Air conditioning for extensions and kitchen-diners in Godalming
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. An extension in Godalming with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Godalming, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Godalming is about 10 miles from Woking and falls within our Surrey coverage. That includes the GU7 postcode district.
Prices in Godalming
Budget around £1,745–£5,445 per space including VAT for air conditioning for extensions and kitchen-diners in and around Godalming. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Godalming up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
On a survey in Godalming the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. Surveys in Godalming cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
