The UK uses GMT (Greenwich Mean Time) and BST (British Summer Time) instead of UTC mainly due to historical and practical reasons. GMT has been the benchmark for timekeeping since the 19th century. BST is used during daylight saving time for better utilization of daylight, whereas UTC does not account for this seasonal change. This dual-time system helps the UK optimize energy use and daylight.
