Earlswood is a suburb of Redhill in Surrey, England forming the south of the town of Redhill, and part of its RH1 postcode district. Earlswood lies on the A23 between Redhill (in the direction of London) and Horley (next to Gatwick Airport), from which the neighbouring community, Whitebushes is separated by a wide rural buffer zone. The two main southern communities of Redhill are in local administration grouped together to form a ward, Earlswood and Whitebushes. Earlswood Common is a Local Nature Reserve that separates the suburb from the southern suburbs of Reigate, and has two lakes known as Earlswood Lakes, picnic areas and a golf course. South Earlswood is contiguous with Whitebushes but is also to the west. East of its station and the Brighton Main Line are three unconnected estates: east Earlswood; Royal Earlswood Park and East Surrey Hospital with Whitebushes.
