Air conditioning for extensions and kitchen-diners in Mold
In North Wales, an air-to-air system can be an efficient way to heat holiday homes and bungalows, with cooling as a bonus. For a kitchen-diner in Mold, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Mold, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Mold is about 10 miles from Wrexham and falls within our Clwyd coverage. That includes the CH7 postcode district.
Prices in Mold
Budget around £1,345–£4,195 per space including VAT for air conditioning for extensions and kitchen-diners in and around Mold. It is a touch below the UK middle, as trade rates in North Wales tend to be. 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. On our North Wales figures, the Large single option (one 5–7 kW unit for a large glazed space) is about £1,945–£2,695.
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
On a survey in Mold 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. 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.
