Singapore operates on Singapore Standard Time (SGT), which is UTC+8. Singapore does not observe Daylight Saving Time.

The UK shifts between GMT (UTC+0) in winter and BST (UTC+1) in summer.

Quick Conversions: UK to Singapore

Best Overlap for UK–Singapore Calls

The workable overlap between UK and Singapore business hours is limited. In UK winter, UK 9am–1pm overlaps with Singapore 5pm–9pm (end of Singapore day). In UK summer, UK 9am–1pm overlaps with Singapore 4pm–8pm.

For regular cross-timezone meetings, early UK morning or late Singapore afternoon tends to be the most sustainable overlap window.

The DST Trap: Why UK–Singapore Calls Go Wrong

The most common scheduling mistake on this corridor happens in late March and late October, when the UK changes its clocks.

If you have a standing call scheduled at "9am London time," it will shift by one hour relative to Singapore twice a year. Many recurring calendar invites don't automatically update.

Singapore-based participants see the same UTC+8 time they always did; the London meeting has moved by an hour on their local clock. This catches people out every year.

About Singapore Standard Time

Singapore has used UTC+8 since 1982. Before that, Singapore used UTC+7:30. The current single-offset system, with no DST, makes Singapore one of the most predictable timezones to work with internationally — the challenge is always with the countries at the other end of the call.
