Custom HouseHeathrow Terminal 5

£15.50 at any time for an adult single with contactless or Oyster. This fare is the same at every time of day.

Daily and weekly capping limits what you pay across all TfL services, so several journeys in a day often cost less than the singles added up.

Heathrow fares in full

Only 3 direct trains run Custom House to Heathrow Terminal 5 on a weekday - the service turns back before it gets there. Unless one happens to be next on the board, change at Heathrow Terminals 2 & 3: that takes about 65 minutes including a typical 8-minute wait, and costs the same - pay as you go charges for the journey, not the number of trains.

Direct trains are more frequent at weekends: 5 on a Saturday and 8 on a Sunday.

Direct trains are too rare to wait for. Take an Elizabeth line train to Heathrow Terminals 2 & 3 and change there for Heathrow Terminal 5. Allow about 5 minutes for the change; the typical wait is 8 minutes.

The 65 minutes above is measured across real connections in the timetable - each train matched to the next one you could actually catch, not two journey times added together.
