What assessment he has made of the potential impact of the closure of the Strait of Hormuz on (a) oil prices and (b) the economy.

Oil and gas markets are well supplied and functioning normally. Though they have responded to events in the Middle East, prices remain within the bounds we have seen over the last year. We have not witnessed any material reduction of traffic passing through the Strait of Hormuz. DESNZ will continue monitoring closely for any future impacts. The Government's Clean Energy Superpower Mission, supported by the largest investment in home-grown clean energy in British history, will enhance energy security by boosting our energy independence, protecting billpayers, and reducing exposure to global supply shocks.

What steps he is taking to ensure a gas supply at MBR Acres in Wyton in Cambridgeshire.

The Department is aware of concerns regarding the continuity of supply of LPG to MBR Acres in Wyton due to ongoing protests and the potential impact on the delivery of liquefied petroleum gas. We have and are continuing to engage cross-government as well as with LPG suppliers to ensure that lawful supply chains can continue to operate safely.

Pursuant to the Answer of 29 May 2025 to Question 53710 on Private Rented Housing: Energy, how the total undiscounted capital expenditure required to meet the standards was calculated.

DESNZ’s National Buildings Model, which is based on a representative sample of properties in England, was used to simulate landlords installing measures to bring their properties up to the proposed standards. For the preferred consultation option, the measures that landlords were modelled to install by 2030 are shown in Table 5 of the Options Assessment. The total undiscounted capital expenditure incurred by landlords is based on summing the costs of installing all measures, using measure cost assumptions that are based on a range of evidence sources. Undiscounted means that costs are not discounted over time with a social discount rate.

With reference to the press release entitled Warm homes and cheaper bills as government accelerates Plan for Change, published on 7 February 2025, what estimate he has made of the number and proportion of remaining properties not at energy performance certificate level C that will not be able to be upgraded to that level owing to the nature of the property.

As outlined in the consultation-stage Options Assessment (DESNZ001(OA)-25-NZBI), there are 5.1 million privately rented properties in England and Wales, with 55% below the current EPC C. Under the preferred option, 2.8 million properties could reach the proposed new EPC C standard by 2030. Some properties may remain below standard as the consultation proposed a range of exemptions for those unable to reach EPC C. Government is currently analysing responses to decide on a final policy outcome and will publish a government response and further impact assessment in due course.

With reference to the press release entitled Warm homes and cheaper bills as government accelerates Plan for Change, published on 7 February 2025, what assessment he has made of the feasibility of upgrading the 52% of rented homes in England that are not already at Energy Performance Certificate C level.

The recently closed consultation proposed new minimum energy efficiency standards for private rented homes and was accompanied by an options assessment. We have engaged widely with stakeholders during the consultation process and will use this feedback to inform the Government’s response to the consultation, which will be published in due course with a further impact assessment.

With reference to his Department's press release entitled Warm homes and cheaper bills as government accelerates Plan for Change, published on 7 February 2025, how the figure of the average cost to landlords of complying with the proposals to upgrade their properties was calculated.

Estimates were provided in the consultation stage Options Assessment (DESNZ001(OA)-25-NZBI). The average cost to landlords of complying with the proposals to upgrade their properties was calculated by dividing the total undiscounted capital expenditure required to meet the standards by the number of properties upgraded. Figures are rounded to the nearest hundred.

With reference to his Department's press release entitled Warm homes and cheaper bills as government accelerates Plan for Change, published on 7 February 2025, what assessment he has made of the potential impact of extending the upgrading of rented homes to Energy Performance Certificate C on housing supply.

The Government recently consulted on increasing minimum energy efficiency standards in the domestic private rented sector. The consultation included proposals for rented homes to achieve Energy Performance Certificate C or equivalent by 2030 and was accompanied by the Department’s impact assessment. The assessment makes clear that we are unable to quantify the extent to which this will impact the supply of properties, as landlords may take different approaches and the policy is not yet finalised. The consultation closed on the 2nd May and we are currently reviewing responses and supporting evidence. Following this, a government response and further impact assessment will be published.

Pursuant to the Answer of 9 April 2025 to Question 43313 on Energy: Land Use, what definition he uses for the most appropriate areas, in that context.

What the maximum amount of best and most versatile land is that could be (a) used in a solar farm development designated as NSIP and (b) granted a Development Consent Order.

There is no set maximum amount of best and most versatile land that may be used in a nationally significant infrastructure development. Each case is judged on its own merits in line with the requirements in the Planning Act 2008 and relevant policy, such as the National Policy Statement for Renewable Energy Infrastructure (EN-3) which states at 2.10.29: “Where the proposed use of any agricultural land has been shown to be necessary, poorer quality land should be preferred to higher quality land avoiding the use of Best and Most Versatile agricultural land where possible”, and at 2.10.30: “Whilst the development of ground mounted solar arrays is not prohibited on Best and Most Versatile agricultural land, or sites designated for their natural beauty, or recognised for ecological or archaeological importance, the impacts of such are expected to be considered”.
