Wall-mounted air conditioning in Worthing
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. A single wall-mounted unit is often all a bedroom or sunny living room in Worthing needs.
Where a home in Worthing faces the street, the outdoor unit usually goes at the rear, out of sight. Worthing lies roughly 22 miles from Crawley, and we cover it as part of West Sussex. We cover BN11 and the streets around them.
Prices in Worthing
Guide prices around Worthing run from £1,395 to £3,595 per room including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Worthing up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical Popular work (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) lands around £1,895–£2,595 in this area.

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
A survey in Worthing 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 Worthing at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
