Air conditioning for extensions and kitchen-diners in Daventry
In Daventry, a side wall of a single-storey extension is usually the neatest place for the indoor unit. East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit.
For a kitchen-diner in Daventry, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Our Northamptonshire coverage takes in Daventry, about 12 miles from Northampton. Homes in NN11 are all within our coverage.
Prices in Daventry

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 Daventry, 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. A survey in Daventry usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
