Lagos is currently 1 hour ahead of London during Greenwich Mean Time (GMT, October–March) and on the same UTC+1 offset as London during British Summer Time (BST, March–October). This means there is no time difference between London and Lagos for roughly half the year.
London to Lagos — key time facts
- Lagos time zone: West Africa Time (WAT), IANA: Africa/Lagos, UTC+1 all year
- London time zone (winter): Greenwich Mean Time (GMT), UTC+0
- London time zone (summer): British Summer Time (BST), UTC+1
- Difference in winter (GMT): Lagos is 1 hour ahead of London
- Difference in summer (BST): Zero — both cities on UTC+1 simultaneously
- Lagos DST: None — WAT is permanent
- London DST: BST begins last Sunday of March, ends last Sunday of October
Note: Some timezone calculators show London–Lagos as 0 hours during winter, which is incorrect. During GMT (winter), London is UTC+0 and Lagos is UTC+1 — Lagos is 1 hour ahead. Only during BST (summer) does the gap become zero. If a tool tells you otherwise, it has a data error.
Business hours overlap
Lagos standard business hours: 8:00–17:00 WAT, Monday–Friday. London standard business hours: 9:00–17:30 GMT/BST, Monday–Friday.
In winter (London on GMT): London 9:00–17:00 GMT = Lagos 10:00–18:00 WAT. The full London working day falls within or near Lagos business hours. Best mutual window: 9:00–16:00 GMT (10:00–17:00 WAT).
In summer (London on BST): Both cities on UTC+1. London 9:00–17:00 BST = Lagos 9:00–17:00 WAT. A perfect overlap — every London business hour is simultaneously a Lagos business hour.

Who this matters to
London has the largest concentration of Nigerian diaspora outside Nigeria — over 200,000 people of Nigerian heritage in Greater London. The UK–Nigeria business corridor is one of the most active trade relationships in Africa. Nigerian-founded UK businesses, British companies with Lagos offices, and diaspora families calling home all share the same challenge: a time gap that disappears in summer and reappears in winter.
Knowing that the gap is zero from late March to late October eliminates a common scheduling error — teams that set a "standard" 9:00 AM GMT call with Lagos find it lands an hour later in Lagos during winter without anyone remembering to update the invite.
Unlike timeanddate.com, which shows this conversion with advertising, and devbox.tools, which has been observed to show incorrect London–Lagos data, TimezoneLink calculates the current offset live from the IANA database with no ads and no tracking.
