Energy Company Obligation: Fraud

Asked by Liz Saville RobertsPlaid CymruDepartment for Energy Security and Net ZeroTabled Answered 15 January 2026UIN 104826

The question

To ask the Secretary of State for Energy Security and Net Zero, what steps he has taken to address fraud by companies in the ECO4 scheme since the publication of the National Audit Office investigation into the performance of ECO in October 2025.

Answered by Martin McCluskey

For existing schemes, we work with Ofgem, TrustMark and energy suppliers to detect, prevent and deter fraud. When Ofgem is notified of suspected fraud, they engage with suppliers, Action Fraud and the Serious Fraud Office to ensure robust investigation.

We are taking on board the lessons identified by the NAO, embedding these into our future consumer protection systems, and applying relevant lessons from grant-funded programmes as part of our revised approach to assurance in all retrofit schemes. We have increased departmental oversight of consumer levy funded schemes and will publish an updated Accounting Officer statement with our 2025-26 annual report.
