Daily caps are calculated over a 24-hour period, covering all the journeys started between 04:30 and 04:29 the next day. There are different caps for different types of transport and times of day.
Transport for London (TfL) can work out when you have reached a cap because every journey you make is logged and the system automatically keeps a running total of:
- All the zones you travel through
- What time you touch in on each journey (this determines both the fare and the cap)
- All fares paid in a single day
When the total cost of all your journeys reaches a certain amount, a cap is applied. Any journeys you make for the rest of the day in the same zones won’t be charged.
The cap you’re charged depends on the type of transport you’ve used. There are different caps for:
- All services (bus, Tube, tram, DLR, London Overground, TfL Rail and most* National Rail journeys in London)
- Bus & Tram (bus and tram journeys only)
Some journeys, no matter what route you take, are automatically charged to include Zone 1 and capping reflects this. You can find more information on Transport for London’s website.
