The Tube, buses and contactless: how to pay for London transit in 2026

Tap the same contactless card or phone every time, and Transport for London (TfL) caps what you pay each day and each week, so you'll rarely need to think about tickets at all.

The short version

• Your US card probably works. Contactless credit and debit cards, and phones with Apple Pay or Google Pay, work on the Tube, buses, the Elizabeth line and London Overground. Check your bank's foreign transaction fees.
• Buses are £1.85 (about USD 2.48) with unlimited bus and tram rides within an hour of your first tap, the Hopper fare. The daily bus cap is £5.55 (about USD 7.44) [7].
• Tube fares went up on March 1, 2026, with a Zone 1 peak single rising from £2.90 to £3.10 (about USD 4.15) [2]. Pay as you go caps and Travelcards were frozen [2][3].
• The Zones 1–2 daily cap is £8.90 (about USD 11.90) and the Monday-to-Sunday cap is £44.70 (about USD 60) [4].
• Got a 16-25 or 26-30 Railcard? Add it to an Oyster card for a third off off-peak pay as you go fares [5].

Contactless or Oyster?

For most Americans, contactless wins. You already have the card, there's nothing to top up, and the caps work automatically.

A few things Americans learn the hard way:

• Watch your foreign transaction fees. Every tap posts in pounds. A US card with no foreign transaction fee is a no-brainer; a 3% fee on every bus ride adds up. Once you have a UK bank account, switch to your UK debit card.
• Avoid "card clash." If you hold your whole wallet to the yellow reader, it may charge the wrong card, or both. Tap one card only.
• Card and phone count as different cards. The plastic card and the same card in your phone wallet have different numbers, so mixing them breaks your cap. Pick one and stick with it.
• Touch in and touch out on the Tube, Elizabeth line and Overground. Forget to tap out and you can be charged a maximum fare. On buses, you only tap when you board.

How zones and fares work

London's rail network is split into zones, from Zone 1 in the middle (the West End, the City, Westminster) out to Zone 6 and beyond, which includes Heathrow. Your fare depends on which zones you pass through and whether you travel at peak time.

Peak hours are Monday to Friday, roughly 6:30 to 9:30 a.m. and 4 to 7 p.m., not counting public holidays. Everything else is off-peak and cheaper.

The 2026 fare round raised overall TfL fares by an average of 3.2%, with pay as you go Tube and rail singles up by about 6% on average, but caps, Travelcards and all bus fares stayed frozen [2]. TfL said singles in Zones 1–6 rose by no more than 20p, many by just 10p [3].

Caps rise as you add zones. If you live in Zone 3 and work in Zone 1, check TfL's single fare finder for your exact cap.

Daily vs weekly caps

Here's the trick: TfL caps your spending each day, and also over each Monday-to-Sunday week. If you commute five days a week, you'll often hit the weekly cap by Thursday or Friday and ride free for the rest of the week. You don't need to buy a weekly ticket. Just tap the same card every time.

The weekly cap resets on Monday, not seven days from your first trip. If you start a new job on a Wednesday, you won't reach the weekly cap that first week. A monthly or annual Travelcard on Oyster only makes sense if you travel nearly every day; do the math first.

Buses

London buses haven't taken cash for years, so you pay with contactless or Oyster [1]. The Hopper fare is the sweet spot: tap the same card and you get unlimited bus and tram rides within an hour of your first tap for £1.85 [7]. Heads-up: bus and tram fares were frozen at £1.75 until the Mayor's July 2026 decision raised them to £1.85 from November 1, 2026, with the daily bus and tram cap going from £5.25 to £5.55 [7].

Railcards: the discount nobody tells you about

Railcards are discount cards for National Rail, and some of them also cut your London fares. TfL lets you add these to an Oyster card for a third off off-peak pay as you go fares [5]:

• 16-25 Railcard
• 26-30 Railcard
• Senior Railcard (60 and over)
• HM Forces Railcard
• Disabled Persons Railcard
• Veterans Railcard

The Network Railcard, Family & Friends Railcard and Two Together Railcard can't be added to Oyster, though they still save you money on National Rail trips [5].

To set it up:

1. Buy the Railcard for National Rail travel, usually a digital Railcard in an app or a physical card.
2. Get an Oyster card and register it online so you can get refunds and replacements [5].
3. Ask staff at a Tube, London Overground or some Elizabeth line stations, or at an Oyster Ticket Stop, to add the discount. Bring the Railcard [5].
4. Re-add the discount each time you renew the Railcard [5].

If you're 26 to 30, this is easy money, a little like finding out your Costco membership covers gas too.

Night Tube, night buses and the Elizabeth line

Night Tube

On Friday and Saturday nights, the Central, Jubilee, Northern, Piccadilly and Victoria lines run through the night on parts of their routes, and TfL publishes a separate Night Tube and London Overground map [6]. The rest of the week, the Tube stops a bit after midnight, and London's night buses (the routes starting with N) take over. They cost the same £1.85 as day buses [7].

The Elizabeth line

The purple Elizabeth line runs east to west under central London, from Reading and Heathrow out to Shenfield and Abbey Wood. It's fast, air-conditioned and the closest thing London has to a new US subway line. You tap in and out just as on the Tube, and it counts toward your caps.

Getting to Heathrow

For your Thanksgiving flight home, the Elizabeth line is usually the sweet spot between price and time. If you're hauling two suitcases at 6 a.m., a cab or rideshare might win.

The US side

Your US credit card rewards may still pay off on TfL taps, but keep your US card active only if it has no foreign transaction fees. Once you're settled, a UK debit card for transit avoids currency conversion entirely. And if you're keeping a US card for the points, keep an eye on your US credit score from abroad.
