What funding his Department plans to allocate to Phase 4 of the Energy Company Obligation 4 (ECO4) scheme.

ECO4 is not a Government funded scheme, but a legal obligation placed on energy suppliers to delivery energy efficiency support to eligible households. The obligated suppliers fund the upfront costs of those installations and recoup the funds through their domestic consumers’ energy bills under the energy price cap. The legal obligation is divided across energy suppliers and based on their respective shares of the domestic gas and electricity market. Energy suppliers are permitted to deliver their obligation at their preferred pace throughout the scheme. The total value of ECO4 is £4 billion across the four years of the scheme.

How many acres of agricultural land of (a) Grade 1, (b) Grade 2, (c) Grade 3a and (d) Grade 3b have had planning applications for energy projects, including related, incidental, or facilitative infrastructure, approved since 5 July 2024; and if he will provide details of the acreages per land grade for each energy technology.

The Department does not hold the data requested, but when each individual planning decision is made, the information about the extent and grade of any agricultural land being utilised is set out in as part of the published decision. The revised National Planning Policy Framework, which was published on 12 December 2024, is clear that where significant development of agricultural land is demonstrated to be necessary, areas of poorer quality land should be preferred to those of a higher quality. This will, where relevant, be a material consideration in planning decisions, including those made by the Secretary of State.

Whether households with existing underfloor foam insulation are eligible for funding through the Energy Company Obligation 4 (ECO4) scheme.

Households with existing underfloor foam insulation may be eligible for Energy Company Obligation 4 (ECO4) scheme support if they meet scheme eligibility criteria. Homes equivalent to Energy Performance Certificate (EPC) bands D-G, for owner occupied households, and bands E-G for privately rented homes and social housing, where occupants are in receipt of means-tested benefits, are eligible for the scheme, as well as those referred by their local authority under ECO Flex. However, meeting the eligibility criteria does not guarantee assistance. This is determined by obligated suppliers and the installers to whom they sub-contract.

How much funding remains available in Phase 3 of the Energy Company Obligation 4 (ECO4) scheme.

ECO4 funding is not released through a tranche system. The scheme sets a legal obligation on energy suppliers, and this is divided between energy suppliers based on their respective shares of the domestic gas and electricity market. Energy suppliers are permitted to deliver their obligation at their preferred pace over the life cycle of the scheme, between April 2022 and March 2026. The total value of ECO4 is £4 billion. This breaks down to £1bn a year for the four years of the scheme.

What steps his Department is taking to help prepare households for the closure of the radio teleswitch service in June 2025.

The Radio Teleswitch Service (RTS) is an industry-led initiative, with the switch-off being overseen by the energy industry, Energy UK and Ofgem. I recently met with Ofgem and Energy UK to discuss plans for the switch-off. I will continue to meet them regularly to track progress. Ofgem and Industry have convened a Taskforce involving energy suppliers, network operators, consumers groups and the Government, to coordinate activities to rapidly increase the pace of RTS replacements. A new campaign has launched highlighting the need for RTS customers to book a meter replacement as soon as their energy supplier contacts them.

Whether his Department plans to provide funding to households that cannot afford to replace their total heating total control heating system when it stops working following the closure of the radio teleswitch service in June 2025.

The Department is aware of the complexity of a Total Heating Total Control (THTC) metering system and the tariff requirements of customers with such a system installed. Energy suppliers are best placed to advise on suitable replacement systems and tariffs for their customers, and Ofgem has been clear that suppliers must take all reasonable steps to ensure former RTS consumers stay on a closely equivalent tariff.

What steps his Department is taking to help support households in rural areas in Scotland that do not have a (a) mobile and (b) radio signal and cannot install a smart meter in advance of the closure of the radio teleswitch service in June 2025.

Where a household is one of the 0.7% of premises in Great Britain without Wide Area Network (WAN) coverage, energy suppliers can provide pre-configured smart meters, which operate like analogue meters, until a WAN connection can be established. The Office for Gas and Electricity Markets (Ofgem) has been clear that energy suppliers are obligated under their licence conditions to ensure that a suitable metering system is installed, and that the customer's heating and hot water is not disrupted.

What the potential cost to the public purse is of the Government’s international climate finance commitments since July 2024; and if he will make an assessment of the potential impact of this spending on the funding available for energy infrastructure projects.

The Government has made a number of spending commitments since July to deliver the UK’s pledge, announced in 2019, to spend £11.6 billion in International Climate Finance (ICF) between April 2021 and March 2026. The £11.6 billion commitment is from the UK’s Official Development Assistance budget, currently set on a temporary basis at 0.5% per cent of Gross National Income.

What assessment he has made of the effectiveness of the smart meter network in North East Scotland.

The Government recognises that too many households across GB are currently unable to send automatic readings to their energy suppliers, including meters without access to WAN coverage. We will set out new plans to improve the rollout and the consumer experience, alongside Ofgem, in due course.
