Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what the minimum improvement requirements are for homes to be eligible for (a) ECO3 and (b) ECO4.

ECO3 ended on 31 March 2022, and ECO4 will run until 31 March 2026.

Under ECO3, householders needed to qualify by being in receipt of eligible benefits. Minimum improvement to properties was not a requirement.

ECO4 is focused on providing support to low-income and vulnerable households living in the least energy efficient properties. Under ECO4, there is a minimum requirement for energy suppliers to improve homes in an EPC band F or G to at least a band D and band D or E homes to at least a band C.
