As autumn deepens and the nights grow longer, many in the UK are asking the same seasonal question: when do the clocks go back? This annual time shift marks the end of British Summer Time (BST) and the return to Greenwich Mean Time (GMT) — a ritual that affects everything from your morning routine to the amount of daylight we enjoy each day.
According to the BBC Weather report, the clocks go back one hour at 2 a.m. on Sunday, October 27, 2025. That means an extra hour in bed for most people — but also earlier sunsets and darker evenings as the nation transitions into wintertime.
Why Do the Clocks Go Back?
The tradition of changing the clocks dates back over a century. The UK first introduced daylight saving time during World War I to conserve energy by making better use of daylight hours. Since then, it’s become a biannual habit — clocks go forward one hour in spring (“spring forward”) and back one hour in autumn (“fall back”).
The primary goal remains the same: to make the most of natural daylight, reduce energy consumption, and improve productivity during the day. However, the debate continues about whether the system is still relevant in today’s modern, energy-efficient world.
When Do the Clocks Go Back This Year?
This year, clocks go back on Sunday, October 27, 2025, at 2 a.m., reverting to 1 a.m. GMT.
Here’s what it means for you:
- You’ll get an extra hour of sleep that night.
- Mornings will be slightly lighter, making early starts a little easier.
- Evenings will become noticeably darker earlier — expect sunset before 5 p.m. in many parts of the UK by early November.
For those wondering when do the clocks go back and what impact it will have, this change officially marks the beginning of standard time, which will last until the clocks go forward again in March 2026.
How to Prepare for the Time Change
The good news is that most modern devices — smartphones, tablets, computers, and digital clocks — will automatically adjust when the clocks go back. However, you might still need to manually change traditional watches, wall clocks, oven timers, or car clocks.
Here are a few quick tips to make the switch smooth:
- Change your clocks before bed on Saturday night to avoid confusion.
- Take advantage of the extra hour by resting — the darker evenings ahead can disrupt sleep patterns.
- Be cautious on the roads — studies show that road accidents tend to increase during the first week after the time change due to darker evenings and driver fatigue.
Why the Clock Change Still Matters
While some countries have abolished seasonal clock changes, the UK continues the practice in line with European norms — at least for now. Many experts argue that longer daylight in the morning helps improve safety, productivity, and mental health during darker months.
However, others question whether changing the clocks still makes sense in a 24-hour economy. Critics suggest that the disruption to sleep schedules and body rhythms can negatively affect wellbeing and concentration, especially for shift workers and children.
Nevertheless, the phrase “when do the clocks go back” remains one of the most searched terms in the UK every October, as millions prepare to reset their daily routines.
Looking Ahead: When Do Clocks Go Forward Again?
Once the clocks go back on October 27, the UK will remain on Greenwich Mean Time (GMT) until spring. The next change — when the clocks go forward again — is set for Sunday, March 30, 2026, when British Summer Time resumes.
So, if you’re planning events, travel, or simply want to stay on schedule, mark those dates in your calendar now.
A Small Change With a Big Impact
Though the adjustment may seem minor, it signifies a bigger seasonal shift — shorter days, cooler weather, and the start of the winter season. From heating schedules to outdoor activities, the time change touches nearly every part of daily life in the UK.
So when someone asks “when do the clocks go back?”, remember: it’s not just about resetting the time — it’s a reminder to slow down, cozy up, and embrace the season ahead.
