How a cap works
We work out when you've reached a cap because we log every journey you make and keep track of:
You must touch in at start and touch out at the end of every journey, using the same contactless card, device or Oyster card. If you don't you may be charged a maximum fare.
If you use contactless, always use the same card or device. If you don't, we can't cap your fares. For example, if you pay with a mobile device on Monday and a contactless card on Tuesday, these fares won't count towards a weekly cap.
Daily cap
A daily cap is calculated over 24 hours for pay as you go journeys that start at 04:30 and end on 04:29 the next day.
Weekly cap
A weekly cap limits how much you pay for all your journeys in a fixed Monday to Sunday period. It works using adult rate pay as you go on contactless (card or device) or Oyster.
If you do a single week of travel starting later in the week, for example from Thursday to Wednesday, there are not enough days up to Sunday to reach a weekly cap. So you may find it better value to buy a 7 Day Travelcard.
But generally, pay as you go with weekly capping does not exceed the price of a 7 Day Travelcard and it is likely to prove better value. With pay as you go, you only pay for days on which you travel, which in some weeks might turn out to be less than you intend. With a 7 Day Travelcard you always pay for the equivalent of five days' travel.
