Prices in Farnham
In South East England, our guide range for wall-mounted air conditioning is £1,395–£3,595 per room, including VAT. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £1,895–£2,595 here.

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.
