Bedroom and loft air conditioning in Walton-on-Thames
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. Top-floor flats in Walton-on-Thames feel the heat most, because the roof sits right above the bedroom.
For bedrooms in Walton-on-Thames, we place the outdoor unit at the back of the house, away from neighbours' windows. Walton-on-Thames lies roughly 8 miles from Woking, and we cover it as part of Surrey. Postcode districts we cover here include KT12.

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
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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
