You can get into refereering through a structured training programme run by the Football Association (FA).
The course takes up to 24 hours to complete and includes laws of the game, the role of the referee and practical skills. You must also referee at least five 11-a-side games and be assessed by your referee mentor.
You would usually start refereering at youth football level then progress as your experience grows. You can do further training with the FA to help you move on to refereering at higher levels in both the mens's and women's game.
