Sudbury were moved into the Southern League Division One Midlands for 2008–09 following a restructuring of the English football pyramid. After two seasons of mid-table finishes the club was moved back to the Isthmian League Division One North for 2010–11. Smith resigned in September 2011 and was replaced by his assistant Chris Tracey. At the start of the 2013–14, Sudbury appointed Wroxham manager David Batch as their new manager, after Chris Tracey left the club. Sudbury reached the final of the Isthmian League Cup in April 2014, but lost 3–0 away to Maidstone United. Batch left to join St Neots Town at the end of 2014, and was replaced by Jamie Godbold. Godbold led the club to a third-place finish and qualification for the play-offs, where they were defeated by Brentwood Town in the semi-final. The following season Sudbury won the division with three games to spare, earning promotion to the Premier Division. Their stay in the division only lasted one season as they were relegated back to Division One North at the end of the campaign, the club's first-ever relegation. Mark Morsley re-joined as first team manager in early 2017–18.
