Risborough Rangers were formed in 1970 as a team of 12-year-olds who wanted to play competitive football and in the 1975–76 season, the previous years Under 16's entered into men's football via the Wycombe & District League. In their second season they won the 3rd Division. However, the team then folded, after which the club provided only boys' football until the Under 16's of 1979–80 also entered the Wycombe & District League. The club then won promotion in successive seasons, gaining promotion to the Ercol Senior League. During this period they also won the Berks & Bucks Junior Cup. At around the same time as entering the Ercol Senior League the club moved to 'Windsors', the former home of the defunct Hellenic League club Princes Risborough Town. Within several years, the club had managed to improve the ground by building a clubhouse/bar and extended the covered standing area.
