Property experts question whether PM Andy Burnham's mission to build the most council homes since the postwar period can survive contact with reality, as the UK housebuilding industry faces turmoil. Labour's target of 1.5mn new homes has yielded fewer completions than under the Conservatives, while UK-listed housebuilders have issued eight profit warnings during the first half of 2026, the highest first-half total since the pandemic.

Attention focuses on Vistry, the lossmaking housebuilder whose value has fallen £1.2bn this year. Former infrastructure adviser Nick Williams argued in a private memo that Vistry should be nationalised as a "delivery body" for new towns, citing the British Steel precedent. The government denies considering nationalisation, but monitors Vistry closely given its role in public schemes. Vistry's enterprise value stands at £1.1bn, with shares down 56% year-to-date.

Sector challenges include a demand slump from affordability constraints and rising costs. The Home Building Federation estimates developers face an extra £76,000 in new costs per home since 2020, equivalent to a fifth of the average £365,000 new home value. Compliance with the Building Safety Act and green rules adds months to projects.

Burnham plans to seize public-sector brownfield land, but analysis by Together shows capacity of only 187,000 to 207,000 homes — far short of Labour's 300,000 social and affordable homes target. "Whether this pledge reaches your community is close to a postcode lottery," said Ryan Etchells.
