Multi-split air conditioning in Crawley
The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. In a house in Crawley with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Crawley flats and maisonettes where only a balcony or one rear wall is available. Crawley is one of the main towns we cover in West Sussex, alongside Worthing and Bognor Regis. Postcode districts we cover here include RH11 and RH77.
Prices in Crawley
Guide prices around Crawley run from £2,995 to £9,445 for 2–4 rooms including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Crawley up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical Triple work (three rooms with mixed indoor styles and Wi-Fi control throughout) lands around £4,095–£6,645 in this area.
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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
We book surveys in Crawley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Crawley 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.
