BST to GMT time difference
GMT is 1 hour behind BST for most of 2026, and the same time as BST for about 155 days, because daylight saving time changes on different dates.
In 2026, UK Time switches to BST on March 29 and back to GMT on October 25. Greenwich Mean Time does not use daylight saving time.
