New build and renovation air conditioning across South Glamorgan
Renovations in Cardiff are the easiest jobs to make invisible, because the pipework goes in before the plaster. For new Cardiff extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
Prices in South Glamorgan
Our South and Mid Wales guide price for air conditioning for new builds and renovations is £365–£795 per indoor position (first fix), VAT included. Labour rates in South and Mid Wales keep this slightly under the national middle. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical First and second fix work (complete install priced per room including units) lands around £1,345–£2,695 in this area.

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%.
Working with your builder
On build projects the main thing is timing with your builder and electrician; we fit first-fix pipework before plastering and agree the outdoor unit position early.
