The remediation costs sit with the original installer. We expect remediation for solid wall insulation installed under ECO4 or GBIS to cost between £250 and £6,000 for IWI and £5,000 and £18,000 for EWI. This should be covered by the guarantee should the installer no longer be trading.

There have been some instances where costs are greater than £20,000 (complex cases), we are working with the sector to find solutions and for these faulty installations to be fixed.

Wider consumer protection reform will ensure that financial protections are clearly accessible and fully protect the consumer.
