Which Heathrow terminals are connected?

Free London Underground services and shuttle trains (Elizabeth Line and Heathrow Express) are currently available for inter-terminal transfers between Heathrow Terminals 2&3 and Heathrow Terminal 5.



At London Heathrow in 2026, Terminals 2 and 3 are the only ones physically connected by a walking route. They share a "Central Terminal Area" and are linked by an underground pedestrian walkway; the walk takes about 10–12 minutes. Terminals 4 and 5 are located further away on different sides of the airfield and are not walkable from the others. However, they are all connected by free rail transfers. You can take the Elizabeth Line or the Heathrow Express for free between "Heathrow Central" (T2/T3) and Terminal 4 or Terminal 5. Just ensure you use a "Terminal Transfer" ticket or a contactless card (you won't be charged if you stay within the airport). In 2026, there is also a free shuttle bus that specifically serves Terminal 4. Always check your terminal before you arrive, as a "wrong terminal" mistake can add 20 minutes of travel time even with the efficient free train connections.
