The London to Singapore Time Difference
London operates on Greenwich Mean Time (GMT) (UTC+0) during winter and British Summer Time (BST) (UTC+1) from the last Sunday in March to the last Sunday in October. Singapore does not observe daylight saving time and remains on Singapore Time (SGT), which is UTC+8 all year. Therefore, the time difference is:
- During BST (summer): Singapore is 7 hours ahead of London.
- During GMT (winter): Singapore is 8 hours ahead of London.
For example, when it is 12:00 noon in London during BST, it is 19:00 (7:00 PM) in Singapore. During GMT, 12:00 noon in London corresponds to 20:00 (8:00 PM) in Singapore.

Best Times to Schedule Calls
Given the 7-8 hour gap, the best overlap for business calls is typically late morning in London and late afternoon in Singapore. For example, 09:00-12:00 London time (BST) corresponds to 16:00-19:00 Singapore time. During GMT, the overlap shifts slightly earlier: 09:00-12:00 London time is 17:00-20:00 Singapore time. Avoid scheduling early morning London calls as it will be late evening in Singapore. For personal calls, evenings in London (after 18:00) are early morning the next day in Singapore, which may be less convenient.
