In the UK, the clocks change twice a year: they go forward 1 hour on the last Sunday in March and go back 1 hour on the last Sunday in October.

Quick Scoop

  • In March, at 1:00am, the time jumps to 2:00am – this is the start of British Summer Time (BST).
  • In October, at 2:00am, the time goes back to 1:00am – this returns the UK to Greenwich Mean Time (GMT).
  • A handy way to remember it is: “spring forward, fall back”.

Upcoming UK clock change dates

  • In 2026, the clocks go forward at 1:00am on Sunday 29 March.
  • In 2026, the clocks go back at 2:00am on Sunday 25 October.

Why the clocks change

  • The UK uses daylight saving time to give more evening daylight in spring and summer, called British Summer Time.
  • In winter, switching back to GMT aligns daylight more closely with typical working and school hours.
