[3] Services expanded rapidly after the Second World War as new housing estates grew in areas such as Orford and Great Sankey.

The department also began operating new services jointly with Crosville upon the split of the old Stockport based North Western Road Car Company in 1972.

Merseybus' Lancashire Travel subsidiary competed with Warrington to a lesser extent, focusing on a core of 4-5 routes in the Callands and Westbrook areas near its St Helens depot in the South West of the town.

In retaliation to MTL & North Western, Warrington Borough Transport commenced operating services to places such as Wigan, St Helens, Widnes, Runcorn, Chester and Liverpool, as well as commencing a local minibus service in Northwich,[4] receiving support from neighbouring fellow municipal Halton Transport.

[9][10] In 2006, the company was rebranded and became known as Network Warrington, with a new livery designed by Samantha Beeley introduced onto the operator's bus fleet.

[11][12] This rebrand coincided with a streamlining of other routes, both long distance and in the town centre, which were operated with increased frequencies to shorten journey times.

The two main sheds to the rear of the site were originally built in 1943 for Fairey Aviation and used to assemble wings for their Fulmar bomber until they were purchased by Warrington Corporation in 1947.

Warrington Borough Council secured £21.5 million of funding from the central government's Zero Emission Bus Regional Areas (ZEBRA) scheme to replace the entire Warrington's Own Buses fleet with 105 Volvo BZL single and double-decker battery electric buses bodied by MCV Bus and Coach.

[24][25] Following a launch event held by council leaders in March 2024,[26][27][16] the first of these buses began to enter service from July 2024 onwards.
