Reigate and Redhill form a twin-town conurbation in Surrey that together represent one of the most active air conditioning markets in the county. The combination of an affluent commuter demographic, Victorian and Edwardian housing stock, and proximity to Gatwick Airport drives consistent installation demand. Here is the 2026 cost guide for both towns.
Typical Costs
| System Type | Typical Installed Cost |
|---|---|
| Single room split system | £1,200 – £2,200 |
| 2-3 room multi-split | £3,000 – £5,500 |
| Whole-house system | £5,000 – £9,000 |
| Annual service | £95 – £150 |
Reigate — Conservation Area and Victorian Properties
Reigate town centre is a conservation area and has a high proportion of Victorian and Georgian properties — particularly around Bell Street, High Street and the surrounding residential streets. These properties typically have solid brick walls requiring core drilling, and external unit positioning requires care to avoid the street elevation. Planning requirements for the conservation area are worth checking in advance for any property within the designated area — we advise on this at every site survey.
Redhill — More Modern Stock
Redhill has a higher proportion of post-war and modern housing compared to Reigate — the residential areas around Earlswood, Merstham and South Merstham have more cavity wall construction that is quicker and cheaper to install into. The commercial quarter around Redhill station has consistent office installation demand.
Gatwick Proximity — Noise Reduction
Properties in the Horley, Salfords and southern Redhill areas sit within or adjacent to Gatwick’s noise contour zones. Air conditioning enables windows to remain closed during hot weather while maintaining comfortable temperature — significantly reducing aircraft noise impact. This dual benefit (cooling and noise reduction) is a common motivation for installation in this corridor.
