Air conditioning for extensions and kitchen-diners in Kettering
In Kettering, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Summer peaks in the East Midlands make bedrooms under the roof the hardest rooms to keep comfortable.
An extension in Kettering with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Northamptonshire coverage takes in Kettering, about 12 miles from Northampton. We cover NN16 and the streets around them.

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.
