In the UK, clocks are scheduled to go back one hour at 2 a.m. on Sunday, October 25, 2026, as British Summer Time ends and Greenwich Mean Time resumes. Sleep experts quoted by Glamour UK recommend shifting bedtime gradually beforehand and keeping consistent sleep, meal and light routines afterward; individual effects may vary.
UK clocks are due to go back one hour at 2 a.m. on Sunday, October 25, 2026, ending British Summer Time (BST) and returning the country to Greenwich Mean Time (GMT). The change gives people an extra hour by the clock, but sleep experts cited by Glamour UK say shifts in light and daily schedules can leave some people feeling tired or out of sync.
The UK’s usual seasonal schedule moves clocks forward at 1 a.m. on the last Sunday in March and back at 2 a.m. on the last Sunday in October. In 2026, the autumn change falls on October 25. At the moment of the change, clocks move back to 1 a.m., repeating that hour.
Psychologist and neuroscientist Dr Lindsay Browning, a sleep expert for And So To Bed, advises gradually shifting bedtime later in the days before the clocks change. She suggests moving it by about 15 minutes a day for two to three days, and says meal times can also be moved later to help align routines with the new time.
After the change, Browning recommends a regular bedtime and wake time throughout the week. Human biologist Gary Brecka, founder of The Ultimate Human Wellness, also advises keeping meal times consistent and avoiding late-night meals or snacks during the first three days. His further suggestions include getting outdoors in the morning and fitting in exercise. These are expert recommendations, not guarantees that everyone will adjust at the same pace.
How the Shift Can Affect Sleep
The clock change alters the stated time without immediately changing a person’s established sleep pattern. The source report explains that the body’s circadian rhythm responds to environmental cues, including daylight and meal timing. A sudden difference between those cues and the clock may be associated with grogginess, fatigue or a jet-lag-like feeling, although the effects can differ from person to person.
The practical issue is particularly relevant to people who keep fixed work, school or childcare schedules. Parents of young children may also find that familiar bedtime routines no longer line up neatly with the clock. Preparing in advance and keeping daily cues steady may help make the change easier to manage, but the cited advice does not promise to prevent sleep disruption.

The UK’s Autumn Clock Schedule
The October change marks the end of British Summer Time, the UK’s daylight-saving period, and the return to GMT. The report says the change is on the earliest possible date for 2026 because November 1 falls on a Sunday; the UK’s rule places the clock change on the last Sunday in October.
The report also notes that the clock changes are part of a seasonal practice used by many countries. Its focus here is the UK timetable and how people might adapt their sleep routines, rather than a change to the rules themselves. The date and time refer to the scheduled UK change; local schedules elsewhere can differ.
““To help your body adjust quickly to the new time, it can be a good idea to gradually alter your bedtime two to three days before the clocks change so that you get used to falling asleep and waking up later.””
— Dr Lindsay Browning, psychologist, neuroscientist and sleep expert for And So To Bed, as quoted by Glamour UK
Individual Sleep Effects Vary
The clock-change date is set out in the source report, but it does not establish how strongly the shift will affect any particular person. Sleep responses vary, and the suggested adjustments are expert guidance rather than results from a specific trial described in the report. It is also not clear how long any tiredness or disruption might last for an individual.
The report gives no detailed evidence or comparison data for the size of the effect, and does not assess whether each tip works equally well for different age groups or circumstances. Readers with persistent sleep problems or health concerns may need advice suited to their own situation rather than relying on general clock-change suggestions.
Preparing for October 25
Before the change, people who want to try the advice can shift bedtime gradually over the final two or three days, while moving meals later if that fits their routine. Afterward, the recommendations are to keep regular sleep and meal times, seek outdoor daylight in the morning and stay physically active when practical.
People can check household clocks and devices after the change, though many phones and internet-connected devices update automatically. The next scheduled seasonal clock change in the UK is the move forward by one hour on the last Sunday in March 2027. The source report does not describe any proposed change to the UK’s clock-change policy.
Key Questions
When do clocks go back in the UK in 2026?
Clocks are scheduled to go back at 2 a.m. on Sunday, October 25, 2026. The UK returns from BST to GMT, and the clock moves back to 1 a.m.
Do we gain or lose an hour?
When clocks go back, the clock hour from 1 a.m. to 2 a.m. is repeated. By the clock, this means people gain an extra hour, although it may not feel like extra sleep for everyone.
How can I prepare my sleep schedule?
Dr Lindsay Browning suggests moving bedtime later by about 15 minutes each day for two to three days before the change. She also says meal times can be shifted later to help adjust daily cues.
What habits may help after the clocks change?
The experts quoted recommend a consistent bedtime and wake time, regular meal times and morning daylight. Gary Brecka also suggests avoiding late meals or snacks during the first three days. These steps may help with adjustment but cannot guarantee an uninterrupted night’s sleep.
