Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if she will take steps to introduce post-installation inspections for ECO4-funded works to ensure that those works are carried out to a high standard.

Under ECO4 installations of all energy efficiency measures, excluding district heating system connections, need to be carried out by TrustMark registered businesses, which are required to adhere to the independent Publicly Available Specification standards.

TrustMark carries out post-installation inspections on up to 10% of all projects, taking a risk-based approach.
