Guidance: Cavity wall insulation (CWI): consumer guide to issues arising from installations

Cavity wall insulation (CWI) is one of the most cost-effective means of improving energy efficiency in people’s homes. It is installed in suitable homes and supported by appropriate installation standards and guarantees.

In a small number of instances however, genuine issues have arisen in the home as a result of a CWI installation. This guidance outlines the routes to redress under these circumstances.

In addition claims management companies (CMC) or solicitor’s firms have contacted householders, offering to represent them in return for compensation for damage caused to their homes by the insulation.

The guidance provides:

  • advice on how to avoid becoming victims of fraudulent CWI claims
  • signposts to organisations that can offer support if problems arise
