London’s public‑transport system is one of the most sophisticated in the world, but that doesn’t make it easy to navigate.
Between pay‑as‑you‑go cards, contactless bank cards, paper tickets and season passes, visitors and locals alike often end up overpaying or missing out on discounts.
This guide – updated for August 2025 breaks down the differences between Oyster cards, contactless payments and Travelcards, shows when each option makes sense, and highlights money‑saving hacks that London insiders use every day.
1. Pay as you go with a contactless card or phone
Why use it:
No extra card to buy. If you already have a contactless UK debit/credit card or a mobile wallet (Apple Pay/Google Pay), you can tap straight away. This avoids the £7 Oyster card fee and means you don’t have to queue at ticket machines.
Automatic capping. TfL charges fares overnight and will never bill you more than the daily cap (£8.90 for zones 1–2) or weekly cap (£44.70). Once you hit the cap, further journeys that day or week are free.
Flexible and sometimes cheaper. Because contactless capping is based on the zones you travel through, occasional long journeys from outer zones can sometimes come in slightly cheaper than Oyster capping.
Use your phone as a second card. You need one card per passenger; however, adding the same bank card to a phone wallet effectively gives you a second card – handy for couples or families.
Watch out for:
Foreign‑issued cards. Some non‑UK bank cards won’t work, and others charge foreign‑transaction fees. If you’re visiting from abroad, check with your bank or consider a Visitor Oyster card.
No concessions. Contactless cannot store Railcard discounts or child/student fares. If you have a Railcard or are travelling with children aged 11–15, an Oyster card is better.
Card clash. Keep only one contactless card near the reader; multiple cards in a wallet can trigger “card clash”, resulting in double charging. Always take the card or phone out of your wallet before tapping.
Weekly caps reset on Mondays. The weekly cap only counts journeys made between Monday and Sunday. If your trip starts mid‑week and you’ll travel heavily, a 7‑day Travelcard may be cheaper.
Hacks:
Plan big sightseeing days at the start of the week to hit the weekly cap and travel free for the rest of the week.
Register your card on TfL’s website. This lets you view journey history, spot errors and claim refunds for incomplete journeys or card‑clash charges.
Use the same card/device throughout your trip. Switching between a card and its digital wallet counts as two separate cards and resets the capping.
If travelling with only one card between two people, one person can use the physical card and the other can use the phone wallet.
2. The Oyster card: London’s classic travel pass
Why use it:
Universally accepted. Oyster works on Tube, buses, trams, DLR, London Overground and most National Rail services within London. It also supports pay‑as‑you‑go on river buses and the cable car.
Supports travelcards and discounts. Railcards (e.g., 16–25, Senior, Disabled) can be loaded to an Oyster, giving a one‑third discount on off‑peak fares. Visitors travelling with children can add a Young Visitor discount to give 50% off adult fares.
Works for cash. You can top up with cash at stations and licensed shops; this avoids foreign‑transaction fees.
Seven‑day flexibility. A 7‑day Travelcard loaded on an Oyster is valid for any seven consecutive days, unlike contactless weekly caps which run Monday–Sunday.
Costs and caps:
The card itself costs £7. The deposit is no longer refundable, so treat it as a one‑off purchase.
Fares are identical to contactless; off‑peak Tube trips in zone 1–2 cost £2.80 and you will never pay more than the daily (£8.90) or weekly (£44.70) cap.
Disadvantages:
Top‑ups required. Without enough credit the card will refuse entry; topping up is easy at Tube stations but harder at bus stops.
Left‑over credit. Because fares vary, it’s difficult to end with a zero balance; millions of pounds sit on unused Oysters. Register your card to claim unused credit when you leave London.
Not valid for taxis or certain private services. You can’t pay for black cabs using an Oyster.
Hacks:
Add a Railcard for off‑peak savings. If you own a 16–25, Network or Senior Railcard, linking it to your Oyster gives a 34% discount on off‑peak fares.
Use pink card readers. If you’re travelling across London via a route that avoids zone 1, touch the pink readers at interchange stations to tell the system your route and avoid being charged for zone 1 fares.
Young Visitor discount. Parents can have a TfL staff member add a 50% discount to a child’s Oyster for up to 14 days.
Get refunds and protect your card. Register your Oyster online; this lets you set up auto top‑up, block lost cards and reclaim remaining credit.
3. Travelcards and season tickets
A Travelcard is a pre‑paid pass valid for unlimited travel within certain zones for a set period (1 day, 7 days, 1 month or 1 year). Travelcards can be loaded onto an Oyster or issued as paper tickets from National Rail stations.
One‑day Travelcard
An off‑peak paper Travelcard covering zones 1- 6 costs £16.60; peak‑time versions cost more (for example, £23.60 for zones 1- 6).
- When using pay‑as‑you‑go, the daily cap for zones 1–2 is £8.90, so a Travelcard is only good value if you plan to travel further out or take lots of journeys across multiple zones in one day.
Seven‑day Travelcard
Costs are identical to weekly pay‑as‑you‑go caps. A 7‑day Travelcard for zones 1- 2 costs £44.70, zones 1- 3 £52.50, and zones 1–6 £81.60.
Unlike contactless caps, the Travelcard can start on any day and lasts for seven consecutive days. This makes it useful for visitors arriving mid‑week who plan to travel every day.
Travelcards loaded onto an Oyster do not qualify for 2‑for‑1 attraction vouchers; only paper Travelcards bought at National Rail stations do.
Monthly and annual Travelcards
A monthly Travelcard for zones 1- 2 costs £171.70. It makes sense only if you commute almost every day; remote‑working Londoners often find contactless weekly capping cheaper.
An annual Travelcard (zones 1- 2) works out at £1,708 per year, or about £6.83 per day. It may be worth it if you travel nearly every day, including weekends.
Travelcard perks – 2‑for‑1 deals
One of the best uses of a paper Travelcard is to unlock 2‑for‑1 entry to major attractions. National Rail’s Days Out Guide offers vouchers for sights like the Tower of London, City Cruises and St Paul’s Cathedral. To qualify you must present a paper Travelcard bought from a railway station (with the National Rail logo) along with a printed voucher. Travelcards loaded onto Oyster cards or bought at Tube ticket machines don’t count. The off‑peak zone 1–6 Travelcard at £16.60 can therefore pay for itself with a single 2‑for‑1 attraction.
4. Bus & tram hacks: the Hopper fare
Bus and tram fares in London are uniform across the city. The Hopper scheme introduced by the Mayor allows unlimited bus and tram journeys within one hour for £1.75. After you hit the daily cap of £5.25 or the weekly cap of £24.70, the rest of your bus journeys are free.
How it works:
Tap in on the first bus or tram; you won’t pay again for any additional bus/tram rides started within 60 minutes. Use the same card or device for all journeys.
If you change to the Tube, DLR or Overground between bus journeys you’ll pay the rail fare, but the Hopper still applies to subsequent bus rides within the hour.
If your Oyster card goes into negative balance after the first tap, the Hopper fare won’t apply until you top up.
Hacks:
Plan routes with bus transfers inside an hour to cut costs on cross‑town trips.
Combine the Hopper with a daily or weekly cap to make bus travel almost unlimited; after you reach £5.25 (daily) or £24.70 (weekly) you pay nothing more.
5. Money‑saving tips and common pitfalls
Avoid card clash and double scanning. Keep your Oyster or contactless card separate from other cards; otherwise the reader may charge multiple cards.
Always tap in and out. Even if gates are open, you must touch the yellow reader at the start and end of each journey; forgetting can result in a maximum fare. Use the TfL app to claim refunds for incomplete journeys.
Check peak and off‑peak times. Peak fares apply Monday–Friday 6:30–9:30 am and 4–7 pm; off‑peak fares are cheaper and all‑day on weekends. Travelling after 9:30 am can nearly halve the cost of your journey.
Use pink readers to avoid Zone 1. If you’re crossing the city via an orbital route (e.g. Overground), touching the pink reader tells the system you avoided zone 1 and charges you accordingly.
Combine Railcards and Oyster. If you have a National Rail Railcard, link it to your Oyster to get one‑third off‑peak Tube, DLR and Overground fares. You can’t apply these discounts to contactless.
Children travel free for half price. Up to four children under 11 travel free on the Tube, DLR, Overground and Elizabeth line when accompanied by an adult with a valid Oyster card. Children aged 11–15 can get a Young Visitor discount giving them 50% off fares.
Paper Travelcards for attractions. Use a paper Travelcard from a National Rail station to unlock 2‑for‑1 offers at over 60 attractions.
Check your bank. Some banks block London transport transactions from abroad or charge extra fees; consider a fee‑free travel card or a Visitor Oyster card.
Which option should you choose?
Most visitors with a UK card or mobile wallet: Use contactless. It’s simple, there’s no up‑front fee and you’ll benefit from daily and weekly capping without planning ahead.
Visitors without a UK card, or travellers with Railcards/children: Get a standard or Visitor Oyster card. You can load discounts, purchase 7‑day Travelcards and avoid foreign‑transaction fees.
Heavy sightseeing over a short period: A paper One‑day Travelcard can be worth it when combined with 2‑for‑1 vouchers. A 7‑day Travelcard makes sense if your trip starts mid‑week and you’ll travel every day.
Commuters and locals: Compare the cost of a monthly or annual Travelcard to your actual journey patterns. Remote workers often find that pay‑as‑you‑go weekly caps are cheaper.
TfL’s system is designed to make pay‑as‑you‑go the default.
For most people, using a contactless card or phone will cost the same as (or less than) an Oyster card, and you won’t have to worry about topping up. However, an Oyster card still has its place: it supports travelcards, concessions and visitors without UK bank cards.
Travelcards can be worthwhile when combined with attraction deals or when your travel patterns fall outside the Monday – Sunday cap. Finally, don’t forget the little hacks – like the Hopper fare, pink readers and Railcard discounts – that can shave a few more pounds off your London adventures.
