On VFV side, Merelbeke and Tienen decided not to play a championship match. There was also no match between the overall VFV and ACFF champions.

Promotion play-offs
Promotion play-offs VFV
The teams finishing in second place in the Third Amateur Division A and Third Amateur Division B will take part in a promotion playoff first round together with three period winners from both divisions. These 8 teams from the VFV will play the first round of a promotion-playoff, with two teams promoting to the 2019–20 Belgian Second Amateur Division. Depending on the number of VFV teams relegating from the 2018–19 Belgian First Amateur Division and possible mergers and bankruptcies, more teams might get promoted.
In Division A, Wetteren (2nd place overall) and Zwevezele (won two periods) qualified directly, while Pepingen-Halle and Wingene were awarded a place based on their league finish. In a similar fashion in Division B, Houtvenne (2nd place overall) and Lyra-Lierse (won one period) were joined by Sint-Lenaarts and Betekom.
