Using London Bus Tickets on the Tube: Rules and Restrictions

Yes, but with significant limitations. A London bus ticket can be used on the Underground (Tube) only under specific conditions:

Strict Requirements

• Single ticket only: Return tickets are not accepted
• Unused on bus: Must not have been previously validated on a bus journey
• Valid/non-expired: Within its validity period

How It Works

If all conditions are met, insert the paper ticket into the Tube station ticket barrier. It will grant entry. This is a legacy provision from when paper tickets were more interchangeable.

Practical Reality

Most travelers should not rely on this. Modern London travel uses:

• Oyster cards / Contactless payment: Pay-as-you-go across bus, Tube, rail, DLR, tram
• Travelcards: Unlimited travel for set periods (day, week, month)
• Bus & Tram Passes: Bus-only (cheaper than Travelcards)

Key Differences

For any regular or multi-leg travel, Oyster or contactless is cheaper, faster, and more flexible. The bus-ticket-on-Tube option is a narrow exception, not a general practice.
