London operator
Metroline was the first company to order the Enviro400, ordering 28 for
route 24 in June 2005, entering service at the end of the year. One dual door demonstrator, named
Spirit of London, was delivered to
Stagecoach London to replace the Dennis Trident destroyed during the
7 July 2005 London bombings and a single door demonstrator was delivered to the then
Travel West Midlands for evaluation. Both prototypes were exhibited at Coach & Bus Live 2005 in the
National Exhibition Centre in
Birmingham.
FirstGroup received a large intake of Enviro400s ahead of both the
2012 Summer Olympics and the
2014 Commonwealth Games, which were held in
London and
Glasgow respectively. These operated under the license of First Games Transport, providing shuttle services throughout the Games before being dispersed to other operators within the group following the Games' conclusion. 60 Enviro400s were delivered to Glasgow in 2014. Later in 2014, eighteen Enviro400s were delivered to
First West Yorkshire for operation in
Leeds. In 2008, a specially converted Enviro400 was assembled in
knock-down kit form for the
closing ceremonies of the
2008 Summer Olympics and
2008 Paralympic Games in
Beijing. The bus featured as part of the handover ceremony for the
2012 Games, where it was driven into the
Beijing National Stadium as a typical London bus before a set of hydraulic pumps opened up the bus, revealing a stage covered in artificial grass which was shaped as various London landmarks. In 2012,
Southern Vectis received 20 for school contracts on the
Isle of Wight. These were delivered during late December 2012 and early January 2013 and entered service on a wide variety of school services on the island from 7 January 2013. Southern Vectis then proceeded to order ten more Enviro400s to be used on public routes, mainly route 9, which entered service in January 2014, followed by another order for ten Enviro400s which were delivered in 2016.
Enviro400H Enviro400 Hybrid in the company's hybrid livery in
Sheffield Alexander Dennis launched the
hybrid electric Enviro400 Hybrid (often shortened to
Enviro400H) at the 2008 Euro Bus Expo, built with a hybrid drivetrain developed in partnership with
BAE Systems. The first five production examples entered service with Metroline, followed by larger fleets of Enviro400Hs entering service with operators such as
Go-Ahead London,
London United,
Abellio London and
Stagecoach London. Outside of London, the Enviro400H was popular with the Stagecoach Group who, starting in 2010, ordered examples delivered in a green variant of the standard Stagecoach livery for their
Stagecoach Oxfordshire,
Stagecoach Yorkshire,
Stagecoach Manchester, and
Stagecoach North East subsidiaries. Other operators who purchased Enviro400Hs included the National Express West Midlands and
National Express Dundee, ordering a total of nineteen for service in
Birmingham and
Dundee in 2013;
East Yorkshire Motor Services, who purchased ten for cross-city services in
Kingston upon Hull in 2011;
Reading Buses, who had 31 Enviro400Hs delivered between 2010 and 2011; the
Oxford Bus Company, who took on examples to upgrade its
park & ride fleet, and
First Glasgow. However, reliability issues and maintenance costs have seen many operators convert their Enviro400Hs to use diesel powertrains, with East Yorkshire providing most of these conversions, while Reading Buses converted one of their Enviro400Hs to a plug-in electric vehicle. Further Gold-specification Scania-ADL Enviro400s were delivered throughout the type's production run to operators such as
Stagecoach in Oxfordshire,
Stagecoach Midlands for their
X4 service, and
Stagecoach Yorkshire. Scania N230UDs with Enviro400 bodies fitted with guide wheels were also purchased for use on the
Cambridgeshire Guided Busway, with the first buses delivered in 2009 prior to the opening of the Busway in 2011, followed by additional Enviro400s being purchased in 2014 and 2015. Elsewhere, conventional specification Scania N230UDs with Enviro400 bodies were purchased for certain Stagecoach divisions, including 22 examples for
Stagecoach Devon for use on the North Devon Wave service in 2013, and five examples for
Stagecoach in Lincolnshire in 2012 for
Lincolnshire InterConnect services. Another significant operator of Scania Enviro400s is
Nottingham City Transport, who ordered a total of 62 Scania N230UD Enviro400s, with first deliveries beginning in 2014. Further examples were delivered throughout 2014 and 2015, with most receiving colour-coded route branding for services across the city. These Scania Enviro400s were delivered with audio-visual next stop announcements,
mood lighting and leather seating. The
Oxford Bus Company received eleven high-specification Scania Enviro400s in 2009 for service on the Brookesbus network. Wilts & Dorset also received some examples. Two were delivered to independent operator
Stephensons of Essex in 2013.
Volvo Enviro400 On 13 October 2006,
Solent Blue Line received a
Volvo B7TL/Enviro400 meeting the Euro III emission standard, with the interior in
Wilts & Dorset livery. This remains a one-off as all subsequent Enviro400s on
Volvo chassis were built on the B9TL chassis. An Arriva demonstrator was shown at Euro Bus Expo in 2006 to the latter standard. Irish municipal operator
Dublin Bus was the first operator to order the
Volvo B9TL-based Enviro400, taking delivery of 100 on the updated Volvo chassis in two batches between 2007 and 2008. East Yorkshire Motor Services later took delivery of five Enviro400-bodied
Volvo B9TL in December 2007, which entered service in January 2008. London General also received three Enviro400-bodied Volvo B9TLs in October 2008, which were evaluated against integral Enviro400s and
Wright Eclipse Gemini-bodied Volvo B7TL and B9TLs extensively featured in
Go-Ahead's London Central and General fleets. No further orders resulted in the United Kingdom, although London General's Enviro400s were briefly loaned to
Arriva London North for evaluation ahead of delivery of their
Volvo B5LHs. ==Exports==
