Ducted air conditioning across Somerset
For a renovation in Taunton, the best time to plan ducted cooling is before the plasterers arrive. Ducted systems suit Taunton 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.
Prices in Somerset
Our South West England guide price for ducted air conditioning is £5,450–£14,950 per system, VAT included. That is close to the UK middle for this kind of work. What moves a quote in Somerset up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £7,450–£10,950 here.
Single zone
One ducted unit serving two or three rooms from a loft or void.

Motorised dampers or two units for separate floors or room groups.
Whole home
Multiple ducted units with linear slot diffusers and smart control.
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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
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. On a survey in Somerset 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.
