Air conditioning for extensions and kitchen-diners in Sittingbourne
For a kitchen-diner in Sittingbourne, 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 Sittingbourne with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Sittingbourne is about 11 miles from Maidstone and falls within our Kent coverage. We cover ME10 and the streets around them.
Prices in Sittingbourne
Budget around £1,745–£5,445 per space including VAT for air conditioning for extensions and kitchen-diners in and around Sittingbourne. 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. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 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
For most houses in Sittingbourne, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
