Multi-split air conditioning in Brighton
Twin and triple systems suit Brighton homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. 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 Brighton with a usable loft, multi-split pipes can often run through it so the front stays clear. As well as Brighton itself, our East Sussex coverage takes in Eastbourne, Hastings and the towns around them. Postcode districts we cover here include BN2.
Prices in Brighton
Guide prices around Brighton 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 Brighton up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our South East England figures, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) is about £4,095–£6,645.
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
For most houses in Brighton, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Brighton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
