North 1 West is a rugby union league at the sixth level within the English league system. The league is made up of teams from the north-west of England; principally Cheshire, Greater Manchester, Lancashire and Liverpool. Promotion and relegation determine the makeup of the league each season, with the top team automatically moving into National League 3 North and the second-placed team entering into a play-off match with the second-placed team in North 1 East. Occasionally, depending on promotion and relegation, teams from either North 1 East and North 1 West may be required to compete in the opposite league to ensure that the number of teams in the east and west leagues remain at 14 teams each.
