Air conditioning for extensions and kitchen-diners in Wantage
In Wantage, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
An extension in Wantage with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Wantage lies roughly 13 miles from Oxford, and we cover it as part of Oxfordshire. We cover OX12 and the streets around them.

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 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.
