Hassocks Fatboys were formed in 2012 out of the desire to give Keymer and Hassocks Sports & Social Club a Sunday League Football team. Members were encouraged to sign up via a sheet of paper on the notice board and the squad came together in a matter of weeks before the start of the 2012-13 Sussex Sunday League season, in which we were placed in Division Five.

Alongside members, the team was recruited from outside the Club in order to fill the remaining places in the squad. The aim for the first season was to finish anywhere outside the bottom two and under the management of Daniel Lawrence, that was achieved with a respectable sixth place and a run to the quarter finals of the Vic Bettney Memorial Trophy.

2013-14 saw the club invest heavily on improving the playing side aided by the ransacking of the defunct Mooch FC for players and with a talented 23 man squad the Fatboys ended the season in second place in Division Five and beaten semi finalists in the Vic Bettney to eventual winners Westdene Wanderers.
With the brand growing at such a rate and more people wanting to pull on the famous shirt, the decision was taken to run a reserve team for 2014-15, competing in Division Five while the front side were handed a double promotion into Division Three.

Scott McCarthy took over as first team manager and led the Fatboys to the Division Three title in his first season in charge as well as the last eight of both the Sussex Sunday League Trophy and the Ron Pavey Bowl. Lawrence meanwhile was at the helm of the reserves who ensured their first season didn’t end with a bottom placed finish, a four game winning streak at the end of the campaign securing eighth spot.

2015-16 was more of a battle with both teams struggling to get 11 men out onto the pitch at times. For the first team, a fourth place finish in Division One was a remarkable achievement given the fact it took until October for them to win a game while the reserves at least showed some consistency in finishing second bottom for the second season running.

For 2016-17, the first team found themselves with an unwarranted promotion into the Premier Division of the Sussex Sunday League after a number of clubs dropped out. There were strong fears that the step up would prove to be one beyond the Fatboys and it certainly looked that way as McCarthy’s side occupied bottom spot in the league after three games having conceded 18 goals. Even as late as February they looked consigned to relegation until a remarkable haul of 10 points of a possible 15 kept them up on the final day of the season. It was an encouraging campaign for the reserves as well. Under new manager Jamie Stratton, they claimed a highest ever finish of fifth in Division Three as well as well as a best ever cup run, reaching the last eight of the Ron Pavey Bowl.
