Time Difference Between London and Singapore
Singapore is 8h ahead of London in standard time, and 7h ahead while London is on daylight saving time.
London clocks move forward on the last Sunday of March and back on the last Sunday of October. Singapore keeps the same clock all year. The figures above cover each part of the year. They do not come from the offset on the day the site was built. The live clocks use the current time.
Working Hours Overlap
For each hour of London's working day (9:00-18:00), here is the corresponding local time in Singapore. Rows highlighted green fall within standard working hours (9:00-18:00) in both cities. Each block is one part of the year, so the table does not change with the day this page was built.

Working Across London and Singapore
Seven hours makes this a morning-or-nothing corridor. Singapore's working day is finishing before London's has properly started: 5 PM in Singapore is 10 AM in London, and by 3 PM in London the Singapore side has been gone for hours. The usable band is 9 AM to noon London time, which is late afternoon and early evening in Singapore, and Singapore pays for it. Every hour London adds after lunch pushes the other end past 8 PM. Teams that run this route well stop trying to meet in the middle and hand over instead. Singapore closes its day with a written summary, London picks it up on arrival and replies while the Singapore evening is still young.
Singapore does not observe daylight saving at all, so London supplies the entire seasonal swing. The gap is eight hours while London is on standard time, seven hours from the last Sunday of March until the last Sunday of October, then eight again. In practical terms, a 9 AM London call sits at 4 PM in Singapore for most of the year and 5 PM during the winter months, which is the difference between catching someone before they leave and catching them after they have decided to. The predictability is worth something. Singapore's local hour holds the same offset from UTC every day of the year, so the only thing to check before booking is which side of the last Sunday of March or the last Sunday of October the date falls on.
About thirteen hours in the air, with seven or eight hours of clock change on top of it. Eastbound is the direction that costs you. Take a late departure from London and you arrive in Singapore in the early evening with a body that still thinks it is mid-morning; the nap that feels entirely reasonable at that point is what ruins the next day. Going west, London's first day simply feels long. There is no date line on this route, so the calendar behaves normally, but an evening departure from London still lands the following day in Singapore, and people booking onward connections for the departure date get caught by that more often than they should.
