The first Enviro400 in London was delivered to Stagecoach London in December 2005 to replace the bus that was destroyed in the 7 July 2005 bombings, the bus was named the “Spirit of London” as a result and numbered 18500 by owner, Stagecoach London.

Alexander Dennis released a facelifted version of the first generation Enviro400 in 2009, with the main external visual differences being the incorporation of a line of white LED daytime running lights underneath the headlights in the main front light clusters, redesigned front bumpers and the relocation of the offside emergency exit door.

Production of the original & facelifted Enviro400 ceased in 2015 with the release of the Enviro400 MMC and Enviro400H City.
