In 2006–07 Lewes reached the first round of the FA Cup again, losing 4–1 at home to Darlington. The following season saw another first round appearance, ending in a 3–0 defeat at Mansfield Town. After winning the Conference South title at the end of the season, the club were promoted to the Conference National, having carried out works on the Dripping Pan. However, after winning the title, manager Steve King and all-but-one of the first team squad left the club. The following season saw them finish bottom of the Conference National, resulting in relegation back to the Conference South.
