Insulation: Housing
The question
To ask the Secretary of State for Energy Security and Net Zero, whether his Department is taking steps to investigate incidents of incorrectly installed cavity wall insulation that was installed before 2021.
Answered by Martin McCluskey
Cavity wall insulation (CWI) is one of the most cost-effective means of improving energy efficiency in people’s homes when installed in suitable homes and supported by appropriate installation standards and guarantees. However, the Government is aware that there are instances where issues have arisen in some homes which may be attributed to a CWI installation.
For installations under previous government schemes, guidance is available on the Government’s website for consumers who suspect they may have faulty CWI installed in their home, outlining routes to redress under these circumstances at https://www.gov.uk/government/publications/cavity-wall-insulation-cwi-consumer-guide-to-issues-arising-from-installations.
