This page summarises the ratings for the clubs playing in Super League or in the other top British Leagues in 2019.

*The National Conference League has what appear to be relatively high team ratings. It is true that the top NCL teams are probably stronger than the lowest League1 teams. Ratings inflation is a problem with a closed pool of matches. Cup matches provide an antidote to these issues.
