Housing: Insulation
The question
To ask the Secretary of State for Energy Security and Net Zero, how many homes had spray foam insulation installed under (a) the Green Homes Grant, (b) the ECO4 scheme and (c) the Great British Insulation Scheme; and of those, how many have been identified as having been incorrectly or inappropriately installed.
Answered by Martin McCluskey
The Department publishes statistics on measures installed under the Green Homes Grant, ECO4 and the Great British Insulation Scheme, but does not hold specific data on properties with spray foam insulation.
We are aware of a small number of cases where spray foam has caused issues and are taking action. Where poorly installed under government schemes, customers can use TrustMark’s dispute resolution process or their guarantee. For work outside these schemes, homeowners should seek remediation via their installer, relevant quality mark, or guarantee provider.
