The club was established in 1976 and initially played in the Hounslow & District League.[2] They later transferred to the West Middlesex League before joining the Middlesex County League in 1984.[2][3] League restructuring in 1991 saw Division One reduced from 22 to 12 clubs and renamed the Premier Division, with Hanworth relegated to the renamed Division One.[3] However, a third-place finish in 1991–92 saw them promoted to the Premier Division.[3] In 1993–94 the club were relegated to Division One despite finishing eighth. The following season they finished third in Division One, earning another immediate promotion back to the Premier Division.[3]
In 2002–03 Hanworth were Premier Division champions,[4] also winning the Premier Division Cup with a 3–1 against Stonewall in the final.[5] They were champions again in 2004–05,[4] after which they were promoted to Division One of the Combined Counties League.[6] They won the Division One Challenge Cup in 2006–07 and retained it the following season which also saw them end the season as Division One runners-up.[7] However, they were denied promotion due to their ground failing to meet the necessary criteria.[8] After completing the work during the 2008–09 season, they were promoted at the end of the season after finishing as runners-up again.[6]
In 2011–12 Hanworth won the Southern Combination Challenge Cup and retained the trophy the following season. In 2013–14 they won the Southern Combination Challenge Cup for a second time, as well as winning the Combined Counties League Premier Challenge Cup, beating Spelthorne Sports in the final.[7] The 2015–16 season saw them win the Middlesex Charity Cup for the first time, beating Cockfosters 2–0 in the final.[9] They won the cup again in 2017–18 with a 3–2 win over Spelthorne Sports in the final.
