The Mayor of London, Sadiq Khan, signed a decision on Wednesday 2 April 2025 approving the receipt and expenditure of £53,470,024 of Warm Homes: Local Grant funding from the Department for Energy Security and Net Zero. The decision, reference MD3366, was published on Thursday 3 April 2025 and sits within the Greater London Authority's Good Growth directorate1.
The funding was secured by the Greater London Authority through the Warm Homes Local Grant competition, for delivery in London between 2025 and 2028. According to the decision document, the money "will enable energy inefficient improvements to homes and low carbon heating upgrades for low-income households in energy-inefficient homes"1.
The decision records that the Mayor "is committed to making London a net zero carbon city by 2030, while ensuring that the most disadvantaged are supported, particularly by tackling fuel poverty"1. The decision seeks formal approval to accept and allocate the funding1.
"That the Mayor approves receipt and expenditure of £53,470,024 of Warm Homes Local Grant funding from the Department for Energy Security and Net Zero."
The decision document lists the decision type as Mayor and the reference code as MD3366. It does not set out a breakdown of how the £53,470,024 will be divided between energy efficiency measures and low carbon heating, nor how many households are expected to be reached. Those figures have not been reported in the decision page1.
Why it matters for households
The Warm Homes Local Grant is one of the routes through which households on lower incomes can access funding for insulation and heating upgrades, delivered by councils and other local bodies rather than claimed directly by residents. The approval means the Greater London Authority can now accept and allocate its share of the national scheme for the 2025 to 2028 period1.
For a household, the practical effect is that the money is held and distributed at London level rather than nationally, so eligibility, the measures available and the application route are set by the local delivery arrangements. The decision document does not describe those arrangements, the qualifying benefits or the income limits, and none of that detail appears on the page1. Households outside London are covered by separate allocations of the same scheme, which are not addressed in this decision.
The funding is aimed at energy-inefficient homes occupied by low-income households, which is the group least able to pay for insulation or a heating replacement themselves. Improving the fabric of a home reduces the energy needed to keep it warm, which is the part of a household's energy position that does not depend on prices or tariffs. The decision document does not quantify the expected savings for any household1.
What happens next
The decision was signed on 2 April 2025 and published on 3 April 2025, with delivery in London running between 2025 and 20281. No further dates, including when households will be able to apply or which boroughs will deliver first, are given in the decision page1.
