Multi-split air conditioning in Northolt
In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep. Multi-split is a good fit for Northolt flats and maisonettes where only a balcony or one rear wall is available.
In a house in Northolt with a usable loft, multi-split pipes can often run through it so the front stays clear. We cover Northolt as part of London, roughly 11 miles from central London. Postcode districts we cover here include UB5.
Prices in Northolt
Multi-split air conditioning in Northolt typically comes in at £3,245–£10,245 for 2–4 rooms including VAT, based on London rates. That is above the UK middle, mainly because labour and access cost more in London. What moves a quote in Northolt up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our London figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £4,395–£7,195.

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 Northolt, 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
We book surveys in Northolt at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
