The Professional Development League is the sixth campaign of post-EPPP Under-23 football's second tier, designed for those academies with Category 2 status. A total of 21 teams are split regionally into north and south divisions, with each team facing opponents in their own region twice both home and away and opponents in the other region once for a total of 30 games each in the North Division, and 29 games in the South division.
At the end of the season, the teams finishing in the top two positions of both divisions will meet in the knockout stage to determine the overall league champion.
Burnley U23s were officially granted Category Two status in the summer of 2017 and became the league's 21st team.
