We’ve all been there. You wake up on a Sunday morning, stumble into the kitchen to put the kettle on, and realize the clock on the oven is suddenly an hour fast. Or slow. Honestly, it's a bit of a nightmare. Even though our phones and laptops update themselves these days, the manual clocks—the ones on the wall, the car dashboard, or that old microwave—remain stubborn relics of the past. If you're wondering about the specific moment when time change UK happens this year, you aren't alone. It is one of the most searched terms in the country twice a year, every single year, without fail.
In 2026, the clocks will go forward by one hour at 1:00 am on Sunday, March 29. This marks the start of British Summer Time (BST). We lose an hour of sleep, which is objectively terrible, but we gain those glorious long evenings where the sun doesn't set until nearly dinner time. Later in the year, the clocks will go back by one hour at 2:00 am on Sunday, October 25, returning us to Greenwich Mean Time (GMT).
Why do we keep messing with the clocks anyway?
It feels archaic. It is. The whole concept of Daylight Saving Time (DST) wasn't actually a government invention to annoy us, though it feels that way in the dark of October. It was largely championed by a builder named William Willett. Back in 1907, he published a pamphlet called The Waste of Daylight. He was an avid golfer and was reportedly annoyed that his games were cut short by the sunset. He spent a massive chunk of his life—and his own money—lobbying for the change.
Willett never actually saw it happen. He died in 1915. A year later, Germany became the first country to adopt the change to save fuel during World War I. The UK followed suit shortly after with the Summer Time Act of 1916. We’ve been toggling back and forth ever since, despite the fact that most of us no longer work in coal mines or on farms where the extra morning light was supposedly essential.
Some people argue it’s dangerous. There is a measurable spike in road accidents on the Monday after the clocks go forward in March. Why? Because we’re all tired. Sleep deprivation is a real thing, and losing even sixty minutes messes with the human circadian rhythm more than you’d think. On the flip side, the Royal Society for the Prevention of Accidents (RoSPA) has spent decades arguing that we should stay on BST all year round. They reckon the lighter evenings in winter would save lives by reducing crashes during the evening rush hour.

For the spring jump:
The when time change UK event occurs on March 29, 2026. At precisely 01:00, the time jumps to 02:00. If you are working a night shift, you might find yourself working one hour less, though you should probably check your contract on that one. Most people just sleep through it and feel slightly groggy during Sunday brunch.
For the autumn fall:
The clocks go back on October 25, 2026. At 02:00, the time reverts to 01:00. This is the "good" one. An extra hour in bed. A bit of a reprieve before the long, dark slog of a British winter sets in.
The debate that never ends
Every few years, a politician brings up the idea of scrapping the change. The European Parliament actually voted to scrap DST back in 2019, but then... well, everything else happened. Brexit happened. A pandemic happened. The plan stalled. In the UK, the debate usually splits along north-south lines. People in Scotland are generally more resistant to staying on "summer time" all year because, in the deep of winter, the sun wouldn't rise in parts of the Highlands until 10:00 am. Imagine kids walking to school in pitch-black darkness. It’s a genuine safety concern that keeps the status quo in place.
Impact on your health (and how to fix it)
Your body has a master clock called the suprachiasmatic nucleus. It’s located in the hypothalamus. It responds to light. When we artificially shift the time, we’re essentially giving the entire population a minor case of jet lag.
Researchers at the University of Colorado Boulder found that the risk of heart attacks increases by about 24% on the Monday after the spring time change. It’s wild. The reverse happens in autumn; heart attack rates actually drop slightly when we gain an hour of sleep. If you want to handle the March transition better, try going to bed 15 minutes earlier each night starting the Wednesday before the change. It sounds like something your mum would tell you, but it actually works.

Don't forget the kids. If you have toddlers, you know they don't care about "British Summer Time." They wake up when their bodies tell them to. To avoid a 5:00 am wake-up call in October, try shifting their entire routine—meals, naps, bedtime—by 10 minutes a day for the week leading up to the switch.
Myths about the time change
A lot of people think the farmers still want this. Actually, the National Farmers' Union (NFU) has been fairly neutral for years. Modern farming relies more on technology and artificial lighting than it did in 1916. The "farmers need it" argument is mostly a myth that has survived long past its expiration date.
Another weird one? That it saves a massive amount of energy. While that was the original goal during the World Wars, modern studies are inconclusive. We might use fewer lights in the evening, but we use more air conditioning in the summer or more heating in the dark mornings. It’s basically a wash.
Preparing for the transition
If you have "dumb" devices, check them before you go to bed on Saturday night. This includes:
- The clock in your car (the most common one people forget).
- Traditional watches.
- Microwaves and ovens.
- Central heating programmers.
The central heating one is a big deal. If you don't update your boiler's timer, your house might be freezing when you get up, or you'll be burning gas when nobody is home. Most modern smart thermostats like Hive or Nest will handle this automatically, but older analog dial systems won't.

The transition in March is always the hardest. The "spring forward" is a thief. To mitigate the "Monday Blues" that follow, try to get some natural sunlight as soon as you wake up on that Sunday. Open the curtains. Go for a walk. It tells your brain that the day has started and helps reset your internal clock faster.
Looking ahead to 2027 and beyond
While 2026 is the immediate concern, the pattern is predictable. The clocks always change on the last Sunday of March and the last Sunday of October.
- 2027: March 28 and October 31
- 2028: March 26 and October 29
Unless there is a massive shift in government policy—which seems unlikely given the current political climate—we’ll be doing this dance for the foreseeable future. There’s a certain comfort in the rhythm of it, even if the March shift feels like a personal insult from the universe.
Actionable steps for the 2026 time change
To make sure the 2026 when time change UK dates don't throw your life into chaos, follow this simple checklist.
- Audit your tech: Ensure your smartphone is set to "Set Automatically" in the date and time settings. Most are by default, but it’s worth a quick look.
- The Saturday Night Shift: Move your manual clocks before you go to sleep on Saturday night. Don't wait until Sunday morning when you're confused about why the 10:00 am news is already over.
- Safety Check: Use the clock change as a trigger to check the batteries in your smoke alarms and carbon monoxide detectors. It’s a life-saving habit that many fire services recommend.
- Light Exposure: On Sunday, March 29, spend at least 20 minutes outdoors. The blue light from the sun is the strongest signal for your body to adjust its sleep-wake cycle.
- Driving Caution: Be extra vigilant on the Monday morning commute following the March change. Fatigue levels are higher across the board, so keep a bit more distance from the car in front.
