It was announced at the end of the season that the TPL would increase the number of teams for the start of the 2011 Thai Premier League season.

Therefore, at the end of season the three teams in the Thai Premier League that finished the season in the bottom three places (14th, 15th and 16th) would face the fourth, fifth and sixth teams from Division One in a promotion/relegation series.

They will meet each other in their group on a home-and-away basis with the winner of each group earning spots in the top flight next season.

It was also announced somewhat belatedly that the teams that finished in the bottom four places, who would normally be relegated would play in an end of season promotion/relegation series against the teams coming 3rd and 4th in the 2010 Regional League Division 2 championship stage.
