Do I need cash in the UK, or can I use cards?
Short answer: you can do the whole trip without cash. Contactless runs everything, including all of London's transport, and many places no longer take notes at all. Here is how to pay, and the couple of things to get right.

Cash for
Rarely, a few small places
Cards, almost entirely. The UK is one of the most cashless places on earth, so you can tap a card or phone nearly everywhere, and some shops no longer take cash at all. All of London's transport runs on contactless, and buses across the UK take no cash whatsoever. You do not need an Oyster card: tapping your own contactless card or phone charges the same fares and caps. Keep maybe 20 to 40 pounds for the rare cash-only spot, and choose pounds, not dollars, at the terminal.
You barely need cash
In 2026 the UK is nearly cashless. Contactless is accepted almost everywhere, by card or phone, and plenty of cafes and shops are card-only, some genuinely cannot make change. You can comfortably leave home with no pounds at all and get them from a cash machine if you want a little.
The main quirk is the 100 pound contactless limit most UK banks still apply: above that a card asks for chip and PIN, though paying with your phone (Apple Pay or Google Pay) has no such cap. Keep a small amount of cash, 20 to 40 pounds, only for the occasional rural pub, market stall or tip.
London transport: just tap
This is the big one for visitors. All London buses stopped taking cash years ago, and the Tube, Overground and Elizabeth line all work by tapping a contactless card or phone at the gate. The system automatically applies the same daily and weekly fare caps as an Oyster card, so you always pay the cheapest fare, which means you do not need to buy an Oyster at all.
Two small habits: tap in and tap out on the Tube and trains (buses are tap-in only), and do not tap a whole wallet against the reader, hold out the single card or phone you mean to use, or it may charge the wrong one.
Getting cash, and the dollar rule
If you want cash, use a free-to-use cash machine (most bank ATMs and the wider LINK network are free), and avoid the fee-charging machines tucked in some convenience stores. Apple Pay and Google Pay are accepted essentially everywhere cards are.
When a UK card machine or ATM asks whether to charge in US dollars or pounds, always choose pounds. Picking dollars triggers dynamic currency conversion at a poor rate. Pounds lets your own bank do the conversion, which is cheaper.
Tipping, and one note
In restaurants a service charge of around 12.5% is often added to the bill; it is discretionary, so you can ask for it to be removed if service was poor, and you need not tip on top. In pubs where you order at the bar, tipping is not expected.

Common questions
Quick answers.
Do I need cash in the UK?
Barely. The UK is nearly cashless: you can tap a card or phone almost everywhere, and many places are card-only. A whole trip with no cash is realistic. Keep maybe 20 to 40 pounds for the occasional rural pub, market stall or tip, and get it from a free cash machine if needed.
Do I need an Oyster card, or can I use contactless?
You can use contactless and skip the Oyster. Tapping your own contactless card or phone on London's Tube, buses and trains charges the same fares and applies the same daily and weekly caps as an Oyster, so there is no saving from buying one. Just tap in, and tap out on rail.
Can I use cash on London buses?
No. London buses have not accepted cash since 2014, and in 2026 no bus anywhere in the UK takes cash. You pay by tapping a contactless card or phone, or an Oyster or travelcard. On buses you tap in only, there is no need to tap out.
Should I choose pounds or dollars at the card machine in the UK?
Always choose pounds. Selecting US dollars triggers dynamic currency conversion, a marked-up rate, so you pay more. Choosing pounds lets your own bank handle the conversion at a better rate. The same applies at cash machines: decline any offer to charge in dollars.
More on United Kingdom
The little money things nobody warns you about.
- Tipping in the UKThe UK tips more than most of Europe but far less than the US. The main thing to watch is the discretionary service charge already on restaurant bills, which is optional. Here is what you actually owe.
- Do US citizens need an ETA for the UK?Short answer: yes, now you do, and it even applies to a layover. The UK ETA is not a visa, and it is quick and cheap, but only from the official source. Here is what it costs and how to get it right.
- Bringing your dog or cat to Great Britain.Compared with Japan or Australia, the UK is quick: the lead time is weeks, not months, because there is no rabies blood test for pets coming from the US. The cost surprise is the flight, since pets almost always travel as cargo into Britain, not in the cabin. Here is the order, the official route, and what to budget.
- Can tourists get a VAT refund in the UK?Short answer: no, not in England, Scotland or Wales. This is the opposite of what most European trips teach you, and it catches shoppers out at Heathrow. Here is what changed, and the only two ways left to shop tax-free.
- Staying connected in the UK.The UK is easy: coverage is excellent almost everywhere, including on the Underground now. The only real decision is how you pay for data, and for most US travelers an eSIM is far cheaper than the carrier day pass. Here is the math.
- London taxis, Uber, and the Heathrow transfer.London gives you real choice: a hailable black cab or a pre-booked Uber. But the money is made or lost on the airport run, where the train quietly beats a cab by fifty pounds or more. Here is how it all compares.
