Ducted air conditioning across Dorset
Ducted systems suit Bournemouth loft conversions and new extensions where ceilings are being boarded anyway. In an older house in Bournemouth, the loft and any existing bulkheads decide whether a ducted layout will work. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
Prices in Dorset
Ducted air conditioning in Dorset typically comes in at £5,450–£14,950 per system including VAT, based on South West England rates. That is close to the UK middle for this kind of work. What moves a quote in Dorset 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.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
On a survey in Dorset 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. 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.
