When Do the Clocks Go Back in 2026?
In 2026 the clocks go back on Sunday, 25 October 2026, ending British Summer Time and returning the UK to Greenwich Mean Time.
What happens on the day
At 02:00 BST on Sunday, 25 October 2026 the clocks fall back to 01:00 GMT. You gain an extra hour in bed, and the UK is on GMT until the spring change on Sunday, 28 March 2027.
Sunrise and sunset both happen an hour earlier by the clock. In London the sun sets around 16:50 shortly after the change, compared with about 17:50 the week before.
What to check
Smartphones, laptops and tablets update by themselves. Manually set clocks, such as ovens, microwaves and some car dashboards, need adjusting, along with any timer-based heating or lighting.
If you work shifts overnight on the clock-change weekend, your shift is an hour longer in autumn and an hour shorter in spring, which matters for pay and rota planning.
Effect on international time gaps
The gap with the US east coast shrinks to four hours on this date, and returns to five hours when the US clocks go back one week later. The gap with Sydney widens to eleven hours.
