Arriva Northumbria operates in Northumberland, using the "Arriva serving Northumbria" name. They are considered now to have merged with Arriva North East.
United Automobile Services split into two parts in 1986, making it ready for privatisation.
In October 1987 Northumbria was bought from National Bus Company by its management, using Proudmutual Group as a holding name.
In March 1988 Proudmutual Group bought Kentish Bus.
Moor Dale Coaches and Hunters were acquired.
In 1994 the Proudmutual Group was bought by British Bus, and at the same time, Moor Dale Coaches was sold back to its former directors.
British Bus was acquired by Cowie Group, and later renamed Arriva.[1]
The point at which Cowie buys British Bus is where the history of Arriva North East gets involved.
