This is a list of former municipal bus companies of the United Kingdom and a brief description of their fate, with the exception of the several municipals which disappeared in 1968 and 1974 with the formation of the PTE bus operations.

Of the remaining municipals, post-1986 many were sold off or collapsed during bus deregulation, which required their separation into stand-alone arm's-length companies.

Only a handful of municipal operators remain, with some securing their futures with equity partnership deals with private operators. Of the remaining operators, Cardiff Bus, Lothian Buses and Nottingham City Transport are the largest.

Former UK local authority-owned bus companies

The companies listed here were sold or ceased operating after 1986.

Yellow Buses, Bournemouth Yellow Buses was sold first to Transdev on 17 December 2005 for £15m, after the Liberal Democrat-controlled borough council decided that it could not satisfactorily invest in the company itself. Transdev returned ten percent of the equity to the council. The undertaking had been under municipal control or ownership for over 100 years. On 3 March 2011 the company became part of RATP Group as a consequence of that group's exit from its part ownership of Transdev. In July 2019 Yellow Buses was bought out from RATP by its management.

Burnley & Pendle Transport Burnley & Pendle was jointly owned by Burnley and Pendle borough councils. Liberal Democrat-controlled Pendle Borough Council's fifty-percent share was sold to Stagecoach in February 1996. At the time, Labour-controlled Burnley Borough Council stated that it had no intention of selling its share in the company, but it was not able to invest sufficient funds in the company and voted in October 1996 to sell its share to Stagecoach. Stagecoach was to sell the former Burnley & Pendle garage and operations to Blazefield Group in 2001. The Blazefield Group was bought by Transdev in 2006.
ChesterBus In June 2007 ChesterBus was sold to FirstGroup by the then Chester City Council. The sale process was longer than anticipated due to a court case against Arriva, which the council lost.
