After being reformed in 1929, Romford entered a reserve team into Division One of the London League. During their time in the Athenian and Isthmian leagues the reserves played in the reserves sections of the leagues. When the club turned professional in 1959 they entered the reserves into the Eastern Counties League, where they spent four seasons before joining the Metropolitan League in 1963. They went on to play in the Eastern Professional Football League, which they won in 1967–68, and the Essex Senior League, where they had a single season in 1974–75.
