[1] With a view to a merger between the South West Peninsula League and the Western League in 2023–24, four clubs were to be automatically promoted from each division to Step 5, depending on ground grading.
The fifth-placed clubs may also have been promoted, on a PPG (points per game) basis.
[2] However, the FA scrapped the merger in February 2023 after a breakdown in negotiations, and promotion was reverted to one club per division.
[3] Premier Division East featured 19 teams, reduced from 20 the previous season, after Torpoint Athletic were promoted to the Western League Premier Division; Stoke Gabriel & Torbay Police were relegated and Ottery St Mary resigned from the league.
St Dennis had initially been relegated from the league, but were reprieved due to a resignation elsewhere in the pyramid.
