Until 2016, the club also operated an association football team who played in the Gibraltar Premier Division until its relegation and resignation at the end of the 2015–16 season.

However, his resignation in early 2016, coupled with the departure of key players, saw them plummet down the league and finish in 9th, meaning they had to participate in a play-off to determine their fate.

Britannia returned to football in 2023, joining the Veterans ShieldPlay League for retired players.

Britannia launched their futsal team in 2015, however, after resigning from the football league, the club remained inactive for a year.
