Ducted air conditioning across Northamptonshire
Ducted systems suit Northampton loft conversions and new extensions where ceilings are being boarded anyway. In an older house in Northampton, 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.

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
We book surveys in Northamptonshire at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Northamptonshire cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
