[1] The league had two divisions, although Division Two consisted mainly of the reserve teams of clubs in Division One; Medway Corinthians and Orpington Athletic were the only two clubs to field a first team in Division Two; Medway joined in 1959 and left in 1961, with Orpington joining in 1960 and remaining until the league folded.

In 1964 after only five seasons of existence, it merged with the London League to form the Greater London League.

Fourteen clubs joined the league for its first season: Ford United won the League Cup in the 1960–61 season.

Whistable Town rejoined the league for the 1963–64 season.

At the end of the season most clubs joined the newly formed Greater London League.
