Air conditioning for extensions and kitchen-diners in Didcot
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In Didcot, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Didcot, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Didcot sits around 10 miles from Oxford, inside our Oxfordshire area. Coverage includes OX11.

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
For most houses in Didcot, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
A survey in Didcot 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. We book surveys in Didcot at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
