Air conditioning for extensions and kitchen-diners across Clwyd
An extension in Wrexham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Wrexham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible.
Prices in Clwyd
For Clwyd, expect roughly £1,345 to £4,195 per space, VAT included, adjusted for typical North Wales rates. Labour rates in North Wales keep this slightly under the national middle. 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. For reference, the Large single option in Clwyd (one 5–7 kW unit for a large glazed space) usually comes to about £1,945–£2,695.

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 Clwyd 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. Surveys in Clwyd cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
