Air conditioning for extensions and kitchen-diners in Whitstable
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. In Whitstable, a side wall of a single-storey extension is usually the neatest place for the indoor unit.
For a kitchen-diner in Whitstable, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Whitstable as part of Kent, roughly 23 miles from Maidstone. Homes in CT5 are all within our coverage.
Prices in Whitstable
Our South East England guide price for air conditioning for extensions and kitchen-diners is £1,745–£5,445 per space, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. 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

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