Ground
The club play at the Elms Recreation Ground, which is shared with the town's cricket club. Following their Hellenic League title win in 2004–05, two separate seated stands were built on one touchline, with the existing seated stand removed and replaced by a covered standing area. As the ground is shared with the cricket club one side of the pitch is fenced off during the football season. Both ends of the pitch have uncovered hardstanding. Floodlights were installed and inaugurated with a friendly match against QPR in July 1994, at which the club's record attendance of 2,000 was set. The ground currently has a capacity of 2,000, of which 150 is seated and 250 covered.
