PARLIAMENTARY WRITTEN QUESTION
(13 November 2025)

To ask the Secretary of State for Energy Security and Net Zero, what steps he is taking to ensure that (a) homes retrofitted under the Eco4 scheme are inspected and (b) any (i) substandard and (ii) unsafe work is fully remediated.

Asked by:
Luke Taylor (Liberal Democrat)

Government is offering free inspections of all properties where external wall insulation was fitted under ECO4. The focus is on this measure as audits highlighted particular issues with external wall insulation under the scheme. Ofgem will contact every household with external wall insulation that has not yet been audited.

Remediation is already taking place to address substandard and unsafe work, and over half of the issues identified to date have been fixed. Trustmark, certification bodies and installation businesses are working hard to resolve these issues. They will be rectified at no cost to the consumer.
