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. 

In 2015/16 due to crippling debts the club had to take a new direction with new management and committee, thanks to many local clubs and a massive fundraising effort by the local community and our hardworking volunteers the club was saved and has gone from strength to strength.

In 2017–18, Millbrook were crowned Division One West champions, earning promotion to the SWPL Premier Division. At this point the club re installed new floodlights and conducted several ground upgrades to allow us to play at Step 6,  Following league reorganisation at the end of the 2018–19 season, the club were placed in the SWPL Premier Division East a move that wasn’t a club decision however we have embraced it and moved forward whilst enjoying a new challenge.

As part of the clubs progression we played in the extra prelim round of the FA Cup for the first time in 2020 and after an unbelievable run reached the 3rd round proper of the FA Vase.

In 2021 after the FA conducted a re structure of steps 3-6 we were promoted to Step 5 of the National league system and for the first time in the clubs history the Premier Division of the Western League based on our results from the abandoned 2019–20 and 2020-21 seasons.
