when do clocks change uk

In the UK in 2025, the clocks will go forward by one hour (start of British Summer Time) at 1:00 am on Sunday, 30 March. Later in the year, the clocks will go back by one hour (end of British Summer Time) at 2:00 am on Sunday, 26 October. This means the official time shifts forward in late March for lighter evenings, and then shifts back in late October to standard time with an extra hour of sleep.
