Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how much total funding the Government has allocated to (a) ECO3 and (b) ECO4.

The ECO scheme is an energy efficiency scheme that places a requirement on larger energy suppliers to deliver energy efficiency and heating measures to people’s homes. Under ECO3, which ran from December 2018 to March 2022, £8.547 billion in lifetime savings was achieved. ECO4 began in April 2022, and will run until March 2026. ECO4 has a target of £224.3 million in annual bill savings over the life of the scheme. The impact assessment for ECO4 moved to annual, rather than lifetime, bill savings due to changes in how ECO projects are scored.
