Due to the level of non-compliance in EWI, the Government is offering audits to all households where External Wall Insulation (EWI) was installed under ECO4 or GBIS.

If non-compliance is found, the original installer is responsible for the cost of putting the work right. Should the installer have ceased to trade, the protections under the 25-year guarantee can be invoked.

Checks across all measures under ECO4 and GBIS, will continue to be carried out by TrustMark and certification bodies as part of routine surveillance.
