The first order of six Electrocity buses (based on VDL SB120 chassis) was placed by Transport for London for use on route 360 (operated by Go-Ahead Group subsidiary London Central)  and entered service in early 2006. These buses were meant to be the TransBus Enviro200H, but when TransBus went into administration in 2004, the bus side was bought by Alexander Dennis. The main aim for Alexander Dennis was to get the business out of trouble, so delivery of the Enviro200H was delayed. TfL eventually got impatient, and ordered the Electrocity. These were followed by a solitary bus in 2008 and then another six in 2011, bringing the total of Electrocitys operated by London Central to 13.
