Guildford air conditioning installations reflect the town’s mix of properties — from Georgian townhouses in the conservation area around the High Street and Chertsey Street, to modern office developments at Slyfield and Ladymead, to the University of Surrey campus, to the large detached houses of Merrow, Burpham and Park Barn.

Guildford Conservation Area and Listed Buildings
Guildford town centre is a conservation area of significant historical importance. The High Street, Quarry Street, Chertsey Street and surrounding streets contain a high concentration of listed buildings dating from the medieval period through to the Georgian era. External air conditioning equipment on these properties requires listed building consent and careful positioning to satisfy both the planning authority and the technical requirements of the installation.
We have installed in listed properties in Guildford town centre — including professional offices on Chertsey Street and residential properties on Quarry Street — and understand the requirements. Pre-application discussions with Guildford Borough Council typically take 4-6 weeks but are usually positive for well-considered installations positioned away from principal street elevations.
University of Surrey Area
The area around the University of Surrey campus — Stoughton Road, Woodbridge Road and the surrounding streets — has a large proportion of HMOs and buy-to-let properties. Landlords in this area increasingly specify air conditioning for student lets, particularly in rooms that face south or west and can become very warm in summer. Installations for rental properties benefit from our end-of-tenancy documentation service and landlord account pricing for multiple installations.
