If you've moved abroad and kept a UK employer, or you're managing a team split across time zones, the difference between a workable arrangement and a punishing one is usually three or four hours of overlap. This guide maps the UK's overlap windows with the major remote-work hubs in 2026 and the practical patterns expat workers settle into.
The UK uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October. Most other countries change clocks on different dates, briefly making overlap windows longer or shorter.
Windows you negotiate against your manager's calendar should always be expressed in UK clock time — BST or GMT — not 'UK time'. Half the world's calendar invitations get this wrong twice a year.
Central European Time (Spain, France, Germany, Italy, Portugal-mainland excepted): UTC+1 winter, UTC+2 summer. Always 1 hour ahead of the UK. A 9am-5pm UK day = 10am-6pm CET. Overlap is essentially full — the easiest scenario for working with a UK team.
Portugal mainland: same as UK (UTC+0 / UTC+1). Greece, Cyprus, Romania, Bulgaria, Finland: UTC+2 / UTC+3. Still very workable. UK 9am-5pm = 11am-7pm in Athens.
UAE (Dubai, Abu Dhabi): UTC+4 year-round (no DST). UK 9am-5pm = 1pm-9pm Dubai in winter, 12pm-8pm in summer. The afternoon-and-evening overlap suits Dubai-based account managers serving UK clients.
South Africa (Johannesburg, Cape Town): UTC+2 year-round. Overlap of 6+ hours with UK working day — one of the best long-distance fits.
Singapore, Hong Kong, Malaysia, Philippines: UTC+8. UK 9am = 4pm-5pm in Singapore. 3-4 hours of overlap (UK morning = Singapore late afternoon).
India (Mumbai, Bangalore): UTC+5:30. Overlap of 4-5 hours including UK morning. Australia (Sydney): UTC+10/+11. Overlap shrinks to 1-2 hours — UK morning meets Sydney evening, or vice versa.
US East Coast (New York, Boston, Toronto): UTC-5/-4. Overlap of 3-4 hours from UK afternoon. Workable for most schedules.
US West Coast (San Francisco, Los Angeles, Vancouver): UTC-8/-7. Overlap shrinks to 1-2 hours — UK 5pm-7pm meets US 9am-11am. Most UK-LA arrangements settle on a single daily overlap window with async work the rest of the time.
South America: Brazil (UTC-3) gives 4 hours of overlap; Mexico City (UTC-6) gives 2-3 hours. Argentina, Chile and Peru are similar to US East Coast.
Most teams find 2-3 hours of daily overlap workable for collaborative roles, 4+ hours for management. Below 2 hours, schedule shifts become punishing for one side.
Calendar invites set in your local time zone with the time-zone field set correctly will auto-adjust on both sides. The recurring-meeting trap is starting a series in summer and forgetting it shifts when one country changes clocks.
Yes — many West-Coast/UK arrangements use a 6am-10am + 2pm-6pm pattern on the UK side, leaving the middle of the day for deep work and family time.
