The championship was planned to be held with 20 teams in one group, but with the statement of Asteras Tripolis B, the teams became 21 and so it was decided that the championship would again be held in two groups, one group with 10 teams and another with 11 teams. The
B Teams of
PAOK and
AEK Athens also compete in the league for a fourth consecutive year, while the ones of
Olympiacos and
Panathinaikos were dissolved, since they were relegated to
Gamma Ethniki, which is an amateur division and cannot compete there. Also taking part in this year's league for the first time, is the
B Team of
Asteras Tripolis, which was founded for this purpose. Later on 26 August 2024,
Ionikos withdrew from the championship due to financial and management problems, after having initially declared participation in the league. Thus the number of teams reduced again to 20.
Way of Conduct The championship was played in two phases. In the first phase in each group, each team faced all opponents twice (home and away, a total of 18 matches in both Groups). The second phase included ranking matches (play off and play out) for the first place in the group and Promotion to
Super League 1, and for the relegation of four teams, those who occupied positions 9 to 10 on both Groups. In the play offs, the first five teams in the first phase's standings participated, and they competed twice with the rest, at home and away. They included 10 matchdays and 8 matches for each team. In the play offs, the teams entered with half of the points they won in the first phase. The teams that took the positions 6th to 10th in the regular season on both Groups, participated in the play outs. As in the play offs, the teams started with half of the points they had collected in the first phase and competed with the rest in double matches home and away (8 matches for each team in both Groups). The teams occupied the last two positions in Group A and Group B in the play outs were relegated to
Gamma Ethniki.
Promotion and Relegation A total of two teams were promoted to Super League 1, the winners of the play offs of each group and a total of 4 teams were relegated to the
Gamma Ethniki. ==Team changes==
