Air conditioning for extensions and kitchen-diners in Gorseinon
Humid summer spells in South Wales make dehumidifying and cooling equally welcome. An extension in Gorseinon with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Gorseinon, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Gorseinon lies roughly 5 miles from Swansea, and we cover it as part of West Glamorgan. Homes in SA4 are all within our coverage.
Prices in Gorseinon
Guide prices around Gorseinon run from £1,345 to £4,095 per space including VAT. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,895–£2,595 here.

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