Air conditioning for extensions and kitchen-diners in Tenby
In Tenby, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
An extension in Tenby with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Dyfed coverage takes in Tenby, about 21 miles from Carmarthen. We cover SA70 and the streets around them.

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.

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