Transit & visa requirements
- Most passengers connecting airside between international flights do not pass UK immigration — but some nationalities require a Direct Airside Transit Visa (DATV).
- If your itinerary requires changing terminals landside or collecting bags, you will pass through UK border control and need a visa if your nationality requires one.
Things to do during a layover at LHR
Stay airside at London Heathrow Airport. Clear security to your connection early, then find a lounge or quiet seating area near your departure gate.
Enough time to relax in a lounge, eat a proper meal and explore the terminal’s shops and amenities without rushing your connection.
With a long layover you may have time to leave the airport and see London, provided your nationality and routing allow you to clear immigration. Confirm transit visa rules first, and leave a generous buffer to return.
