Air conditioning for extensions and kitchen-diners in Cardigan
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. An extension in Cardigan with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Cardigan, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our Dyfed coverage takes in Cardigan, about 22 miles from Carmarthen. That includes the SA43 postcode district.

Labour rates in South and Mid 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.

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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Cardigan can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
On a survey in Cardigan 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. Surveys in Cardigan cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
