Air conditioning for extensions and kitchen-diners in Swansea
In Swansea, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
An extension in Swansea with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. We cover Swansea and the rest of West Glamorgan, including Neath and Briton Ferry. We cover SA1 and the streets around them.
Prices in Swansea
Budget around £1,345–£4,095 per space including VAT for air conditioning for extensions and kitchen-diners in and around Swansea. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our South and Mid Wales figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,895–£2,595.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. 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.
