The coach business was established by H.R. Richmond in 1920 and operates a fleet of mostly Setra coaches.
In 1986 Epsom Coaches made the move into the bus market. In 2003, Epsom Coaches decided to rebrand its bus division as Quality Line and repainted its vehicles from their traditional cream and brown into allover red to comply with Transport for London requirements. On 19 April 2012 Epsom Coaches was purchased by the RATP Group.
