Insulation: Housing

Asked by Imran HussainLabourDepartment for Energy Security and Net ZeroTabled Answered 7 November 2025UIN 86678

The question

To ask the Secretary of State for Energy Security and Net Zero, what financial or practical support is available to homeowners whose properties have been damaged by poorly installed insulation under government schemes; and whether he plans to establish a dedicated compensation or remediation fund for such properties.

Answered by Martin McCluskey

The cost of remediation sits with the original installer. For every measure installed under TrustMark schemes, a guarantee is required to be in place. If the installer is no longer trading, then the guarantee policy will kick in up to the cap for that policy. For SWI the cap is £20k.

In rare cases where the costs exceed the cap, the Department will continue to facilitate solutions with organisations across the sector.

As part of our reforms, we will be improving protections for consumers, ensuring, in the rare cases they are needed, financial protection products fully protect consumers and it’s clear how consumers get the help they need.
