<P> British Summer Time was first established by the Summer Time Act 1916 , after a campaign by builder William Willett . His original proposal was to move the clocks forward by 80 minutes , in 20 - minute weekly steps on Sundays in April and by the reverse procedure in September . In 1916 , BST began on 21 May and ended on 1 October . Willett never got to see his idea implemented as he died in early 1915 . </P>
