Name changes

 * TOT-CAT were renamed TOT S.C. after an ownership dispute.
 * Rajnavy Rayong were renamed Siam Navy after an ownership dispute.

Stadium changes

 * Both Pattaya United and Siam Navy moved into the IPE Stadium in Chonburi. Pattaya's previous ground Nongprue Municipality Football Field is under renovation and Siam Navy left the Rayong Stadium as they withdrew from the province during their ownership dispute. Both teams use the same stadium even though this is actually against the league regulations. Siam Navy were to move back to Rayong and use the Sattahip Navy Stadium for the 2nd leg of the season.
 * TOT continued to use Muangthong United's Yamaha Stadium for the opening half of the season before their return to the TOT Stadium Chaeng Watthana for the 2nd leg. TOT also used the Thai Army Sports Stadium for one game in the first leg of the season.
 * Chonburi moved to the ODB Chonburi Stadium whilst a new ground is built in Bang San.
 * Sriracha's Princess Sirindhorn Stadium will be known as the Suzuki Stadium due to sponsorship reasons.
 * BEC Tero Sasana presumably have made the Thephasadin Stadium as their new home, using it for the second season running after their previous home Nong Chok Stadium was apparently being renovated. The move has also brought a bigger fan base to the club.
 * Chonburi used one of their former grounds, the IPE Stadium for two games after being suspended from using their home ground due to fan violence. Chonburi fans were also subjected to be banned from the stadium.
 * Bangkok Glass used the Thephasadin Stadium and the Yamaha Stadium for their home matches with Samut Songkhram and Pattaya United due to the Leo Stadium being unavailable during the 2011 Thai Flood's.
 * Police United used the Suphanburi Municipality Stadium and the Khao Plong Stadium in Chainat for their home matches with Pattaya United, Bangkok Glass, Khon Kaen (all Suphanburi Municipality Stadium) and Muangthong United (Khao Plong Stadium) due to the Thammasat Stadium being unavailable during the 2011 Thai Flood's.
