https://www.gov.uk/guidance/red-ambe...list-countries
When you arrive in England you need to follow the rules for the highest risk country or territory that you have been in or passed through in the previous 10 days. That can include transit stops.
A transit stop is a stop where passengers can get on or off the same part of the transport in which you are travelling. It can apply to ships, trains or flights. Your ticket should show if a stop is a transit stop.
The rules of a country or territory that you make a transit stop in could apply if:
- new passengers get on and are able to mix with you
- you or other passengers get off the transport you are on and mix with other people, then get on again
