Cavity Insulation Guarantee Agency and Energy Company Obligation: Wales
The question
To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the cost of remedial work due to be carried out in properties in Wales as a result of work undertaken through the (a) ECO4 scheme and (b) Cavity Insulation Guarantee Agency.
Answered by Miatta Fahnbulleh
Remediation costs can differ significantly from one property to another. All insulation under ECO4 must be installed by a TrustMark-registered installer, and covered by a TrustMark approved 25 year guarantee. The government has previously published guidance for consumers who suspect that they may have faulty cavity wall insulation installed in their home outlining the routes to redress under these circumstances. CIGA is a non-profit organisation that issues guarantee certificates for cavity wall insulation installations. DESNZ does not have oversight of CIGA’s business activities, or the number of certificates issued by it, or where these have been called upon for remediation.
