Conservatory air conditioning in Cardiff
Humid summer spells in South Wales make dehumidifying and cooling equally welcome. Conservatories and orangeries in Cardiff can swing from too hot in July to too cold in January.
If your conservatory in Cardiff faces south, that is where overheating is worst. We cover Cardiff and the rest of South Glamorgan, including Barry and Penarth. That includes the CF10, CF11, CF14, CF15, CF23 and CF24 postcode districts.
Prices in Cardiff
For Cardiff, expect roughly £1,345 to £3,145 per system, VAT included, adjusted for typical South and Mid Wales rates.

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