Dorking — Surrey Hills Conservation
Dorking sits at the foot of the North Downs in the Surrey Hills AONB. The town centre is a conservation area with a high proportion of Victorian and Georgian buildings — South Street and West Street are among the most characterful retail streets in Surrey. Properties in the conservation area require careful consideration of outdoor unit positioning. The surrounding countryside has numerous large rural properties and converted farm buildings that represent the premium domestic installation market.
Leatherhead — Business Quarter and Rural Surroundings
Leatherhead has a significant commercial and pharmaceutical research presence — the Randalls Road and Fetcham Park business areas house major employers including Novartis and other pharmaceutical companies. Commercial air conditioning demand from this sector is consistent. The residential market around Fetcham, Ashtead and Great Bookham has substantial detached housing with above-average property values.
Rural Properties Around Both Towns
The Surrey Hills countryside around Dorking — Westcott, Mickleham, Box Hill, Holmbury St Mary — has a high density of premium rural properties: large country houses, converted barns and farmhouses that represent the top end of the residential installation market. Multi-room installations in these properties often use premium brand specifications with concealed pipework and careful unit positioning to maintain the rural aesthetic.
