Capital London is an Independent Local Radio station owned and operated by Global Media & Entertainment as part of its national Capital Network.

The Capital Gold radio station started in London in 1988 on Capital Radio's AM frequency, after the Independent Broadcasting Authority had urged stations to end simulcasting and threatened to remove one of their frequencies if simulcasting continued. The original DJs on the early incarnation of Capital Gold included Tony Blackburn, Kenny Everett and David Hamilton. The hiring of radio personalities to host networked shows continued to be a feature of the Capital Gold network as it grew.
