Air conditioning for extensions and kitchen-diners in Neath
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. An extension in Neath with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Neath, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Neath is about 7 miles from Swansea and falls within our West Glamorgan coverage. Postcode districts we cover here include SA11.
Prices in Neath
For Neath, expect roughly £1,345 to £4,095 per space, VAT included, adjusted for typical South and Mid Wales rates. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. 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. For reference, the Large single option in Neath (one 5–7 kW unit for a large glazed space) usually comes to 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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Neath 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
We book surveys in Neath at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
