UK Clocks Go Back on 1 November 2026: What to Check

The UK clocks go back one hour at 2am on Sunday 1 November 2026, marking the end of British Summer Time. Your phone may update automatically, but manually set alarms, heating controls and appliance timers may need checking before Sunday; allow for the darker evenings when planning walks and journeys. GOV.UK confirms the date and time of the change.

When the clocks change in the UK

At 2am, clocks return to 1am. The repeated hour means Sunday is 25 hours long by the clock. If you have an early appointment, shift, train or flight, check its stated local time and the provider’s latest information rather than relying on memory.

Check alarms, heating and appliance timers

Whether a device changes automatically depends on its model, settings and how it keeps time. Check the device instructions or settings if you are unsure.

• Phones, computers and smartwatches: These usually adjust when automatic date, time and time-zone settings are enabled. Check the displayed time after the change, especially if you use an older device or have automatic settings turned off.
• Standalone alarm clocks and watches: Digital clocks without a network connection, analogue clocks and some watches may need to be reset. Check any alarm you set manually for Sunday morning.
• Heating controls: A connected thermostat may update through its app or internet connection, but schedules can depend on the controller’s clock and settings. After the change, check the displayed time and the next scheduled heating period.
• Appliances and plug-in timers: Check timers on ovens, heating appliances, lights and socket plugs. Some keep time independently and may not adjust automatically.

If a schedule matters, compare the device’s displayed time with your phone after 2am and confirm the next run time. Follow the manufacturer’s instructions before changing settings.

Plan for darker evenings and Sunday travel

The clock change does not alter the weather or road conditions, but it shifts daylight earlier by the clock and brings darker evenings sooner. If you are walking or driving later in the day, plan your route with visibility in mind and give yourself time to adjust to the change.

For travel on Sunday, check the operator’s timetable and any journey updates. This is particularly useful for services running around 1am to 2am, when the clock time repeats and schedules may need specific arrangements. Check again before setting out, and use the time shown by the relevant transport provider.
