Chancellor Rachel Reeves has unveiled what she describes as the largest investment in affordable and social housing in a generation: a £39 billion funding plan aimed at addressing the UK’s housing crisis. Set across a ten-year period, the newly announced Affordable Homes Programme is a central part of the government’s strategy to build 1.5 million homes by the end of this Parliament.
The headlines are eye-catching: billions committed, the promise of long-term planning security for providers, and a clear signal that housing is back on the national agenda. But as with many large-scale policy announcements, it raises just as many questions as it does hopes. What will this money actually deliver in the near term? Can it tackle the deep-rooted issues that have plagued the social housing sector for decades? And will this be enough to meet the ever-growing demand?
To start with, the funding model itself is important. The programme will begin with an estimated £3 billion a year in grant funding, increasing gradually to around £4.5 billion annually by 2035. This is not an overnight injection of money, but rather a phased, back-loaded approach designed to offer consistency over time. For local authorities, housing associations and developers, this long-term visibility is welcome. It means they can begin to plan projects with more confidence, knowing there is some certainty in government support over the next decade.
However, this gradual approach has raised concerns within the housing sector. The existing Affordable Homes Programme is due to expire in 2026/27. Without transitional funding or a more immediate boost, there is a risk of a delivery gap. Projects that are in the pipeline now may stall, and momentum could be lost in the crucial early years of this administration.
One of the most frequently asked questions is whether the 1.5 million homes target is actually achievable. The ambition is bold, but it comes against a challenging backdrop. The sector is still recovering from years of underinvestment, planning delays, labour shortages, and supply chain disruptions. Furthermore, while the 1.5 million figure covers all housing types, there is a real concern that too few of these homes will be for social rent, the tenure most urgently needed.
In recent years, the number of new homes built for social rent in England has been strikingly low. In 2023, only around 6,500 such homes were delivered. This falls far short of what many organisations, from Shelter to the Chartered Institute of Housing, argue is needed. Without a significant portion of the new homes being genuinely affordable to those on the lowest incomes, it is difficult to see how this programme can fully address the scale of the housing crisis.
Beyond new builds, the announcement has so far been relatively silent on the issue of existing stock. Many social landlords are grappling with ageing housing, issues of disrepair, and a growing backlog of maintenance. Post-Grenfell, concerns over building safety, damp, and mould have pushed housing standards into the spotlight. While investment in new homes is crucial, it must not come at the expense of maintaining and upgrading the homes that people already live in.
There is also the wider social and economic value of social housing to consider. Research consistently shows that access to safe, affordable housing improves health outcomes, supports employment, reduces welfare spending, and enhances educational attainment. In that context, this investment isn’t just about housing, it’s about public health, opportunity, and community stability. In areas where regeneration is desperately needed, housing can be the catalyst for broader social change.
Of course, all of this sits within the wider fiscal framework. Reeves’s housing investment is part of a broader £113 billion capital spending commitment. While this has been presented as fiscally responsible, some analysts have raised concerns about the sustainability of such spending, especially if economic growth underperforms or other departments require urgent funding. Will housing remain a political priority if pressures mount elsewhere, such as in health or defence?
Nevertheless, there is no denying that this is a significant moment for the housing sector. After years of short-termism and piecemeal funding, the commitment to a 10-year plan provides a level of clarity that has been sorely lacking. It recognises that housing delivery is not instant, that land must be acquired, planning permission secured, partnerships developed, and communities engaged. The very structure of this funding model suggests an understanding that long-term issues need long-term solutions.
Housing providers will be watching closely over the coming months. The next steps will be crucial: how the money is distributed, what conditions are attached, and how delivery is monitored. Will smaller housing associations and local authorities be supported to play their part, or will funding favour large-scale developers? Will there be a focus on place-based regeneration, or simply volume?
Ultimately, this £39 billion announcement is a clear signal that housing is firmly back on the agenda. It is, in many ways, a win for those who have long campaigned for greater investment in affordable homes. But whether this becomes a turning point or just another headline will depend entirely on execution. The ambition is welcome. The delivery, as ever, is where the real challenge lies.
