As the first step towards the Warm Homes Plan, the Government has committed an initial £3.4 billion over the next 3 years towards heat decarbonisation and household energy efficiency, with £1 billion of this allocated to 2025/2026. The current iteration of the scheme, ECO4, runs from 2022 - 2026 with an increased value of £4 billion to accelerate our efforts to improve homes to meet Fuel Poverty targets.

Government does not specify which types of measures should be installed in any particular property, only that the installations should be carried out by TrustMark registered installers in accordance with the relevant standards and consumer protection requirements.
