The area is bounded by the South Croydon electoral ward of the London Borough of Croydon. To the west and south it is bounded by the historic Croydon parish boundary, which runs from Conduit Lane to Croham Hurst, crossing Croham Road where it becomes Croham Valley Road, then across to the railway line, crossing Selsdon Road where it becomes Upper Selsdon Road and crossing Carlton Road where it becomes Mayfield Road. Thereafter the old parish boundary roughly follows the railway south as far as the Red Deer public house, beyond which lies Purley Oaks. Curiously, Purley Oaks Primary School lies on the South Croydon side of the boundary and not in Purley Oaks.
