London Underground Contactless vs Oyster: 2026 Daily & Weekly Capping Guide
Complete 2026 London Underground fare guide. Learn how Contactless payment works, Zones 1–6 daily caps, Monday-to-Sunday weekly capping, and card clash rules.
- ✓Contactless bank cards and Apple Pay / Google Pay have made physical Oyster cards obsolete for 95% of international tourists in London, offering identical lowest fares with zero £7 card deposit fees.
- ✓TfL Daily Fare Capping: No matter how many tube, bus, DLR, and Overground trips you take in a single day, your total spend is strictly capped (e.g. £8.50 for Zones 1–2).
- ✓Monday-to-Sunday Weekly Capping: If you tap using the same contactless card from Monday 04:30 through Sunday night, total fares are capped at the official 7-day travelcard rate (e.g. £42.70 for Zones 1–2).
- ✓Card Clash Warning: Always take your physical card out of your wallet or use a specific phone card to tap in and tap out; tapping an entire wallet can charge two cards simultaneously or register incomplete journey penalties.
Navigating the London Underground (the Tube), Elizabeth line, DLR, and iconic red double-decker buses is one of the most efficient transit experiences in Europe.
However, many international visitors still waste time and money buying outdated physical Oyster cards or paper Day Travelcards without understanding how TfL Contactless Pay & Automatic Fare Capping works.
This 2026 guide explains the exact mechanics of daily and weekly price capping, foreign card transaction fees, and how to avoid the dreaded “Card Clash” error.

2. TfL Daily Fare Capping Table (Zones 1 to 6)
No matter how many times you ride the Underground, Overground, Elizabeth line, or DLR in a single transit day (04:30 to 04:29 next day), your card will never be charged more than the official cap:
flowchart LR
Tap1[Ride 1: Zone 1 Tube - £2.80] --> Tap2[Ride 2: Zone 1-2 Tube - £2.80]
Tap2 --> Tap3[Ride 3: Zone 1 Tube - £2.80]

|---|---|---|
| Zones 1 – 2 (Central London tourist sights) | £8.50 | ~3 Tube rides |
| Zones 1 – 3 (e.g. Greenwich, Wimbledon) | £10.00 | ~3–4 Tube rides |
| Zones 1 – 4 (e.g. Wembley Stadium, Richmond) | £12.30 | ~3–4 Tube rides |
| Zones 1 – 6 (Includes Heathrow Airport) | £15.60 | ~2–3 long distance rides |
| London Bus / Tram Only Cap (All Zones) | £5.25 | 3 Bus rides (£1.75 flat fare) |
3. Monday to Sunday Weekly Capping Explained
If you are staying in London for 4 to 7 days, TfL automatically tracks your contactless card spending across the calendar week (running strictly from Monday 04:30 AM through Sunday night):
- Zone 1–2 Weekly Cap: £42.70 (equivalent to roughly 5 days of daily caps; weekends are effectively free!).
- How It Works: You do not need to choose a pass upfront. The system simply stops charging your card once cumulative daily deductions reach £42.70.
- Important Gotcha: Weekly capping strictly operates on a Monday-to-Sunday schedule. If your 7-day trip begins on a Thursday and ends the following Wednesday, daily capping still applies, but weekly capping will not bridge across two different calendar weeks.
4. Step-by-Step: Tapping In and Out Correctly
Using Contactless on London Public Transport
Prepare Your Device or Plastic Card
Station TurnstilesHave your contactless Visa/Mastercard/Amex or smartphone (Apple Pay / Google Wallet) ready before approaching the fare gates. Enable Express Transit mode on iPhone for screenless tapping.
Tap Yellow Card Reader & Enter
TfL Fare GatesTap your card or phone flat against the bright yellow circular reader. The gate displays a green light and opens immediately.
Always Tap Out with the EXACT Same Card
Destination Exit GateAt your destination, tap out with the identical card/phone you used to enter. This ensures TfL calculates the precise zone fare rather than charging a maximum incomplete journey penalty (£9.60+).
5. Summary Checklist: The 4 Rules for London Transit
- 💳 Use Contactless over Oyster: Skip the £7 card deposit and tap your credit card or Apple Pay directly.
- 🔄 Always use the same device: Do not mix between your physical plastic card and Apple Watch; TfL tracks each device identifier separately.
- 🚌 Never tap out on buses: Tap in only once when boarding red buses.
- ⏱️ Take advantage of the Hopper Fare: Ride unlimited buses and trams within a 60-minute window for a single £1.75 fare.
