The Chancellor’s Autumn Statement in 2022 announced that £6 billion would be made available in 2026-28 to improve the energy efficiency of existing homes and progress the transition to sustainable energy. On 18 December some details were provided on how this amount will be allocated. These do not appear to be final decisions as in some cases allocations are still subject to business case approval and value-for-money assessment.

The proposals include allocations to the following schemes:

• The Boiler Upgrade Scheme allocated a further £1.5 billion, to support families in England and Wales move away from gas to energy efficient, low-carbon heat pumps.
• A new £400 million energy efficiency grant, launching in 2025, for households in England to make changes such as bigger radiators or better insulation.
• A new local authority retrofit scheme, allocated £500 million to support up to 60,000 low-income and cold homes, including those off the gas grid, with measures such as insulation.
• The Social Housing Decarbonisation Fund, allocated £1.25 billion to support up to 140,000 social homes to be insulated or retrofitted, improving energy performance and lowering bills.
• The Green Heat Network Fund, allocated £485 million to help up to 60,000 homes and buildings access affordable, low carbon heating through new heat networks, reducing use of fossil fuels and providing more reliable heating.
• The Heat Network Efficiency Scheme allocated £45 million to improve around 100 existing heat networks, in a move that will reduce bills and improve reliability.
• The Industrial Energy Transformation Fund, allocated £225 million, will continue to help businesses transition to a low-carbon future.
