In the long, familiar cycle of UK housing debates, the Homes for People We Need report Making Social Rent Homes Viable feels different — not because it repeats the same problem statements, but because it quantifies them in a rigorous, financially grounded way that policymakers rarely face head-on. This isn’t another call for more homes; it is an unflinching accounting of what public subsidy and systemic reform would actually need to look like to deliver the social rent homes the country claims to want.
The headline figure is stark: to build 90,000 social rent homes per year in England, the report estimates a viability gap requiring around £18.83 billion in subsidy annually, even assuming free land BUT excluding cross-subsidy from private development. To put that in context, current government funding through the Affordable Homes Programme AT £3.9bn a year for 10 Years and associated mechanisms is projected to fill only around 20 % of that requirement.
This isn’t a marginal shortfall — it’s a structural deficit that lies at the heart of why delivery falls so far short of targets. In fact the first year of the new Government’s affordable housing programme represents a real terms cut.
The report also sheds light on the scale of the existing crisis. While political commitments routinely cite 90,000 social rent homes per year as an aspirational benchmark, actual recent performance has been an order of magnitude lower. Official figures show affordable housing completions for social rent in the year to March 2024 at just over 10,000 units, against a backdrop of chronic undersupply. The contrast between ambition and reality is not academic — it reflects the grinding mismatch between fiscal frameworks and real-world development economics. The land value capture thesis that the private sector can pay for everything needed is dead and well buried.
Perhaps most importantly, the report draws attention to how housing policy has been shaped by accounting conventions that treat social rent as a “drain” on public finances, rather than a long-term investment. In practice, the capital value of social rent homes is significantly lower than development costs, and low rental incomes simply cannot cover these costs over time and therefore requires substantial public subsidy to bridge that gap.
Viewed through this lens, longstanding emphasis on high-level housing targets (e.g., total homes per year) seems out of step with the fundamental economics of the supply challenge. Without a clear strategy to fund social rent at scale, including sustained subsidy and innovative funding mechanisms such as indexed bonds or tax credits, delivery will continue to fall miles below need.
The broader social impact of this shortfall cannot be ignored. With 179,000 familes in temporary accomodation costing LAs £2.8bn a year and rising an unsustainable housing benefits bill and over a million households on social housing waiting list and demand far outstripping supply, the country’s housing system is under tremendous pressure. Independent estimates that social rent homes are essential to tackle both homelessness and housing insecurity highlight a disconnect: the homes that would most effectively alleviate acute need are exactly those that are least financially viable under current policy and funding frameworks.
Where the Making Social Rent Homes Viable report is most valuable is not in diagnosing a familiar problem, but in framing it as a solvable financial challenge — if the political will exists to confront it. Its analysis makes plain that incremental funding increases won’t suffice; we need a clear, long-term fiscal strategy that accepts subsidy as part of the solution, not an embarrassment to be minimised. How policymakers respond to that challenge will determine whether England’s social housing shortfall persists as a chronic policy failure or becomes a resolvable investment priority.
