In 1977 the club were elected to the Athenian League and were twice runners-up before the league folded in 1984.
We competed in the London Spartan League in 1984/85 winning both the Premier Division title and the League Cup.
The summer of 1985 bought about the amalgamation of the football club with Hillingdon Borough FC who had lost their ground and were about to fold.
We played in the Southern League as Burnham & Hillingdon FC but reverted back to the former name of Burnham FC in 1987. Season 1994/95 saw us finish bottom, resulting in relegation to the Hellenic League.
After 3 seasons in the Hellenic League finishing fifth, third and again third in 1998/99 the club won both the Premier Division title and the League Cup, thus gaining promotion back to the Southern Football League where we have played since.
Season 2006/07 saw the club achieve their highest league position, finishing 3rd, thus qualifying for the end of season Promotion Play-Off semi final, unfortunately losing to the eventual winners Swindon Supermarine.
