Multi-split air conditioning in Feltham
Twin and triple systems suit Feltham homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
In a house in Feltham with a usable loft, multi-split pipes can often run through it so the front stays clear. We cover Feltham as part of London, roughly 13 miles from central London. That includes the TW13 postcode district.
Prices in Feltham
Budget around £3,245–£10,245 for 2–4 rooms including VAT for multi-split air conditioning in and around Feltham. That is above the UK middle, mainly because labour and access cost more in London. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the Triple option in Feltham (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

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.
