Ducted air conditioning in Daventry
In an older house in Daventry, the loft and any existing bulkheads decide whether a ducted layout will work. Summer peaks in the East Midlands make bedrooms under the roof the hardest rooms to keep comfortable.
Ducted systems suit Daventry loft conversions and new extensions where ceilings are being boarded anyway. We cover Daventry as part of Northamptonshire, roughly 12 miles from Northampton. Homes in NN11 are all within our coverage.
Prices in Daventry
Budget around £5,245–£14,345 per system including VAT for ducted air conditioning in and around Daventry. It is a touch below the UK middle, as trade rates in the East Midlands tend to be. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. On our East Midlands figures, the Zoned option (motorised dampers or two units for separate floors or room groups) is about £7,145–£10,495.

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 Daventry 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.
