Air conditioning for extensions and kitchen-diners in Epsom
In Epsom, a side wall of a single-storey extension is usually the neatest place for the indoor unit. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
For a kitchen-diner in Epsom, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Epsom as part of Surrey, roughly 12 miles from Woking. Coverage includes KT17 and KT19.

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. 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.
