The Premier Division featured 20 teams, the same as the previous season, after Stoke Gabriel were relegated to Division One East, and Elburton Villa were relegated to Division One West. Two new clubs joined the league:
Plymouth Argyle Reserves, promoted from Division One West.
Tiverton Town Reserves, promoted from Division One East.
Reserve sides are not eligible for promotion to Step 5.
Only Exmouth Town and Plymouth Parkway applied for promotion to Step 5.
With the news that Tiverton Town Reserves were resigning from the league for financial reasons at the end of the season, only one club would be relegated from the Premier Division. Also, as only three clubs satisfied the requirements for promotion from the feeder leagues, only two clubs were relegated from Division One level.
