Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what regulatory mechanisms exist to require installers to carry out corrective works where insulation products installed under publicly funded energy efficiency schemes are found to be (a) defective and (b) improperly installed.

Insulation installations under energy efficiency schemes must be carried out by TrustMark registered and PAS 2030 certified businesses, in accordance with PAS 2035. A guarantee must be purchased for each installation. Solid wall insulation installations attract a 25 year guarantee up to a value of £20k.

In the event that installers do not remediate work, TrustMark and PAS 2030 certification bodies have the ability to suspend a business until works are rectified. TrustMark’s complaint handling process offers access to a Dispute Resolution Ombudsman which offers registered businesses and customers an impartial and flexible way of reaching a resolution. Where an installer business ceases to trade, a claim can be made on the guarantee.
