Getting to central London from London Heathrow Airport (LHR)

Heathrow Airport is about 23 km west of central London. It has four active terminals (2, 3, 4 and 5) that are not all within walking distance, so check which one your airline uses before planning your journey.

  • Elizabeth line is the best option for most travellers. Modern trains with luggage space run to Paddington in about 28 minutes and continue through to the City, Liverpool Street and Canary Wharf without changing. About 6 trains per hour. Works with Oyster or any contactless bank card.
  • Piccadilly line (Underground) is the cheapest rail option, taking 50 to 60 minutes to central London. Serves all terminals including Terminal 4. Runs 24 hours on Friday and Saturday nights.
  • Heathrow Express is a non-stop premium train to Paddington in 15 minutes. The most expensive option, but advance online fares are cheaper than buying at the station.
  • National Express coaches run from the Central Bus Station (between Terminals 2 and 3) to Victoria Coach Station in about 60 to 80 minutes.

Oyster cards and contactless bank cards work on the Elizabeth line and Piccadilly line with automatic daily fare capping. Terminal 4 is on a spur, so check train frequencies for your terminal before heading to the platform.
