UTC to BST: UTC is 1 hour behind BST
Coordinated Universal Time is 1 hour behind UK Time right now. It is 7:34 pm UTC in UTC and 8:34 pm BST in UK.
Convert a specific time from UTC to BST
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 UTC and BST?
UK Time is 1 hour ahead of Coordinated Universal Time. To go from UTC to BST you add 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.
UTC to BST conversion table
Every hour of Wednesday, September 23, 2026 in UTC, with the matching reading in UK. 1 of the 24 hours land on a different calendar date in UK, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between UTC and BST?
7 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 9:00 am UTC to 4:00 pm UTC. In UK that window reads 10:00 am to 5:00 pm. Outside it, one side is either not yet at their desk or already gone.
| UTC | BST | Working hours | Note |
|---|---|---|---|
| 9:00 am | 10:00 am | both sides | mid morning in UTC, mid morning in UK |
| 10:00 am | 11:00 am | both sides | mid morning in UTC, mid morning in UK |
| 11:00 am | 12:00 pm | both sides | mid morning in UTC, noon in UK |
| 12:00 pm | 1:00 pm | both sides | noon in UTC, afternoon in UK |
| 1:00 pm | 2:00 pm | both sides | afternoon in UTC, afternoon in UK |
| 2:00 pm | 3:00 pm | both sides | afternoon in UTC, afternoon in UK |
| 3:00 pm | 4:00 pm | both sides | afternoon in UTC, afternoon in UK |
Does daylight saving change UTC to BST?
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
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.
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 UTC ahead of or behind BST?
UTC is behind BST by 1 hour: when it is 12:00 pm in UTC, it is 1:00 pm in UK. 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 "utc to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves UTC to Etc/UTC and BST to Europe/London and applies whichever offset is genuinely in force on the day.
Coordinated Universal Time covers the reference all other zones are measured against. UK Time covers London, Cardiff, Edinburgh and Dublin. The identifiers behind them are Etc/UTC and Europe/London, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
