When Does The Clock Change 2025. The clocks go back at 2am sunday 27th october 2025, marking the end of daylight saving time (dst) or british summer time (bst), and the move to greenwich mean time (gmt). The end to daylight saving time means our clocks fall back early sunday, nov.

Will we gain or lose an hour when dst ends? When do the clocks change in 2025?
