Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department will take to support households unable to access Energy Company Obligation 4 before its expiration on 31 March 2026.

Eligibility for the Energy Company Obligation 4 (ECO4) and the Great British Insulation Scheme (GBIS) does not guarantee assistance, the Department cannot direct who receives support. ECO4 and GBIS have already supported an estimated 292,490 households to February 2025, with around 9,000 homes per month in the last quarter. We are committed to meeting fuel poverty and Net Zero targets, and we are currently considering what policy mix will best achieve that, including what role energy company obligations should play post-2026.
