Couch Bright King & Co came into being on 1st July 1970 with the amalgamation of the Uxbridge firm of Couch Bright & Co., with the London firm of Stanley King & Co., both firms having been established before 1930.  
The founding Senior Partners, Leslie Couch and Stanley King respectively, both coincidentally died in harness in 1960.
Each constituent firm had particular expertise in rather different areas of professional work which meant that the new amalgamated firm was able to offer a wider range of services to clients.

Since 1970 Couch Bright King & Co. has expanded in London, leaving Russell Square for more convenient and spacious accommodation in Gower Street in 1973. This lease ended in November 2017 so the firm relocated to Tottenham Court Road.

The lease of Tottenham Court Road came to an end in September 2022 so, with the increase in digital communications, the firm relocated to Maidstone, although a Central London office will always be available for meetings if required.
