The club became founder members of the Greater London League, and were placed in the "A" section. A seventh-place finish in 1964–65 was enough to earn a place in the Premier Division the following season. In 1966–67 they won the league, before joining the Metropolitan League in 1969. They won the league in 1970–71, but at the end of the season the league merged into the Metropolitan–London League, which Epping won at the first attempt. The following season they were runners-up, before winning a second title in 1973–74.
