Air conditioning for extensions and kitchen-diners in Rayleigh
For a kitchen-diner in Rayleigh, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
An extension in Rayleigh with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Rayleigh sits around 6 miles from Southend-on-Sea, inside our Essex area. That includes the SS6 postcode district.
Prices in Rayleigh
Budget around £1,595–£4,995 per space including VAT for air conditioning for extensions and kitchen-diners in and around Rayleigh. The East of England is one of the dearer parts of the UK for trades, which shows in the range. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,295–£3,195 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
Surveys in Rayleigh cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
