What his Department's plans are for the future of the Boiler Upgrade Scheme.

The Government is working on a comprehensive Warm Homes Plan for households to cut energy bills for good and will publish more details soon.On 18 November, the Government published the response to the recent consultation, which closed on 11 June. This provides detail on amendments to the Boiler Upgrade Scheme which will be implemented from next year. These changes are designed to increase access, stimulate further demand, and enhance existing consumer protections, making low carbon heating technologies more accessible to a wider range of property owners and small businesses.

Pursuant to the Answer to Question 88051 answered on 17th November 2025, if he will consider publishing interim data on this topic.

Fuel poverty statistics are based on the English Housing Survey which is collected annually. The department does not hold interim statistics or data on fuel poverty collected between English Housing Survey samples. The date for the next publication in 2026 will be pre-announced in line with the standards for official statistics.

Pursuant to the Answer to Question 88054 answered on 17th November 2025, how involve is defined with regard to consulting Fire and Rescue Services during public consultation.

The relevant part of the Planning Practice Guidance on expected interactions between local planning authorities and local fire and rescue services with respect to grid-scale batteries is at paragraph 35.

What steps he plans to take to ensure local communities are consulted on the safety of proposed battery storage sites.

Developers of standalone grid-scale batteries must seek planning approval as outlined in the Town and Country Planning Act 1990. This requires local planning authorities to undertake a formal period of public consultation for at least 21 days. Those living near to the proposed site may offer views or detailed information relevant to the application, including on safety measures. Planning Practice Guidance recommends that developers should also engage with local fire services ahead of submitting their planning application.

Pursuant to the Answer of 31 October 2025 to Question 84891 on Fuel Poverty: Ely and East Cambridgeshire, when he plans to publish regional fuel poverty figures for Ely and East Cambridgeshire constituency for 2024.

Subregional fuel poverty statistics are normally published annually in April. The date for the next publication in 2026 will be pre-announced in line with the standards for official statistics. These statistics will provide data for 2024 for regions, local authorities, parliamentary constituencies, and Lower Super Output Areas.

When his Department last made an assessment of the effectiveness of the (a) planning practice guidance and (b) other aspects of the safety framework for grid-scale batteries.

In August 2023, the government updated its Planning Practice Guidance to encourage battery storage developers to consult Local Fire and Rescue Services (FRSs) before submitting applications and for planning authorities to involve FRSs during public consultation. The guidance also advises authorities to refer to National Fire Chiefs Council recommendations. The government has committed to updating planning practice guidance on renewable and low carbon energy development. The government monitors the safety framework for grid-scale batteries closely. In October, I hosted a roundtable discussion with regulators including the Health and Safety Executive and Environment Agency on the safety framework. My department works closely with regulators through the industry-led Health and Safety Governance Group to ensure that the framework remains robust and future proofed.

Pursuant to the Answer of 27 October 2025 to Question 83177 on Batteries: Storage, if he will make an assessment of the effectiveness of the Planning Practice Guidance in ensuring that battery developers consult fire services.

The Government engages regularly with the National Fire Chiefs Council, representatives of local authorities and other key stakeholders to gather feedback on the effectiveness of the safety framework for grid-scale batteries, including the Planning Practice Guidance (PPG). The PPG sets a clear expectation that developers engage with fire and rescue services before they submit a planning application for a grid-scale battery site. It also encourages local planning authorities to engage with fire services as part of the formal period of public consultation and before reaching a planning determination. As such, government considers the PPG to be effective in setting out clear expectations for developers and decision-makers on grid-scale planning applications.

Pursuant to the Answer of 20 October 2025 to Question 80134 on Fuel Poverty: Ely and East Cambridgeshire, if he will make an assessment of trends in the level of fuel poverty in Ely and East Cambridgeshire constituency in 2024.

Fuel poverty estimates at sub-regional level are official statistics in development. Since they are modelled estimates, they should not be used to identify detailed trends over time. However, regional fuel poverty figures calculated from the English Housing Survey are comparable over time. The latest statistics (Trends table 4) show that the proportion of households in fuel poverty in the wider region East of England, containing Ely and East Cambridgeshire, has decreased from 18.8% in 2010 to 9.0% in 2024. This is measured using the Low Income Low Energy Efficiency metric.

Pursuant to the Answer of 17 October 2025 to Question 77318 on Batteries: Storage, for what reason he does not plan to make fire services statutory consultees on planning applications involving battery energy storage sites.

Planning Practice Guidance strongly recommends that battery developers engage with fire services ahead of the submission of their planning application. However, further to dialogue with the National Fire Chiefs Council, government is of the view that making fire services statutory consultees would risk creating disproportionate administrative burdens for the fire services.

What economic analysis his Department has conducted on the potential impact of non-price factors in decisions on whether sub-100MW bioenergy power stations currently supported by Renewable Obligation Certificates will receive transitional support from 2027.

Small scale biomass generators have received many years of subsidy support under the Renewables Obligation scheme. These assets begin to roll off the scheme from 2027. Any assessment of further support must fully take into account value for money (including consumer bill impacts), electricity system and broader considerations – such as environmental impacts, which are a matter for Defra. Biomass electricity generation is often more expensive than alternatives and reducing energy bills is a priority for this Government.

What assessment he has made of trends in the level of fuel poverty in Ely and East Cambridgeshire constituency.

The latest sub-regional fuel poverty statistics, published in April 2025, provide data for 2023. In the Ely and East Cambridge constituency, it is estimated that 4,487 households were in fuel poverty in 2023, equating to 9.6% of all households in the area. As these sub-regional fuel poverty statistics are modelled estimates, we advise against making comparisons over time.

What steps he is taking to tackle fuel poverty in rural areas.

Tackling fuel poverty is a priority for this Government. We are committed to publishing a new Fuel Poverty strategy for England, which will ensure that many more fuel poor households achieve affordable warmth by 2030, alongside the Warm Homes Plan. We are currently supporting rural and off gas grid homes through schemes including the Homes: Local Grant, which is aimed at low income and vulnerable consumers. Support is also available through the Warm Home Discount which has been expanded for this winter, – increasing the total number of households that will receive the discount from 3.2 million to around 6 million.

What assessment he has made of the potential impact of decoupling electricity prices from wholesale gas prices on household energy bills.

As unabated gas generation is displaced and transitions to a reserve role, wholesale electricity prices will increasingly decouple from the price of gas. Accelerating the deployment of renewable generation, as we are through our Clean Power 2030 Mission, will reduce the frequency with which gas sets the marginal price, helping to rapidly decouple electricity from gas prices without the need for more complex arrangements. This will in turn reduce consumer exposure to volatile international gas prices.

Whether he plans to introduce a social tariff for energy.

I know that more needs to be done to support vulnerable households that are struggling with bills whilst we transition to clean power. The Warm Home Discount provides a £150 rebate off winter energy bills for eligible low-income households. On 19 June we announced that we are expanding the Warm Home Discount to around an additional 2.7 million households. This means that from next winter, around 6 million low-income households will receive the £150 support to help with their energy bill costs. On 25 September we published a consultation setting out our intention to continue support for those 6 million households. The consultation sets out proposals for the next scheme period (up to winter 2030/31), after current regulations expire on 31 March 2026. Government is gathering feedback from stakeholders on the design of the core elements of the scheme, options for delivery of the scheme in Scotland, proposals to change some elements of the scheme for suppliers, a call for evidence on Industry Initiatives, and a call for suggestions for future improvements during the next scheme period. The consultation closes on Thursday 20 November.In the interim, I appreciate that one of the biggest practical barriers to providing help to households that need it, is the availability of the right data to target financial support and advice. The Department for Net Zero and Energy Security is working closely with other Government Departments to unlock the data that will enable us to target support more effectively to those who need help with their energy bills.

What support he plans to provide to households in Ely and East Cambridgeshire constituency with energy bills in winter 2025-26.

The Government believes that our mission to deliver clean power by 2030 is the best way to break our dependence on global fossil fuel markets and protect billpayers permanently. We recognise that we need to support households struggling with bills whilst we transition to clean power by 2030. This is why we delivered the Warm Home Discount to around 3 million eligible low-income households last winter. On 19 June we announced that we are expanding the Warm Home Discount to around an additional 2.7 million households. This means that from this winter, around 6 million low-income households will receive the £150 support to help with their energy bills.

What steps he is taking to help reduce regional inequalities in energy bills.

Energy prices vary regionally due to differences in the costs of local electricity and gas distribution networks, which are influenced by factors like population density and infrastructure maintenance. The energy price cap accounts for these differences in regional network costs by adjusting unit rates and standing charges. The Government knows that, for many consumers, too much of the burden of the bill is placed on standing charges. The Government is committed to reducing consumer bills and bearing down on the standing charges and have worked constructively with the regulator, Ofgem, on this issue.

Whether he plans to provide information to communities affected by battery energy storage sites on the safety of those sites.

Communities near potential grid-scale battery sites should be informed about them via planning law, which requires local planning authorities to notify neighbours regarding planning applications either by site notice or letter, and to publish information about the application on a website. This provides the local community the opportunity to make representations about the applicationThe government has published guidance on existing battery safety standards.[1] Separately, the Health and Safety Executive has published guidance[2] for battery duty-holders under health and safety law. While intended for developers, communities may find this information helpful in gaining assurance that appropriate standards are in place for batteries. In GB, fires at battery sites are rare and are mitigated by a regulatory framework overseen by the Health and Safety Executive. The latest available 5-year annual average fire incidence rate for GB batteries is 0.7% (2020/21 to 2024 to 2025)[1], lower than for wider non-domestic building fires in England at 0.8% (2019/20 to 2023/24)[2].

What assessment he has made of the adequacy of safety regulations for battery energy storage sites.

In GB, battery fires are rare and are mitigated by a robust framework overseen by the Health and Safety Executive, requiring responsible parties to ensure safety throughout a battery’s deployment. The latest available 5-year annual average fire incidence rate for GB batteries is 0.7% (2020/21 to 2024 to 2025)1, lower than for wider non-domestic building fires in England at 0.8% (2019/20 to 2023/24).2 To complement this regulation, DEFRA is consulting on including batteries within the Environmental Permitting Regulations (EPR). EPR requires sites to demonstrate to the Environment Agency that harms are avoided or controlled and provides for ongoing regulatory inspections.

Whether his Department plans to make (a) local fire services and (b) the Environment Agency statutory consultees for battery energy storage sites.

This government takes fire safety extremely seriously. In GB, fires at battery sites are rare and are mitigated by a regulatory framework overseen by the Health and Safety Executive. The latest available 5-year annual average fire incidence rate for GB batteries is 0.7% (2020/21 to 2024 to 2025), lower than for wider non-domestic building fires in England at 0.8% (2019/20 to 2023/24). We do not intend to make fire authorities or the Environment Agency statutory consultees on planning applications involving Battery Energy Storage Solutions (BESS). However, DEFRA is currently consulting on the principle of including batteries under the scope of the Environmental Permitting Regulations (EPR). EPR requires sites to demonstrate to the Environment Agency that harms are avoided or controlled and would provide for ongoing regulatory inspections.

What steps he is taking to safeguard critical energy infrastructure against the extreme summer temperatures.

Great Britain’s electricity infrastructure is highly resilient and designed to operate in a wide range of conditions. The risks to GB's electricity system from extreme heat are low, but in the unlikely event of any impacts, the energy sector has long-standing plans and procedures to minimise disruption to customers, as set out in the National Emergency Plan for Downstream Gas and Electricity. Government works closely with industry to minimise the risk of unplanned outages and in line with licence conditions, the National Energy System Operator is required to assess network operators’ resilience to a range of weather events, including extreme temperatures.
