Four in five social housing homes now have an EPC rating of C or above, according to the latest Sustainability for Housing (SfH) Annual Review, highlighting continued progress in energy efficiency across the sector.

The report, which analysed data from 104 housing providers managing more than two million homes, found that 80% of properties now achieve EPC C or better. Housing associations are also delivering increasingly energy-efficient new homes, with EPC A-rated properties accounting for 13.4% of new-build portfolios in 2025, up from 9.4% a year earlier.

The review also revealed that reporting providers delivered 50,000 new homes during 2024/25, with social rent accounting for the largest proportion of new housing at 34%, followed by affordable rent (25%) and shared ownership (23%).

Piers Williamson, Chair of Sustainability for Housing, said: “For a second year in a row, this year’s report highlights the resilience of the social housing sector as it continues to cut through the continued political noise and prove that sustainability remains a central part of the housing agenda.”

Despite the positive progress, the report highlighted areas of concern. The average proportion of housing stock affected by damp and mould increased from 7% in 2023/24 to almost 10% in 2024/25, underlining the continuing challenges facing providers.
