Multi-split air conditioning in Northampton
In a house in Northampton with a usable loft, multi-split pipes can often run through it so the front stays clear. In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment.
Multi-split is a good fit for Northampton flats and maisonettes where only a balcony or one rear wall is available. We cover Northampton and the rest of Northamptonshire, including Corby and Kettering. We cover NN1 and the streets around them.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in Northampton 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. We book surveys in Northampton at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
