Warner Music UK is a division of the Warner Music Group, constituted as a holding company in 1991. It was previously incorporated as WEA Records Ltd. Its subsidiaries consist of Warner Bros Records UK (also known as WEA Records UK Ltd), East West Records, Atlantic Records and its subsidiary Asylum Records UK, Rhino UK (formed in 2010 to manage reissues and compilation releases) and its subsidiaries A&E Records (also known as Mushroom Records UK), London Records and 679 Recordings, and 14th Floor Recordings.

Warner Music Group acquired the post-1979 London Records back catalogue, along with the London name and brand identity, when label head Roger Ames left Polygram in 1998. Warner Music Group gave control of the London Records roster to Warner Music UK.

The London Records label name was used by Warner Music UK for the UK-based artists acquired from Polygram, including artists who recorded with the independent record label Factory Records, in particular Happy Mondays and New Order.

Warner Music UK’s subsidiary Warner Records 90 reissued most of the post-1979 London Records artist roster plus a few titles from Warner Music’s ownership of the London Records label from 1998 onwards.

Independent label Because Music acquired Warner Records 90 from Warner Music UK in 2017. The New Order back catalogue, acquired by London Records from Factory Records, was retained by Warner Music UK. At the same time, Warner Music UK acquired the Factory Records brand identity. Reissues from the New Order catalogue since 2017 are sometimes branded as Factory Records releases.
