Established in 1993 by former wrestler turned promoter Andre “Sledgehammer” Baker, it is one of the National Wrestling Alliances territories. In the late 1990s, the UK Hammerlock became a member of the NWA, opening Europe to its influence.
The promotion would also branch out after the turn of the century, setting up a sister operation, known as NWA Ireland as well as gain a working relationship with the Scottish Wrestling Alliance.
Hammerlock training school graduate Fergal Devitt is their biggest success currently competing under the ring name of Prince Devitt.
Hammerlock stopped running events in 2007 and officially folded in 2009.
In June 2011 NWA UK Hammerlock officially reopened its doors with a memorial show to its late founder Andre Baker, and has several events planned in October and December, though the promotion is now running shows primarily in Essex and has not relaunched its school camps yet.
In December 2013 Hammerlock Wrestling left the NWA.
