Air conditioning for flats and apartments across South Glamorgan
Balcony-mounted outdoor units are often the neatest solution for flats in Cardiff. In Cardiff apartment blocks, the freeholder's consent is usually the first thing to sort out. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
Prices in South Glamorgan

Labour rates in South and Mid Wales keep this slightly under the national middle.

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%.
Consent and planning for flats
For flats in South Glamorgan, the lease and the freeholder's consent come first. Planning rules for blocks of flats are stricter than for houses, and we check them before quoting. In Wales, the rules for blocks of flats differ from those for houses, so we check with the council before quoting.
The survey
