From 2018 to 2022, the league consisted of three divisions at Tiers 6 to 8. The 2018 league was essentially a continuation of a two division system which operated from 2003. It was split into two geographical sections at Tier 7 from 2011, with the lower (Tier 8) Division Two disbanded two years later. After five seasons of that setup, a three-division model was restored. The league currently consists of two divisions, a Premier League and a Championship.
Member clubs for the 2024–25 season
The current system sees two clubs automatically relegated from the Premier League, who are replaced by two clubs from the Championship. The third-bottom club in the Premier League enters a play-off with the clubs who finish between third and fifth in the Championship. In the semi-finals, the Premier League side plays the fifth-placed Championship side, and the fourth and fifth-placed teams play each other, both games over two legs. The winners then progress to a single-leg final.
^Using a 'points per game' algorithm applied in other leagues, Banks o' Dee (who were leading the table by a big margin) would have been nominal champions.
