Multi-split air conditioning in Littlehampton
Multi-split is a good fit for Littlehampton flats and maisonettes where only a balcony or one rear wall is available. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Twin and triple systems suit Littlehampton homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. We cover Littlehampton as part of West Sussex, roughly 26 miles from Crawley. Coverage includes BN17.

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
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 Littlehampton cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
