Lisbon and London share the same timezone year-round. When it's 12:00 PM in London, it's also 12:00 PM in Lisbon. Both cities observe DST on the same schedule.
Portugal uses WET/WEST (same as UK's GMT/BST), making it the only continental European country to share the UK's timezone.
Any time works! Business hours are identical. 9:00 AM - 5:00 PM London is exactly 9:00 AM - 5:00 PM Lisbon. Perfect overlap.
Lisbon is a growing tech hub and popular destination for British tourists and expats. The 2.5-hour flight makes it one of the most convenient European destinations from London.
