At 2:00 am GMT on Sunday, London, the United Kingdom will turn its clocks back one hour, officially ending British Summer Time and reverting to Greenwich Mean Time. The shift, mandated by the UK Government via its gov.uk time‑keeping portal, affects every corner of England, Scotland, Wales and Northern Ireland.
Why the Change Matters
Even though rolling the hands backward feels like a minor tweak, it reshapes daily routines. Sunrise on 26 October 2025 will occur around 8:06 am in London, an hour earlier than the previous day, giving commuters a few extra minutes of daylight before work. On the flip side, evening light disappears sooner, nudging families to finish outdoor activities earlier. As the Royal Observatory Greenwich explains, "when we ‘fall back’ we move an hour of sunlight from the evening to the morning, which can feel like a sudden jump into autumn".
Historical Roots of the Time Shift
The idea traces back to William Willett, a builder‑turned‑advocate who penned *The Waste of Daylight* in 1907. He argued that "shifting the clocks would save evening light for recreation and commerce." Parliament took the notion seriously during World War I, and the British Summer Time Act of 1916 codified the practice. Since then, the nation has largely kept to a predictable schedule, with only a handful of wartime exceptions.
2025 Clock Change Timeline
- 30 March 2025 – Spring forward: At 1:00 am GMT clocks jumped to 2:00 am BST, adding an hour of evening light.
- 26 October 2025 – Autumn fall back: At 2:00 am BST clocks revert to 1:00 am GMT, advancing sunrise.
- 29 March 2026 – Next spring forward: Scheduled at 1:00 am GMT.
- 25 October 2026 – Next autumn fall back: Scheduled at 2:00 am BST.
These dates come straight from the UK Government’s official timetable, ensuring retailers, transport operators and schools can plan ahead.
Impact on Everyday Life
For commuters, the extra morning light can shave a few minutes off the rush‑hour commute, especially on routes that rely on daylight for safety. Farmers in the countryside often welcome the earlier sunrise, allowing more time for livestock checks before the day truly begins. Conversely, the hospitality sector reports a dip in evening foot traffic after the clocks revert, prompting some pubs and restaurants to extend their opening hours artificially.
"I set my alarm for 6:30 am now, and I actually see the sun when I leave the house," said Emma Hughes, a shop assistant from Manchester. "It feels a bit colder, but I like that I don’t have to rush in the dark."
Expert Take on the Seasonal Shift
Dr. Alan McIntyre, a chronobiology researcher at the University of Edinburgh, notes that the autumn rollback aligns better with our natural circadian rhythms. "Our bodies are primed for earlier sunrises in fall, which can improve sleep quality," he explains. However, he warns that the sudden loss of evening light can amplify seasonal affective disorder (SAD) for vulnerable individuals.
Looking Ahead: Will Britain Keep DST?
Debate over daylight‑saving time is far from settled. In 2022, the UK Parliament entertained a petition to keep the country on permanent BST, arguing it would boost tourism and reduce energy use. The proposal stalled, but advocacy groups such as Time Save the Nation continue to lobby. Should legislation change, future clock adjustments could look very different.
Key Facts
- Fall‑back occurs at 2:00 am BST on 26 Oct 2025, reverting to 1:00 am GMT.

- British Summer Time was introduced in 1916 after a 1907 proposal by William Willett.
- The UK’s time‑change schedule is set by the UK Government and published on gov.uk.
- Experts say the shift can improve sleep but may increase SAD symptoms.
Frequently Asked Questions
How will the clock change affect people who work night shifts?
Night‑shift workers will experience a one‑hour shift in their scheduled start times. Many employers adjust rosters to keep the same amount of sleep between shifts, but some employees may need to re‑orient their sleep patterns to avoid fatigue.
Will the time change impact public transport timetables?
Yes. Train and bus companies publish revised schedules ahead of the October rollback. Most services simply add an extra hour to the overnight timetable, ensuring connections remain reliable.
Why does the UK not keep daylight‑saving time year‑round?
Parliament has debated permanent BST, but concerns about darker winter evenings—especially for schoolchildren traveling home after dark—have kept the traditional spring‑forward/autumn‑back schedule in place.
What historical event first triggered the UK to adopt daylight saving?
The move was introduced during World War I as a way to conserve energy and make better use of daylight, formalised by the 1916 British Summer Time Act.
Are there any health benefits linked to the autumn time change?
Chronobiologists suggest that an earlier sunrise can improve melatonin regulation, helping many people experience deeper sleep. However, the loss of evening light may worsen symptoms for those prone to seasonal affective disorder.
