At London Heathrow’s Terminal 5, the Arrivals hall is located on the Ground Floor (Level 0). This applies to both international and domestic flights. After passengers clear immigration and collect their luggage in the baggage reclaim area, they emerge into the public arrivals concourse on the ground level. This floor houses the meeting points, currency exchange kiosks, and various cafes like Costa or Marks & Spencer Food. For onward travel, the taxi ranks and local bus stops are located immediately outside the ground-floor exits. If you are looking for the Heathrow Express or the Elizabeth Line, you need to head down to the basement levels, while the Underground (Piccadilly Line) is accessible via a short walk. Conversely, if you are looking for Departures and Check-in, you must head up to Level 3. In 2026, digital signage throughout the terminal is highly efficient, but remembering that "Arrivals equals Ground Floor" is the simplest way to navigate this massive building.
