Air conditioning for extensions and kitchen-diners across Gwent
For a kitchen-diner in Newport, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In Newport, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
Prices in Gwent
For Gwent, expect roughly £1,345 to £4,095 per space, VAT included, adjusted for typical South and Mid Wales rates. Labour rates in South and Mid Wales keep this slightly under the national middle. What moves a quote in Gwent 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.

One 5–7 kW unit for a large glazed space.

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
A survey in Gwent usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. On a survey in Gwent 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.
