Because London is on UK time, there is no need to plan around a time difference. Any time that suits you in the UK will match London exactly.
Good to know
- London and the rest of the UK move their clocks together, so the switch between GMT and BST never creates a gap between London and elsewhere in the country.
- When people say "UK time", they mean the time in London - it is the country's official reference point.
Frequently asked questions
What is the time difference between the UK and London?
There is none. London is the UK, so its clock is always the same as UK time, whether that is GMT in winter or BST in summer.
Is London ahead of or behind the UK?
Neither - London is not a separate time zone from the UK. It keeps identical time to the rest of the country all year round.
