Air conditioning for extensions and kitchen-diners in Barnstaple
South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much. An extension in Barnstaple with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Barnstaple, a side wall of a single-storey extension is usually the neatest place for the indoor unit. We cover Barnstaple as part of Devon, roughly 49 miles from Plymouth. We cover EX31 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
For most houses in Barnstaple, 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
On a survey in Barnstaple 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. We book surveys in Barnstaple at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
