Question to the Department for Business and Trade:

To ask the Secretary of State for Business and Trade, pursuant to the answer of 28 November 2025, to Question 92594, on Cabinet Office: Public Expenditure, if he will publish the (a) evidential basis and (b) research underpinning the estimated regulatory cost; and whether this included assimilated EU law.

The methodology and evidence for the estimated baseline of the administrative burden of regulation on businesses of £22.4bn a year in 2024 prices is set out in the technical annex to the policy paper ‘A new approach to ensure regulators and regulation support growth’, published on 21^st October 2025.

The baseline and resulting target apply from the start of April 2025 and reflect (by the methodology stated in the technical annex) our estimates of administrative burden of all UK government regulation at the time, including assimilated EU law.
