[2] Starting this season, the Premier Division (Step 5) in the league promotes two clubs; one as champions and one via a four-team play-off.
This replaced the previous inter-step play-off system.
Promotion from this division depended on ground grading as well as league position.
The 2023–24 SCFL Peter Bentley Challenge Cup saw Newhaven enter the competition as defending champions, having defeated Crowborough Athletic in the previous season's final.
