Air conditioning for extensions and kitchen-diners in Clifton
In Clifton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
An extension in Clifton with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Clifton sits within our Bristol area. That includes the BS8 postcode district.

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 Clifton, 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
We book surveys in Clifton at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
