BJJ Academies in United Kingdom.

The UK runs Brazilian jiu-jitsu under UKBJJA — the United Kingdom Brazilian Jiu Jitsu Association — formed in 2013 by black belts Dickie Martin, Dave Coles, and Simon Hayes, and recognized in 2021 by the Sports Councils of England, Wales, Scotland, and Northern Ireland as the official National Governing Body for BJJ. UKBJJA covers 300+ member clubs.

London is the country's competition anchor. The IBJJF runs two annual Crystal Palace events at the National Sports Centre (London International Open in February, London Spring Open in June); the 2026 dates are February 21–22 and June 13–14. The UK is also home to Polaris Pro Grappling — Europe's longest-running large-scale professional grappling event — founded in 2015 by Matthew Benyon and Ben Tong (Scramble) with Gareth Dummer and Lee Jones (Tatami Fightwear); Polaris 1 was held January 10, 2015 at St David's Hall, Cardiff.
