On 15 June[when?] the Executive Committee of Bulgarian Football Union decided to reduce further the number of teams due licensing problems in most of the clubs and reuniting the teams into one league. The new format will consist of 14 teams, playing twice against each other, once home and once away. A group of 16 teams was intended at first, but two teams decided to drop off the competition before the start of the season.
In contrast to the previous season, there was no 'promotion play-off', a decision made by the BFU to reduce the number of teams at A PFG. Instead, there were just two teams, promoting to A PFG, and 4 teams relegating from to the top league.
On 20 July 2012 Bdin (Vidin) canceled their participation from B PFG because of unpaid debts and unsatisfactory financial planning, which would not allow the club to survive throughout the season. This left the league with 15 teams only.[1] Five days later Sportist Svoge also filed an application for exclusion from B Grupa.[2] On 2 August the BFU confirmed that 14 teams will start the new season, with Bdin and Sportist excluded. The first games took place on 19 August.[3]
Winter break
On 15 February the owners of Spartak Pleven announced they were going to cancel the club's participation in the championship within the next three days due to financial difficulties. All remaining fixtures were to be awarded 0–3 against them.[4] On 21 February a new sponsor began talks to take over the club, as representatives paid the players and staff their outstanding salaries. The decision to suspend the team's participation in the 2012/13 season was overturned until the deal is finalized.[5] On the next day a group of around 20 fans held a protest in front of the local municipality, demanding that the city takes action to help their team.[6]
On 26 February the BFU announced it was suspending OFC Sliven 2000 due to their inability to field at least 7 players in their senior team. Due to this, the club's first spring game on 2 March at home to FC Bansko was cancelled, and the rest of their season was placed under question.[7] The Football Union confirmed its decision in a statement released on 7 March, while also cancelling Sliven's second game against Spartak (Varna) and awarding them a 3–0 win. Four days later the BFU suspended OFC Sliven 2000 from the 2012–13 B PFG due to the club's failure to appear in two consecutive games.[8]
^Sliven were expelled from B PFG because they did not have a squad of minimum 7 players for the beginning of the spring games. All remaining fixtures are awarded 0–3 against them and they received a 3-point deduction.[9]
