British Summer Time ends officially on Sunday. This means that from 2am on Sunday morning it's time to set your clocks and watches back by one hour. The result will be that darkness arrives sooner in the evenings.
Although there have been debates over the years about bringing the UK into line with Central European Time, the Department for Business, Innovation and Skills says: "There are no current plans to change the UK's time zone".
Clocks will go forward again on 31 March next year.
