How Many Buses Does Transport for London Operate?

As of 2023, Transport for London (TfL)—the integrated transport authority—operates a fleet of over 9,000 buses across more than 675 routes.

Key facts:

• All buses are low-floor, wheelchair accessible, and meet Euro VI emissions standards.
• ~3,000 are hybrid/electric/hydrogen; TfL targets a fully zero-emission fleet by 2034.
• The network carries ~2 billion passenger journeys annually (pre-pandemic peak).
• London's iconic red double-deckers (New Routemaster, etc.) are a minority; single-deck and articulated buses dominate.

Historical note: The London Passenger Transport Board (1933–1947) was the predecessor; "London Transport" as a brand ceased in 1984.
