Air conditioning for extensions and kitchen-diners in Witney
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. For a kitchen-diner in Witney, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Witney with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Witney is about 10 miles from Oxford and falls within our Oxfordshire coverage. Coverage includes OX8, OX28 and OX29.

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
A survey in Witney 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. On a survey in Witney the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
