Multi-split air conditioning in Greenwich
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. In a house in Greenwich with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Greenwich flats and maisonettes where only a balcony or one rear wall is available. Our London coverage takes in Greenwich, about 5 miles from central London. Coverage includes SE10.
Prices in Greenwich
For Greenwich, expect roughly £3,245 to £10,245 for 2–4 rooms, VAT included, adjusted for typical London rates. That is above the UK middle, mainly because labour and access cost more in London. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our London figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £4,395–£7,195.
Twin
Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.
Triple
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
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 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. We book surveys in Greenwich at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
