Air conditioning for extensions and kitchen-diners in Northamptonshire

Air conditioning for extensions and kitchen-diners across Northamptonshire

An extension in Northampton with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Northampton, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit.

Prices in Northamptonshire

For Northamptonshire, expect roughly £1,395 to £4,245 per space, VAT included, adjusted for typical East Midlands rates. Labour rates in the East Midlands keep this slightly under the national middle. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our East Midlands figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,945–£2,745.

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 Northamptonshire, 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

At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. On a survey in Northamptonshire 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.
