Multi-split air conditioning in Bath
In a house in Bath with a usable loft, multi-split pipes can often run through it so the front stays clear. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
Twin and triple systems suit Bath homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Bath sits around 41 miles from Taunton, inside our Somerset area. That includes the BA1 postcode district.
Prices in Bath
Guide prices around Bath run from £2,450 to £7,750 for 2–4 rooms including VAT. That is close to the UK middle for this kind of work.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
On a survey in Bath 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 Bath at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
