The company was founded in 1928 by Ralph Bullock, initially as a haulage firm, with milk deliveries being the early focus.
The firm remained small with around 20 vehicles, until 1986, when deregulation of the bus market allowed Bullocks to diversify.
In October 2013, Bullocks purchased the Finglands Coachways coach charter business from East Yorkshire Motor Services.
[7] Bullocks also operate the Trafford General and Wythenshawe Hospital shuttles from the Manchester Royal Infirmary.
[8][9][10] As well as coaches, Bullocks formerly operated four Wright Eclipse Gemini 2 bodied Volvo B5Ls on route 147,[11] In 2018 these passed to Lothian Buses[12] in exchange for several Scania Omnicities, which will be used on school services.
