Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, 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 Obligation.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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 possible, to seek support through available redress routes, including guarantee providers where applicable.
The Government recognises that aspects of the current system have not consistently delivered strong outcomes for all consumers. To simplify the system for consumers and installers, we will consult this year on options for bringing the oversight of home upgrades supported by government schemes under closer government control.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, 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.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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 installers, certification bodies and guarantee providers within the consumer protection arrangements at time of installation.
The Government recognises that aspects of the current system have not consistently delivered strong outcomes for all consumers. To simplify the system for consumers and installers, we will consult this year on options for bringing the oversight of energy efficiency and microgeneration installations for government schemes under closer government control.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, whether the Warm Homes Plan will include the use of clerks of works or equivalent independent site‑inspection roles.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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 within PAS 2035 has that role of project manager, taking overall responsibility for overseeing from inception to completion.
Government is consulting on reforms to the consumer protection system and seek views on proposals for government to have stronger central oversight of the system for government funded home upgrade schemes. This will include how government can set clear expectations, monitor performance and ensure accountability across schemes to drive higher quality installations, which are carried out right first time.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to help ensure that home gas suppliers charge reasonable renewal prices.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, whether a fraud risk assessment was carried out during the design of the Warm Homes Plan.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
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.

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 Policy Paper published on 11 February 2026 entitled Local Power Plan, when the route to market for unlocking SLES will be operational.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
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.
