Written questions by Dillon.

What assessment his Department has made of the potential merits of hydrotreated vegetable oil as a transitional heating solution for rural homes using oil heating.

The Government launched a consultation on 18 November to explore alternative clean heating solutions that may play a role in some homes, including renewable liquid fuels (RLFs) such as hydrotreated vegetable oil. The consultation will run for 12 weeks. The Government will review evidence from this consultation to help inform any future decision on whether or not to support the use of RLFs in heating.

What funding is available to support community energy projects in Newbury constituency.

Great British Energy (GBE) and the UK government will turbocharge support for local and community energy projects across the UK. In 2025/26, Great British Energy have allocated £5 million to the Great British Energy Community Fund (GBECF), a grant scheme designed to help community groups develop local clean power projects. £6.8 million has been allocated to maintain Local Net Zero Hubs located across England, which provide free expertise and resources to help local authorities deliver clear energy projects. GBE is in the process of developing its longer-term funding offer and strategic support for working with Local Government and Community Energy Groups, as well as working with devolved governments. This includes commercial, technical and project planning assistance to increase capability and capacity to build a pipeline of successful projects in local areas. As set out in their Strategic Plan, published on 4 December 2025, GBE aims to support over 1,000 local and community projects by 2030.

What assessment his Department has made of the adequacy of the affordability of heat pump installation for households using oil heating in rural areas.

Government expects the transition to clean heat will involve installing a heat pump for most oil-heated homes as they are cost-effective, proven technologies and several government schemes support their installation. We will share more details in the Warm Homes Plan soon. The Boiler Upgrade Scheme has grants available for air source and ground source heat pumps of £7,500. There is also a 0% rate of VAT on heat pump installations until March 2027. Low income and fuel poor homes may be able to access support through the Warm Homes: Local Grant. We are undertaking research on the costs of different approaches to decarbonising the most complex housing archetypes and expect to receive results early next year.

What steps he is taking to lower energy prices for people in Newbury constituency.

Thanks to decisions in Government's Autumn Budget, the Department for Energy Security and Net Zero (DESNZ) will deliver an average £150 of costs off household energy bills from April 2026. As a result of this action, people in Newbury can expect to make a significant saving on their bills. In addition, in 2024-2025, 2,854 households (6.5%) in Newbury benefited from the Warm Home Discount - a £150 discount on their energy bill. This winter, we are expanding this discount so that around 6 million low-income households will receive this support, including an approximate additional 350,000 households in the South East region. Beyond these measures, this Government is taking back control of our energy to prevent the British people from being left exposed to price shocks caused by our dependence on fossil fuel markets. We are delivering the biggest investment in clean, low-cost energy in British history, so we can build a system that protects billpayers permanently.

What assessment he has made of the potential merits of removing all social and environmental levies from electricity bills.

The reductions in electricity prices announced at the Budget, particularly the reduction in the Renewables Obligation, are a significant step forward in our ambition to reduce electricity bills. As stated, we intend to set out more detail in our Warm Homes Plan as to how we can further target the savings announced in this Budget at electricity bills, including those from ending the ECO scheme. The Budget also delivers on the major principle that we should fund more of the investment we need in our energy system through public expenditure rather than levies, moving £7bn into public expenditure. We are delivering the biggest public investment in home energy efficiency ever, increasing the settlement we received at the Spending Review. We will subject new levies to enhanced scrutiny and ensure they represent value for money and do not impose unnecessary costs on households and businesses.

What support is available to households requiring removal of spray foam insulation installed under government grant schemes.

In any instance where insulation is installed improperly under a government-backed scheme, consumers are entitled to remediation by their installer or, failing that, the insurance-backed guarantee. Where the measure has not been installed correctly, homeowners should contact their installer or use the TrustMark dispute resolution process to seek redress (https://www.trustmark.org.uk/homeowner/information-guidance/if-things-go-wrong). As part of the Warm Homes Plan, Government is reviewing the entire landscape - from how installers work in people’s homes to where homeowners turn for rapid action and enforcement if things go wrong. We are planning to consult on proposals for retrofit system reform early next year.

What assessment he has made of the suitability of current Seasonal Coefficient of Performance thresholds for high temperature heat pumps.

The current product standards regulations do not set distinct performance thresholds for high temperature heat pumps. The ecodesign heat pump efficiency standard applies to all heat pumps other than low temperature models. However, the government consulted in December 2024 on proposals for ‘raising product standards for space heating’. These included introducing a definition and standards for high temperature heat pumps. Under the proposals, this would be defined as any heat pump operating at 65°C flow temperature. The government will publish a response to that consultation in due course.

What assessment he has made of the effectiveness of the Microgeneration Certification Scheme regulations for heat pumps operating at flow temperatures between 65°C and 75°C.

The Microgeneration Certification Scheme (MCS) stipulates that all heat pumps operating at flow temperatures above 35°C are required to be tested and meet a Seasonal Coefficient of Performance (SCOP) of 2.8. Therefore, MCS holds heat pumps operating between 65 and 75°C to the same standards as other heat pumps. DESNZ consulted in December 2024 on “Raising product standards for space heating” which would introduce a definition and standards for high temperature heat pumps. This would be defined as any heat pump operating at 65°C. A Government Response will be issued in due course.

What steps his Department is taking to support the large scale retrofitting of heating systems in social housing.

We have committed £13.2bn in the Warm Homes Plan up to 2030, in line with our Manifesto commitment. This will support investment in low carbon heating, solar, batteries and insulation to up to 5 million homes across England. Within Wave 3 of the Warm Homes: Social Housing Fund, which launched earlier this year, in addition to targeted off-grid, low-carbon heating grant funding there is a new optional low-carbon heating funding incentive for homes on the gas grid. Up to 10% of on-grid homes in an application can access a £20,000 grant per home to install low-carbon heating measures.

What steps his Department is taking to ensure that new housing developments have sufficient grid capacity to meet net zero requirements.

To ensure there is sufficient grid capacity to meet net zero, the government is delivering a major expansion of electricity networks. We are working with Ofgem and the National Energy System Operator to speed up delivery of new network infrastructure through reforms to planning, support for communities and strategic network design. We are also working with Ofgem to ensure its price control framework supports proactive investment in the local distribution network. This will be informed by Regional Energy Strategic Plans, which will consider local requirements including ensuring timely reinforcement of networks for new housing developments.

Whether he plans to provide additional support for energy bills for people in Newbury in winter 2025.

The Government recognises that we need to support households in constituencies like Newbury and across the UK who 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 next winter, around 6 million low-income households will receive the £150 support to help with their energy bill costs.The Government has been clear with suppliers that they should do all that they can to support their customers – including vulnerable consumers – who may be struggling with their bills. I would urge any consumers who are struggling to pay their bills to speak to their supplier, local authority, or Citizens Advice who may be able to provide help and support. Your constituents in Newbury can also visit the GOV.UK website, where extra cost-of-living support can be found: www.gov.uk/cost-of-living.The Government is continuing to work with Ofgem and energy suppliers to ensure energy bills remain fair and affordable while we transition to clean power by 2030.

Whether his Department plans to work with energy suppliers to improve energy infrastructure in the South of England to enable communities near army bases to install smart meters.

The Department is not aware of any evidence that the proximity of army barracks to a premises impacts energy suppliers’ ability to install smart meters.

What assessment his Department has made of the potential impact of inadequate infrastructure near army barracks on local communities' ability to install smart meters.

The Department is not aware of any evidence that the proximity of army barracks to a premises impacts energy suppliers’ ability to install smart meters.

What assessment he has made of the potential impact of increases in energy prices on pensioners in Newbury constituency no longer receiving winter fuel payment.

Over a million pensioners will continue to receive the Winter Fuel Payment and through our commitment to protect the triple lock, those on the full new State Pension will receive a boost of over £400 – twice the average winter fuel payment. We continue to urge everyone who might be eligible for pension credit to claim so that they can also continue to receive the Winter Fuel Payment. The Department’s Warm Home Discount (WHD) provides a £150 rebate off winter energy bills for eligible low-income households. On 25 February, we published a consultation on the expansion of the Warm Home Discount, giving more eligible households £150 off their energy bills. These proposals would bring around 2.7 million households into the scheme – pushing the total number of households that would receive the discount next winter up to around 6 million. I have also worked with energy suppliers to agree a £500 million Winter Commitment to help customers struggling with bills this winter. I have been clear with suppliers that they should do all that they can to support their customers – including vulnerable consumers – who may be struggling with their bills.

What steps his Department is taking to support people in Newbury constituency with energy bills.

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. The creation of Great British Energy will help us to harness clean energy and have less reliance on volatile international energy markets and help in our commitment to make Britain a clean energy superpower by 2030. This, combined with our Warm Homes Plan to upgrade millions of homes to make them warmer and cheaper to run is how we will drive down energy bills and make cold homes a thing of the past.We are delivering the Warm Home Discount to around 3 million eligible low-income households this winter. On 25 February, we published a consultation on the expansion of the Warm Home Discount, giving more eligible households £150 off their energy bills. These proposals would bring around 2.7 million households into the scheme – pushing the total number of households that would receive the discount next winter up to around 6 million. The Government has extended the Household Support Fund in England until 31 March 2026 with an extra £742 million in support, with additional funding for the Devolved Governments. In addition, I have also worked with energy suppliers to agree a £500 million Winter Commitment to help customers struggling with bills this winter.

What steps he plans to take to support residents with recent trends in petrol prices in Newbury constituency.

The Government response to the road fuels consultation published on 30 October 2024 confirmed that Government will implement the recommendations made by the Competition and Markets Authority (CMA) to: Set up a statutory open data scheme for fuel prices, called Fuel Finder.Provide the CMA with information gathering powers – which commenced on 1 January 2025 - so it can monitor and scrutinise fuel prices. Fuel Finder will increase price transparency and help drivers easily compare prices and find the best deals. This will increase pressure on fuel retailers to compete strongly to attract customers. Subject to legislation and parliamentary timings, we aim to launch Fuel Finder by the end of 2025.

If he will make an assessment of the potential merits of introducing measures to prevent households that have chosen not to install smart meters from higher energy tariffs.

The mechanism for protecting consumers from disproportionate energy prices is the Price Cap, which ensures default tariffs are priced efficiently. This protects households who are on their supplier’s default tariff. The level of the price cap is the same for both smart and non-smart meter default tariffs.

Whether he has had discussions with energy suppliers on continuing the Voluntary Debt Commitment after winter 2023-24.

My Rt. Hon. Friend the Secretary of State and I have had regular discussions with suppliers on a range of issues, including the Voluntary Debt Commitment. Following these discussions, the Government and industry have worked together to deliver a £500m Winter Support Commitment for customers, and we applaud suppliers stepping up on this matter.

What steps his Department is taking to support people to pay their energy bills.

The Government believes that the only way to guarantee our energy security and protect billpayers permanently is to speed up the transition away from fossil fuels and towards homegrown clean energy. The creation of Great British Energy will help us to harness clean energy and have less reliance on volatile international energy markets, and help in our commitment to make Britain a clean energy superpower by 2030. In the short-term, we are continuing to deliver the Warm Home Discount which provides an annual £150 rebate off energy bills for eligible low-income households. I have met with energy suppliers and encouraged them to build on the Voluntary Debt Commitment for this winter, and we are continuing to work with suppliers to ensure consumers are supported this winter.
