No, you do not touch out (touch off) on London buses. The London bus system operates on a "Flat Fare" model, meaning the price is the same regardless of how far you travel. You only need to "Touch In" on the yellow card reader with your Oyster card, contactless bank card, or mobile device (Apple Pay/Google Pay) when you board. If you attempt to touch out at the end of your journey, you may accidentally be charged for a second journey or "incomplete" fare. In 2026, the "Hopper Fare" remains a high-value feature: after you touch in on your first bus, you can make unlimited bus or tram transfers for free within 60 minutes. This rule is different from the London Underground (Tube) or the Elizabeth Line, where you must touch out at the gates to ensure you are charged the correct zone-based fare and to avoid a "Maximum Fare" penalty.
