Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent assessment he has made of the adequacy of the (a) oversight and (b) remedial mechanisms of the (i) ECO4 scheme and (ii) Cavity Insulation Guarantee Agency.

Since 2019, installations under Government backed energy efficiency schemes, including ECO4, have been required to be carried out by TrustMark registered publicly available specification (PAS2030) certified installers alongside an insurance backed guarantee. Consumers have a route to redress, with remedial work arranged through the original installer and oversight from the relevant scheme provider for quality and auditing, or through the guarantee if installers have ceased to trade.

Cavity Insulation Guarantee Agency (CIGA) is a non-profit organisation that provides guarantee certificates for cavity wall insulation measures. The Department has no oversight of CIGA’s business activities, including the number of certificates issued and/or recalled for remediation.
