Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, on what date his Department will announce plans for the deployment of new nuclear generation projects at (a) Wylfa and (b) Oldbury.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
Great British Energy – Nuclear purchased the sites at Wylfa and Oldbury in 2024. As sites which have previously hosted a nuclear power station, both have positive attributes for new nuclear. No decisions have yet been taken on any projects to be deployed at either site. Our plans will be set out in due course

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, with reference to the National Audit Office Report entitled Energy efficiency installations under the Energy Company Obligation, published on 14 October 2025, what the cost to the public purse is of remediating defective retrofit work carried out under the Energy Company Obligation scheme in Wales.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The remediation costs sit with the original installer and we have been clear that no household should be asked to pay any money to put things right. We expect most remediation for solid wall insulation installed under ECO4 or GBIS to cost between £250 and £6,000 for IWI and £5,000 and £18,000 for EWI. This should be covered by the guarantee should the installer no longer be trading.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, with reference to the National Audit Office Report entitled Energy efficiency installations under the Energy Company Obligation, published on 14 October 2025, how many homes in Wales have had defective retrofit work carried out on them under the Energy Company Obligation scheme.
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. Two random samples of audits of external (EWI) and internal wall installations (IWI), across the household populations of both schemes were commissioned to understand non‑compliance rates. 98% of EWI audits need to be remediated. For IWI, that number is 29%.
The samples are not large enough to reliably perform any regional analysis. As we continue with further audits, we will seek to begin to collect this data.
