Multi-split air conditioning in Farnham
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. In a house in Farnham with a usable loft, multi-split pipes can often run through it so the front stays clear.
Twin and triple systems suit Farnham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Our Surrey coverage takes in Farnham, about 13 miles from Woking. Postcode districts we cover here include GU9.
Prices in Farnham
Our South East England guide price for multi-split air conditioning is £2,995–£9,445 for 2–4 rooms, VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Triple option in Farnham (three rooms with mixed indoor styles and Wi-Fi control throughout) usually comes to about £4,095–£6,645.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. A survey in Farnham usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
