Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, whether he plans to take steps to enable cavity wall insulation suppliers to award compensation to relevant households under the Government's cavity wall insulation scheme.

The Government recognises that there have been cases of cavity wall insulation being installed in unsuitable homes or being installed poorly.

All CWI installed under current government schemes must be completed by TrustMark registered businesses, adhering to the latest PAS 2030/2035 standards. TrustMark offers a step-by-step process in case of issues, including escalation to Alternative Dispute Resolution and the Dispute Resolution Ombudsman. If the installer is no longer in business the guarantee provider must step in.

Where an installer is not TrustMark registered, the Government has published guidance setting out steps for consumers who suspect they have faulty CWI installed.
