Air conditioning for extensions and kitchen-diners in Newtown
In South and Mid Wales, efficient heating is often as important as cooling. An extension in Newtown with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Newtown, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Newtown is one of the main towns we cover in Powys, alongside Brecon and Llandrindod Wells. Homes in SY16 are all within our coverage.

Budget around £1,345–£4,095 per space including VAT for air conditioning for extensions and kitchen-diners in and around Newtown. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. 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 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.

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
Surveys in Newtown cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in Newtown 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.
