New build and renovation air conditioning across Dyfed
First-fix pipework in Carmarthen extensions goes in while the joists and studs are open. For new Carmarthen 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 Dyfed
Air conditioning for new builds and renovations in Dyfed typically comes in at £365–£795 per indoor position (first fix) including VAT, based on South and Mid Wales rates. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. 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.
The survey
Surveys in Dyfed cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. A survey in Dyfed usually takes one to two hours.
