Woolwich Borough Council rejoined the Kent County Amateur League in 1947, and despite their pre-war position, the club were placed in the Premier Division of the Western Section. However, after finishing second-from-bottom of the division in 1948–49, they left the league, dropping into Division Two of the South London Alliance. In 1954–55 they won the Division Two title, earning promotion to Division One. The following season saw them win Division One, resulting in promotion to the Premier Division. They went on to win the Premier Division title in six successive seasons from 1960–61 to 1965–66, also winning the Queen Mary Cup twice.
