London to Singapore: time difference and meeting times
Everything you need to schedule between London and Singapore — the current offset, both cities' daylight saving dates, and the hour-by-hour overlap of their working days.
2 hours of full overlap. Both cities are inside normal working hours (09:00–17:59 local) at 08:00–10:00 UTC. Any hour in that range works for both sides without anyone starting early or finishing late.

Daylight saving
London next moves its clocks back on 25 October 2026, to UTC+0. Singapore does not observe daylight saving — this offset is fixed all year.
Only one side changes its clocks
London observes daylight saving and Singapore does not. The difference between these two cities is therefore not constant — it changes twice a year, entirely because of the London side. A recurring meeting fixed to local time in Singapore will appear to move by an hour in London, and vice versa.
Scheduling across this corridor
Southeast Asia sits far enough ahead of Europe that the overlap falls at the very start of the European day and the very end of the Asian one. Morning in London or Berlin is early evening in Singapore or Jakarta, which is the only realistic meeting window. Neither Singapore nor Indonesia observes daylight saving, so the whole seasonal swing comes from the European side and the gap narrows by an hour when Europe is on summer time.
About London
London is the practical reference point for global scheduling, sitting at UTC in winter and an hour ahead of it in summer. That is precisely why UTC and London time are not the same thing for most of the year, and why "GMT" used loosely between April and October is usually wrong. British Summer Time runs from the last Sunday in March to the last Sunday in October, on the EU schedule rather than the American one.
About Singapore
Singapore holds a fixed offset year-round with no daylight saving, eight hours ahead of UTC — a notable detail given its longitude, since the country sits further east on the clock than the sun would suggest. Its position makes it the standard meeting point for Asian regional business, with a working day that reaches both the European morning and the Australian afternoon.
