Sidlesham were formed in 1921 but due to financial problems folded in the mid thirties. In 1946, the club reformed and moved to the Recreation Ground in 1950.
Over the years, many improvements were made and at Christmas 1977 the club house was opened. In 1985, after much hardwork and fundraising, Sidlesham became the first West Sussex League side to have floodlights installed.
The desire to progress led to the appointment of Joe Laidlaw, an ex Portsmouth player as manager. Joe was not the first ex pro to play for Sidlesham, in the early 80's another former Portsmouth player Dave Monks turned out.
