Question to the Department for Energy Security & Net Zero:
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 - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential merits of conducting a government inquiry into the installation of air source heatpumps and solar panels within the ECO4 scheme.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
ECO4 has played a part in delivering clean heat technologies; however, issues identified by the NAO and PAC support a shift to a more direct, publicly-funded approach focused on technologies that cut bills and accelerate the transition to clean heat such as heat pumps, solar PV and batteries. The government is providing an additional £1.5 billion—taking planned capital investment to almost £15 billion—to upgrade low‑income homes and scale clean home‑energy technologies. Deployment will be further supported through wider policies and details of this will be set out soon in the Warm Homes Plan.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what safeguards are being established to protect people who are waiting for rectification of work carried out under the ECO 4 Scheme by Consumer Energy Solutions following the company entering administration.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
All completed installations under ECO4 and GBIS are covered by a guarantee. Consumers should approach their guarantee provider for support within the bounds of their policy. We are actively and urgently working with Trustmark, MCS and scheme providers to consider how best to support recipients of CES’ work. We will provide further advice as soon as possible. No household should be asked to pay to rectify non-compliant works.
