Old walls, new summers

Dorking's charm is its age — and its cooling challenge is the same thing. The brick and flint cottages around the town centre and the antiques quarter of West Street were never designed for 30-degree weeks, yet their solid walls make retrofit ductwork impractical; a wall-mounted split with neatly boxed, surface-run pipework is the pragmatic answer, sited discreetly where conservation-area rules apply. The Victorian villas toward Pixham and the family homes of North Holmwood take singles or multi-splits, while cafes, galleries and shops in the centre use compact systems to keep customers browsing on warm afternoons. Surrounding villages — Westcott, Brockham, Mickleham — fall inside the same engineers' patch. The engineers we match now fit reversible R32 systems as standard, so the same wall unit that cools a Dorking room in a heatwave also heats it efficiently through the winter at a seasonal COP of around 3.5–4 — which increasingly makes the decision about year-round comfort and running costs rather than a few hot weeks.

Dorking air conditioning questions

Yes — wall-mounted splits do not depend on cavity walls or ductwork, which makes them well suited to Dorking's older brick and flint cottages. Pipework is surface-run and boxed neatly, and the outdoor unit sited discreetly. Conservation-area addresses may need consent, which your installer will confirm.

Expect £1,800–£2,500 for a typical single wall-mounted split installed (UK range £1,500–£3,000) and £2,800–£5,000 for a two-room multi-split. Dorking, like the rest of Surrey, sits toward the upper-middle of national price ranges.
Yes — hospitality and retail premises along the High Street and West Street can be matched with commercial engineers for free. Light-commercial wall or cassette systems are common; larger VRF systems price at roughly £350–£600 per kW installed.
For most houses in Dorking the outdoor unit is permitted development under the rules England relaxed on 29 May 2025: the size limit rose to 1.5m³, the old one-metre-from-the-boundary requirement was dropped, and a detached home can now have up to two units, used for cooling as well as heating. The install must still meet the MCS 020(a) noise condition — broadly 37 dB(A) at a neighbour's window. The exceptions that matter locally are the town-centre conservation area, listed cottages and flats, which usually still need a planning application. Our planning permission guide sets out the current rules in full.
Running cost follows the electricity price, not your postcode. At the July–September 2026 price cap of about 26p per kWh — the level behind the £1,663 typical annual bill — a 2.5kW bedroom split draws roughly 18–23p an hour on cooling. Because modern R32 units are reversible, the same system heats efficiently in winter at a seasonal COP of around 3.5–4, often undercutting plug-in electric heaters. Sizing the unit correctly to the room is the biggest single lever on running costs, so a proper survey matters more than the headline price.
