RATP Dev London

What RATP Dev London does

RATP Dev London, now operating as First Bus London following its 28 February 2025 acquisition by FirstGroup plc, is one of the largest bus operators in London. The company runs 82 bus routes, mostly under seven-year contracts awarded by Transport for London (TfL) through competitive tendering, from ten operational bases (nine garages plus Park Royal) using a fleet of approximately 927 vehicles. It carries around 210 million passenger trips annually and employs 3,700 staff across driving, engineering, control and support functions. Its diverse end-user base spans commuters, tourists, schoolchildren, hospital patients and accessibility-needs passengers.

The company's core technology is conventional public bus transport operations combined with a significant electric vehicle infrastructure programme. Over 46% of the in-service fleet is zero-emission, with 23 electric routes operated from six converted garages (Shepherd's Bush, Harrow, Fulwell, Hounslow Heath, Westbourne Park and Edgware), and the business is targeting a fully electric fleet by 2030 — four years ahead of the Mayor of London's 2034 mandate. Supporting assets include four state-of-the-art operational control centres opened in 2023, mobile applications on iOS and Android, on-bus CCTV (since 2000), and a Tower Transit joint venture at Westbourne Park Garage. The company has no disclosed proprietary AI/ML or software platform; technology differentiation is operational rather than digital.

Revenue is generated under two intertwined streams: contracted payments from TfL for operating routes awarded via competitive tender (managed services), and fare revenue from approximately 210 million passenger trips annually, with pricing governed by TfL's unified fare structure. Ancillary revenue streams include advertising on London buses and commercial bus hire for film and photography. GTM is effectively enterprise field sales into TfL at the contract-award level, with passenger acquisition handled organically via route coverage, the First Bus mobile app, and the firstbus.co.uk website. Strategic positioning is anchored on operational scale, sustainability leadership through electrification, and contract reliability within London's regulated bus market.
