The question

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 14 February 2025 to Question 29262 on Insulation: Housing, if he will launch an investigation into homes that had spray foam installed under the Green Grant Scheme.

Answered by Miatta Fahnbulleh

The Government recognises that the system of quality assurance and consumer redress that we inherited needs reform. This work is already underway, with the existing system being tightened, but we will set out plans for root and branch reform as part of the Warm Homes Plan.

Under the Green Home Grant Voucher Scheme (GHGVS) the previous Government did not specify which types of insulation should be installed in any particular property, only that the installations should be carried out by TrustMark registered installers in accordance with the relevant standards and consumer protection requirements.

If the installation has met the standards required in the GHGVS, we would not expect it to require removal or prevent a mortgage from being issued given the publication of the inspection protocol that surveyors can use to make a judgement.
