The question

To ask the Secretary of State for Energy Security and Net Zero, 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.

Answered by Miatta Fahnbulleh

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.
