New build and renovation air conditioning across West Glamorgan
Renovations in Swansea are the easiest jobs to make invisible, because the pipework goes in before the plaster. For new Swansea 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.

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
Because the pipework is built into the structure, coordination with your builder matters more than planning here; the outdoor unit follows the same rules as any other installation.
