. Since the 2021–22 season the promotion will be played in the Primera División RFEF. The competition for these places is reserved this season for the first three classified from each of the five groups that make up the entire Segunda B, as well as the best fourth classified that was resolved by a final score based on points per game. There being odd groups this season, the champions' route that gave a double chance of promotion to teams that were group champions is eliminated. After a season marked by the limitations derived from the COVID-19 pandemic, the RFEF decided to carry out the promotion in a format like the previous season's. It was developed through the elimination system, a single match. It took place in Extremadura, in a concentration format, and consisted of two qualifying rounds in which the matches were determined by drawing lots, pitting those who would have obtained a better classification against those who would have obtained a worse classification, avoiding, as far as possible, that they face each other two teams that would have belonged to the same group. In case of a tie there would have been overtime. If the tie persisted, the highest ranked team in the regular phase would have passed, with penalties to follow if both teams finished in the same position of their group. The four winning clubs of the second round were promoted to the Segunda División. The remaining clubs were assigned to the Primera División RFEF next season.
