Getting from London to Heathrow
If you're starting in central London rather than at the airport, the same lines and fares apply in reverse. Join the Piccadilly line at any central London Tube station on that line (King's Cross St Pancras, Leicester Square, Green Park and Hammersmith are common interchanges) and ride it through to Heathrow Terminals 2&3, 4 or 5 for around £5.60. For the Elizabeth line, board westbound from Paddington, Bond Street, Tottenham Court Road, Farringdon or Liverpool Street for the flat £15.50 fare to any Heathrow terminal. The Heathrow Express only runs from Paddington, so it's the right choice if you're already near that station and want the 15-minute run out. Whichever way you're travelling, allow extra time to clear security if you're heading to the airport to catch a flight, since none of the journey times above include check-in or security.
Piccadilly line: cheapest, not fastest
The Piccadilly line is the lowest fare between London and Heathrow, from about £5.60 to £5.90 with contactless or Oyster. One quirk: it's charged at the peak rate at all times, with no off-peak discount, but it's still the cheapest way in either direction. The journey takes roughly 45 to 60 minutes, typically around 50 minutes, with a station between T2 and T3, plus stations at T4 and T5. Trains run from about 05:00 to 23:30, never more than 10 minutes apart, and the Night Tube runs all night on Fridays and Saturdays, useful for a very late or very early flight.
Elizabeth line: the value middle ground
The Elizabeth line serves all three Heathrow stations (T2/3, T4 and T5) and runs through Paddington, Bond Street, Tottenham Court Road, Farringdon and Liverpool Street. A single to or from Zone 1 is a flat £15.50, and the journey to Paddington takes about 30 to 40 minutes. For most travellers heading into the West End or the City, this is the best value-for-speed pick: roughly £10 cheaper than the Heathrow Express for a trip only about 20 minutes slower. It's also the direct line if Canary Wharf or the City is your start or end point rather than the West End.
Heathrow Express: fastest, priciest at the door
The Heathrow Express is the quickest way between the two, 15 minutes to or from Paddington from T2/T3 and 21 minutes from T5. A walk-up single is £26 standard class, but booking 30 or more days ahead brings it down to from £10, making early booking worthwhile if your travel date is fixed. Children aged 15 and under travel free with a fare-paying adult. Trains run every 15 minutes from early morning to late at night, and if you're connecting between T2/3 and T5, that segment of the Express is free.
Coach: cheaper than rail for some journeys
National Express coaches run between the Heathrow Central Bus Station (serving T2 and T3, with separate stops for T4 and T5) and London Victoria Coach Station, from £9.50 one-way with up to 77 services a day, taking about 45 to 90 minutes depending on traffic. It's a reasonable option if Victoria itself, or somewhere on the route, is more convenient than a rail terminus, though it's slower and less predictable than the Tube or Elizabeth line in heavy traffic.
Taxi: door to door, at a price
A metered black cab between Heathrow and central London typically runs £75 to £130 over about 18 miles and 45 to 75 minutes, on the standard TfL tariff (a £4.40 minimum fare, three time-of-day rate bands, plus a rank surcharge of about £1.60 and, when starting from the airport, the £7 terminal drop-off charge). A pre-booked minicab is usually cheaper and fixed in advance, commonly £45 to £75, with any drop-off charge already included.
A taxi is worth the premium for two or more people with luggage, since a pre-booked minicab can end up costing about the same per head as separate rail fares while collecting or dropping you at your exact address. It's also the simplest choice once the last Elizabeth line and Express trains have gone for the night; see our guide to getting into London late at night for that specific situation.
Which should you choose?
- Travelling solo or as a pair, no rush: the Piccadilly line. It's the cheapest option by a wide margin and runs all day.
- Want speed without paying Express prices: the Elizabeth line, especially if you're headed to or from the City or Canary Wharf rather than just the West End.
- Time-poor, or connecting to another train at Paddington: the Heathrow Express, booked in advance if you can, to bring the fare down from £26 to as little as £10.
- Group with luggage, or travelling very late: a pre-booked minicab, which fixes the price and removes any surge risk, and can pick you up from a home address rather than a station.
