, can restore stability to Britain’s housing system.

7) Conclusion

A sustainable housing market and political settlement depend on managing both numbers and narratives. Economic pressures alone cannot explain the growing volatility around housing, migration, and trust. As shown throughout this analysis, demographic policy must be understood as part of a wider social architecture: one that aligns migration, wages, and energy with the deeper goal of civic balance.

The modelling demonstrates that high net migration sustains short-term price and rent inflation while depressing real wages for low-skilled natives, conditions that intensify inequality and social friction. Conversely, a Denmark-style zero-net migration framework moderate’s prices, eases rents, and restores affordability through productivity and energy relief. Yet its greatest potential lies not only in stabilising markets but in rebuilding confidence that the system is fair and reciprocal.

Britain’s challenge is therefore one of design. It must calibrate inflows to capacity, link immigration policy to housing delivery, and pursue reindustrialisation that raises incomes rather than merely expanding headcount. In this sense, the Danish model offers a blueprint for equilibrium: demographic restraint paired with deliberate integration.

It is like perfecting a recipe – overdose on one ingredient (unfettered low-skilled inflows) and the pie collapses into unaffordable crumbs for low-skilled natives, fanning nationalist flames amid job competition and welfare strains (Dustmann & Preston 2007; Moriconi et al. 2019). 

The wider reward is political and moral, not merely economic. By addressing the drivers of “parallel societies”, namely spatial segregation, wage stagnation, and mistrust. The United Kingdom can and must transform cultural anxiety into shared purpose. Migration management, when aligned with housing reform and civic renewal, becomes not an act of retreat but one of reconstruction.

The outcome is a market and a society that move together: affordable, stable, and cohesive. The objective is not isolation but balance. A nation that builds enough homes for its people, and enough trust to live within them.

Addendum A: Robustness, Limitations, and Extensions of the Dynamic Cohort Model

Explanatory Note on Model Robustness

Dynamic cohort models, employed here to project population-driven housing demand through compounding annual changes in migration, natural growth, and supply, offer a transparent and flexible framework for medium-term (5-year) forecasting, particularly in stable demographic environments like the UK’s post-Brexit landscape. 

Rooted in cohort-component methods, they excel at disaggregating effects (e.g. low-skilled vs. skilled inflows) and reproducing aggregate trends with low error margins (<5% deviation in historical back tests, per ONS validations). 

However, their deterministic compounding, iteratively applying fixed rates, amplifies small input errors into potentially significant divergences over time, underscoring the need for cautious interpretation in volatile scenarios like policy shocks or economic downturns.

Key Criticisms and Caveats

While the model provides robust baseline estimates (e.g. -1.0–1.8% price deflation under zero migration), several limitations warrant transparency:

• Error Amplification in Compounding: Annual multiplicative updates assume linear progression, but real-world feedback (e.g. falling prices spurring native return migration) introduce nonlinearity. A 10% initial migration overestimate could cascade to 20–50% cumulative error by 2029, especially in tail risks like accelerated depopulation from natural decline.
• Assumption Sensitivity and Determinism: Fixed parameters (e.g. 0.8% supply growth, 0.6 income elasticity) overlook shocks, yielding point estimates without inherent uncertainty. This risks overconfidence; for instance, unmodeled behavioural shifts (e.g. upskilling in response to wage drags) could alter outcomes by ±15–25%.
• Aggregation and Scale Biases: Relying on ONS aggregates masks micro-variations (e.g., urban enclave effects from segregation, per Saiz & Wachter 2011), potentially committing ecological fallacies in regional inferences like South East amplification.
• Equity and Heterogeneity Oversights: Cohorts are treated homogeneously, underplaying disparities (e.g. low-skilled natives’ amplified strain from white flight, Boustan 2010), and ignoring equity metrics like rent-to-income ratios across skill levels.

These caveats do not invalidate the projections but highlight their directional utility; users should apply sensitivity bands (±20%) for policy application. 

Recommendations for Expansion and Scrutiny

To enhance rigor, the model could evolve into a hybrid framework:

• Incorporate Stochastic Elements: Integrate Monte Carlo simulations (e.g. via R’s demography package) for 1,000+ runs, generating 95% confidence intervals (e.g. zero-migration prices: -2.5% to +0.5%) to quantify compounding tails.
• Add Behavioural and Microsimulation Layers: Fuse with dynamic factor models (e.g. DYNAMIS-POP) for feedback like price-responsive migration and disaggregate by skill/income sub-cohorts to capture elasticities (0.5-1.0) more granularly.
• Validation Protocols: Back cast against 2015–2020 data and benchmark against ONS/OBR trials; include scenario trees (e.g. SSP variants for high/low fertility) for external peer review.

This expanded approach would transform the model from descriptive to prescriptive, standing up to academic and policy scrutiny while aligning with best practices in demographic-economic forecasting.

Addendum B: Full Dynamic Cohort Model: Detailed Specification and Implementation

The dynamic cohort model referenced throughout the report is a cohort-component projection framework adapted for housing economics, simulating population evolution and derived demand shocks over 5 years (2025–2029). It is not a pre-built software but a custom, transparent model built on standard demographic methods (e.g. UN cohort-component approach) with economic extensions for housing elasticities. 

Find provided below the full specification, including equations, assumptions, pseudocode, and a Python implementation (verified via simulation). This model was used to generate the report’s tables; it’s deterministic but can be extended stochastically as noted in the Addendum.

The model tracks two primary cohorts for simplicity: (1) Native population (affected by natural change) and (2) Immigrant inflows (disaggregated by skill in scenarios). It compounds annual changes to project total population, net housing pressure, and price/rent impacts via elasticities from the literature (e.g. Saiz 2007 for base 1%; DiPasquale & Wheaton 1996 for income 0.6). Key innovation: Income adjustments as multipliers to capture wage drags/boosts, ensuring realism for low-skilled natives.

The post Making the case for a “purpose-built young professional accommodation” class appeared first on Onward.

The post Thinktank calls for new asset class to boost housing for young professionals appeared first on Onward.

This paper proposes the creation of a new sui generis (use of its own kind) residential building type for young professionals: Purpose Built Young Professional Accommodation (PBYPA). PBYPA will be exempt from certain key regulations, allowing the creation of compact studio or micro apartments for young professionals that prioritise affordability and central location over other amenities. 

The Government has pledged to build 1.5 million homes, but the urban housing crisis remains particularly acute and the solutions proposed by the Government fail to prioritise urban densification. This is contrary to the benefits of agglomeration and ignores the market of young people flowing into cities for work. PBYPA would fill this gap in economic hubs where demand from young professionals (aged up to 35) is great, including London, Manchester, Bristol, Bath, Brighton and Leeds.

The mechanisms to create PBYPA already exist. In London, Co-Living and Purpose Built Student Accommodation are exempt from Nationally Described Space Standards, or minimum space requirements, and have special affordable housing requirements. But neither of these existing classes serve or adequately serve young professionals. 

Beyond meeting housing demand, this new category, PBYPA, takes advantage of the filtering phenomenon to alleviate housing shortages (the process through which the provision of a new dwelling reduces pressure on existing stock by diverting demand), brings economic benefits, and adds practical weight to the YIMBY movement. It offers a realistic, supply-led response to the housing crisis, in the form of a new investable asset class, which could be achieved with public consultation, legal changes to the use classes order, and updates to the National Planning Policy Framework (NPPF).

Introduction

This paper makes the case for a new sui generis¹ residential use for buildings: PBYPA. Designed for young professionals, PBYPA will be characterised by targeted regulatory exemptions to enable young professionals to trade certain amenities, such as space, for greater affordability and proximity to urban employment hubs, whilst providing a new residential asset class for investors.

The housing crisis is concentrated in cities and is acutely felt by the younger generations that live and work in them. But, there remains an absence of a targeted supply side solution to address their housing needs, especially in London where regulations and stringent design standards are particularly restrictive for supply. There has instead been a reliance on demand side solutions including the Help to Buy: Equity Loan Scheme, the proposed relaxation of mortgage lending rules for first time buyers, and shared ownership schemes.^{2 3}

Rents are least affordable in cities, as well as in the commuter areas around them.⁵ According to the ONS’ rental affordability ratios, which compares a household’s gross median income to rent for the average priced home, London, Bristol, Bath, Brighton, Manchester, and Leeds are all amongst the least affordable.⁶ Travel-to-work areas  around Manchester, including Oldham, Wigan and Bolton have also had rents surge 31% in the three years to 2025 alone.⁷ 

The Government does not currently have a sufficient plan to address the housing crisis in the areas where it is worst and is missing a key opportunity in not delivering for the young professional market. The current Government has pledged to deliver 1.5 million homes by the end of this Parliament, but it lacks a focus on cities and market opportunities having rolled back on the urban uplift⁸ despite reintroducing mandatory housing targets.⁹ 

The effect of the housing crisis is particularly pronounced upon younger generations. Young people are far less likely to own a home than previous generations and are more likely to rent privately. From 1989 to 2013, home ownership among 19–29 year-olds fell from 23% to 8%.¹⁰¹¹ Home ownership among young people did rise from 8% to just over 12% between 2013 and 2021, but this remains around half the rate of 30 years ago.¹² 

Young professionals find themselves ineligible for Purpose Built Student Accommodation, and many of them are unable to afford the premium Co-Living rents or to buy a home. This means they must compete with the rest of the market for the limited existing stock on offer to privately rent.   

The need for a new bespoke residential use 

2.1 There is great demand for young professionals to live in urban areas

Cities are the most popular place for graduates to move to, and although London remains the most powerful magnet for young talent, other cities are also major draws. Research finds that when young graduates are moving towns, 18% relocate to London (12% to inner London, 6% to outer London). But 23% of graduates move to other major cities, the top five outside of London being: Brighton & Hove, Manchester, Bristol and Leeds. The combined migration of graduates into these cities exceeded Inner London’s 33%.¹³ But the share of graduates remaining in their home city by age 24 was highest in London. 

Figure 2: Graduates tend to move from the places they sat their GCSEs to live in urban areas

Source: ONS¹⁴ 

In absolute numbers, shown in Figure 2, graduates being pulled into cities outside of London is evident, representing 41,000 graduates. Inner London alone attracts 21,155 people and outer London 11,170, combined to just over 32,000 people. London retains a significant volume of its own graduates too.¹⁵ 

There is a clear net movement away from smaller towns and small built up areas (BUAs) to larger urban areas, so there is a strong flow of demand of incoming young professionals to urban cores, not solely in London although predominantly there. This means young professionals are actively increasing demand on the general housing market in urban areas.

Urban population growth is greater than that of non-urban areas. Between 2001 and 2019 the population growth of cities has been greatest. Inner London’s population grew 27% in this period, outer London by 19%, and cities outside of London by 16%.¹⁶

Figure 3: Population growth in England and Wales, mid 2001 to mid 2019 (BUA = Built Up Areas)

Source: ONS¹⁷

It is unlikely that the flows of young graduates and non-graduates into cities and their surrounding areas will come to an end. Despite rents being on the rise, young graduates still want to move to cities, for reasons of work, amenities and convenience.¹⁸ This has significant agglomeration benefits, inducing growth.

2.2 The current offer to young professionals is inadequate

The current offer to young professionals unable to buy a home or live with family consists of shared living models including Co-Living, HMOs and privately rented flat shares.

Co-Living is a fairly new asset class and targets high-earning young professionals with an offer of all-inclusive bills, flexible contracts and high-quality on-site amenities.¹⁹ 

But it is a premium product. Average rents for Co-Living range between £1,550–£1,750, approximately 74% and 84% of a young professional’s monthly income.²⁰²¹ Consequently, the average age of Co-Living tenants is 28, and over a quarter of residents are aged 35 or older.²²  In short, it is out of the reach of and indeed not aimed at the vast majority of young professionals looking for accommodation in cities. 

The alternative option for young professionals outside of Co-Living and living with family is private renting. This often lacks affordability, consistency and predictability, which is particularly bad for new entrants to the labour market. Affordability is an acute issue, as rent inflation tends to outpace income, driven by high demand and sluggish supply, which places significant strain on tenants.²³ Approximately 40% of households in the private rental sector are in the lowest third of incomes.²⁴ The level of financial insecurity arising from a lack of adequate housing provision for young people contributes to their displacement. In 2023, 48% of renters in their 20s left London.²⁵ This coincided with a 16% rent surge.²⁶ This threatens the benefits of agglomeration that urban density brings to workers and the wider economy. 

More often than not, young professionals seek out house shares. Some of these fall into the legal category of a House in Multiple Occupation (HMO), where three or more unrelated tenants share facilities such as a kitchen or bathroom. This is a growing asset class with the number of HMOs having risen 2.3% over the last year.²⁷ Alongside students and health care workers, young professionals are classed as this asset class’s primary market.²⁸ 

But, there is a clear lack of affordable supply driven by accommodation shortages. In London alone in October 2023, the house sharing website Spare Room recorded 76,898 people looking for a spare room, but only 16,803 listed on the website.²⁹ 

Furthermore, in combining resources to split rents in homes with multiple bedrooms in cities or within reach of cities, young professionals outbid families who could otherwise live in the space. In this way, they feed into urban affordability issues. The lack of a housing solution for young professionals therefore contributes to the broader housing crisis. As young professionals have nowhere specifically catering to them they must compete with the wider market for limited existing stock. In an already overcrowded housing market, this carries repercussions for renters born in the area, and families.

2.3 Overly restrictive regulations and standards constrain supply

Rigid regulations on design and safety standards are a significant constraint on housing delivery. But they are especially burdensome for urban development, and the delivery of purpose built rental models that rely on efficiency and density to attain both viability and affordability. While there are a significant number of regulatory burdens, for simplicity this discussion focuses on those that a new residential development may be exempt from as new builds.

A core issue for the delivery of density and affordability is the impact of minimum space requirements. The Nationally Described Space Standards are not a planning regulation, but simply a planning standard. In England, this sets a minimum space standard of 37m² for a one person apartment, despite the average space consumption being 25m².³⁰ Albeit not mandatory across the country, the London Plan³¹ automatically applies the standard to all developments as a requirement, and the space standard applies to all conversions via the permitted development rights route also. The 37m² minimum unit size described under Nationally Described Space Standards (NDSS) is around 50% larger than what the average renting Londoner can actually afford.³² And more than 75% of London residents can only afford to rent or buy property less than £700 per square foot, of which only 47% of the last 5 years of housing stock has delivered in London.³³ 

Existing sui generis use classes, namely PBSA and Co-Living, tend to be exempt from the severity of minimum space requirements. PBSA, for example, is exempt from minimum space standards, as is Co-Living; so long as the provided amenities compensate for smaller spaces.³⁴³⁵ This makes PBSA both much more viable as an asset class and an essential residential use classification for urban regeneration. 

Affordable, or more accurately, subsidised housing requirements also act to make developments less viable in the first place, and the homes that are built in factor more expensive overall. The current requirements for developers to deliver affordable housing, or housing priced at 80% of the market price, naturally require the developer to cross subsidise the cost of delivery via higher prices paid for by the end tenant of non-affordable housing units in the development.  This counters the market forces that enable greater supply to gradually reduce market prices. The target for developers to deliver 35% of their stock as affordable housing in London has recently been dropped to 20%, effective until March 2028 or the publication of the new London Plan, to boost urban housebuilding as an acknowledged barrier to delivery.³⁶

Design standards such as dual aspect add further limitations to the delivery of density. Dual aspect homes may have enhanced daylight and ventilation, but these come at the premium  of reducing deliverable units, increasing the cost of delivery and, consequently, raising rents. Although this measure has been temporarily rolled back as an emergency measure to kickstart housing in London, the return of this policy in future may thwart the efficient floorplate design of new developments.

Similarly the blanket application of emerging fire safety regulations threaten the viability of midrise developments. From September 2026, new regulations in England will require second staircases in all residential buildings over 18 metres in height, from the previously proposed 30m, which has been effectively enforced across London through the Greater London Authority’s planning system since 2023.³⁷ This move is intended to enhance the UKs world-leading building safety standards.³⁸ Yet the Government’s own impact assessment shows the costs of this measure are 294 times greater than its benefits. Indeed, as currently modelled, lowering the threshold for buildings between 18 and 50 metres will not save a single life over the 70 year modelling period.³⁹⁴⁰ This is partly because modern developments are typically equipped with sprinklers, smoke ventilation, and 24-hour management, so that this rule provides limited additional safety benefits while materially increasing costs and complexity. Having a higher, 50 metre threshold would keep England in line with comparable European countries including Ireland, France and Germany.⁴¹

2.4 Precedent shows new residential uses can alleviate housing need while being a viable asset for investment.

The example of Purpose Built Student Accommodation (PBSA) shows us how new residential use classes can increase housing supply. PBSA emerged as a distinct asset class in the 1990s as student numbers increased and was formally recognised as a type of specialist housing with exemptions from certain regulations in the 2010s. PBSA thrives in city centres owing to sustained demand driven by consistent flows of students and shortages in available housing. The top 20 major UK student cities currently need over 230,000 additional beds, with London alone requiring nearly 100,000 to meet demand.⁴² This supply gap is being addressed by PBSA and is supported by strong growth in the value of rents: in 2023/24, an average rental growth value rate of 8.02% was recorded, with the private PBSA sector achieving 9.39%.⁴³ 

The success of PBSA demonstrates that a purpose built asset class can alleviate pressure on the broader housing market in areas where a specific demographic composes a significant inflow of new residents per annum.⁴⁴ In major student cities like Nottingham, Leeds, and Manchester, students can make up over 30–40% of local renters.⁴⁵ Without purpose built accommodation, students would naturally enter the private rental market to compete with other local renters. PBSA significantly reduces this pressure, housing 31% of full-time students across the country in 2023.⁴⁶

Financially, PBSA investments offer net yields of 6–8%, and so outperform traditional build to let properties.⁴⁷ And institutional confidence is evident: approximately £3.87 billion was invested in the UK PBSA sector in 2024, up 14% on 2023.⁴⁸ Notably, PBSA offers passive, professionally managed income streams and occupancy rates often exceed 95%.⁴⁹

2.5 ‘Filtering’ means all will benefit.

A new sui generis residential use for young professionals will not only help those people find accommodation and work but help to alleviate the pressure of the housing crisis for everyone through the effects of filtering.

Filtering describes the way in which new housing, even if aimed at a specific group, enables mobility, freeing up housing stock in a way that reverberates throughout the housing market. For example, the building of luxury housing meets local and national opposition because of the perception that it does nothing to help people on lower incomes.  

But because of filtering, new luxury housing makes housing more affordable for all, because it allows higher income households to “move up” the housing ladder, freeing up their previous homes for others. This creates a chain effect: the wealthy move into luxury homes, middle income households move into the newly vacant properties, and lower income individuals gain access to more secure accommodation. The market, therefore, benefits from a cascading effect of availability.⁵⁰

A new, sui generis, residential use class aimed at young professionals would work in the same way. Far from only benefiting this particular cohort of people, this new asset class would work, through filtering, to ease pressure on HMOs and the wider private rental market, freeing up housing stock for families and other groups. But these benefits are not widely discussed and lack formal recognition in planning. 

Introducing Purpose Built Young Professional Accommodation 

Purpose Built Young Professional Accommodation (PBYPA) would explicitly target graduates and early career professionals moving into and within cities facing an increasingly constrained housing supply. PBYPA represents a natural and logical evolution of the PBSA and Co-Living models, with benefits not only for young professionals but for everyone by relieving pressure on the housing market. 

3.1 Who will live in Purpose Built Young Professional Accommodation?

The tenancy will be for young professionals only. This means that tenants must be: 

• employed full-time;
• Or, in part time employment and within two years of finishing a part-time bachelors, masters, PhD or post-doc;
• under the age of 35. 

Demand in this demographic that this new asset class targets is underpinned by affordability pressures in the mainstream private rental sector with few alternative options, as explained above. However, it may be that the operators of these buildings identify more effective criteria, and provision should be made for that. 

3.2 Who will build Purpose Built Young Professional Accommodation?

The assets will be built by developers under a build to rent (BTR) framework, but they will be bought by institutional investors and managed thereon. This will mean that, as an institutionally owned and operated asset, PBYPA will benefit from professional management, long-term capital alignment, and operational scale. This drives consistent service quality, stronger tenant retention, and stable income streams, while reducing exposure to individual unit sales. The model should enhance resilience, align investor and developer interests, and, in turn, deliver a scalable, income-producing asset class.⁵¹

Like PBSA and Co-Living, PBYPA would leverage operational efficiencies and professional management, offering investors stable occupancy and resilience to wider economic volatility, but would go further in the regulatory exemptions made for this new asset. Returns would be attractive: as PBSA and Co-Living exceed traditional residential returns PBYPA could achieve the same effect. PBYPA currently sits at the intersection of undersupplied rental housing and proven investment appetite, making it a viable and scalable model for city centres.

One of the key opportunities to develop PBYPA rests with the availability of underutilised brownfield land in urban areas.⁵² Where these areas fall in proximity to existing infrastructure and employment hubs, they should be earmarked for higher density living, led by PBYPA. In London, the approach to underutilised land for development could extend to include the selective and economically logical repurposing of Strategic Industrial Land (SIL). Such redevelopment could include mixed-use or managed residential models to be justified without loss of critical employment capacity.⁵³

3.3 The Planning Model

In order to deliver PBYPA, this asset should be introduced as a new sui generis residential use, with exemptions from minimum space standards, affordable housing requirements, and other key regulations such as the dual aspect rule. 

Importantly, sui generis status ensures that any change of use would require full planning permission, thereby protecting the integrity of the intended residential use and its intended social purpose; albeit a buffer on asset liquidity, it ensures retention where there is genuine need. But it also presents the opportunity for PBYPA to be exempt from the very regulations and requirements that block development and increase costs for renters. 

This classification should draw on precedents established for PBSA and Co-Living as unique uses within sui generis, allowing schemes to operate outside the Nationally Described Space Standards while maintaining robust quality and safety controls through design, guided by planning rules, and in management, ensured by institutional investor ownership. 

3.3.1 What regulations will PBYPA be exempt from?

PBYPA will form a distinct residential use with tailored regulatory exemptions designed to enable efficient, lower cost housing delivery, facilitated by virtue of being classified as a sui generis residential use. 

PBYPA will be permanently exempt from:

• Minimum space requirements, to enable the market to deliver the space that young professionals are willing and able to afford. 
• Affordable housing requirements, to facilitate lower rents via market delivery. 
• Dual aspect requirements, to facilitate greater density.
• The second staircase rule, where a PBYPA development is below a height of 50m. 

These exemptions are not unprecedented. They extend principles already accepted for PBSA, and Co-Living. But, PBYPA is different in that exemptions will go further to achieve the specific aim of high quality, lower cost purpose built living that is affordable to young professionals. The rationale for each exemption is described in greater detail below. 

Overall, the sui generis classification creates a balanced and deliverable model that can scale across UK cities. It combines planning control with flexibility, promotes affordability through existing policy mechanisms, and helps ease demand pressures on the broader private rental market.⁵⁴

Minimum space requirements

Exemption from space standards is already a practice for purpose built living models, but should go further. Although Co-Living and PBSA are exempt from minimum space standards, this is on the basis of them instead providing residents with quality amenity provision on-site, such as gyms, undermining the density delivery and rent saving benefits of smaller space provision. This is something that PBYPA, as an asset class in its own right, would be exempt from to enable the delivery, and choice, of lower rents. PBYPA would place less emphasis on on-site amenities in comparison with Co-Living, instead leveraging its urban context where residents can access local services, gyms, cafés, and social venues. This approach supports higher unit densities, reduces operational costs, and could translate into lower rents for young professionals, all while supporting the local economy. 

Affordable housing obligations

Owing to PBYPA’s single-tenure and purpose-built nature, the asset should be exempt from traditional affordable housing obligations. These exemptions inherently enable lower rents to be achieved through reduced build and operational costs, higher delivery efficiency, and the removal of internal cross-subsidy or complex tenure layering. This ensures that every unit contributes directly to affordability while strengthening overall scheme viability. At the same time, PBYPA can help ease pressure on HMOs and the wider private rental market by freeing up housing stock for families and other groups. By providing stable, well-located homes for young professionals, it supports urban productivity and workforce retention while enabling residents to rebuild financial resilience through savings for deposits, pensions, and other long-term goals.

Dual aspect rule

To further the unique status of PBYPA, there are design threats to the delivery of housing in London that PBYPA should be exempt from as an asset. For schemes like PBYPA, where affordability depends on efficient floorplates for density, mandating dual aspect could cut potential unit numbers. The resulting loss of supply raises build costs per unit and, ultimately, threatens the likelihood of lower rents. PBYPA should therefore be indefinitely exempt from this requirement. 

The second staircase rule

Forthcoming fire-safety rules requiring second staircases in all residential buildings over 18 metres pose a challenge to mid-rise viability, especially for PBYPA. Thus, for this asset, the proportionate threshold of 50 metres, consistent with European comparators, would maintain safety while supporting feasible delivery and thus should be exempt from the 18m threshold.

Conclusion

The UK’s housing crisis is predominantly urban. In cities, supply shortages and an overreliance on limited housing types have pushed rents to record highs. Yet the steady influx of young professionals into urban centres, combined with their stable incomes and long-term demand for rental homes, exposes the clear opportunity and need for a purpose-built housing model designed for them. This new type of housing can divert competition and relieve pressure on the broader urban housing market.

A Purpose-Built Young Professional Accommodation model would fill this gap. It offers an economically viable asset that can be delivered and managed by institutional investors, providing lower rents than Co-Living through higher-density design, targeted regulation exemptions, and reduced amenity costs. By focusing on affordability, efficient layouts, and professional management rather than luxury communal spaces, PBYPA can deliver high-quality, attainable homes for a generation currently priced out of city living.

Policy recommendations

1. Create a new sui generis residential use for PBYPA.
   Planning policy should formally recognise PBYPA as a distinct housing typology, alongside PBSA and Co-Living. This new sui generis use would protect the asset from conversion without new planning permission, provide planning certainty via regulatory exemptions, and establish the regulatory basis for investment at scale.
2. Exempt PBYPA from the Nationally Described Space Standards (NDSS).
   As with PBSA and Co-Living, smaller private units should be permitted where management standards are in place, but without the need for luxury amenity provision. This flexibility allows for higher density, lower rents, and better use of urban land without compromising quality for young professionals.
3. Exempt PBYPA from dual aspect.
   As a distinct asset class, PBYPA should be exempt from dual aspect requirements in order to maximise deliverable density.
4. Exempt PBYPA from the second staircase rule until 50m height has been met.
   PBYPA should be exempt from second staircase requirements in order to maximise deliverable density.
5. Streamline planning, delivery and affordability by exempting PBYPA from affordable housing provision.
   If investors are able to demonstrate that they can offer PBYPA units at a lower rent than the market price, they should be fast tracked for planning approval. But there should be no requirement for PBYPA to deliver affordable housing, given it is a threat to the delivery of affordability being effectively achieved through the market, and owing to the ability of PBYPA to ease pressure on the wider housing market as a planning gain.
6. Amend the National Planning Policy Framework (NPPF) to recognise filtering schemes.
   The Government should acknowledge that specialist, purpose-built rental products such as PBSA and PBYPA help relieve pressure on the wider housing market by providing dedicated homes for defined groups. This would give local authorities a stronger basis for approving such developments within housing targets.
7. Prioritise brownfield regeneration.
   Local authorities should identify underused or derelict urban sites suited to higher-density, managed housing where development opportunities are rich but under utilised.
8. Enable conversions through Permitted Development Rights (PDR).
   Vacant offices and commercial buildings should be able to be repurposed into PBYPA. But, owing to minimum space requirements nationally applied to permitted developments, this is currently not possible. Exempting PBYPA from the regulation applied to permitted developments would help revitalise city centres while adding affordable homes close to employment without minimum space requirements thwarting their delivery.
9. Repurpose Strategic Industrial Land (SIL) where appropriate.
   In London, portions of under-performing SIL could be re-designated for mixed-use regeneration incorporating PBYPA, subject to no net loss of critical employment capacity. This would align housing delivery with urban intensification objectives.

Elections from across the Western world have shown a widening gender gap between men and women. America, Germany, and South Korea have all seen political polarisation along gender lines, with young women moving rapidly leftwards and young men drifting right. Pressures like unaffordable housing and the high cost of living are felt by young men and women alike, but young people’s political and attitudinal responses to those challenges are increasingly diverging by gender.

Polling and focus groups conducted by JL Partners on behalf of Onward and the Konrad Adenauer Foundation shows that this gender divide is also opening up in the UK, with the split being the most pronounced among Generation Z (those aged 16-28). With a nationally representative sample of 5,000 16-40 year olds, our polling shows that young men are increasingly opting for Reform UK while young women are moving towards the Greens.

We also find ideological and wellbeing divides: young women report lower life satisfaction and feel stressed more often compared to men. They also overwhelmingly think society treats them worse than men and are less likely to view immigration and crime as major issues.

The International Gender Divide

As discussed in the introduction, the widening gender divide is part of a broader global trend occurring throughout Western societies. A key example is offered by the 2024 US election. Trump won the support of 49% of men aged 18-29, but only 38% of women in that age group. Whereas Harris won 61% of women aged 18-29, but only 48% of young men.^[i] Elections elsewhere show even wider gender divides opening up.

Figure 1 – 2024 Presidential election vote shares by age and gender^[ii]

For example, in Germany’s 2025 federal election, the far-right AfD secured the largest share of ‘zweitstimme’^[iii] among young men, with 25.2% of those aged 18-24 and 25.6% of 25-34 year olds voting for the party.^[iv] Meanwhile, left wing Die Linke dominated among women in the same age group, winning 37.1% of those aged 18-24 and 21.2% of 25-34 year olds.^[v] Die Linke’s stellar performance among young women was made all the more surprising given that it was polling consistently below the 5% threshold for seats just the month before the elections.^[vi]

Figure 2 – 2025 German federal election vote share of the second vote (zweitstimme) by age and gender^[vii]

The 2025 Portuguese legislative elections also had a large gender gap, with 31% of men aged 18-24 voting for Chega, the insurgent right-wing populist party, compared to only 19% of women in the same age group.^[viii] Women aged 18-24 were more likely to vote for the centre-left socialist party, the left wing/green Livre party, and the far left Left Bloc.

Figure 3 – 2025 Portuguese legislative election vote share by age and gender^[ix]

A similar trend also seems to be emerging in Portugal’s Iberian neighbour, Spain. Recent analysis of polling microdata by El Pais shows Vox, a right-wing populist party, polling as high as 40% among men aged 18-34 while barely reaching 20% with women of the same age group.^[x]

Figure 4 – Percentage intending to vote for Vox at the next election by age and gender^[xi]

Yet none of these quite compare to the extreme gender polarisation seen in the 2025 South Korean presidential election. Called after the impeachment of the previous president, Yoon Suk-Yeol of the right-wing People Power party, for leading an insurrection and amid a massive fertility crisis the 2025 elections saw a huge divide between men and women.^[xii] “Anti-feminist” candidate Lee Jun-Seok and right-wing candidate Kim Moon-Soo garnered 37.2% and 36.9% of the vote respectively among men in their 20s, while women in their 20s overwhelmingly voted for left-of-centre Lee Jae-Myung.^[xiii] As if symbolic of the huge gender rift in Korean politics, Jun-Seok drew controversy after a remark about “sticking chopsticks in women’s genitals” during a TV debate.^[xiv]

Figure 5 – 2025 South Korean presidential election vote share by age and gender^[xv]

While the UK may not yet be quite as polarised along gender lines as South Korea, our polling shows a similar divide opening up among young men and women. This deepening rift of the sexes is an international phenomenon, and could be here to stay.

1. The Partisan Divide

1.1) Headline voting intention^[xvi]

That younger women are moving leftwards and younger men are moving rightwards emerges clearly from our polling. Among young people intending to vote, Reform UK leads among men aged 16-25 with 31% of the vote, yet they are a distant third with women of the same age group. Generation Z women are instead turning to the Green Party, which polls at 25% with women aged 16-25, second only to Labour.

Figure 6 – Headline voting intention by age and gender

The political gender gap^[xvii] narrows in the 26-35 age group, where men and women vote for parties of the left and right in similar numbers, before widening again among those aged 36-40. In this way the gender gap roughly tracks life satisfaction as those in the prime of their life, aged 26-35, report higher life satisfaction than those aged 16-25 and 36-40. The gender gap is widest in the 16-20 age group where 47% of men intend to vote for either Reform UK or the Conservatives, compared to only 25% of women.

1.2) Voting Intention, Gender, and Relationship Status

The political gender divide is wider between single men and single women. 31% of single men intend to vote Reform UK compared to only 26% among men overall. By comparison, 24% of single women intend to vote Green compared to only 18% of women overall. Those who are single are also much less likely to vote for Labour: only 24% of those who are single intend to vote for Labour at the next election.

Figure 7 – Headline voting intention by age, gender, and relationship status

The political gender gap is barely noticeable among those who are married. An identical percentage of married men and married women (63%) intend to vote for either Labour, Lib Dems, or the Greens. Married men and women are also much more likely to vote for Labour — 41% of those who are married intend to vote Labour. While a similar percentage of single women (62%) intend to vote for Labour, Lib Dem, or the Greens only 47% of single men intend to vote for a party on the left.

Figure 8 – Headline voting intention: married men and married women

1.3) Voting Intention, Gender, and Ethnicity

There is particular political and gender polarisation among white British and Irish people compared to those of other ethnicities. While Reform UK lead by 27 points among white British and Irish men aged 16-20, Greens lead with women of the same age and ethnicity. Reform UK and the Greens also outperform among young white British and Irish people compared to those from other ethnic backgrounds, performing particularly well among those aged 16-25.

Figure 9 – Headline voting intention: white British & Irish men and women by age

The gender gap is comparatively narrower on average for those from minority ethnic backgrounds, particularly among those aged 16-25. The gap between white British & Irish women aged 16-25 is 40%, but is only 15% among 16-25 year-olds from other ethnic backgrounds. The Conservatives and Labour also perform better among those from minority ethnic backgrounds, while Reform UK and the Greens perform worse.

Figure 10 – Headline voting intention: men and women from all other ethnic backgrounds by age

1.4) A tale of two generations?

Generation Z (aged 16-28) and Millennials (aged 29-40) are notably different from one another when it comes to their voting intentions. Millennials are more likely to vote for parties closer to the centre (Labour, Lib Dem, Conservatives) while Generation Z are more likely to opt for radical options (the Greens and Reform UK). The political gender gap is also significantly smaller among Millennials than Generation Z, with Millennial men and women voting for parties of the left and the right in similar numbers. However, a closer examination reveals two smaller age groups that are even more distinct from one another than the classic Generation Z-Millennial distinction: ‘Generation Covid’ and ‘Generation Coalition’

Figure 11 – Headline voting intention: Generation Z and Millennials by gender

1.4.1) Generation COVID

Those aged under 18 during the COVID pandemic, which we dub ‘Generation COVID’, are particularly polarised by gender. All aged 16-23, Generation COVID are more likely to vote for Reform UK or the Greens: Reform UK hold a 10 point lead with Generation COVID men, while the Greens are in front among Generation COVID women.

They are also more polarised in general, 47% of Generation COVID men and 45% of Generation COVID women intend to vote for either the Greens or for Reform UK compared with just 33% of men and 33% of women aged 24-40. Generation COVID are also the most likely to think that democracy is completely broken.

Figure 12 – Headline voting intention: Generation COVID by gender

To an extent, this mirrors some of the findings of the Yale Youth Poll which showed that American 18-21 year olds were more likely to vote for the Republicans compared to those only a few years older.^[xviii] Our findings may give some weight to the theory that Gen Z were radicalised through spending a lot of time online during COVID, especially as 43% of this age group said they spent “far too much time on social media”.

1.4.2) Generation Coalition

Standing in stark contrast to Generation COVID, is Generation Coalition. All aged 28-34, this generation turned 18 just before or during the coalition years. This generation are very likely to vote Labour and somewhat more likely to vote Conservative. They are generally more satisfied with life and are more positive about the state of democracy in the UK. 46% of Generation Coalition said they were either “doing well”, “progressing”, “thriving” or “flourishing”, compared with only 33% of Generation COVID.

2. Political Leaders and preferences for Prime Minister

Opinion on political leaders also sharply diverges by gender. For example, 40% of men under 40 hold a positive view of Nigel Farage compared to only 24% of women. More than a third of men aged 16-25 think Farage would make the best Prime Minister when pitted against Badenoch and Starmer. Less than 20% of women in the same age range agree.

Figure 14 – Of the following choices, who do you think would make the better Prime Minister?

Although Reform’s support is concentrated among younger men and the share who say that Farage would make the best Prime Minister declines with age, men aged 26-30 view him more positively than men aged 16-25. 40% of men aged 16-25 have a negative view of Farage compared with only 30% of men aged 26-40. This suggests that there may be a sizable portion of young men who support Reform in spite of their dislike or ambivalence towards Farage.

Figure 15 – Nigel Farage’s favourability among men and women by age

Young women are, overall, much more undecided than men on who would make the best Prime Minister. 37% of women said they didn’t know who would make the best Prime Minister compared to only 20% of men. This was highest in women aged 16-20 with 45% giving a don’t know response. This likely comes down to many simply not knowing enough about the candidates, 17% of women aged 16-20 said that they didn’t know enough about Starmer to form an opinion, rising to 19% for Farage and 51% for Badenoch.

3. The Ideological Divide

3.1) Top 3 concerns

In addition to differences of opinion on which party to vote for, men and women under 40 also differ in their political priorities. When asked to select three issues that most concern them from a given list, women were more likely to pick prices for food and energy bills, housing affordability, and the conflict in Gaza than men. On the other hand, men were more likely to pick taxes on their income, crime & anti-social behaviour, and levels of immigration than women.

Figure 17 – Percentage of men and women selecting x as a top three issue

 Similarly to voting intention, young people aged 16-25 had the biggest gender divides on what issues concerned them the most. While only 22% of women aged 16-25 selected “levels of immigration” as a top three concern, this rose to over a third of young men (37%). 41% of young men aged 21-25 picked levels of immigration as a top three concern, tying with prices for food and energy bills for their most commonly selected top three concern.

Figure 18 – Percentage selecting levels of immigration as a top three issue

For women aged 16-25, the conflict in Gaza is among their top three concerns, ahead of issues like immigration, climate change, and taxes. 31% of women aged 16-25 selected Gaza as one of the three issues they are most concerned about compared to only 22% of men in the same age bracket.

Figure 19 – Percentage selecting the conflict in Gaza as a top three issue

The gender divide in terms of political priorities widens even further amongst those who are single. 37% of single men picked “levels of immigration” as a top three concern compared to only 21% of single women. Only 19% of single women picked crime and anti-social behaviour as a top three concern while 27% of single men did.

3.2) Gender Equality and Fairness

On the state of gender equality in the UK there are major attitudinal divides between young men and women. 46% of young men agree that “Society treats men and women equally well in Britain today”, while only 28% of women agree. Most women instead believe that “Society treats women worse than men in Britain today” (64%). Only 27% of men agree and more think that society treats men worse than women.

Figure 21 – Views on Gender Equality by Gender

The younger you are, the more likely you are to think society does not treat men and women equally, with only 28% of 16-20 year olds holding that view. This number falls to only 17% among 16-20 year old women, with 77% of the view that society treats women worse than men.  

Among men of the same age group, the results are roughly split equally between those who think men are treated worse, women are treated worse, and that both are treated equally. However, younger men are still more likely than older men to say that women are treated worse.

Figure 22 – Views on Gender Equality by Age and Gender

Young men are also more likely than women to think that their parents’ generation had it easier than young people do now. Asked whether it was easier for their generation or their parents’ generation to succeed in life, a majority of men (58%) think it was easier for their parents’ generation to succeed in life,while 26% think it is easier for their generation (net +32%).

In comparison, 50% of women think it was easier for their parents’ generation to succeed in life and 31% think it is easier for their generation (net +19%). This may be a result of respondents comparing themselves to their same-gender parent: men may feel it is harder to measure up to their fathers’ success than women to do to their mothers’, perhaps reflecting women’s expanded career opportunities and pathways.

4. The Wellbeing and Social Media Divides

4.1 – The Wellbeing Divide

Women report feeling stressed and lonely more often than men, and are also less satisfied with life. 40% of women said they felt stressed “very often”, compared to only 26% of men. Younger women feel particularly stressed, with 50% of women aged 16-20 reporting they feel stressed “very often”.

Figure 24 – How frequently respondents report feeling stressed by age and gender

Loneliness is also notably higher among younger women. 53% of women aged 16-25 report feeling lonely very or somewhat often compared to 43% of men aged 16-25. Single women also report feeling lonely more than single men, but the gap narrows slightly. 57% of single women feel lonely very or somewhat often compared to 53% of single men, with the difference at 4% compared to 7% among all men and women.

Figure 25 – How frequently respondents report feeling lonely by age and gender

When asked to rate their life satisfaction, 44% of women say they are suffering, struggling or coping while only 36% of men said the same. Meanwhile, 24% of men say they are progressing, thriving, or flourishing compared to 18% of women.

4.2 – The Social Media Divide

Young women are more likely to say that they spend “far too much time on social media” than men. 39% of women said they spent far too much time on social media compared to only 26% of men. This number rises to 49% among women aged 16-25, with 36% of men in the same age group saying the same.

Figure 27 – Self-reported time spent on social media by age and gender

While both young men and women say they spend either “far too much” or “a bit too much” time on social media, the specific apps that they use are not necessarily evenly balanced by gender. For example, 71% of women use TikTok regularly but this number falls to 60% of men. And TikTok’s gender gap is also notably wider among the 16-25 age group, where 84% of women use TikTok regularly compared to only 67% of men.

Figure 28 – Percentage using TikTok regularly

The inverse is true for Twitter / X, which 46% of young men use regularly compared with just 26% of women. Twitter / X’s gender gap, as well as general usage, increases with age. 56% of men aged 26-35 use Twitter / X regularly compared to only 33% of women in the same age group.

Figure 29 – Percentage using X / Twitter regularly

Instagram and Facebook are also used more by women than men, although Facebook has a sharp drop off among both men and women aged below 30. Meanwhile, Reddit and YouTube are used more by men, with both having relatively smooth age profiles. Threads and Bluesky still struggle to cut through among men and women of all ages.

Conclusion

Like the rest of the Western world, a significant gender divide is emerging in the UK. As Reform builds their lead among Generation Z men, the Greens are increasingly winning over Generation Z women. But while men and women increasingly differ on who has the solutions and what they are, they are united in their call for change. Disillusioned with democracy, dissatisfied with life, and facing falling living standards, Generation Z, and particularly Generation COVID, could represent an existential threat to mainstream political parties if their voting behaviour does not change.

One cause of the gender divide may be that men and women, particularly those in Generation COVID who spent much of their time in the pandemic in digital communities, increasingly inhabit parallel online spaces which reinforce radically different worldviews. At the same time, these are far from being conventional echo chambers; social media algorithms actively promote provocative counter-views, likely further entrenching division through provoking outrage and hardening beliefs, rather than insulating users against opposing ideas.

The antidote to this polarisation may lie in the formula that has made those only a few years older more likely to vote for Labour, the Liberal Democrats, and the Conservatives: prosperity. Those who are wealthier, married, and feel they are doing better in life are more likely to vote for one of the big three mainstream parties. While this might only be a temporary fix, as Reform’s vote share only continues to rise after the age of 35, it represents one of the few remaining roads to recovery for Britain’s traditional parties.

If Generation Z continues to be let down by the political mainstream and fails to reach key life milestones by the age millennials are now, political parties will have to adapt to a more volatile and gender polarised political environment if they are to survive.
