BST to UTC: BST is 1 hour ahead of UTC
UK Time is 1 hour ahead of Coordinated Universal Time right now. It is 8:37 pm BST in UK and 7:37 pm UTC in UTC.
Convert a specific time from BST to UTC
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between BST and UTC?
Coordinated Universal Time is 1 hour behind UK Time. To go from BST to UTC you subtract 1 hour. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from no difference to 1 hour, because UK moves its clocks and UTC does not. This page recomputes it rather than assuming.
BST to UTC conversion table
Every hour of Wednesday, September 23, 2026 in UK, with the matching reading in UTC. 1 of the 24 hours land on a different calendar date in UTC, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between BST and UTC?
7 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 10:00 am BST to 5:00 pm BST. In UTC that window reads 9:00 am to 4:00 pm. Outside it, one side is either not yet at their desk or already gone.
| BST | UTC | Working hours | Note |
|---|---|---|---|
| 10:00 am | 9:00 am | both sides | mid morning in UK, mid morning in UTC |
| 11:00 am | 10:00 am | both sides | mid morning in UK, mid morning in UTC |
| 12:00 pm | 11:00 am | both sides | noon in UK, mid morning in UTC |
| 1:00 pm | 12:00 pm | both sides | afternoon in UK, noon in UTC |
| 2:00 pm | 1:00 pm | both sides | afternoon in UK, afternoon in UTC |
| 3:00 pm | 2:00 pm | both sides | afternoon in UK, afternoon in UTC |
| 4:00 pm | 3:00 pm | both sides | afternoon in UK, afternoon in UTC |
Does daylight saving change BST to UTC?
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is no difference and for the rest it is 1 hour. The table above is built for today, not for an average day.
Is BST ahead of or behind UTC?
BST is ahead of UTC by 1 hour: when it is 12:00 pm in UK, it is 11:00 am in UTC. One wrinkle worth knowing: GMT and BST are two names for the same zone, not two zones. UK Time reads GMT in winter and BST in summer. When somebody types "bst to utc" they nearly always mean the zone rather than the literal winter offset, so this page resolves BST to Europe/London and UTC to Etc/UTC and applies whichever offset is genuinely in force on the day.
UK Time covers London, Cardiff, Edinburgh and Dublin. Coordinated Universal Time covers the reference all other zones are measured against. The identifiers behind them are Europe/London and Etc/UTC, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
