Faulty energy installations – Public Accounts Committee

In this session, MPs will explore why there were such high levels of poor quality and faulty installations of insulation under the government’s Energy Company Obligation (ECO) scheme, which was meant to tackle fuel poverty and reduce emissions through home retrofits. Tens of thousands of these homes now need repairs to tackle health and safety and damp and mould risks. Almost all (98%, up to 23k) of homes with external insulation, and a little under a third (29%, up to 13k) of homes with internal insulation installed under the ECO are now estimated to need fixing. At September 2025, less than 10% of the homes estimated to be affected had been fully remediated. The Committee will first hear from Simon Ayers MBE (Chief Executive Officer of TrustMark) and Matt Gantley (Chief Executive of UKAS). The second panel will consist of Jeremy Pocklington CB (DESNZ Permanent Secretary), Clive Maxwell CB CBE (DESNZ Second Permanent Secretary) Deborah Chittenden (Director – Net Zero Buildings: Transformation at DESNZ), and Jonathan Brearley (Chief Executive Officer of Ofgem), and Kiera Schoenemann (Director of Audit and Compliance, Delivery and Schemes at Ofgem).
