The UK already has lots of social housing

This may surprise people who hear constantly that social housing has been gutted, but by international standards the UK has a large social housing sector. Around 17–18% of the UK's total housing stock is social rental — more than double the OECD average of 7%. Among comparable countries, only the Netherlands, Austria and Denmark have a larger share.

And yet the UK has one of the worst housing crises in the developed world. England has just 434 homes per 1,000 people, compared to 590 in France, 587 in Italy, and an OECD average of 487. Britain is missing an estimated 4.3 million homes compared to the average European country, according to Centre for Cities research.

The UK does not have a social housing problem. It has a housing problem. The total number of homes — of all types — is far too low. Countries with more affordable housing than the UK do not necessarily have more social housing. They just have more homes.

The waiting list is a symptom, not the diagnosis

It is tempting to look at Glasgow's social housing waiting list — over 14,000 households — and conclude that the answer is simply more social housing. But that misreads the evidence.

The reason so many people are on waiting lists is that market-rate housing has become unaffordable. Rents in Greater Glasgow have risen 75% since 2010. House prices have risen 70% since 2015. People who a generation ago would have rented or bought privately can no longer afford to, so they turn to social housing as the only option left. The waiting list is not evidence of insufficient social housing. It is evidence of insufficient housing, full stop.

Build enough homes to bring market-rate rents and prices back to affordable levels, and the pressure on social housing eases dramatically — not because social housing becomes less important, but because fewer people are forced to rely on it. Read more about Glasgow's housing crisis →

The scale of the gap is beyond what public money can fill

Scotland is estimated to be short by around 250,000 homes. If the government were to close that gap entirely through social housing, at an average cost of £195,000 per home — the Scottish Federation of Housing Associations' 2025 figure, with some specialist or rural homes costing up to £300,000 — the bill would be approximately £49 billion.

The Scottish Government's annual budget for the Affordable Housing Supply Programme is around £600 million — and falling. In 2024/25, the budget was cut by £163 million, a 22% real-terms reduction. At current funding levels, it would take around 80 years to close the gap through public spending alone. And that assumes no further growth in demand, no construction cost inflation, and no further cuts — none of which is realistic.

Centre for Cities research makes the point even more starkly at UK level: Britain has a backlog of 4.3 million missing homes compared to the European average. The idea that public funding alone can close a gap of this size is not a serious policy position. It is a way of sounding radical while guaranteeing that nothing gets built.

Private development costs the taxpayer nothing

Here is what makes the "only social housing" position so damaging. There is another way to build homes — one that costs the public nothing.

Private developers build homes using their own capital. They take on the financial risk. They pay for planning applications, environmental assessments, Section 75 contributions, and affordable housing obligations. And when the homes are complete, the public benefits again: stamp duty on sales, council tax in perpetuity, VAT on construction, corporation tax on profits, income tax and National Insurance from construction workers.

Private housebuilding does not drain the public purse. It fills it. Every private home built is a home the government did not have to pay for — and a household that no longer needs social housing, freeing up a place on the waiting list for someone who does.

Opposing private development does not produce more social homes. It just produces fewer homes overall — and longer waiting lists for the people who need social housing most.

Planning reform helps social housing too

The planning system is not just a barrier for private developers. It is a barrier for everyone who wants to build homes — including councils and housing associations.

Scotland's Housing Secretary Màiri McAllan acknowledged in March 2026 that the planning system is acting as a "hindrance" to housebuilding, and announced a new national agency — More Homes Scotland — specifically to clear the backlogs that have been slowing affordable housing delivery. Edinburgh City Council announced in 2024 that it did not expect to approve any new affordable homes for at least a year, due to planning and funding constraints. The council's own system was blocking the council's own housing.

Housing associations face the same discretionary planning process, the same regulatory costs, and the same community objections as any other developer. The Home Builders Federation found that 80% of SME builders identified planning-related delays in affordable housing delivery as a barrier to growth. Homes for Scotland's data confirms that 22% of the affordable homes that have stalled in Scotland are on mixed-tenure sites where private and social housing are delivered together — when the planning system blocks one, it blocks both.

The fastest way to increase social housing delivery is not to oppose private development. It is to fix the planning system that constrains all development. Reform the rules, and you make it easier to build homes of every type — social, mid-market, and private. Read our demands for reform →
