Multi-split air conditioning in Hayes
Twin and triple systems suit Hayes homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
In a house in Hayes with a usable loft, multi-split pipes can often run through it so the front stays clear. We cover Hayes as part of London, roughly 13 miles from central London. Coverage includes UB3 and UB8.
Prices in Hayes
Budget around £3,245–£10,245 for 2–4 rooms including VAT for multi-split air conditioning in and around Hayes. 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. For reference, the Triple option in Hayes (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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
A survey in Hayes 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. We book surveys in Hayes at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
