Air conditioning for extensions and kitchen-diners in Blackwood
In Blackwood, a side wall of a single-storey extension is usually the neatest place for the indoor unit. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
For a kitchen-diner in Blackwood, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Blackwood sits around 19 miles from Bridgend, inside our Mid Glamorgan area. Postcode districts we cover here include NP12.
Prices in Blackwood
For Blackwood, expect roughly £1,345 to £4,095 per space, VAT included, adjusted for typical South and Mid Wales rates. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. What moves a quote in Blackwood up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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.

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
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. On a survey in Blackwood the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
