Around 78% of homes started under the 2021-26 AHP were for social rent 

The Greater London Authority (GLA) started 21,001 affordable homes between 2021 and 2026, beating the renegotiated goal of 19,000.

The government’s original 2021-26 target for City Hall’s £4bn Affordable Homes Programme (AHP) was 35,000 starts. This was revised down to 23,900-27,200 in 2023 and again in 2025 to 17,800-19,000 following an increase in inflation and borrowing costs. 

By March 2026, the GLA recorded 14,335 starts. In May, the initial March deadline was extended by up to six months on a case-by-case basis.

Roughly 78% of the homes started between 2021 and 2026 under the AHP were for social rent. Meanwhile, 4,054 affordable homes were completed in this period.

The mayor of London, Sadiq Khan, said: “I know we’ve still got a long way to go to tackle the housing crisis. I’m working closely with the government to agree temporary emergency measures to get stalled sites moving.

”We’ve also secured funding to help build thousands more social and affordable homes over the next decade to ensure we deliver the homes Londoners desperately need, as we build a better London for everyone.”

Bidding for the £11.7bn London Social and Affordable Homes Programme 2026-36 opened in February. City Hall reported last month that it has already issued offers of at least £6bn of funding in the first round of allocations, with 60% of this going to local authorities for council housing.
