[1] A play-off between the winners of each conference determines the overall league champion, who is promoted to the Adran Premier.
Similarly, the winners of the North Wales Women’s League and the South Wales Women's & Girls' League are promoted into Adran North and Adran South, respectively, replacing the lowest-ranked team or filling a vacancy in the table.
In 2021–22, Abergavenny Women won the Adran South conference and promotion to the Premier League.
Neither of the top two teams in Adran North had applied for a Tier One license, so there was no play-off match.
Abergavenny were relegated to Adran North after losing the Premier league, but had been unable to field a team for two games that season and folded rather than returning to the second tier.
