The Freedom of the Borough is the highest honour that a council can award.

The council granted the Freedom of the Borough to The South Lancashire Regiment (The Prince of Wales's Volunteers) on 17 September 1947 in recognition of the long and close association existing between Warrington and the Regiment. The successor to the Regiment, the Queen's Lancashire Regiment, became the The Duke of Lancaster's Regiment (King Lancashire & Borders) in July 2006.

As such The Duke of Lancaster Regiment has permission to march through the streets of Warrington with drums beating, bands playing, colours flying and bayonets fixed.

Mrs VI Edwards and Mr H Cunningham were both granted Freedom of the Borough in recognition of their eminent services to the borough of Warrington in October 1997.
