Ducted air conditioning in Truro
Ducted systems suit Truro loft conversions and new extensions where ceilings are being boarded anyway. In the South West, a system that heats well through damp winters is often as valuable as summer cooling.
In an older house in Truro, the loft and any existing bulkheads decide whether a ducted layout will work. As well as Truro itself, our Cornwall coverage takes in Redruth, Falmouth and the towns around them. Homes in TR1 are all within our coverage.
Prices in Truro
Budget around £5,450–£14,950 per system including VAT for ducted air conditioning in and around Truro. It sits near the middle of UK prices. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. 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
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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. 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.
