Air conditioning for extensions and kitchen-diners in Denbigh
Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible. An extension in Denbigh with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
For a kitchen-diner in Denbigh, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. We cover Denbigh as part of Clwyd, roughly 20 miles from Wrexham. Coverage includes LL16.
Prices in Denbigh
In North Wales, our guide range for air conditioning for extensions and kitchen-diners is £1,345–£4,195 per space, including VAT. It is a touch below the UK middle, as trade rates in North Wales tend to be. What moves a quote in Denbigh up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. 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
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.

We book surveys in Denbigh 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.
