The league's two other cups are the Tony Kopp Cup for the Northern section of Divisions Two and Three and the Bareham Trophy for the Southern and Central sections of the same divisions.
The remaining competitions within the league are the charity cups, these operate laterally across the northern and southern section of each division.
