The UK moved from British Summer Time to Greenwich Mean Time at 02:00 on Sunday 25 October 2026, when clocks went back one hour. The change shifts daylight relative to the clock, affecting when morning light arrives and when it gets dark in the evening. If you are planning school runs, commutes or walks this week, check sunrise and sunset times for your location before choosing when to set out.

What changed in the UK on 25 October

At 02:00, clocks went back to 01:00, ending British Summer Time and returning the UK to Greenwich Mean Time. GOV.UK says the change takes place on the last Sunday in October each year.

Most phones and internet-connected devices update automatically, but some clocks and appliances need to be changed by hand. Check any clock you rely on for an alarm, appointment or journey, especially if it does not connect to the internet. This can help avoid confusion when a manually set clock and a phone show different times.

How the clock change affects daylight

The change does not create more daylight or reduce the total daylight available. Instead, it shifts the clock labels for sunrise and sunset by about an hour compared with the previous day. The exact times vary by location and date.

In practical terms, daylight generally arrives earlier by the clock in the morning and fades earlier in the evening. A school run or commute that usually takes place in one kind of light may therefore feel different after the clocks change. The effect depends on when you travel and where you are, rather than on a single sunrise or sunset time that applies across the UK.

Cloud cover can also affect how bright a particular morning or evening feels. Sunrise and sunset times describe the local timing of daylight; they do not tell you what the weather or visibility will be on your route. Check a location-specific forecast as well if conditions matter to your plans.

Check daylight against your routine

For the week ahead, compare local sunrise and sunset times with the hours you expect to be outside. The useful question is where daylight falls in your own day: an earlier sunrise by the clock may suit an early start, while an earlier sunset may leave less daylight after work or school.

School and work journeys: Check your area’s sunrise time if you leave early, and consider how the changed light affects familiar routes.
Walks and outdoor plans: Look up the local sunset time before setting out late in the day. If you want to be back in daylight, allow enough time for your plans.
Clocks and appointments: Confirm that manual clocks, alarms and any scheduled journeys show the correct time after the switch.

For travel, follow current local conditions and information from transport operators. The clock change alone does not establish whether a particular route will be bright, clear or safe at a given time.

Find sunrise and sunset times for your location

Use a sunrise and sunset listing for your town or postcode, then compare the times with the hours you need to be outside. A national example may not match your local daylight, so avoid using one town’s times to plan another location’s morning or evening.

If you are planning further ahead, check again closer to the day: sunrise and sunset continue to change as autumn progresses. A time that fits this week’s routine may not describe the available daylight later in the season.
