White Ensign

The club was formed in 1951, and is named after the British naval ensign of the same name, which is incorporated into the club's badge. They played in the Southend Borough Combination until joining Division Two of the Essex Intermediate League in 2002, going on to win the division at the first attempt, earning promotion to Division One. The season also saw them win the Capital Counties Feeder League Trophy and the league's Senior Cup. They were Division One champions the following season, as well as retaining the Senior Cup and winning the Senior Challenge Cup. In 2004–05 the club retained the league title and Senior Challenge Cup. The league was renamed the Essex Olympian League in 2005.

White Ensign won the Capital Counties Feeder League Trophy for a second time in 2005–06. The following season they were Division One champions for a third time, as well as retaining the Capital Counties Feeder Trophy. Division One was then renamed the Premier Division, and the club retained the league title in 2007–08, also winning the Essex Premier Cup. The following season saw them win the Senior Challenge Cup for a third time. However, this marked the end of their period of success and the club finished second-from-bottom of the Premier Division in 2013–14, resulting in relegation to Division One. They were Division One champions the following season and were promoted straight back to the Premier Division. At the end of the 2017–18 season the club moved up to the newly created Division One South of the Eastern Counties League.

In 2021 the club were promoted to the Essex Senior League based on their results in the abandoned 2019–20 and 2020–21 seasons.
