The club currently compete in the Isthmian League North Division, the eighth tier of English football, and play their home matches at Thames Road.

The 1978–79 season saw Concord Rangers become the inaugural winners of the Essex Sunday Junior Trophy, defeating Bishop's Park 4–0 in a game played at Tiptree United.

[4] Concord spent 17 seasons in the Senior League, winning the title three times in that period (1997–98, 2003–04, 2007–08), Antony Smith took over the reigns in 1999 and his most important decision in the coming years was appointing Danny Cowley as Manager.

[5] The "Beach Boys" reached the play-off final in their first season (2008–09) in the Isthmian League Division One North, but lost 5–4 on penalties to Waltham Abbey.

[10] The Beach Boys were also winners of the Isthmian League Cup for 2012–13, with a 3–2 victory after extra time over Dulwich Hamlet at Maidstone United's Gallagher Stadium.

[11] 2013–14 saw Concord have a successful inaugural season at Conference South level, finishing in ninth position,[4] and also winning their first ever Essex Senior Cup, defeating higher-ranked opposition Braintree Town 2–1 at Dagenham & Redbridge's Victoria Road ground.

[22] This Essex Senior Cup win meant Flanagan joined only a small group of people who have lifted the trophy as both a player and manager; having also won the competition with Billericay Town in the 2010–11 season.

[24] Under Flanagan's reign, the side finished 10th, 18th, and 17th in the National League South, and reached the FA Cup 4th qualifying round in 2017-18, eventually bowing out to higher-division opposition Woking in a replay.
