Air conditioning for extensions and kitchen-diners in Clydach
For a kitchen-diner in Clydach, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
An extension in Clydach with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Clydach as part of West Glamorgan, roughly 5 miles from Swansea. That includes the SA6 postcode district.
Prices in Clydach
Our South and Mid Wales guide price for air conditioning for extensions and kitchen-diners is £1,345–£4,095 per space, VAT included. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Large single option in Clydach (one 5–7 kW unit for a large glazed space) usually comes to about £1,895–£2,595.

One 3.5–5 kW unit for a medium extension.

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 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
The survey
A survey in Clydach 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. 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.
