Clock changes in London
Since 1970, London has gone through 3 distinct time-keeping periods, observing daylight saving time in 55 of 57 years. The current pattern, in place since 1972, is UTC +00:00 with UTC +01:00 in daylight saving time. Clocks currently go forward on the last Sunday in March and back on the last Sunday in October, a rule in place since 1996.
| Date | Change | Local clock | New offset |
|---|---|---|---|
| Sunday, 29 March 2026 | Forward 1 hour | 01:00 → 02:00 | UTC +01:00 |
| Sunday, 25 October 2026 | Back 1 hour | 02:00 → 01:00 | UTC +00:00 |
| Sunday, 28 March 2027 | Forward 1 hour | 01:00 → 02:00 | UTC +01:00 |
| Sunday, 31 October 2027 | Back 1 hour | 02:00 → 01:00 | UTC +00:00 |
When clocks go forward, sunrise and sunset both happen an hour later by the clock — darker mornings, lighter evenings — and the night of the change is an hour shorter. When they go back, the reverse applies.
