Local knowledge

Cooling a conservation-area town properly

Farnham is one of Surrey's best-preserved market towns, and that shapes every installation. The Georgian frontages of Castle Street and West Street sit within a conservation area with many listed buildings, so condenser siting — rear elevations, courtyards, screened ground positions — matters as much as the kit itself, and consent is sometimes required. Away from the centre, the family homes of Wrecclesham, Hale, Heath End and Rowledge are far more straightforward: a wall-mounted split installs in a day, and multi-splits suit larger houses toward Moor Park. The town's independent shops, studios and offices also turn to compact cooling systems that respect older buildings while keeping staff and stock comfortable through warmer summers. Warmer summers have pushed enquiries well beyond July, and heritage jobs in particular reward booking a survey early in the year rather than at the peak; you can see every area we cover on our Surrey air conditioning hub.

Farnham air conditioning FAQs

Can air conditioning be installed in Farnham's conservation area or a listed building?+

Often, yes — but with care. Much of central Farnham around Castle Street and West Street is a conservation area with many listed buildings, so condenser siting matters and listed building consent or planning permission may be required. Experienced installers will advise on discreet, compliant positions before quoting.

Which villages around Farnham do you cover?+

Wrecclesham, Rowledge, Hale, Heath End, Badshot Lea, Churt and The Bourne are all covered, along with Farnham itself. Enter your postcode and we will match you with engineers who work in your part of the town.

How much does air conditioning cost in Farnham?+

A typical single wall-mounted split costs £1,800–£2,500 supplied and installed (UK range £1,500–£3,000). Multi-splits run £2,800–£5,000 for two rooms and £4,500–£7,500 for three. Farnham, like the wider South East, sits toward the upper-middle of UK price ranges.

Will an outdoor unit spoil the look of a period Farnham home?+

It does not have to. Compact modern condensers can be sited on rear or side elevations, at ground level behind planting, or screened — and in sensitive settings that discretion is often what planning officers want to see. Your installer will walk the options with you at survey.

Outside the conservation area, do I need planning permission in Farnham?+

For most Farnham homes outside the conservation area, usually not. Since England's permitted development rules were updated on 29 May 2025, a house can normally have a single outdoor unit of up to 1.5 m³ fitted without a planning application — the old rule keeping the condenser at least a metre from the boundary has gone, and a detached home may now take up to two units. Flats are tighter, at 0.6 m³ and with freeholder consent, and the newer MCS 020a noise assessment caps sound at 37 dB at the nearest neighbour's window, which shapes siting. Inside the conservation area or on a listed building, consent is still needed; our planning-permission guide sets out the full conditions.
