After finishing bottom of Division One West in 2008–09 and second-from-bottom in 2009–10, financial problems forced Millbrook to resign from the league, with the first team taking over from the reserves in Division One of the East Cornwall League. The club were Division One runners-up in 2012–13, earning promotion to the Premier Division. A third-place finish in the Premier Division in 2013–14, a season that also saw them lose the League Cup final, was enough to secure promotion back to Division One West of the South West Peninsula League.
