Air conditioning for extensions and kitchen-diners in Corby
An extension in Corby with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Summer peaks in the East Midlands make bedrooms under the roof the hardest rooms to keep comfortable.
For a kitchen-diner in Corby, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Corby lies roughly 19 miles from Northampton, and we cover it as part of Northamptonshire. Postcode districts we cover here include NN17.

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
For most houses in Corby, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
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. We book surveys in Corby at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
