Multi-split air conditioning in Blackheath
In a house in Blackheath with a usable loft, multi-split pipes can often run through it so the front stays clear. 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.
Twin and triple systems suit Blackheath homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Our London coverage takes in Blackheath, about 6 miles from central London. Homes in SE3 are all within our coverage.
Prices in Blackheath
Multi-split air conditioning in Blackheath 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. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Triple option in Blackheath (three rooms with mixed indoor styles and Wi-Fi control throughout) usually comes to 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
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
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. A survey in Blackheath 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.
