Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, if he will release annual reports estimating the level of fraud and non‑compliance in retrofit schemes.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
We have received similar recommendations from both the NAO and the PAC. We are considering these reports and the recommendations and will be responding to these in full in due course.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, if he will make an assessment of the potential merits of introducing a social energy tariff.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government understands the need to target support to those who need it most. That is why on 30 January, we announced the continuation of the Warm Home Discount scheme, providing around 6 million eligible households with the £150 rebate on their energy bills every winter until 2030/31. This means that millions of households every year who need support with their energy bills will receive the Warm Home Discount for the rest of the decade.
We also committed to exploring additional improvements to the scheme. While we consider options for future bill support, we are working across Government to improve access to and sharing of data to target support more effectively in the future. Specifically, the ‘Kickstarter’ programme under the National Data Library will test how public sector data can be better joined up to improve access to government programmes.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what support is available to households that have paid to rectify non-compliant works under the ECO4 scheme.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
We have been clear that the original installer is responsible for remediating issues with their work and for the costs of doing so. Where an installer ceases to trade or in some cases fails to rectify an issue, protections under the guarantee should be invoked. TrustMark require a guarantee to have been issued, which for Solid Wall Insulation will cover up to £20k.
If consumers have a separate complaint about their installation, they can follow the steps set out in the TrustMark complaints process here. This includes the Dispute Resolution Ombudsman if the consumer wishes to progress with legal actions.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what discussions his Department has had with the Welsh Government on the the Warm Homes Agency; and if he will set out how the Agency will operate in Wales.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government has been actively engaging with the Welsh Government on the Warm Homes Agency since Spring 2025, including discussions on how future arrangements of the Agency would work with Devolved Governments. The Agency will only operate in Wales with agreement from the Welsh Government, and discussions to secure this agreement are ongoing.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, how many homes in Wales are awaiting rectification of work carried out under the ECO4 scheme; and what is the constituency‑level breakdown of those cases.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government commissioned an independent statistical audit in April 2025. Unfortunately, the samples are not substantial enough to reliably perform regional analysis.
Due to the level of non-compliance found for EWI measures, the Government is offering a comprehensive on-site audit to all households where external wall insulation (EWI) was installed under ECO4 or GBIS. This check will be provided at no cost to the consumer.
Should any issues requiring action be found, these should be remediated by the original installer. Where the installer has ceased trading, protections under the installation guarantee policy should be invoked.
Checks across all measures under ECO4 and GBIS, will continue to be carried out by TrustMark and certification bodies as part of routine surveillance.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, with reference to page 48 of the Department's policy paper entitled Warm Homes Plan, published on 21 January 2026, what proportion of the total funding provided for the Barnett consequentials will be received by (a) Wales, (b) Scotland and (c) Northern Ireland.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Treasury has not yet confirmed the specific Barnett consequential appointments of the Government’s spending commitment for the Warm Homes Plan.
Scotland, Wales and Northern Ireland each have unique devolution settlements. The age, tenure, type and size of building stock varies across different parts of the UK. Therefore, some aspects of the Warm Homes Plan will apply equally in England, Scotland, Wales and Northern Ireland while other parts will not be relevant in all nations of the UK.
The UK Government will continue to work closely with the Devolved Governments in delivering 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, how many homes in Wales are waiting for rectification of work carried out under the ECO4 Scheme by Consumer Energy Solutions.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
We are working with MCS and certification bodies to determine the number of homes in Wales awaiting remediation of work carried out by Consumer Energy Solutions under ECO4.
Ministers have been clear that no household should be asked to pay to fix work that is non‑compliant through no fault of their own. Where issues are identified, the installer responsible is expected to put them right. Where an installer has ceased trading or fails to remediate, households should contact their relevant guarantee provider to access the protections of their guarantee. Further advice will be provided to affected households shortly.
