Air conditioning for extensions and kitchen-diners in Deeside
Mild North Wales summers mean heat pump heating is usually the headline benefit. For a kitchen-diner in Deeside, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Deeside, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Deeside lies roughly 11 miles from Wrexham, and we cover it as part of Clwyd. Postcode districts we cover here include CH5 and CH1.
Prices in Deeside
Air conditioning for extensions and kitchen-diners in Deeside typically comes in at £1,345–£4,195 per space including VAT, based on North Wales rates.

Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,945–£2,695 here.

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.
