Centra was one of many operators of London Buses. They were the transport division of Central Parking Systems of UK Limited (CPS) who acquired the assets of Wimco Group Coaches Limited (which has been trading as Mitcham Belle) in August 2004. The company ran its last passenger services on 19 May 2006. In a separate operation, Centra also ran buses in Surrey and around Heathrow and Gatwick airports, after purchasing Thames Bus in October 2003. This division lasted two years before being sold to Flights Hallmark in 2005.
