Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what provisions his Department has put in place to help ensure the professional competency of firms that install insulation with support from the Great British Insulation Scheme.

We recognise the importance of facilitating a competent and robust supply chain. All installations under government energy efficiency schemes, including the Great British Insulation Scheme, must be carried out by a TrustMark registered business. This includes a requirement to meet independent industry standards and to provide a warranty to the householder, in case something goes wrong.

The government recognises the need to reform a fragmented system and will introduce plans to drive-up quality and protect consumers through the Warm Homes Plan.
