The club was formed in 1920 by a group of natives of
Newcastle-upon-Tyne who were working in the Hanwell area, who adopted the famous black and white stripes of
Newcastle United as their colours. They played in the
London League during the 1920s but dropped down to more local leagues after World War II, where they remained for over twenty years. In 1970, the club made the step up to the
Middlesex County League and by the early 80s were playing in the
London Spartan League. In 1983–84, they were Senior Division champions and were promoted to the Premier Division. During their time in the London Spartan league premier Division, the club reached the final of the
London Senior Cup three consecutive seasons (1991–92 to 1993–94) winning it twice. It was also in this period that the club made their debut in the
FA Cup in the 1988–89 season, making it to the Second Qualifying round, losing to
Wembley 1–0 at home. When the league amalgamated with the
South Midlands League in 1998, Hanwell were placed in the Premier Division South but after the league's initial transitional season, a reorganisation saw them moved down into the Senior Division. They immediately won promotion back to the Premier Division where they remained until reorganisation of the non-league system in 2006 saw them placed in the new Southern League Division One South and West. The club were then jointly managed by former player Keith Rowlands (the club's leading scorer) and Boysie Wise who succeeded Chris Boothe in May 2008. The club finished in 21st place but was saved from relegation because no club came down from Step 4 of the football pyramid to the
Spartan South Midlands League. Williams left the club at the end of the season and was succeeded by former manager Ray Duffy, returning for his second spell in charge. Duffy, with the assistance of his four sons and nephew playing in the team led the club to a sixth-place finish in his first season back. In 2014 they won the Spartan League Premier Division title by 14 points, going the whole season losing just one league game and were promoted back to the Southern League for the first time since 2006–07. In their first season back at this level, Hanwell finished in 7th place, the highest position the club has been in the football pyramid, while the club were also runners up in the
Middlesex Senior Cup having lost 1–0 in the final to
Harrow Borough. Ray Duffy and coach Mark Adams stood down at the end of the season being replaced by Phil Granville, assisted by Dave Tilbury who arrived from
Harefield United. In November 2015, despite leading Hanwell Town to the third qualifying round of the
FA Cup - the furthest the club have ever been, manager Phil Granville and assistant Dave Tilbury parted company with Hanwell after just six months in charge with the club in 18th place. On 30 November 2015, returning to the side just a few months after leaving was Ray Duffy for a third spell as manager, assisted by Mark Adams. The second half of the season proved difficult leaving the club third from bottom going into the last week of the season, but after two victories Hanwell finished 20th on 39 points. At the end of the
2017–18 season, as a result of structural changes by the FA to Step 4 of the non-league pyramid, the club was moved laterally to the Isthmian League, South Central Division. At the end of the
2021–22 season, Hanwell were promoted after beating
Chertsey Town 3–2 after extra time to win the Isthmian South Central Division play-off final. It means Hanwell will play Step 3 football for the first time in their history, with the team placed in the
2022–23 Southern Premier Division South. In May 2022, joint-manager Wayne Carter left Hanwell to take up the manager's position at Isthmian South Central side Chertsey Town - leaving
Chris Moore in sole charge. ==Ground==
