Ducted air conditioning in Penarth
In an older house in Penarth, the loft and any existing bulkheads decide whether a ducted layout will work. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
For a renovation in Penarth, the best time to plan ducted cooling is before the plasterers arrive. Penarth is about 3 miles from Cardiff and falls within our South Glamorgan coverage. Homes in CF64 are all within our coverage.

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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Penarth can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
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. We book surveys in Penarth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
