The club was established as Beaconsfield SYCOB in 1994 by a merger of Beaconsfield United of the
Spartan League and Slough Youth Club Old Boys of the
Chiltonian League, with the new club taking Beaconsfield United's place in the Premier Division of the Spartan League; Beaconsfield United had played in the Spartan League since 1979 and won the Senior Division in 1982–83, earning promotion to the Premier Division, whilst Slough Youth Club Old Boys had been members of the Chiltonian League since 1990. When the league merged with the
South Midlands League to form the
Spartan South Midlands League in 1997, Beaconsfield were placed in the Premier South Division, finishing as runners-up in the league's
first season and earning a place in the Premier Division for the following season. In
2000–01 Beaconsfield won the Premier Division. The
2017–18 season saw them win the renamed East Division, earning promotion to the Premier Division South. In
2023–24 Beaconsfield finished fourth-from-bottom of the Premier Division South and were relegated to Division One South. ==Club staff==
