Written questions by Mierlo.

What assessment his Department has made of the trends in the level of petrol and diesel prices within regions; and what steps he is taking to ensure consistent pricing for consumers.

Fuel markets are governed by competition and consumer law, overseen by the Competition and Markets Authority (CMA). The Government and the CMA are closely monitoring petrol and diesel prices in light of instability in the Middle East, and the Chancellor of the Exchequer and my Rt hon Friend the Secretary of State recently met with fuel retailers to set out a clear message: unfair practices will not be tolerated. We are also engaging regularly with refiners, importers and distributors to ensure any emerging risks are identified and managed promptly. The government has also introduced the statutory Fuel Finder scheme, which will increase transparency for UK road fuel prices, including providing localised data for prices across the UK, and the CMA have the power to take enforcement action for non-compliance.

What estimate he has made of future energy requirements for AI; and what steps he is taking to meet those requirements.

The Department’s energy and emissions projections include growth in power demand from computing services like data centres. To ensure a comprehensive view of the system, the methodology projects at a broader sector level, not disaggregating specific estimates for data centres. The Government is committed to ensuring electricity networks can meet rising electricity demand, including from data centres, by deploying new renewable and low-carbon generation in line with the Clean Power 2030 Action Plan. The Capacity Market ensures supply continuously meets demand, balancing cost and reliability to maintain adequate electricity security.

What estimate he has made of the volume of Russian oil transported through the English Channel by UK‑sanctioned tankers in the last 12 months.

Deterring and disrupting the Russian shadow fleet is a priority for the UK, and the UK Government will continue to proactively monitor tanker activity to ensure the safety of seafarers, protect the marine environment, and for national security purposes. The volume of Russian oil transiting the English Channel is not data the Department for Energy Security and Net Zero owns.

What steps his Department is taking to ensure that climate adaptation is considered alongside decarbonisation in policy planning; and whether his Department plans to develop and publish a National Climate Resilience Plan that incorporates nature-based solutions, updates infrastructure standards, provides support for local authorities and promotes public awareness through a coordinated strategy to manage climate-related risks.

Defra is the lead department for domestic adaptation to climate change, responsible for coordinating requirements set out in the UK Climate Change Act 2008. This includes preparing a UK Climate Change Risk Assessment every five years, followed by a National Adaptation Programme (NAP), setting out actions by relevant government departments to address the risks identified in the latest risk assessment. The next NAP will include local climate adaptation and support public awareness of climate risks. While Defra coordinates this work, this is a whole of government effort. In DESNZ, we are working to ensure that homes are fit for the future and the Department has been carrying out research to respond to the relevant climate change adaptation risks identified by the third Climate Change Risk Assessment. This research is closing evidence gaps identifying the buildings most vulnerable to extreme heat and where these are located, as well as appropriate adaptation solutions. This is informing the development of the Warm Homes Plan which will be published soon. Maintaining a secure and resilient energy supply is also a top priority. We work continually with industry to improve and maintain the resilience and security of energy infrastructure, considering a range of evolving risks and hazards as well as future system changes – including changing climate. This includes publishing an Energy Resilience Strategy in 2026, setting out Government’s long-term priorities to maintain energy resilience now and in the future.

If he will set and publish plans for ensuring that the most disadvantaged people can transition to clean energy with the Clean Power plan.

Last December, the Government published the Clean Power 2030 Action plan. The Plan provides the foundation for the UK to build an energy system that can bring down bills for households and businesses for good, including those who are most disadvantaged. We are also delivering improvements to home energy efficiency through a number of targeted schemes including the Warm Homes: Social Housing Fund and Warm Homes: Local Grant, which support low income and fuel poor households, alongside the continuation of the Boiler Upgrade Scheme which is providing grants to thousands of households to help upgrade their heating systems. As more homes are made energy efficient this will reduce carbon emissions, reduce overall energy demand and reduce energy bills for consumers. We will share more details on our plans to upgrade up to 5 million homes across the country as part of our upcoming Warm Homes Plan to cut energy bills for good. At almost £15bn, the Warm Homes Plan is the single biggest public investment programme in energy efficiency in UK history. We will publish more details soon.

What steps he is taking to improve energy security and ensure that households reduce energy demands.

The Government is reducing dependency on volatile fossil fuel markets, with investment in homegrown energy. The Clean Power 2030 Action Plan estimates £40 billion per year for clean energy projects, with significant upgrading of a dysfunctional grid system, ending delays by expanding the renewable auction process, and speeding up planning decisions to prioritise critical infrastructure. To reduce energy demands the government announced an additional £1.5 billion for the Warm Homes Plan, bringing total investment to almost £15 billion. This major step forward in the government’s plans will upgrade millions of homes over this Parliament and cut bills for good.

What estimate he has made of the current costs of energy per Kw/h compared to other European countries.

The Department publishes bi-annual statistical tables comparing the UK’s gas and electricity prices to the price of countries in the European Union. International energy price comparison statistics - GOV.UK These are provided in pence per kWh and are aggregated by consumption bands both including and excluding taxes. Separate tables are provided for domestic and non-domestic consumers. The prices are derived by taking the total of the monetary value of energy consumed divided by the total volume of energy. Therefore, these are representative of average prices and are not disaggregated by unit rate and standing charge.

What steps is he taking to ensure the transition to green energy is cost efficient for (a) his department with i. transmission systems, ii. distribution systems and iii. energy sources, and (b) consumers with i. heat pumps, ii. EV chargers and iii. insulation.

Network regulation is a matter for Ofgem, who regulates network operators through a price control process. Government supports Ofgem in developing a price control that delivers the transition to clean energy, while maximising value for money for consumers. Ofgem has a duty to protect the interests of consumers, whilst maintaining the financial stability and resilience of the transmission and distribution network operators. As all households move towards clean heat technologies, low income and fuel poor households will need more support to enable them to make greener choices. Government is focused on incentivising moves to cleaner, affordable heating and making this attractive and easy for the public. Our Warm Homes Plan will support investment in heat pumps and other energy efficiency upgrades to help cut bills.

What steps he is taking to ensure that local authorities have a clear process to follow for shared ownership and community benefit clean energy planning permission.

In the Clean Power Action Plan, we made it clear that where communities host clean energy infrastructure they should feel tangible and enduring benefit of doing so. Shared ownership plays a key role in ensuring all communities can share the benefits from the transition to net zero 2050.We are in the process of reviewing responses to our recent working paper and will continue to explore the role of local authorities in community benefit funds and shared ownership opportunities.

What assessment he has made of the adequacy of the Clean Power plan for helping those in fuel poverty and those currently using gas boilers in transitioning to clean greener energy.

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 2025, 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. We are also delivering improvements to home energy efficiency through a number of schemes including the Warm Homes: Social Housing Decarbonisation, Warm Homes: Local Government and the continuation of the Boiler Upgrade Scheme, which is supporting thousands of households to upgrade their heating systems. As more homes are made energy efficient this will reduce carbon emissions, reduce overall energy demand and reduce energy bills for consumers.

Whether he has made an assessment of the potential merits of revising the compensation scheme for electricity consumers to include compensation for the inconvenience caused by power cuts of shorter duration where these occur repeatedly.

The Government expects energy companies to deliver the best support to customers. Ofgem monitors and enforces the Guaranteed Standards of Performance. Ofgem also regularly reviews and updates their compensation arrangements. The most recent changes were made following the Storm Arwen Review which came into effect on 1 September 2023 and enable higher levels of compensation at more regular intervals. Ofgem regulates Distribution Network Operators through a price control process, which includes incentives to reduce the frequency and duration of power interruptions. For the next price control period (2028–2033), Ofgem is reviewing whether amendments are required to minimise repeated or prolonged interruptions.

What steps he is taking to help (a) ensure that energy consumers receive a reliable electricity supply and (b) reduce power cuts due to issues with the electricity distribution network.

Maintaining a secure electricity supply is a key priority for Government. DESNZ works closely with industry to continually improve and maintain the resilience the energy infrastructure, networks and assets to reduce vulnerabilities, and ensure an effective response to actual or potentially disruptive incidents. Ownership of a Distribution Network Operator (DNO) requires appropriate levels of investment to ensure power flows reliably, safely and securely. All DNOs are regulated by Ofgem, which sets annual targets for customer interruptions and customer minutes lost; DNOs must report their performance against these measures to Ofgem which rewards or penalises operators appropriately.

What steps he is taking to ensure sufficient energy supply to meet demand in the next 10 years.

Great Britain is expected to have sufficient supplies of electricity and gas to meet consumers’ demands over the short and long-term (Statutory Security of Supply Report 2024). The government’s mission is to secure our energy supply with home-grown, clean power – and we have set out the steps to achieve this in the Clean Power 2030 Action Plan. These include: cleaning up a dysfunctional grid system by prioritising the most important projects; speeding up decisions on planning permission by empowering planners to prioritise critical energy infrastructure; and expanding the renewable auction process to stop delays and get more projects connected.

If he will make an assessment of the potential merits of extending the boiler upgrade scheme to include (a) heat batteries and (b) other low carbon heating technologies.

The Government is committed to incentivising properties to transition to cleaner, affordable heating. At present, the Boiler Upgrade Scheme, does not apply to alternative electric heating technologies, such as heat batteries. We are targeting support at technologies, like heat pumps, that current evidence suggests offer the greatest potential to decarbonise our buildings. However, the Government will keep its position on alternative electric heating technologies under review and make further assessments as the evidence base develops. Our Warm Homes Plan will offer grants and low interest loans to support investment in low carbon heating and other home improvements to cut bills.

What his planned timetable is for adopting Standard Assessment Procedure 10.2, in the context of the Home Upgrade Grant 2 project; and whether residents that have missed out on solar batteries will be able to apply for their system to be upgraded.

We are introducing improvements to Energy Performance Certificate (EPC) modelling in early 2025, known as Reduced Data Standard Assessment Procedure 10 (RdSAP 10), to improve accuracy. EPC assessors will soon be able to record if a consumer has installed solar batteries. The Home Upgrade Grant (HUG 2) will run until March 2025 and will be succeeded by the Warm Homes: Local Grant (WH:LG). Details of the policy on retreating low-income households that received upgrades under HUG 2 were published on 23rd September as part of the WH:LG guidance.
