Summertime: Energy

Question: To ask the Secretary of State for Business and Trade, what recent assessment his Department has made of the potential impact of adopting single/double summer time on levels of energy consumption.

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 single summertime, double summertime, or other such changes. Since the Government does not intend to make changes to the existing system, we have not conducted assessments of the impact on the retail and hospitality sectors, on levels of energy consumption or crime.
