Every year our clocks go forward by an hour in March and fall back an hour in October as British Summer Time (BST) finishes and Daylight Saving Time (DST) starts. The majority of our controls have DST settings built in and will automatically change the time on the 28th March, meaning you wont have to do anything. However, click on your control below to check if you need to change the time, as well as instructions on how to do it.
