Multi-split air conditioning in Islington
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. In a house in Islington with a usable loft, multi-split pipes can often run through it so the front stays clear.
Twin and triple systems suit Islington homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. We cover Islington as part of London, roughly 3 miles from central London. We cover EC1P, EC4P, N1, N1C, N1P and N7 and the streets around them.
Prices in Islington
Multi-split air conditioning in Islington typically comes in at £3,245–£10,245 for 2–4 rooms including VAT, based on London rates. London is one of the dearer parts of the UK for trades, which shows in the range. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. On our London figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £4,395–£7,195.

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

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
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. On a survey in Islington 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.
