The average house price in England stood at an estimated £300,000 in 2025, almost eight times the average annual earnings of a full-time employee, according to BBC News and Office for National Statistics data published on 16 July 2026.

That ratio frames the policy challenge facing Andy Burnham, who was set to become UK prime minister after the vast majority of Labour MPs nominated him to replace Sir Keir Starmer on 19 June 2026. Burnham had tried and failed twice before to reach Downing Street. His third bid secured the parliamentary party's backing, and he has since made his first major policy speech since launching his campaign.

BBC Verify has examined the scale of the UK housing crisis in relation to Burnham's record and policy proposals, a scrutiny that cuts to the heart of his credibility on an issue likely to define his early premiership.

Burnham is credited with overseeing a building boom in Manchester during his tenure as mayor of the Greater Manchester Combined Authority, the body that governs transport, housing and economic strategy across the city-region's ten boroughs. Greater Manchester has published a comprehensive plan to build new homes and connect communities to new infrastructure under the banner of "turning the tide on the housing crisis." Burnham stated the city-region is ready to deliver 75,000 new homes during the current parliament, a pledge made in July 2024 alongside the unveiling of a UK-first landlord charter for Greater Manchester.

His "new deal for renters," outlined in June 2023, takes a place-based approach aiming to bring all rented homes up to standard, with a target covering 30,000 social rented homes. In November 2025, Greater Manchester revealed an £11.7 million plan to bring long-term empty homes back into use and reduce reliance on temporary accommodation. Burnham has also spoken publicly about reforming stamp duty and council tax.

One option identified for Burnham to increase social housing supply would be to direct a £39 billion, 10-year investment package entirely toward building homes for rent by councils and housing associations, rather than using part of it to subsidise affordable homes for purchase. That choice would mark a departure from the affordable-homeownership models favoured under recent administrations, tilting the balance decisively toward social rent.

The national picture Burnham inherits is stark. Britain had a backlog of 4.3 million homes missing from the national housing market, according to the Centre for Cities. The UK government has set an ambition of 300,000 new homes per year for England; around 233,000 were supplied, falling short. Quarterly housing starts in England have dropped significantly since late 2023 and remain below historic levels, the Joseph Rowntree Foundation reported in April 2026.

The Starmer government introduced planning reforms for England that included changing rules on green belt development — the protected land around towns and cities designed to prevent urban sprawl — to increase the area where homes can be built. Analysts said the reforms should help increase housing construction in the long term. But delivery faces entrenched headwinds. Private housing developers cited a shortage of skilled labourers from Europe since Brexit as a barrier to housing delivery, alongside a jump in construction material costs in the wake of the pandemic and the Russian invasion of Ukraine. Some analysts argue that government environmental and safety regulation is holding back housing construction in England.

What Burnham's record reveals

The Greater Manchester approach offers a test case for several of the levers a Burnham premiership might pull nationally. The city-region's strategy combines direct supply targets, regulatory innovation through the landlord charter, and targeted funding to bring empty homes back into use. Whether those tools, effective at combined-authority scale, can be translated into a national delivery programme is the central question.

The £39 billion investment package option signals the scale of fiscal ambition under discussion. Directing it entirely toward social rent rather than shared ownership or other subsidised purchase models would represent a clear ideological choice, prioritising tenure security and council and housing association delivery over pathways to ownership. That aligns with Burnham's Greater Manchester emphasis on social rented homes and renter protections, but it would place him at odds with the cross-party consensus that has treated homeownership as the default tenure of political aspiration.

The delivery gap

The structural barriers developers cite — labour shortages, material cost inflation, regulatory burden — are largely outside the control of any single government. Planning reform addresses the permissions pipeline, not the construction capacity that actually delivers homes. The gap between the 233,000 homes supplied and the 300,000 annual ambition illustrates how far policy intent and built output diverge.

For Burnham, the housing record he built in Greater Manchester is both an asset and a benchmark. His mayoral tenure shows delivery at city-region scale. Translating that to a national programme of 300,000 homes a year, against the headwinds of a post-Brexit labour market, elevated material costs, and a 4.3 million-home backlog, is a test of a different order entirely.
