Air conditioning for extensions and kitchen-diners in Brackley
An extension in Brackley with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. The East Midlands gets warm, dry summer spells, and loft conversions and top-floor bedrooms are where the heat builds.
For a kitchen-diner in Brackley, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Brackley sits around 19 miles from Northampton, inside our Northamptonshire area. Postcode districts we cover here include NN13.
Prices in Brackley
Air conditioning for extensions and kitchen-diners in Brackley typically comes in at £1,395–£4,245 per space including VAT, based on East Midlands rates. That sits a little below the UK middle, reflecting typical East Midlands labour rates. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. 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.

One 3.5–5 kW unit for a medium extension.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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. We book surveys in Brackley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
