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, what estimate his Department has made of the number of households not on the national grid for (a) gas and (b) electricity in each constituency in Scotland.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The department publishes estimates of the number of domestic properties not connected to the gas network in Great Britain by country, English regions, local authority and constituency.
For Northern Ireland, data on the total number of gas connections is available via the Annual Retail Energy Market Monitoring Report.
Equivalent figures for the electricity network are not published.

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 adequacy of regulatory frameworks in ensuring that rural communities have access to electricity grid connections.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Government works with Ofgem to ensure grid investment supports all communities, including remote rural areas. Ofgem has allocated £22 billion for network upgrades under the current electricity distribution price control (2023–2028). The next price control (2028–2033) will require distribution network operators to produce long-term regional network plans.
Ofgem is also conducting an ‘end-to-end' review of connection obligations and incentives to improve customer service and network operator accountability, with proposals to be published later this year.
These measures enable timely upgrades and connections for rural communities, supporting low-carbon technologies while maintaining affordability for consumers.

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.

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 implications for his policies of trends in the level of public confidence in Government-backed net zero projects.
Answered by Katie White - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
79% of the UK public are concerned about climate change [1], and are aware of and support the government’s net zero target [2]. We have a credible plan for delivering net zero. The Carbon Budget and Growth Delivery Plan sets out how the UK will continue to reduce emissions in a way that lowers bills and secures good jobs, as well as bringing warmer homes, cleaner air and increased access to nature – delivering tangible improvements to the everyday lives of people now and for generations to come.
