Key Takeaways

  • Andy Burnham, on course to become UK prime minister, has pledged the biggest council housebuilding programme since the post-war period, but has set no firm annual target or total cost.
  • The Centre for Policy Studies argues the inherited £39bn Social and Affordable Homes Programme funds only around 14,300 to 15,500 homes a year, roughly 5 per cent of England's annual housing target.
  • Delivery is constrained by lost council building capacity, construction skills shortages, higher build and borrowing costs, and Housing Revenue Account rules requiring homes to broadly pay their way.
  • Supporters including the National Housing Federation back the ambition, citing close to 1.5 million council homes lost since the 1980s and a comparable number of households on waiting lists.
  • Burnham's plans remain a political pledge, not confirmed government policy, until Labour's leadership process concludes later in July 2026.

Summary

Andy Burnham, the reported incoming UK prime minister, has pledged the biggest council housing programme since the post-war period. Supporters welcome renewed investment in social homes, but analysts including the Centre for Policy Studies question the scale, cost and funding, noting the inherited £39bn scheme may fund only about 15,000 homes a year. His plans remain a pledge, not confirmed policy.

Burnham's council housing pledge meets a reality check

Andy Burnham's pledge to lead "the biggest council housebuilding programme since the post-war period" has pushed council housing back to the centre of British politics. Yet with Mr Burnham still only the reported frontrunner to become prime minister, and his language on scale and cost notably loose, housing professionals are asking a blunt question: how many homes does he actually mean, and who pays for them?

Speaking in late June, the Greater Manchester mayor set out a "housing first" vision, citing Finland's approach and promising to build on vacant public land to hold down costs. The remarks landed as Mr Burnham moved to the brink of Labour's leadership: he secured 322 of 402 Labour MPs' nominations in an early vote, with potential rivals standing aside and the process due to conclude later in the month.

What has Andy Burnham actually promised?

Mr Burnham has framed council housing as central to renewing Britain, invoking the scale of post-war construction, when local authorities completed around 140,000 homes in a single year in the late 1970s. He has not, however, attached a firm annual target, a total cost, or a clear definition of whether "council housing" means homes built directly by councils, delivered through housing associations, or the broader "affordable" category.

That ambiguity matters. Housing analyst Pete Apps has noted that the phrase "the biggest programme since the post-war period" is undefined, and that the numbers behind it vary enormously depending on interpretation. English councils built 10,480 homes in 2024/25, a recent high but a fraction of 1970s output; the long-run average has been closer to 2,000 to 3,000 a year.

  • Whether "council housing" means homes built directly by councils or delivered through housing associations
  • A firm annual target and total cost beyond the inherited £39bn affordable homes programme
  • How councils would rebuild the workforce, land banks and expertise lost since the 1980s
  • Whether Treasury borrowing rules will be loosened to let councils invest at scale

A pledge, not yet a policy

Crucially, none of this is confirmed government policy. Mr Burnham is expected to become prime minister later in July, subject to Labour's leadership process concluding, but until then his housing plans remain a political pledge rather than a costed programme. Much of what he has described builds on commitments already made under Sir Keir Starmer's government rather than on new money he has himself secured.

The funding question: does £39bn stretch far enough?

The existing framework is the government's Social and Affordable Homes Programme, worth £39bn over ten years, with bidding opened in February 2026. Ministers aim to deliver around 300,000 social and affordable homes, at least 60 per cent of them for social rent, equivalent to roughly 180,000 lower-rent homes. Council preferential borrowing rates from the Public Works Loan Board have been extended to March 2027.

Critics argue the sums do not match Mr Burnham's rhetoric. The Centre for Policy Studies calculates that £39bn, spread across a decade, funds between about 14,300 and 15,500 homes a year, some 5 per cent of England's annual housing target. At an average build cost the think tank puts near £251,700 per home, it contends that closing the wider shortfall through social housing alone could cost well over £1 trillion.

Some economists point to alternative funding routes: low-interest public housing bonds on the French model, equity from national banks, or classifying social housing as infrastructure investment. Mr Burnham has reportedly ruled out the infrastructure reclassification that would ease Treasury borrowing rules, which analysts say limits how far councils and associations can gear up new debt while build and borrowing costs remain elevated.

Planning reform, land and the building machine that vanished

Supporters say cheaper public land and planning reform could improve the arithmetic. Mr Burnham has emphasised using surplus state-owned sites, and the government has consulted on changes to the National Planning Policy Framework. But land assembly, remediation and infrastructure still carry heavy costs, and planning capacity in many councils has been hollowed out by years of budget pressure, slowing the pace at which sites can come forward.

There is also the question of who does the building. Mr Apps points out that councils once ran their own building departments, large workforces and in-house expertise, capabilities largely dismantled since the 1980s. Rebuilding them, alongside a construction sector already reporting skills shortages and rising materials and labour costs, cannot happen quickly, and would compete with private housebuilders for the same scarce trades.

Local-authority finances and the Housing Revenue Account

Council finances add a further constraint. Homes held in the ring-fenced Housing Revenue Account must broadly pay for themselves, yet the Centre for Policy Studies argues that average English social rents of £5,942 fall short of the £6,280 it estimates for annual upkeep, with the gap wider in London. If those figures hold, each new low-rent home could add to long-term liabilities rather than easing them.

The traditional engine of new social homes, housing associations cross-subsidising affordable rent with private sales, has also weakened. Falling development margins, building-safety remediation bills and higher interest costs have squeezed the sector, particularly in London, leaving less internal cash to match government grant. That places more weight on public funding precisely as borrowing has become more expensive.

How deep is the demand for social housing?

The case for building rests on need. Britain has lost close to 1.5 million council homes since the 1980s, with a broadly comparable number of households now on social housing waiting lists, according to Inside Housing. Long waits, spiralling temporary accommodation costs and overcrowding all point to acute demand, which supporters say justifies public investment even where individual homes run at an operating loss.

The demand is unevenly spread. In London, where affordability is most acute, waiting lists have lengthened sharply over the past decade, and temporary accommodation is costing councils hundreds of millions of pounds a year. Campaigners argue that every additional social home reduces reliance on costly private rentals and gives families security, though the upfront capital demand is highest in exactly those high-cost areas.

Kate Henderson, chief executive of the National Housing Federation, has called Mr Burnham's focus "absolutely right". Yet the federation has also warned that a request from Homes England for social landlords to "re-profile" their bids could reduce housing starts by around 17,000 by 2029, underlining how fragile delivery remains even under current plans.

The economic prize and the risks

Advocates also stress the economic dividend. A sustained programme could support construction employment, revive apprenticeships and channel investment into left-behind areas, themes central to Mr Burnham's regional pitch. The National Housing Federation and others argue that building at scale trims the housing benefit bill over time and lifts productivity by giving workers stable, affordable homes near employment, though those gains would take years to materialise.

Weighing the revolution against the reality check

For all the enthusiasm, the debate over council housing is really a debate about money, capacity and time. Proponents see a chance to rebuild a public asset stripped away over four decades and to deliver jobs and economic activity across the regions. Sceptics such as the Centre for Policy Studies counter that Britain's real shortage is of homes of all tenures, and that a subsidy-heavy model risks poor value for taxpayers.

Until Mr Burnham sets a firm number, a funding route beyond the inherited £39bn, and a credible plan to rebuild the workforce, the scale of his council housing revolution remains uncertain. Whether it proves a lasting transformation or a costly gamble will depend less on the ambition of the language and more on the arithmetic that follows it.
