At the end of February 2025, FirstGroup Plc completed its acquisition of RATP Dev Transit London, which now operates as First Bus London. This strategic moves sees First Bus London join First Bus, strengthening the latter's position as a leading provider of sustainable bus operations in the UK and Ireland.
Whilst originally planning to retain he RATP Dev fleet numbers, an early decision was taken to renumber the fleet into the First Bus national series. This exercise is now complete and whilst the new numbers are yet to be applied to the vehicles, they are in use for internal fleet management and engineering purposes and serve to eliminate duplication between the RATP Dev and First Bus systems. This supplement to the 2025 First Bus Handbook provides a full correspondence table between the two sets of numbers, and illustrates the application of the Firstbus fleet names to the London operations.
