In 2020, Gangs of London was adapted into a television series by Gareth Evans and Matt Flannery. In an interview with Sky News about the show, Evans revealed that he was originally hired to make a film franchise based on the game, but felt that if they went this route then they would have "two-thirds of our running time focused purely on our central characters, and then only a third left to explore the side characters that populate that world". Feeling this wouldn't be able to do justice to the diverse cultures and ethnicities that make up London, Evans proposed making it a TV show instead because "you can afford to go off and detour for 10 to 15 minutes and spend time with other characters, and learn about them in more detail."
