Air conditioning for extensions and kitchen-diners in Aberystwyth
In Aberystwyth, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In South and Mid Wales, efficient heating is often as important as cooling.
An extension in Aberystwyth with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Aberystwyth sits around 40 miles from Carmarthen, inside our Dyfed area. That includes the SY23 postcode district.

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 Aberystwyth 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.
