The Electrocity was based on DAF/VDL SB120 chassis for most of these buses, except for a single Dennis Dart SLF prototype.

The bodywork design was similar to the existing Wright Cadet and Crusader, which were also built on DAF SB120 and Dennis Dart SLF chassis respectively, with the addition of battery pods on the roof of the Electrocity being the main difference.

Following the collapse of TransBus International in 2004 and subsequent cancellation of the Enviro200H programme, in February 2006 London Central placed six Electrocitys based on VDL SB120 chassis into service on route 360.

[6][7] Externally they received larger white pods on the rear roofs to house the batteries.

[8][9] A single Electrocity was built for London Central in 2008, followed by a batch of six in 2011, to allow for a full conversion of route 360.
