Airside transit
Airside transit is when you do not pass through UK border control. You remain ‘airside’ before you leave the UK on your connecting journey.
If you transit airside, you do not need to take a COVID-19 test before you travel to England if you:
qualify as fully vaccinated for travel to England
have not been in a red list country or territory in the 10 days before you arrive in England
