From the last Sunday in March (when London moves forward), Lagos and London show the same clock time.

Next clock change for this pair, as of when this page was built (2026-10-20): London falls back on Sun 25 October 2026.

Everything on this page also holds if you swap London for Birmingham, Dublin, Glasgow, Manchester or Lisbon, or Lagos for Kinshasa, Luanda, Abuja, Algiers or Brazzaville — those cities follow exactly the same clock all year.

Common mistakes with London and Lagos

  • Forgetting that the gap changes even though Lagos never touches its clocks: London does, so a meeting fixed in Lagos time moves by an hour for people in London.
  • Writing “GMT” all year for London. In summer the zone is British Summer Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
