Air conditioning for flats and apartments in Crawley
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. In Crawley apartment blocks, the freeholder's consent is usually the first thing to sort out.
Balcony-mounted outdoor units are often the neatest solution for flats in Crawley. We cover Crawley and the rest of West Sussex, including Worthing and Bognor Regis. That includes the RH11 and RH77 postcode districts.
Prices in Crawley
Air conditioning for flats and apartments in Crawley typically comes in at £1,645–£7,245 per flat, one room to the whole flat including VAT, based on South East England rates. South East England is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. Typical Two rooms work (twin multi-split for living room and main bedroom) lands around £3,245–£4,795 in this area.
Single room
One wall unit with a balcony outdoor unit.
Two rooms

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%.
Consent and planning for flats
Flats need more care: get your freeholder's written consent first, and expect the planning rules for a block of flats in Crawley to be stricter than for a house. In England, permitted development allows one outdoor unit of up to 0.6 m³ on a block of flats; anything more needs planning 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. Surveys in Crawley cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
