Within the Premiership and Championship division, clubs would be seeded into four equal groups, containing four clubs. Groups are determined through the World Athletics seeding system.
Each seeded group would have the opportunity to compete against three other divisional seeded groups through three fixtures during the season. Each fixture weekend would involve two Premiership and Championship matches of eight clubs per round.
The fourth fixture is a Grand Finale weekend which involves two separate fixtures. The top 8 clubs in the Premiership based upon the league table after the first three rounds of fixtures contest Match A and clubs from 9th to 16th contest Match B. Likewise in the Championship.
National One involves six clubs following traditional competition structure of four fixtures. Click on club names to view profiles.
