Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to ensure that (a) internal and (b) external insulation installed under Government energy efficiency schemes are fitted to a high standard in Surrey Heath constituency.

Companies installing insulation under the Government’s energy efficiency schemes must be registered with Trustmark and carry out work to the PAS2035 standard.

We have improved the quality assurance and consumer protection systems since identifying the issues with solid wall insulation under ECO4 and GBIS.

We will be offering a comprehensive on-site audit to all households that received external wall insulation under ECO4 and GBIS and any issues will be fixed at no cost to the householder.

TrustMark and certification bodies can suspend companies who do not meet the expected standards, and will continue to enforce the robust, published reinstatement policy.
