The end of October brings more than just autumn leaves and Halloween preparations. It marks the conclusion of British Summer Time (BST), when clocks across the UK “fall back” one hour. This twice-yearly ritual affects millions of people, yet many still find themselves confused about when it happens and why we do it at all.

Understanding when the clocks change helps you prepare for the transition and make the most of that extra hour. Whether you’re planning your weekend or simply want to avoid being an hour early (or late) for Monday morning commitments, this guide will walk you through everything you need to know about the end of British Summer Time.

The clock change also brings practical considerations for your daily routine, sleep schedule, and even your garden. Let’s explore how this age-old tradition works and how you can navigate the transition smoothly.

What Is British Summer Time?

British Summer Time is the practice of advancing clocks by one hour during the warmer months. This system runs from the last Sunday in March until the last Sunday in October, giving us longer daylight hours in the evening during spring and summer.

When BST begins in March, we “spring forward” by moving clocks ahead one hour at 1am, which becomes 2am. The reverse happens when BST ends in October—clocks “fall back” from 2am to 1am, giving us an extra hour.

This system means we experience Greenwich Mean Time (GMT) during winter months and BST during summer months. The change affects everything from sunrise and sunset times to your daily schedule, making it important to understand when these transitions occur.

When Do the Clocks Go Back in 2025?

The clocks go back on 2am on Sunday, 26 October. At this exact moment, clocks automatically return to 1am, marking the official end of British Summer Time.

This date follows the established pattern of the last Sunday in October. Most digital devices, including smartphones, computers, and modern clocks, will adjust automatically. However, traditional analog clocks, car clocks, and some older devices require manual adjustment.

The timing remains consistent—always at 2am on the designated Sunday. This early morning timing minimises disruption to daily activities and transport schedules.

Why Do the Clocks Go Back?

The practice of changing clocks twice yearly stems from a desire to make better use of natural daylight. During summer months, advancing clocks means more daylight in the evening when most people finish work and engage in leisure activities.

By moving clocks forward in spring, we effectively shift an hour of morning daylight to the evening. This creates longer, brighter evenings perfect for outdoor activities, gardening, and socialising. When autumn arrives and daylight hours naturally decrease, we return to standard time.

The system originated during World War I as an energy conservation measure. The idea was that longer daylight hours in the evening would reduce the need for artificial lighting, saving coal and electricity. Germany first implemented the practice in 1916, with Britain following shortly after.

While modern energy usage patterns differ significantly from the early 20th century, many countries continue the practice. Some research suggests modest energy savings still occur, though the benefits are debated among economists and energy experts.

Preparing for the Clock Change

The transition back to GMT offers a rare opportunity to gain an extra hour, but it requires some preparation to maintain your routine smoothly.

Update Your Clocks
Begin by identifying which clocks in your home need manual adjustment. While smartphones, tablets, and computers typically update automatically, check your:

  • Kitchen and bedroom clocks
  • Car dashboard clock
  • Oven and microwave displays
  • Traditional watches
  • Garden clocks and timers

Adjust Your Sleep Schedule
The extra hour might seem like a bonus, but it can disrupt your sleep pattern. Help your body adjust by maintaining consistent bedtime and wake-up times in the days following the change. Expose yourself to natural light in the morning to help reset your internal clock.

Check Scheduled Commitments
Review your calendar for the Monday following the clock change. Ensure you understand whether appointments use GMT or still reference BST. Most UK businesses and services automatically adjust, but international calls or meetings might require clarification.

Managing the Seasonal Transition

The end of British Summer Time coincides with shorter daylight hours and the approach of winter. This seasonal shift affects more than just your clocks—it impacts your daily routine, mood, and activities.

Embracing Earlier Sunsets
While losing evening daylight can feel disappointing, shorter days create opportunities for cosy indoor activities. Consider this the perfect time to start autumn projects, catch up on reading, or begin planning for the festive season.

The earlier darkness also makes it easier to establish evening routines. With sunset occurring around 5pm by late October, you can create a natural wind-down period that supports better sleep.

Garden and Outdoor Considerations
Your garden will benefit from some attention before winter sets in. The clock change serves as a helpful reminder to complete autumn tasks:

  • Clear fallen leaves from lawns and paths
  • Plant spring bulbs before the ground freezes
  • Protect tender plants from frost
  • Clean and store garden furniture
  • Check outdoor lighting for the darker evenings ahead

Supporting Local Wildlife
As daylight hours shorten, wildlife prepares for winter. You can help by maintaining bird feeders, leaving areas of long grass for insects, and ensuring any garden ponds remain accessible. These small actions support the natural ecosystem during the challenging winter months.

The Ongoing Debate About Clock Changes

The twice-yearly clock change remains controversial. Some argue the practice is outdated and causes more disruption than benefit in our modern society. Others maintain that the seasonal adjustment helps us make better use of natural daylight.

The European Union voted in 2019 to end mandatory clock changes, though implementation has been delayed. Individual member countries would choose whether to remain permanently on summer time or winter time. The UK, having left the EU, continues to evaluate its own policy independently.

Arguments against clock changes include increased risk of accidents, sleep disruption, and minimal energy savings. Supporters emphasise the mental health benefits of lighter evenings and the continuation of a long-standing tradition.

Making the Most of Your Extra Hour

When the clocks go back, you gain a precious extra hour on Sunday morning. Rather than simply sleeping longer, consider using this time purposefully.

Use the extra hour to establish a calming morning routine. Enjoy a leisurely breakfast, spend time in your garden, or tackle a small project you’ve been postponing. This approach helps you feel productive while adjusting to the time change.

The additional daylight in the morning also creates perfect conditions for outdoor activities. Take an early walk, do some garden maintenance, or simply appreciate the autumn colours in your local area.

Looking Forward to Spring

While the end of British Summer Time marks shorter days ahead, it also begins the countdown to spring’s return. The clocks will spring forward again on the last Sunday in March 2026, bringing back those longer, lighter evenings we associate with warmer weather.

Until then, embrace the rhythm of shorter days and longer nights. Use this period to focus on indoor projects, spend quality time with family and friends, and prepare for the festive season ahead.

Remember that every season brings its own pleasures and opportunities. The end of British Summer Time simply marks another natural transition in our yearly cycle, offering a chance to slow down and appreciate the changing world around us.
