UK Clocks Go Back on 25 October 2026

The UK moves from British Summer Time to Greenwich Mean Time on Sunday 25 October 2026, when clocks go back one hour. Anyone travelling early, working overnight or setting an alarm should check the time change and their transport operator’s latest timetable; service arrangements can vary.

When UK clocks change in October 2026

At 2am on 25 October, clocks go back to 1am. The change is nationwide, giving people an extra hour by the clock. GOV.UK lists the date for the end of British Summer Time in 2026. For background on Greenwich’s public clock, see how shared UK time relates to seasonal clock changes.

Check Sunday travel plans with your operator

The clock change does not mean every train, bus or other service will have a different timetable. Operators may make local changes or provide specific guidance for services running overnight, so check the relevant operator’s notices and journey planner before setting out.

For a connection around the change, check the departure and arrival times directly with each operator. Pay particular attention to services scheduled between 1am and 2am, when the clocks repeat the hour.

Set alarms and plan for overnight work

Most phones and connected devices update automatically when their time zone settings are correct. If you use a manual clock, adjust it before bed so it shows the right time in the morning. Check alarms on devices you rely on, especially if they are not connected to the internet.

People working overnight should confirm shift start and finish times with their employer. The repeated hour can affect how a shift is recorded or staffed, so follow workplace guidance rather than assuming the clock change alters the rota.

Who should check before Sunday?

A quick check is useful for anyone with an early appointment, an overnight journey, a shift spanning the clock change or plans that depend on being somewhere at a precise time. Check the operator or employer information closest to your journey or shift, since any timetable or staffing change is service-specific.
