For most first-time visitors, the Elizabeth line is the best balance of speed, price and simplicity. It runs from every Heathrow terminal straight into central London, with stops such as Paddington, Bond Street, Tottenham Court Road and Liverpool Street, and you pay by tapping a contactless card. If speed to Paddington matters most, take the Heathrow Express. If cost matters most, take the Piccadilly line.
Heathrow Airport says the Elizabeth line serves Terminals 2, 3, 4 and 5. TfL says trains run about every 15 minutes from Terminals 2, 3 and 4, and about every 30 minutes from Terminal 5. The station for Terminals 2 and 3 sits between the two terminals, a few minutes' walk away. Terminal 4's station is below Arrivals, and Terminal 5's is in the basement of the terminal.
Many trains continue through central London without a change, calling at stations including Paddington, Bond Street, Tottenham Court Road, Farringdon and Liverpool Street. That can save you a transfer if your hotel is near one of those stops. TfL lists journey times excluding walking and changes, so allow a little extra time.
Heathrow Express runs non-stop to London Paddington every 15 minutes. Trains leave from the Heathrow Central station for Terminals 2 and 3, and from Terminal 5, which adds about 6 minutes. From Terminal 4, use the free transfer train to Terminals 2 and 3 first.
Fares on the Heathrow Express website:
Heathrow Express also accepts contactless and Oyster. Keep in mind that Paddington is on the western edge of central London, so many visitors still need a Tube or taxi from there.
The Piccadilly line is the Tube option. TfL lists it at Terminals 2, 3 and 5, with a journey of about 50 minutes to central London. Stops include Piccadilly Circus, Leicester Square and King's Cross St Pancras. It is slower and can be busy with luggage at rush hour, but it costs a fraction of the other two.
National Express coaches run between Heathrow and Victoria Coach Station, and every terminal has a taxi rank. These can make sense with heavy luggage or a late arrival, but they are not usually quicker than the train.
Fares and timetables change, and engineering works sometimes close lines at weekends. Check TfL or Heathrow Express before you fly.
