Whether the Warm Homes Plan will include the use of clerks of works or equivalent independent site-inspection roles.
Energy efficiency measures installed under current Government energy efficiency schemes must be compliant with PAS 2035/2030 to ensure installations are done to the highest quality and the risk of unintended consequences. The Retrofit Coordinator role wit...
Whether his Department plans to provide remedial funding to address defects arising from government-backed home energy efficiency schemes that pre-date the Energy Company Obligation.
The Department does not currently have plans to provide general remedial funding for defects arising from legacy home energy efficiency schemes that predate the Energy Company Obligation. Responsibility for addressing defects sits primarily with installer...
What plans his Department have to provide support to households continuing to be affected by defects to their homes arising from energy efficiency schemes that pre-date the Energy Company Obl
The Government recognises that some households remain affected by defects arising from historical energy efficiency schemes, including those that predate the Energy Company Obligation. Households should first contact their installer, and where this is not...
Whether a fraud risk assessment was carried out during the design of the Warm Homes Plan.
The Government has a zero-tolerance approach to fraud. The Government requires robust counter‑fraud controls to be built into the design and delivery of all energy efficiency and clean heat schemes, in line with cross‑government standards and Public Sector Fraud Authority guidance. Future scheme design and delivery will take into account lessons learned from previous iterations of HMG schemes.
With reference to the Policy Paper published on 11 February 2026 entitled Local Power Plan, when the route to market for unlocking SLES will be operational.
The Department recognises requests to take steps to better enable local energy markets and trading to lower bills and increase the resilience of the electricity networks. The Department is investigating barriers to local supply and is working with Ofgem, Great British Energy and relevant stakeholders to find solutions that work in the best interests of local generators and consumers. The Department is also actively exploring policy options that will unlock Smart Local Energy Systems, including working with Innovate UK, local government and communities to develop opportunities for place‑based approaches. Ofgem and Elexon’s work on code modifications, like P441, will help more community energy groups identify and understand the different routes to market in order to sell their energy. Industry feedback informed the Draft Modification Report considered by the Panel on the 12 March leading to the Final Modification Report submitted to Ofgem on the 17 March.
What steps his Department is taking to help ensure that home gas suppliers charge reasonable renewal prices.
Domestic energy consumers are protected by the energy price cap set by Ofgem, which limits the unit rates and standing charges that can be charged by energy suppliers, including limits on the profit that energy suppliers can make from default tariffs. From 1 April until the end of June, the price cap has fallen by 7% or £117 to £1,641 per year for an average dual fuel customer paying by Direct Debit. The price cap for that period is fixed and will not change. You can find more information on the impact of Government action here:Your energy bill from April: what’s changing - GOV.UK.
When his Department plans to respond in full to the Public Account Committee report on Faulty Energy Efficiency Installations, published on 23 January 2026.
The Department will be responding to the Public Accounts Committee via Treasury Minute as is the standard process.
If he refer the issue of fraud within ECO4 and Great British Insulation Scheme to the Serious Fraud Office as recommended by the Public Account Committee report on Faulty Energy Efficiency Installations, published on 23 January 2026.
The Department will be responding to the Public Accounts Committee via Treasury Minute as is the standard process.
If his Department will publish an annual report on (a) its retrofit schemes, (b) their level of compliance, (c) estimated fraud and (d) their effectiveness.
The Department will publish monitoring statistics and evaluation of policies announced in the Warm Homes Plan. DESNZ currently publishes statistics covering the uptake and impacts of energy efficiency measures on GOV.UK.
With reference to page 88 of the Department's policy paper entitled Warm Homes Plan, published on 21 January 2026, when he plans to publish the consultation on (a) options for bringing the oversight of energy efficiency and microgeneration installations for government schemes under closer control and (b) the role of the Warm Homes Agency.
As set out in the Warm Homes Plan, we will consult this year on options for bringing the oversight of energy efficiency and microgeneration installations for government schemes under closer government control and the role of the Warm Homes Agency.
If he will release annual reports estimating the level of fraud and non‑compliance in retrofit schemes.
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.
What recent assessment he has made of the adequacy of the availability of energy support for (a) ill and (b) other vulnerable people.
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.
If he will make an assessment of the potential merits of introducing a social energy tariff.

What support is available to households that have paid to rectify non-compliant works under the ECO4 scheme.
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.
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.
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.
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.
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.
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.
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.
How many homes in Wales are waiting for rectification of work carried out under the ECO4 Scheme by Consumer Energy Solutions.
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.
What steps his Department is taking to help protect jobs and retain skills across Wales, in the context of the time taken to announce the Warm Homes Plan.
Government is committed to supporting businesses to transition to new opportunities in the sector, including exploring options to support the supply chain to transition from ECO and GBIS to capital scheme delivery.The Warm Homes Plan, due to be published soon, will set out government’s plans to invest nearly £15 billion to upgrade low‑income homes and scale clean home‑energy technologies. The number of UK jobs supported in clean energy industries and their supply chains is estimated to increase from around 440,000 today to around 860,000 by 2030 and we are working closely with the sector to support its growth.
What proportion of the funding allocated to the Warm Homes Plan in the (a) Spending Review and (b) 2025 Autumn Budget has been assigned to Wales.
To ensure the bill savings from the transition to clean energy technologies are felt in all parts of the country, the different needs and approaches of the Devolved Governments will need to be recognised. The UK Government will continue to work closely with the Welsh Government and will publish the Warm Homes Plan soon.
