A recent report backed by a cross-sector coalition, including notable housebuilder Grainger and influential figures such as RIBA president Chris Williamson, recommends that affordable housing values in Section 106 agreements be fixed at the planning stage to improve market efficiency. The report, titled Making Social Rent Homes Viable, highlights dysfunction within the current Section 106 process where housing associations, funded by grants, compete against each other to purchase affordable homes from developers, resulting in inflated prices and inefficiencies. The group proposes that local planning authorities should mandate the value of affordable housing through an agreed formula at the planning application stage, allowing developers to have clarity on financial expectations and base land purchases accordingly. The report suggests indexing these values to inflation based on the consumer price index to maintain fairness over time.
Crucially, the report calls for substantial government subsidy—£18.8 billion annually—to support the building of 90,000 social rented homes each year and explores innovative funding models to realise this ambition. Among these is a system of social housing tax credits modelled after the United States' Low Income Housing Tax Credit (LIHTC) programme, which has funded over four million affordable rental homes since 1986. Under this proposal, companies would pay ten years’ worth of corporation tax upfront to receive a discount, raising government capital without increasing borrowing. The resulting tax receipts would be allocated to Homes England, which would then distribute funds to social landlords for homebuilding. The report argues this approach is “largely self-funding” in the short to medium term, given the projected savings to the Treasury and local council budgets alongside economic activity stimulated in the construction sector.
While the LIHTC programme has been successful in the US, the report acknowledges concerns raised by UK sector figures suggesting that the lack of affordability in perpetuity under the US model could hinder adoption in the UK context. The paper also touches on other proposals, including 'flex rents' linked to household incomes, recapitalising housing association balance sheets, and reforming or abolishing Right to Buy, which many see as diminishing social housing stock. Helen Gordon, chief executive of Grainger, emphasised that despite social rent homes not being the company’s core business, their delivery is vital to a housing strategy that encompasses all tenures to meet diverse societal needs. She described the report as a constructive step towards evidence-based solutions that make social rent housing viable in today's market.
In the broader context of social housing policy, the UK government is also focusing on decarbonisation and energy efficiency as integral to its housing strategy. The National Housing Federation has highlighted that social rented homes are a significant target for carbon reduction efforts, given the environmental impact of England's housing stock. Current initiatives include VAT reliefs for specific energy-saving installations and a proposed £3.8 billion Social Housing Decarbonisation Fund over ten years, with a recent push to allocate up to £160 million to registered providers. Additionally, the government is consulting on setting a spend exemption threshold to improve energy efficiency in social housing, intended to benefit up to 1.8 million homes by balancing upgrade costs with providers’ financial capacities.
Tax reliefs have also been extended to housing co-operatives, an often overlooked sector in affordable housing. Recent government measures provide relief from the Annual Tax on Enveloped Dwellings and Stamp Duty Land Tax for non-publicly funded cooperatives, supporting their growth and sustainability as alternative affordable housing forms.
The overall financial landscape for social housing is also influenced by government budget decisions. Planned increases to social rents in England by Consumer Price Index inflation plus an additional 1% provide long-term investment certainty for social housing providers, facilitating the construction of many new homes. Meanwhile, reform of Right to Buy discounts and the ability for councils to retain all receipts from sales aim to protect and expand the existing social housing stock. Social welfare adjustments, such as uprating working-age benefits by CPI, also aim to help low-income tenants manage rising housing costs.
Together, these initiatives and proposals represent a multifaceted approach to addressing the chronic shortages and quality issues within the UK’s social housing sector, combining market reforms, innovative financing, government investment, and sustainability goals.
