Air conditioning for extensions and kitchen-diners in Canterbury
For a kitchen-diner in Canterbury, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon.
An extension in Canterbury with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Kent coverage takes in Canterbury, about 24 miles from Maidstone. Postcode districts we cover here include CT1.
Prices in Canterbury
Budget around £1,745–£5,445 per space including VAT for air conditioning for extensions and kitchen-diners in and around Canterbury. That is above the UK middle, mainly because labour and access cost more in South East England. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our South East England figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £2,495–£3,495.
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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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 Canterbury 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.
