Multi-split air conditioning in Penarth
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. Multi-split is a good fit for Penarth flats and maisonettes where only a balcony or one rear wall is available.
In a house in Penarth with a usable loft, multi-split pipes can often run through it so the front stays clear. Penarth lies roughly 3 miles from Cardiff, and we cover it as part of South Glamorgan. Postcode districts we cover here include CF64.

Two rooms on one outdoor unit, wall-mounted indoor units, standard routes.

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
We book surveys in Penarth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Penarth 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.
