2012–13 B Group

Movement between A PFG and B PFG

The champions of the two groups of B PFG were promoted to the A PFG. These were Pirin (Gotse Delchev) (West B PFG champions) and Etar (Veliko Tarnovo) (East B PFG champions) . The third promoted team is Botev (Plovdiv), which won the promotion play-off against Sportist (Svoge).

Vidima-Rakovski, Kaliakra and Svetkavitsa were relegated after finishing in the bottom three places of the table at the end of season 2011/12.

Movement between B PFG and V AFG

During the winter break Dorostol (Silistra) and Chavdar (Byala Slatina) decided to cancel their participation on the East B PFG and West B PFG and relegated. Additionally the teams of Dobrudzha (Dobrich) and Nesebar (from East B PFG) and Slivnishki Geroi and Malesh (Mikrevo) (from West B PFG) relegated after finishing on 9th and 10th place. Additionally the teams of Chernomorets (Pomorie) and Akademik (Sofia) did not receive a professional license from the BFU and were relegated to V AFG.

On the place of those six teams came the V AFG champions Rakovski 2011 (South-East), Shumen 2010 (North-East), Pirin (Razlog) (South-West) and Spartak 1919 (Pleven) (North-West).

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. Five days later Sportist Svoge also filed an application for exclusion from B Grupa. 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.

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. 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. 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.

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. 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.
