Arriva Yorkshire was formed as a combination of mergers of previous companies based in West and North Yorkshire.

In 1904 Yorkshire (West Riding) Electric Tramways began operating tram services in Wakefield followed in 1906 by Castleford. In November 1923 the West Riding Automobile Company began operating bus services in West Riding. Yorkshire Woollen District Transport, meanwhile, operated services around Dewsbury.^[1]

Both companies were acquired by the National Bus Company, along with Selby & District with the companies maintaining separate identities.^[2] In 1987 West Riding Automobile and Yorkshire Woollen District were sold in a management buyout to Caldaire, under whose ownership they traded as West Riding Buses and Yorkshire Buses respectively.^[3][4] In 1994 South Yorkshire Road Transport, based in Pontefract, was purchased.^[1] The four companies were taken over by British Bus in 1995 which itself was purchased by Cowie Group in August 1996.^[1][5][6] All were rebranded under the Arriva brand in 1997.

From May 2008 until July 2021, there was a sister company in Huddersfield. Centrebus Holdings, in which Arriva held a 40% stake, was formed when the Huddersfield operations of Stagecoach Yorkshire was purchased along with the separate K-Line bus company.^[7] In September 2013, Arriva took full ownership of Centrebus Holdings and K-Line with the former rebranded Yorkshire Tiger and the latter as Tiger Blue.^[8][9][10] When Yorkshire Tiger was sold to Transdev Blazefield, routes 231 and 232 were not included and transferred to Arriva Yorkshire.^[11][12]

Arriva Yorkshire uses the Sapphire brand to differentiate premium services,^[13] with buses fitted with E-leather seats, free WiFi access, charging points, and audio-visual next stop announcements.^[14][15] Routes 110, from Wakefield to Leeds, 106, from Wakefield to Hall Green, 163 and 166, from Castleford to Leeds, 229, from Huddersfield to Leeds, and route 415, from Selby to York, are branded Sapphire.^{[citation needed]}

Arriva Yorkshire also formerly ran buses in Arriva Max branding, featuring similar premium features to Sapphire-branded buses. Services were also marketed as "Grand Yorkshire Connections", emphasising the larger network of branded routes.^[16] This branding is being phased out as a result of the rebranding of the wider Arriva operation in 2017.

The third sub brand used by Arriva was the high-frequency Frequenta, formerly used on routes 148 and 149 between Wakefield, Pontefract and Knottingley, with services timetabled to run every 10 minutes.^[17][18]

A widely reported^{[by whom?]} case in 2008 concerned a gothic couple, Dani Graves and his fiancée Tasha Maltby, who wears a dog collar and lead.^[19] A driver had refused them travel and made comments to them, allegedly saying "We don't let freaks and dogs like you on." The company confirmed the couple were refused travel on two occasions due to "fears for passenger safety". In a statement the company addressed the issue, claiming that the dog lead was potentially dangerous. Arriva also said they would be writing to Mr Graves "to apologise for any distress caused by the way this matter was handled".^[20]

In January 2017, a wheelchair user was denied access to a Arriva Yorkshire bus by the driver, because a pushchair was occupying the wheelchair space. The incident occurred days after the Supreme Court ruled that drivers should prioritise the space for wheelchair users.^[21]

As of December 2017, the Arriva Yorkshire fleet consisted of 334 buses.^{[needs update]} The company operates buses from five depots in Castleford, Dewsbury, Heckmondwike, Selby and Wakefield.
