I mean, even though they're not explicitly connected, Guy Ritchie has made a number of movies with similar tone/vibe and London Crime setting. I'm choosing to believe they're happening in the same universe
Lock, Stock and a smoking barrel
Snatch
Revolver
The gentlemen (which was also derived as a decent Netflix show)
There's also Layer Cake from Matthew Vaughn which scratches the same itch.
If you like it you should check out Guy Ritchie's previous film, 2005's Revolver. It's a little more "experimental" I'd say, but some of the film's choices are really cool, especially how it depicts how some characters remember and interpret events differently than others.
