To ask the Scottish Government, regarding the ECO4 scheme for energy-efficiency upgrades, what advice it provides to homeowners seeking compensation where installers or scheme providers are no longer trading.
The Scottish Government funds both the Home Energy Scotland and Advice Direct Scotland service to provide free and impartial advice. Property owners who may be affected by the failure of this UK Government scheme can contact these services for advice.
The Energy Company Obligation (ECO4) scheme requires installers to reduce energy bills by installing energy efficiency improvements such as insulation. The UK Government are responsible for the design and regulation of the ECO4 scheme, this is administered by Ofgem on their behalf.
Installers delivering improvements as part of the ECO4 scheme were required to be registered with TrustMark, the UK Government’s trusted trader scheme. They were also required to be certified installers with a relevant industry body and ECO4 installations had to be covered by a guarantee. Where an installer has ceased trading, the UK Government advises property owners to contact the guarantee provider to arrange for remediation of any outstanding defects or damage.
Consumer protection, product and business regulation are reserved matters. The UK Government has published advice for property owners about their key rights and protections under consumer law. Buying green heating and insulation products: consumer guide - GOV.UK
