Angela Rayner’s target of 300,000 affordable homes through the Social and Affordable Homes Programme would need another £8 billion if ministers want the whole £39 billion pot turned into social rent, according to new Resolution Foundation analysis.
The think tank said shifting the entire programme away from other affordable tenures would still fall short, delivering just under 250,000 homes across the scheme’s life unless extra money is found. It argued that ministers could partly offset the shortfall by steering more Section 106 contributions towards affordable rent and using low-interest National Housing Bank loans to push out more homes.
For landlords, the fresh point is not just that social rent supply needs more funding. It is that the government is now under pressure to redirect subsidy and planning obligations in ways that could change local competition, development cashflow and the shape of new rental supply over the next decade.
Why the affordable housing row matters to landlords
The Resolution Foundation’s Housing Outlook Q3 2026 lands as ministers try to prove they can hit housing targets without blowing up delivery elsewhere. Its core warning is blunt: shifting grant harder towards social rent may be politically attractive, but it reduces the total number of homes unless the Treasury adds more cash.
That matters to private landlords because subsidy choices affect how quickly homes are built, where affordable stock is concentrated and how much pressure stays in the private rented sector. If total delivery remains weak, landlords are unlikely to see much relief on rental demand even if ministers talk more aggressively about social housing expansion.
Section 106 and housing bank pressure could reshape local supply
The think tank said councils could temporarily tilt Section 106 requirements away from social rent and towards affordable rent to keep more schemes moving while private demand stays soft. It also argued that Homes England’s National Housing Bank could add between 3,700 and 6,100 homes a year, depending on tenure mix.
For landlords and investors, that is the more immediate commercial signal. If local authorities and developers get more room to keep schemes viable, more mixed-tenure stock may come through in areas where outright sales remain patchy. But if the policy debate drifts into a simple social-rent-versus-private-rent argument, the bigger supply problem remains unresolved.
This follows Landlord Knowledge’s report on Scottish housebuilding dropping to a decade low, which highlighted how weak delivery keeps pressure on the wider rental market. The latest Resolution Foundation warning points to the same basic problem in England: ministers can reshuffle tenure targets, but they still need enough money and enough viable schemes to get homes built.
Landlord Knowledge has also tracked how shrinking private stock is feeding the same imbalance, most recently in our coverage of landlords selling three homes for every one bought. If affordable output does not accelerate materially, that loss of private rented supply becomes even harder for the market to absorb.
What this means for landlords
- If you invest in supply-constrained areas: do not assume a bigger social-rent push will quickly ease tenant demand in the private rented sector.
- Watch for: local planning negotiations over Section 106, as tenure mix changes can affect nearby competition and scheme viability.
- If you buy from developers: mixed-tenure projects may become more common if councils and Homes England lean harder on affordable-rent and loan-backed models.
- Bottom line: the argument has shifted from whether more affordable housing is needed to who pays for it and which tenure gets priority.
Editor’s view
Landlords should ignore the culture-war framing and watch the funding mechanics instead. If ministers cannot turn housing targets into viable schemes, private landlords will still be left carrying demand that public policy failed to house.
