Andy Burnham's first instruction as prime minister — "to end rough sleeping in our country" — carries the weight of personal credibility. He made the same pledge on his first day as mayor of Greater Manchester in 2017, spent political capital on it, and drove rough sleeping numbers down every year from 2018 to 2021 through two programmes: A Bed Every Night, which expanded emergency accommodation beyond statutory "priority need" categories, and Housing First, which places the most entrenched rough sleepers directly into stable housing rather than hostels. Both showed results. Both have limits. The national picture is brutal. England's autumn 2025 rough sleeping snapshot hit a record 4,793 — exceeding the 2017 peak of 4,751 and marking the fourth consecutive annual increase. Government spending on homelessness has more than doubled in five years, yet outcomes have worsened. IPPR North, in a report co-authored with Crisis, projects homelessness could rise 25% to over 230,000 people by 2030 without radical intervention. The money is being spent; it is being spent on the wrong things — primarily expensive, sub-standard temporary accommodation that traps families rather than transitioning them. The Children's Commissioner found 520 families had been living in B&Bs for over a year. Burnham's Manchester model worked in part because he made it a visible political priority, forcing cross-borough data sharing and agency collaboration. Dr Maya Singer Hobbs of IPPR North credits the expenditure of political capital: "People working in the sector told us that made it easier because they knew exactly what he wanted." But even in Manchester, post-pandemic numbers have crept back up, and A Bed Every Night drew criticism — the offer could be a sleeping bag on a hostel floor, with little capacity to move people forward. The structural argument for optimism is real but narrow. As mayor, Burnham had no control over welfare policy, the Home Office's 42-day "move-on" period for asylum seekers, or Ministry of Justice support for prison leavers — all major drivers of homelessness. As prime minister, he holds those levers. The question is whether he can coordinate national prevention (welfare rates, immigration policy, tenancy law) with hyper-local frontline delivery, what Singer Hobbs calls "the eternal balance of any kind of devolution." Scotland provides the cautionary tale. Holyrood's homelessness legislation is lauded as among the world's most progressive — it abolished the concept of "priority need" entirely. But it has failed to deliver because of a catastrophic mismatch between ambitious legal rights and the practical resources required to fulfil them. Most Scottish councils already run Housing First. Rough sleeping has still risen since lockdown. Campaigners blame lost momentum after Covid and a failure of long-term government oversight. The binding constraint is housing supply, and here the record is grim. Burnham has promised "the biggest council housebuilding programme since the postwar period." His predecessor Keir Starmer pledged 1.5 million homes over five years and stalled against high interest rates, rising construction costs, and Brexit's impact on the construction labour force. Innovative local approaches exist — Wigan leasing long-term empty homes from private landlords, Waltham Forest repurposing council buildings — but these are patches on a system that needs structural expansion. Without enough homes at the end of the chain, temporary accommodation remains permanent by default. The Vagrancy Act repeal on 29 June — ending two centuries of criminalising people for not having a home — was symbolically welcome and practically irrelevant. Burnham's challenge is the inverse: converting his proven local instincts and genuine political commitment into a national delivery machine, against the same housing arithmetic that has defeated every predecessor who tried. Tony Blair came close in the early 2000s before progress unravelled under successive Conservative governments. The difference this time is that Burnham has both the personal track record and the national levers. Whether he has the housing supply is another question entirely.
