Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the proportion of privately rented non-domestic buildings in England and Wales with a total useful floor area of less than 1,000 square metres.

Based on analysis of Non-Domestic National Energy Efficiency Data-Framework 2025, we estimate that approximately 93% of non-domestic buildings have a floor area of less than or equal to 1,000 square meters. The non-domestic PRS MEES Impact Assessment will be published in due course.
