How to Change the Clocks: Phones, Cars, Ovens and More

Smartphones, tablets, laptops, smart TVs and most smart speakers pull the time from the network and apply the correct UK rules. Check that the time zone is set to London or Europe/London, not a fixed offset such as GMT+0.

Radio-controlled wall clocks and watches pick up the national MSF time signal and change on their own, usually within a day.

Ovens, microwaves, central-heating timers, some car dashboards, analogue wall clocks and many fitness trackers need manual changes. Cars with satellite navigation often update automatically, while older models do not.

Set heating and lighting timers last, then walk through the house once to catch any clock you forgot.

Automation routines that use sunrise or sunset adjust on their own, but those set to a fixed clock time shift against daylight. After the autumn change, check any porch lights or blinds that rely on a set time.
