Blazefield commenced operations in 1991, having bought the final shares in the former AJS Holdings group. From the beginning it was clear that Blazefield had a strong approach to passengers and the growth of the business. With over 300 vehicles, most of the operations were in Yorkshire with a base in London for its Sovereign unit along with a smaller operation based in and around Cambridge.

Route branding and a simple livery was a combination that worked well for increasing passengers and vehicle renewal. The Volvo chassis range and Wrightbus bodywork were the standard for the group. Growth came in the shape of the former Stagecoach operations in East Lancashire. In late 2006 Transdev were successful in acquiring Blazefield.

Transdev continued to form a strong brand. Today expansion in local identities along with colourful brands see Transdev taking the lead in modern-day bus operation.
