Affiliated with the Bedfordshire County Football Association, they are currently members of the Spartan South Midlands League Premier Division and play at Creasey Park.

[2] In 1950 the club joined the Metropolitan League,[3] and in 1956–57 they reached the first round of the FA Cup for the first time, eventually losing 3–1 at Margate.

Barry Fry had become Dunstable manager towards the end of the 1973–74 season, and with chairman Keith Cheeseman providing him with blank cheques, Fry attracted several big name players to the club, most notably Jeff Astle and George Best, as well as arranging a friendly match against his former club Manchester United.

[5] Although Best only played in two friendly matches and made no competitive appearances for the club,[5] Astle stayed at the club for that season and scored 34 goals as they finished as Division One North runners-up, earning promotion to the Premier Division.

With the formation of the Conference North and South, a fifth-place finish in 2003–04 was enough for Dunstable to be promoted, although they were transferred to the Premier Division of the Southern League.

The following season saw them finish in the relegation zone, but the club were reprieved due to FA restructuring and moved to Division One Midlands.

[2] However, they were relegated back to the Spartan South Midlands League at the end of the 2008–09 season following a 13-point deduction.
