Ducted air conditioning in Warminster
Ducted systems suit Warminster loft conversions and new extensions where ceilings are being boarded anyway. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
For a renovation in Warminster, the best time to plan ducted cooling is before the plasterers arrive. Warminster sits around 30 miles from Swindon, inside our Wiltshire area. Homes in BA12 are all within our coverage.

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
Surveys in Warminster cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Warminster 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.
