You do not need a ticket, an Oyster card or any arithmetic, but you do need to tap the same card every time
Paying for London Transport: Contactless, Caps and Common Mistakes
Visitors arrive in London braced for a complicated ticketing system. There are zones. There are peak hours. There is a thing called an Oyster. People stand at the machines in the ticket hall doing sums.
The good news is that you can ignore almost all of it.
The One Rule
Take a contactless bank card, or a phone with Apple Pay or Google Pay. Touch it on the yellow reader when you enter the station and again when you leave. On buses, touch it once when you board. That is the whole system.
As one guide to the daily cap explains, there is no need for a Travelcard, a pre-loaded Oyster or any sums in advance. A contactless card or phone limits each day’s charges automatically, however often you ride.
The Cap
This is the clever part. The system adds up your journeys through the day. Once you reach a set amount, it stops charging. Everything after that is free until the early hours of the next morning.
The same guide gives the 2026 figure for Zones 1 and 2, where nearly every major sight is located, as 8.90 pounds, citing Transport for London’s official adult fares table. It is the same at peak and off-peak times. It notes that from 1 March 2026 single fares rose by around six percent, though the daily and weekly caps were frozen.
You will see other figures in older guides. Fares are reviewed each year, so check the Transport for London website for the current numbers. The principle does not change.
Buses
Buses have their own, lower cap, and a useful feature: after you pay for one bus, further bus journeys within an hour are free. If you travel only by bus, you will spend considerably less than on the Tube. It is slower, and you see the city.
The Mistake
Here is where people come unstuck. The cap is calculated per card. If you tap in with your phone in the morning and your plastic card in the afternoon, the system sees two different customers and caps neither.
A recent travel guide puts it well. Mixing your card and your phone on different days breaks the weekly cap, it warns, and calls this the mistake that quietly costs visitors the most.
The fix is simple. Pick one, your phone or one physical card, and use only that for your whole stay. A card and the same card loaded on a phone count as different.
Other Ways to Lose Money
A few more traps.
Forgetting to touch out. If you do not tap at the end of a Tube journey, the system does not know where you got off and charges a maximum fare.
Card clash. If you hold a wallet with several contactless cards against the reader, it may charge the wrong one. Take the card out.
Sharing. Each traveller needs their own card or device. You cannot tap two people through on one.
Foreign transaction fees. Your bank may charge for each use abroad. Check before you travel. Some cards have no such fees.
Paper tickets. Buying a single paper ticket from a machine costs a good deal more than the contactless fare for the same journey. There is rarely a reason to do it.
Do You Need an Oyster Card?
For most adult visitors, no. An Oyster card charges the same fares and caps as contactless but costs a fee to buy and has to be topped up. As the guide I quoted observes, most visitors never buy one at all.
There are exceptions. If your bank card is not contactless, or charges heavily for foreign transactions, an Oyster may be better. And if you are travelling with children aged 11 to 15, a discount can be set on an Oyster card at a station that halves their fares for a couple of weeks. Children under 11 travel free with a paying adult.
The Weekly Cap
If you are staying a week or more, there is also a weekly cap. It runs Monday to Sunday, which matters. A visit from Wednesday to Tuesday spans two capping weeks and may not reach the cap in either. You need do nothing to benefit. Just keep using the same card.
From the Airport
Contactless works on the Tube and the Elizabeth line from Heathrow, and on trains from Gatwick and London City. The express services from Heathrow and Gatwick are faster and much more expensive, and are not included in the daily cap. The ordinary services are perfectly good.
From Stansted and Luton, check before you travel whether contactless is accepted on your route, or buy a ticket in advance.
What Is Not Included
River boats accept contactless but do not count toward the cap. Nor do the airport express trains or the cable car. Taxis and ride-hailing are separate entirely.
A Few Kind Words About Walking
The Tube map is a diagram, not a map, and it lies about distance. Stations that look far apart are sometimes a five-minute stroll. Leicester Square to Covent Garden is a famous example: the train takes under a minute and the walk hardly longer. Before you descend, check whether you could simply go on foot. Central London is smaller than it looks.
In Short
One card or one phone. Touch in, touch out. Let the cap do the work. Check your bank’s foreign fees. And do not, whatever you do, stand at the ticket machine doing sums.
For the Journey
The Underground has inspired a great deal of affectionate mockery. The London Prat offers some in its English satirical news on the Tube and UK satirical news about tapping in and out. Bohiney Magazine covers the New York subway.
