Mousehole joined the
Cornwall Combination in 1960–61 and were promoted to the
South West Peninsula League Division One West on its formation in 2007, after finishing as Combination runners-up the previous season. They won Division One West in
2015–16. At the end of 2018–19, the league was restructured, and Mousehole successfully applied for promotion to the Premier Division West, at Step 6 of the
National League System. In 2017, the club had a sponsorship arrangement with the Endorsed Group, a recruitment and software company run by a local businessman. Together with the club they set up the Endorsed Academy, aiming to improve coaching standards and provide opportunities for young footballers in Cornwall. Mousehole hosted a pre-season tournament in July 2018, the Endorsed Cup, featuring youth teams from
Newcastle United,
Huddersfield Town and
Bolton Wanderers. In 2018, an approach was made by Mousehole concerning a possible merger between themselves and neighbours
Penzance A.F.C., amid concerns that Trungle Parc may not prove viable as Mousehole progress through the leagues. A further approach was made by Penzance in 2019, but in May, Mousehole released a statement confirming they had withdrawn from the discussions. In 2021, they were promoted to the Premier Division of the
Western League based on their results in the abandoned
2019–20 and
2020–21 seasons. They were promoted to the
Southern Football League as champions in the
2022–23 season, only the second Cornish side to reach step four of the non-league system. == Records ==
