Air conditioning for extensions and kitchen-diners across Bristol
In Bristol, a side wall of a single-storey extension is usually the neatest place for the indoor unit. An extension in Bristol with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

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 Bristol, 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
Surveys in Bristol cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Bristol at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
