What happens if I forget to tap off the bus?

On a tap-on, tap-off network, a missed tap-off usually costs you more. First Bus, for example, says you will be charged the single fare to the end of the route, and that if you are overcharged as a result you can request a refund through its online portal. In London you only touch in on buses, so there is no tap-off to miss. Check your own operator's rule before travelling.

Can I switch between my phone and my card on the same day?

You can, but it can cost you the fare cap. TfL says capping requires the same card or device for all journeys in the day and week, and First Bus says each card or device acts as a separate ticket with separate caps. A phone and the card loaded into it count as two payment methods, so pick one in the morning and use it for every journey that day.

What do I show a ticket inspector if I paid by contactless?

Show the exact card or device you tapped with. First Bus says your card acts as your ticket, and TfL's conditions say you may be asked to touch it on the inspector's portable reader. In London, if you did not touch in or your phone's battery has died so it cannot be read, you may face a maximum fare, a revenue inspection charge, a penalty fare or prosecution.

Why was my contactless card declined on the bus?

One common reason is an unpaid earlier fare. Bus payments are often taken later in the day, and if that payment fails the card can be blocked for travel. TfL says it retries up to three times within 30 days and you cannot travel on that card until it is paid; First Bus says its card stays declined until the outstanding fare is settled. Carry a second card as a backup.

Can children or bus pass holders pay by contactless?

Contactless pay as you go is often set up for adult fares only. First Bus says its tap on, tap off scheme is not available for child, student or group fares, so buy the right ticket from the driver or the operator's app instead. If you hold an older or disabled person's bus pass, show the pass rather than tapping a bank card, which would charge you a fare.

Contactless Bus Payment in the UK: What to Check First

The Coachway · Updated 2026-10-11 · 8 min read

The verdictMost UK buses let you pay by tapping a contactless bank card, phone or watch on the ticket machine reader, but the rules are set locally. In London you tap once as you board; many other networks ask you to tap off too, or charge the fare to the end of the route. Daily and weekly caps only work if you use the same card or device every time, and accepted cards vary by operator, so check the operator's own page first.

How does contactless bus payment work in the UK?

On most UK buses you can now pay by tapping a contactless bank card, phone or watch on the ticket machine reader instead of buying a paper ticket. The details are local, though: some networks want one tap as you board, others want a second tap as you get off, accepted cards differ by operator, and daily or weekly caps only work if you use the same card or device every time. Check the operator's own page for your route before you rely on it.

Contactless beats counting out coins, but "tap and go" hides rules that cost money when missed. The worked examples below are London (Transport for London, or TfL) and First Bus, because both publish their rules plainly. Fares were checked in October 2026 and will change.

Which cards and devices will the bus actually accept?

A card that works in a shop may not work on a bus. Each operator sets its own list.

First Bus says it accepts Visa and Mastercard cards showing the contactless symbol, plus Apple Pay and Google Pay, but states on its contactless help page that it does not accept American Express or Maestro.
TfL lists a wider range of mobile wallets on its contactless pay as you go page, including Apple Pay, Google Pay, Samsung Pay, Fitbit Pay and Garmin Pay.

If you are visiting from abroad, both say many contactless cards issued outside the UK work, and both warn that overseas charges or transaction fees may apply.

Do you tap once, or tap on and tap off?

This catches people most often, because it flips depending on where you are.

Tap once (tap on only). In London, TfL's contactless conditions of use say that on buses and trams you only touch in at the start of each journey.

Tap on, tap off (often shortened to TOTO). Where a fare depends on how far you travel, the operator needs to know where you got off. First Bus asks you to tap at the start of your journey and tap off with the same card or device at the end. If you forget, First says you will be charged the single fare to the end of the route; if that leaves you overcharged, you can request a refund through its online portal. Gwynedd Council's Tap on-Tap off page describes the same two-tap pattern for buses in north-west Wales.

The practical habit: if you spot a second reader near the exit door, you are probably on a tap-off network, so get your card out before your stop.

How do contactless fare caps work on UK buses?

A fare cap is a ceiling on what you pay in a set period; once your taps reach it, further journeys in that period cost nothing extra.

In London, the TfL bus and tram fares page gives the adult pay as you go bus fare as £1.75, with a daily cap of £5.25 and a weekly cap (Monday to Sunday) of £24.70. The same page lists changes from 1 November 2026: £1.85 per journey, a £5.55 daily cap and a £26.10 weekly cap.

Outside London, caps are set operator by operator. First Bus describes its caps as making sure you never pay more than the price of a day ticket or week ticket, and those ticket prices differ between regions. Gwynedd notes that return fares are not currently capped under its Tap on-Tap off scheme, and that a return ticket should be bought from the driver in the usual way.

The most important cap rule was the same everywhere we checked: use one card or one device for everything. TfL's conditions say capping requires the same card or device for all your journeys in that day and week. First Bus says that if you use more than one card or device, each acts as a separate ticket with separate caps. Treat a phone and the card loaded into it as two different payment methods; TfL's conditions note that touching in with your phone and out with your watch or card is charged as two separate incomplete journeys.

TfL also warns about card clash, where the reader picks up the wrong card from your wallet. Tap with the paying card on its own.

Do caps and discounts carry over when you change buses?

London: TfL's Hopper fare gives you unlimited bus and tram journeys made within one hour of touching in, for the price of one adult pay as you go fare (£1.75 as of October 2026). Use the same card or device on every journey.
Multi-operator areas: Gwynedd says multi-operator caps such as 1Bws are applied across all bus companies on its tap scheme.
Everywhere else: do not assume. A cap on one company's buses may not count journeys on another company's buses in the same town. If your day involves two operators, read both pages or look for a multi-operator ticket. Our guide to planning a day out by bus covers choosing a ticket that is valid on every leg.

What counts as your ticket if an inspector gets on?

First Bus puts it simply: when you use tap on, tap off, your card acts as your ticket. What you need is the exact card or phone you tapped with, working.

TfL's conditions spell out the London position. You must be prepared to show your contactless card or device on every journey, and you may be asked to touch it on the inspector's portable card reader. If you are found not to have touched in, or your phone or device has run out of battery and cannot be read, you may be charged a maximum fare or a revenue inspection charge, given a penalty fare, or prosecuted.

Checks are common. In a June 2026 release, TfL reported that between April 2025 and March 2026 it checked 6.9 million contactless payment cards and 3.3 million bus passengers.

If you pay by phone, keep enough battery to get home. If it is already low, use the physical card all day instead, because switching mid-day splits your cap.

What happens if your card is declined or a payment fails?

TfL's conditions say a green light with one beep means the card has been accepted, and a red light with two beeps means it has been rejected; you must not go further until the card or device is accepted or you have paid by a different means.

Payments are often taken later, not at the moment of the tap. TfL charges your account after you have finished travelling for that day. First Bus says it processes payment later the same day and groups your journeys into a single payment, so one bank entry may cover several trips.

If that later payment is declined, the card can be blocked for future travel:

TfL says it will try again on up to three occasions, no more than once a day and for no longer than 30 days, and that the retry shows on your statement as TFL.GOV.UK/CP TFL UNPAID FA. Until unpaid fares are cleared, you cannot travel on that card. You can pay what is owed through your TfL online account.
First Bus says a declined payment is retried over the following days, and that your card will keep being declined for travel until the outstanding fare is paid. Its suggestion if a payment fails is to try a different card.

How does the national single fare cap fit in?

In England outside London, the government's national bus fare cap limits single fares on participating routes. The guidance, last updated 19 August 2026, says the £3 cap continues until the end of 2026, and that single bus tickets in England will be capped at £2 from 1 January 2027.

Participation is voluntary and some bus companies have chosen not to take part. Some route types, including coach, school-only and airport services, are not covered. London is excluded because its fares are capped locally. The page lists included routes by operator, so check yours before querying a charge.

Who should not pay by contactless at all?

On many networks, contactless pay as you go charges adult fares. First Bus says its tap on, tap off scheme is only available for adult fares, not child, student or group fares, and Gwynedd says its scheme charges the adult single fare. With children, buy the right ticket from the driver or the operator's app instead.

If you hold an older person's or disabled person's bus pass, use the pass, not your bank card. Tapping a bank card charges you a fare you may not owe. Our guide to the free bus pass in England explains who qualifies and how to apply.

Your five-minute check before you tap

On an unfamiliar network, open the operator's contactless page and confirm:

Accepted cards. Is your card type listed? First Bus, for example, does not take Amex or Maestro.
Tap rule. One tap or two, and the charge for a missed tap-off.
Caps. Daily, weekly or both, and when the week starts.
Transfers. Whether caps cover other operators.
Evidence. One card or device for the whole day, with battery to last.
Failed payments. How a decline is retried and cleared.
Backup. A second card kept separately, a little cash where drivers take it, or an app ticket bought the night before.

Most operators show your journey history online. TfL's account shows up to 12 months, and First Bus says journeys appear on its portal within a few hours. A quick look the next morning catches a missed tap early. For stops and times on a new route, our worked example on reading a UK bus timetable pairs well with this list.
