Multi-split air conditioning in Richmond
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. In a house in Richmond with a usable loft, multi-split pipes can often run through it so the front stays clear.
Twin and triple systems suit Richmond homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Richmond is about 8 miles from central London and falls within our London coverage. We cover TW9 and the streets around them.

For Richmond, expect roughly £3,245 to £10,245 for 2–4 rooms, VAT included, adjusted for typical London rates. London is one of the dearer parts of the UK for trades, which shows in the range. 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.

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 Richmond 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.
