Question to the Department for Business and Trade:

To ask the Secretary of State for Business and Trade, what assumptions his Department uses regarding cost pass-through to consumers when assessing the impact of new trade-related regulatory requirements on businesses, and whether those assumptions have been revised since the publication of the Department’s 2024 Green Book-aligned appraisal guidance.

Addressing regulatory barriers to trade can help reduce costs for UK businesses trading internationally and support economic growth. Cost pass‑through to consumers is subject to uncertainty and may differ significantly depending on market conditions, products and supply chains in scope. Reflecting the Green Book’s principles‑based approach to appraisal, which emphasises judgement and proportionality where impacts are uncertain, cost pass-through impacts are considered on a case‑by‑case basis where evidence indicates that they can be assessed.
