UK Clocks Went Back: Check Trains, Appointments and Devices

UK clocks went back one hour on Sunday, 25 October 2026, giving people an extra hour on the clock. If you are travelling overnight, have an early appointment or use a clock that does not update automatically, check the time and any relevant timetable before setting off.

The clocks changed at 2am on 25 October

British Summer Time ended when clocks moved from 2am to 1am across the United Kingdom. The repeated hour can make the time on a clock seem out of step with travel plans or reminders made before the change.

Most internet-connected phones and computers update automatically when their time-zone settings are correct. Some watches, clocks, car displays and other devices may need to be changed by hand. Check each device you rely on rather than assuming all of them have adjusted.

Check overnight trains and appointment times

The clock change may affect how an overnight journey is shown or scheduled during the repeated hour. The details can vary by operator and route, so check the latest timetable directly with your train operator before travelling. Allow time to confirm the departure time, any connections and the time shown on your ticket or booking.

For appointments, check the confirmation and any reminders on the device you plan to use. If the appointment is early or time-sensitive, confirm its local time with the organiser and check that your alarm is set for the right time after the change.

Check device settings and the next clock change

If a device shows the wrong time, check that its date, time zone and automatic time settings are correct. For a manual clock, move the hands back one hour. If a calendar reminder looks unusual, check the event details and the device’s time-zone setting before changing the appointment itself.

GOV.UK lists Sunday, 25 October 2026 as the date the UK clocks went back. For practical plans now, the most useful checks are the current operator timetable, your appointment confirmation and the clocks or alarms you depend on.
