Wall-mounted air conditioning in Chichester

Wall-mounted air conditioning in Chichester

The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first. Where a home in Chichester faces the street, the outdoor unit usually goes at the rear, out of sight.

A single wall-mounted unit is often all a bedroom or sunny living room in Chichester needs. Chichester sits around 32 miles from Crawley, inside our West Sussex area. Coverage includes PO19.

Prices in Chichester

Wall-mounted air conditioning in Chichester typically comes in at £1,395–£3,595 per room including VAT, based on South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Chichester up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £1,895–£2,595 here.

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. On a survey in Chichester the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
