Multi-split air conditioning across Northamptonshire
In a house in Northampton with a usable loft, multi-split pipes can often run through it so the front stays clear. Multi-split is a good fit for Northampton flats and maisonettes where only a balcony or one rear wall is available. The East Midlands gets warm, dry summer spells, and loft conversions and top-floor bedrooms are where the heat builds.

For Northamptonshire, expect roughly £2,345 to £7,445 for 2–4 rooms, VAT included, adjusted for typical East Midlands rates. Labour rates in the East Midlands keep this slightly under the national middle. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) would typically be £3,195–£5,245 here.

Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.

Three rooms with mixed indoor styles and Wi-Fi control throughout.
Quad
Four or five rooms, longer concealed runs or a ducted unit in a loft void.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
