PARLIAMENTARY WRITTEN QUESTION
(10 March 2026)

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to help support households affected by defective (a) retrofit and (b) insulation works carried out under Government schemes.

Asked by:
Sarah Hall (Labour)

Installers under Government schemes must be TrustMark registered and/or Microgeneration Certification Scheme (MCS) certified. TrustMark and MCS offer dispute resolution processes to consumers. Consumers must also be provided with a suitable guarantee.

The Department is delivering a nationwide find‑and‑fix programme so all households affected by non-compliant external wall insulation installed under ECO4/GBIS receive a free audit, with installers required to put right any issues at no cost to consumers.

We are committed to reforming the consumer protection system, as set out in the Warm Homes Plan. We will consult this year on options for increasing Government oversight of schemes.
