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.
