UK Clocks Went Back on 25 October: What Happens After British Summer Time
The UK returned to Greenwich Mean Time in the early hours of Sunday 25 October 2026, when clocks moved back by one hour. Here is what changed and the next key date.

The clocks went back by one hour across the United Kingdom on Sunday 25 October 2026, bringing British Summer Time (BST) to an end and returning the country to Greenwich Mean Time (GMT).
The change happened at 2am BST, when the time moved back to 1am GMT. The extra hour meant that the same hour of the night occurred twice, a small adjustment with practical consequences for journeys, appointments and devices that keep time.
The date and the precise clock change are confirmed by the UK government’s published timetable. Both the Royal Observatory Greenwich and the independent timeanddate.com timetable confirm the same 2026 date and the 2am-to-1am change.
Why the clocks change
The UK observes British Summer Time in the lighter months, moving the clocks one hour ahead of GMT in spring. In autumn, the clock moves back and GMT is used through the winter.
The system redistributes daylight across the day rather than creating any extra daylight. Once the clocks return to GMT, sunrise and sunset occur about an hour earlier by the clock than they did immediately beforehand. People may notice brighter mornings but darker late afternoons.
The transition normally takes place on the last Sunday in October, while the forward move occurs on the last Sunday in March. The system is longstanding, and the 2026 change was scheduled rather than a surprise policy decision.
Do phones change automatically?
Most modern smartphones, computers and connected devices adjust automatically when their time settings are correct. But wall clocks, analogue watches, some car dashboards and household appliances may need to be changed by hand.
People travelling overnight or using timetable-based services should confirm the local departure time with the transport operator. Any appointment scheduled during the repeated hour may also need a clearer reference to BST or GMT to avoid ambiguity.
The change does not mean that working hours, shop opening times or train schedules automatically shift by an hour in their published local time. Instead, the relationship between the clock and daylight changes, while services continue to state times in the local time zone.
When will the clocks go forward again?
The next scheduled move in the UK is Sunday 28 March 2027, when clocks will go forward by one hour. The government’s online table also confirms that date.
There has long been debate about whether the twice-yearly switch should continue, but the date on its own should not be confused with a new legislative decision about daylight saving.
For the remainder of autumn and winter, the UK is on GMT. Anyone checking the time of a meeting involving people in other countries should account for the fact that different territories change their clocks on different dates, or do not use seasonal clock changes at all.
For the simplest answer to the question being searched today: yes, the UK clocks have gone back, and the change occurred in the early hours of 25 October 2026.
