When Do The Clocks Change in the UK? October 2026 Update

The clocks in the United Kingdom are set to change on Sunday, October 25, 2026, as the country transitions from British Summer Time (BST) to Greenwich Mean Time (GMT). As of October 25, 2026, residents are reminded to turn their clocks back by one hour at 2:00 a.m., marking the official end of daylight saving time for the year.

Why it is trending now

Search interest in the clock change surges annually in late October as the public prepares for the transition to darker evenings. The shift is mandated by law to align the UK with standard time, and many individuals seek confirmation of the exact date and time to avoid confusion with appointments or travel schedules.

Key facts

• The transition occurs at 2:00 a.m. on the final Sunday of October, according to standard UK government practice.
• Most digital devices, including smartphones and laptops, will update the time automatically, as noted by general technical guidance.
• The shift results in an extra hour of sleep for the night of the transition, a common point of discussion in health-related reports from The Washington Post.
• Body clock experts, as cited in The Telegraph, suggest that even a one-hour shift can influence sleep patterns and alertness for some individuals.

Why this is trending in United Kingdom

This search is trending in the United Kingdom because the end of British Summer Time is a standardized national event that affects every household and business. As the nights grow longer, residents naturally seek information on when the shift occurs to plan their weekend activities and adjust their morning routines.

Background and context

The practice of changing clocks was established to make better use of daylight during the summer months. By moving the clocks forward in spring and back in autumn, the UK shifts an hour of daylight from the morning to the evening during the summer period. When the clocks go back in October, the UK returns to its base time zone, Greenwich Mean Time.

What happens next

After the clocks change on October 25, the UK will remain on Greenwich Mean Time throughout the winter months. The next scheduled change will occur in March 2027, when the clocks will go forward again to begin British Summer Time. Individuals are encouraged to manually check non-connected clocks, such as wall clocks or oven timers, to ensure they remain accurate.
