In 1926–27 the club were Redhill & District League champions, and in 1929–30 they won the East Surrey Junior Cup. Merstham won back-to-back titles in 1934–35 and 1935–36 and again in 1949–50 and 1950–51, after which they moved up to the Surrey Intermediate League, going on to win the league at the first attempt. In 1965 the club moved up to the Surrey Senior League. They were champions in 1971–72, but left the league in 1978 to join the London Spartan League, largely composed of clubs to the north of London. Their first season in the league saw them win its Challenge Cup and the Surrey Senior Charity Cup, before winning the East Surrey Charities Cup in 1979–80.
