The club began its new chapter in the Hertford and District League, starting out in Division Two. Promotion came in the first season and was followed by the Division One title and a League Cup Final appearance. Two seasons in the premier Division, finishing fourth and then third, prompted a move to the Herts Senior County League.

Following three seasons in the top flight of the County League, Knebworth were relegated to Division One at the end of the 2008–09 season.
