Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what mechanisms are in place to hold contractors and installers accountable for poor workmanship on government-backed insulation schemes in cases where the original firms have since ceased trading.

We have been clear that the original installer is responsible for remediating issues with their work and for the costs of doing so. Where an installer ceases to trade or in some cases fails to rectify an issue, TrustMark require a guarantee to have been issued which for SWI will cover up to £20k.

We are working with Ofgem, TrustMark, certification bodies, energy suppliers and guarantee providers to encourage businesses to fulfil their responsibilities.

Where installers refuse to engage with remediation requests, TrustMark and certification bodies can suspend or remove their certifications. This prevents them being awarded any new work.
