Set a call for 14:00 in Brussels and your London colleague joins at 13:00. Every time. The cities switch their clocks on the same Sundays, so the gap never budges.

Why London Is Always 1 Hour Behind Brussels

London runs on GMT (UTC+0) in winter and BST (UTC+1) in summer. Brussels uses CET (UTC+1) in winter and CEST (UTC+2) in summer.

Both cities observe daylight saving. Both change on the same dates: the last Sunday in March and the last Sunday in October. Because the UK and Belgium shift together, the one-hour gap is permanent.

Brussels winter (CET, UTC+1) means London winter (GMT, UTC+0). Brussels summer (CEST, UTC+2) means London summer (BST, UTC+1). Brussels is always 1 hour ahead.

No overlap. No exception. Not even during the transition weekends.

GMT vs BST: How UK Time Relates to CET and CEST

The UK switches between GMT and BST. Brussels switches between CET and CEST. The labels change. The arithmetic does not.

Period	Brussels offset	London offset	Difference
Late October to late March	UTC+1 (CET)	UTC+0 (GMT)	Brussels +1 h
Late March to late October	UTC+2 (CEST)	UTC+1 (BST)	Brussels +1 h

For 2026 and 2027 the transition dates are identical:

Spring 2026: 29 March. Brussels goes from CET to CEST; London goes from GMT to BST.
Autumn 2026: 25 October. Both revert.
Spring 2027: 28 March.
Autumn 2027: 31 October.

If Brussels is on CEST, London is on BST. If Brussels is on CET, London is on GMT. The gap holds.

What Is the Best Time to Call London From Brussels?

The entire business day overlaps. That is the main advantage of this route.

Standard office hours in Brussels run 09:00 to 17:30. In London that is 08:00 to 16:30. No part of the working day is cut off.

Schedule a 10:00 meeting in Brussels and London joins at 09:00. London wants a 14:00 call? Brussels takes it at 15:00. Brussels lunch runs 12:00 to 13:30, London lunch 11:00 to 12:30.

The one-hour offset is negligible for daily coordination. It matters more for flights, deadlines and live events.

If you need to call outside business hours, see the best time to call Brussels guide for other time zones. London is the easiest.

The flight from Brussels Airport (BRU) to London Heathrow or St Pancras via Eurostar takes about one hour twenty minutes. The time difference is less than the flight time.
