Written question asked by Alex Mayer (Labour) on Monday, 23 June 2025, in the House of Commons. It was due for an answer on Wednesday, 25 June 2025. It was answered by Justin Madders (Labour) on Tuesday, 1 July 2025 on behalf of the Department for Business and Trade.

Business: Summertime

Question: To ask the Secretary of State for Business and Trade, what recent assessment his Department has made of the potential merits for businesses of adopting Single/Double Summer Time.

Answer: The Government believes the current daylight-saving arrangements represent the optimal use of the available daylight across the UK. Therefore, we have no plans to introduce double summertime, permanent summertime, or other such changes which would require considerable planning and action by business. Since the Government does not intend to make changes to the existing system, we will not be conducting an assessment of the impact on businesses at this time.
