Air conditioning for extensions and kitchen-diners in Northampton
East Midlands summers bring dry, sunny spells, so glazing and orientation matter most when sizing a unit. For a kitchen-diner in Northampton, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Northampton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. As well as Northampton itself, our Northamptonshire coverage takes in Corby, Kettering and the towns around them. Coverage includes NN1.
Prices in Northampton
Budget around £1,395–£4,245 per space including VAT for air conditioning for extensions and kitchen-diners in and around Northampton. That sits a little below the UK middle, reflecting typical East Midlands labour rates. What moves a quote in Northampton up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,945–£2,745 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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 Northampton, 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
On a survey in Northampton 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. 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.
