Tormarton FC originally formed in 2012 under the name of Cesson FC. After two seasons in 2014, the club was renamed Tormarton FC. 

In the 2016-17 season the club won the GFA Intermediate Cup. 

The club founded its first ever reserve team in the 2021/2022 season with Tom Ashton running the team as manager. The reserves finished 10th in their inaugural season in the Bristol and District League (Division 5). At the end of the season Tom Ashton stepped down Reserve Team Manager due to personal reasons. 

For the 2022/2023 season, the club reverted back to having one team with an aim to push on and have a strong season with a singular strong squad. 

In the 2024/2025 season, the club re-introduced the reserve team in Division 4 of the Bristol and District leagues. In November 2024, first team manager Sam Jarman left the role as First Team manager after 5 years in the role and Reserve Team manager Owen Batchan was promoted to First Team manager.
