Multi-split air conditioning in Welling
Multi-split is a good fit for Welling flats and maisonettes where only a balcony or one rear wall is available. 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.
Twin and triple systems suit Welling homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Our London coverage takes in Welling, about 10 miles from central London. Coverage includes DA16.
Prices in Welling
Guide prices around Welling run from £3,245 to £10,245 for 2–4 rooms including VAT. That is above the UK middle, mainly because labour and access cost more in London. What moves a quote in Welling up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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

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.
