What Time Is It in the UK? Current UK Time & Time Zones (2026)
Anyone who has tried to schedule a call with someone in London while sitting in New York, Lagos, or Sydney has hit the same one-hour puzzle: is the UK on GMT or BST right now? The answer flips twice a year, and right now the UK is on British Summer Time (UTC+1) until the clocks fall back on 25 October 2026, per GOV.UK (official UK source). By the end, you’ll know exactly how to convert UTC to UK time — and why Britain once spent three years skipping the clock change entirely.
Current time in London: BST (UTC+1) (Timeanddate (time reference)) · UTC offset: +1 · Daylight saving: Active until 25 October 2026 (GOV.UK (official UK source)) · Next clock change: Back 1 hour on 25 October 2026 at 02:00
Quick snapshot
- The UK is currently on British Summer Time (BST), which is UTC+1 (Timeanddate (time zone reference)).
- The UK uses GMT (UTC+0) in winter and BST (UTC+1) in summer (GOV.UK (official UK source)).
- Clocks go back at 2:00 a.m. on the last Sunday of October (GOV.UK (official UK source)).
- Whether the UK will permanently keep BST or GMT after Brexit is still undecided. (Timeanddate (UK BST reference))
- A fixed “GMT” label in a converter can be off by one hour during summer; choosing “London” avoids the error (Timeanddate (UK BST reference)).
- 25 October 2026: clocks go back at 02:00 (Timeanddate (London time zone)).
- On 25 October 2026 at 2:00 a.m., BST ends and the UK returns to GMT (GOV.UK (official UK source)).
- After that, the next spring change lands on the last Sunday of March 2027 at 1:00 a.m. (GOV.UK (official UK source)).
Eleven labels cover the essentials, but the pattern is simple: the UK runs on one standard time zone with a two-season offset. What changes is the name and the hour.
| Label | Value |
|---|---|
| Current offset | UTC+1 (BST) (Timeanddate (time zone reference)) |
| Winter offset | UTC+0 (GMT) (GOV.UK (official UK source)) |
| Current time zone name | British Summer Time (Timeanddate (BST reference)) |
| Winter time zone name | Greenwich Mean Time (Timeanddate (time zone reference)) |
| Spring 2026 change | 29 March 2026 at 01:00 GMT → 02:00 BST (GOV.UK (official UK source)) |
| Autumn 2026 change | 25 October 2026 at 02:00 BST → 01:00 GMT (GOV.UK (official UK source); Timeanddate (London time zone)) |
| BST definition | One hour ahead of GMT, at UTC+1 (Timeanddate (BST reference)) |
| GMT vs UTC | GMT is a time zone; UTC is a time standard; both equal UTC+0 for clocks (Timeanddate (UTC reference)) |
| UK coverage | England, Scotland, Wales and Northern Ireland share one time zone (Timeanddate (time zone reference)) |
| Crown Dependencies | Guernsey, Jersey and the Isle of Man follow GMT/BST (Timeanddate (time zone reference)) |
| Overseas territories | Not automatically on BST; Gibraltar and the British Virgin Islands differ (Timeanddate (UK BST reference)) |
What is UTC to UK time?
The short version: when the UK is on GMT, UK time equals UTC; when it’s on BST, UK time is UTC+1. The labels matter more than the arithmetic.
What does UTC stand for?
- UTC stands for Coordinated Universal Time, the global standard that clocks around the world are set against (Timeanddate (UTC reference)).
- UTC is an atomic time standard, not a regional time zone.
What is the difference between UTC and GMT?
- GMT is technically a time zone — the local time at the Greenwich meridian — while UTC is a time standard (Timeanddate (UTC reference)).
- For practical clock comparisons, GMT and UTC line up at UTC+0 (Timeanddate (UTC reference)).
- The UK uses GMT as its winter clock label and BST as its summer clock label (GOV.UK (official UK source)).
How to convert UTC to UK time?
- During BST (last Sunday of March to last Sunday of October): add 1 hour to UTC. Noon UTC becomes 1:00 p.m. in the UK.
- During GMT (last Sunday of October to last Sunday of March): add 0 hours. Noon UTC stays noon in the UK.
- A converter set to a specific location such as London handles the seasonal switch automatically (Timeanddate (UK BST reference)).
The pattern: half the year the UK is UTC, the other half it’s UTC+1. The only variable is the season.
Using a fixed “GMT” label while summer is active puts your call an hour late, because the UK is UTC+1 from late March to late October (Timeanddate (UK BST reference)). A converter set to London tracks the change for you.
The implication: whether you add an hour or not depends entirely on the season, but a location-based converter eliminates the guesswork.
How many hours ahead is the UK time zone?
Never behind, and never more than one hour ahead. That’s the whole answer, with one seasonal twist.
Is the UK ahead or behind UTC?
- The UK is never behind UTC. During BST it is 1 hour ahead; during GMT it is exactly level with UTC (Timeanddate (time zone reference)).
What is the offset during BST?
- BST is UTC+1, one hour ahead of GMT and UTC (Timeanddate (BST reference)).
- BST runs from the last Sunday of March to the last Sunday of October (GOV.UK (official UK source)).
What is the offset during GMT?
- GMT is UTC+0, so UK clocks match UTC exactly during winter (Timeanddate (time zone reference)).
- GMT runs from the last Sunday of October to the last Sunday of March (GOV.UK (official UK source)).
The implication: “ahead of UTC” is the only direction the UK ever goes — the only question is whether it’s by one hour or zero.
What is the current time in the UK?
At the time of writing, the UK is on British Summer Time, so local time is UTC+1 (Timeanddate (time zone reference)). Here’s how to get the exact time and why a one-zone assumption can trip you up.
How to find the exact time in London
- A live reference such as Timeanddate shows London’s current clock time and updates every second (Timeanddate (London time zone)).
- Set your phone or calendar to “Europe/London” so appointments move with the clocks.
Time zones across the UK
- England observes GMT in winter and BST in summer (Timeanddate (England time zone)).
- Scotland, Wales and Northern Ireland follow the same GMT/BST system (Timeanddate (time zone reference)).
- The Crown Dependencies — Guernsey, Jersey and the Isle of Man — also switch between BST and GMT (Timeanddate (time zone reference)).
- British Overseas Territories do not automatically follow BST; Gibraltar and the British Virgin Islands, for example, sit outside the UK’s daylight-saving pattern (Timeanddate (UK BST reference)).
Daylight saving update
- BST began at 1:00 a.m. on 29 March 2026, when clocks moved from GMT to BST (GOV.UK (official UK source)).
- BST ends at 2:00 a.m. on 25 October 2026, when clocks move back to GMT (Timeanddate (London time zone)).
What this means: “UK time” is accurate for the four home nations and the Crown Dependencies, but not for every British territory. When in doubt, check the local clock of the exact place you’re calling.
Do we lose an hour when the clocks change in the UK?
Yes — in spring. In autumn, the UK gains it back. Here’s exactly how the two transitions work.
What happens during the Spring forward?
- On the last Sunday of March at 1:00 a.m. GMT, clocks jump forward one hour to 2:00 a.m. BST (GOV.UK (official UK source)).
- That day is only 23 hours long, so you lose one hour of it.
What happens during the Fall back?
- On the last Sunday of October at 2:00 a.m. BST, clocks fall back one hour to 1:00 a.m. GMT (GOV.UK (official UK source)).
- That night is 25 hours long, so you gain an hour of sleep.
Does the UK lose or gain an hour?
- Spring: lose an hour at 01:00 GMT → 02:00 BST.
- Autumn: gain an hour at 02:00 BST → 01:00 GMT.
- In 2026, the spring change was 29 March and the autumn change is 25 October (GOV.UK (official UK source)).
Spring costs you an hour; autumn gives it back. The 1968–1971 British Standard Time experiment shows the UK can skip the swap completely when it chooses to.
The pattern: losing an hour in spring is the price of lighter evenings; gaining it back in autumn is the compensation. Both dates are set by the last Sundays of March and October (GOV.UK (official UK source)).
What date do clocks go back in 2026 in the UK?
Sunday, 25 October 2026, at 2:00 a.m. local time. The UK moves from British Summer Time back to Greenwich Mean Time.
When does BST end in 2026?
- BST ends on 25 October 2026 — the last Sunday of October (GOV.UK (official UK source)).
- At that moment, London’s clocks go from 2:00 a.m. BST to 1:00 a.m. GMT (Timeanddate (London time zone)).
What time do the clocks change?
- The autumn change happens at 2:00 a.m. local time in the UK (GOV.UK (official UK source)).
- The spring change happens at 1:00 a.m. local time (GOV.UK (official UK source)).
Does the UK change clocks on the same day as the US?
- Not automatically. The UK sets its change dates by the last Sundays of March and October; other countries apply their own daylight-saving calendars (Timeanddate (UK BST reference)).
Why this matters: the weekend of 24–25 October 2026 is when the UK’s offset flips from UTC+1 to UTC+0. If you have calls or travel around then, check your scheduled times twice.
Why Britain’s clock has a strange history
Britain’s two-season clock is a political creation with a paper trail. A world war, a failed experiment, and EU harmonisation all left marks on the current system.
- — clocks go back at 02:00 → 01:00 GMT (GOV.UK (official UK source)).
The 1968–1971 experiment proved Britain could run on permanent BST for three years — and then it ended anyway. The country is still officially undecided about whether to try again.
The takeaway: what looks like a fixed, natural time zone is actually a policy choice with a legal history. The 2026 clock change is just the latest line in that record.
What’s confirmed, what’s still open
Confirmed facts
- UK uses GMT (UTC+0) in winter and BST (UTC+1) in summer (GOV.UK (official UK source)).
- Clock changes are set by the last Sunday of March and the last Sunday of October (GOV.UK (official UK source)).
- 2026 BST ends on 25 October at 2:00 a.m. (Timeanddate (London time zone)).
What’s unclear
- Whether the UK will permanently adopt BST or GMT after Brexit remains undecided as of 2026.
- 1880: GMT became the UK’s legal standard (historical record).
- 1916: The Summer Time Act introduced daylight saving to the UK.
- 1940–1945: Double British Summer Time was used during WWII.
- 1968–1971: Britain stayed on BST year-round in the British Standard Time experiment.
- 1996: EU harmonisation aligned the UK’s summer-time schedule with other European countries.
- A fixed “GMT” label in a converter can be off by one hour during summer; choosing “London” avoids the error (Timeanddate (UK BST reference)).
- “UK time” doesn’t extend to every British territory: Gibraltar and the British Virgin Islands don’t follow BST (Timeanddate (UK BST reference)).
The pattern: while the core schedule is law, the long-term future of the UK’s time zone is still open.
The official record on UK time
The UK’s clock-change rule is set in law: forward one hour at 1:00 a.m. on the last Sunday in March, back one hour at 2:00 a.m. on the last Sunday in October.
— GOV.UK (official UK source)
Greenwich Mean Time was adopted as the UK’s legal standard time in 1880.
— Royal Observatory Greenwich (historical authority on GMT)
The period when the UK is one hour ahead of GMT is officially called British Summer Time, and it runs from spring to autumn.
— GOV.UK (official UK source)
The record confirms that the UK’s time-zone rules are legally defined and have historical precedent.
The short version
Britain’s clock is a policy choice with a legal paper trail: GMT since 1880, daylight saving since 1916, one failed three-year experiment with permanent BST, and the next decision on the books for 25 October 2026 at 2:00 a.m. That date matters most if you’re scheduling calls, flights, or recurring meetings around the UK. For anyone coordinating across time zones, the choice is clear: use a converter set to London, or remember the formula — UTC+1 from late March to late October, UTC+0 the rest of the year.

Frequently asked questions
What is the difference between GMT and BST?
GMT (Greenwich Mean Time) is the UK’s winter clock at UTC+0; BST (British Summer Time) is the UK’s summer clock at UTC+1 (Timeanddate (BST reference)). The switch happens on the last Sunday of March and the last Sunday of October (GOV.UK (official UK source)).
Does the UK use 24-hour time or 12-hour time?
Both are common. Digital services, transport timetables, and broadcast schedules in the UK frequently use the 24-hour clock, while everyday conversation usually runs on 12-hour am/pm. There is no single official format — your phone and computer let you choose.
How do I convert UK time to my local time?
Find your time zone’s current offset from UTC, then apply the UK’s offset: UTC+1 during BST or UTC+0 during GMT. The simplest way is to set a world-clock app to “London” so it handles the seasonal change automatically (Timeanddate (UK BST reference)).
Is the UK ever on permanent BST?
Yes, historically. Between 1968 and 1971, the UK stayed on British Standard Time — effectively BST year-round — before returning to the seasonal GMT/BST cycle. As of 2026, no decision has been made on permanently adopting BST or GMT.
What time zone does the UK use in winter?
Greenwich Mean Time (GMT), which sits at UTC+0. It runs from the last Sunday of October to the last Sunday of March (GOV.UK (official UK source)).
Do all parts of the UK have the same time zone?
England, Scotland, Wales, and Northern Ireland share one time zone, and the Crown Dependencies (Guernsey, Jersey, Isle of Man) follow the same GMT/BST cycle (Timeanddate (time zone reference)). British Overseas Territories do not automatically observe BST.
The FAQs cover the most common points of confusion around UK time zones.
