Insulation: Housing
- Question
-
To ask His Majesty's Government what action they will take to ensure that all properties affected by defects under the Great British Insulation Scheme and the Energy Company Obligation scheme are remediated promptly and safely.
- Answer
-
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.
