New build and renovation air conditioning in Plymouth
Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling. First-fix pipework in Plymouth extensions goes in while the joists and studs are open.
For new Plymouth extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. We cover Plymouth and the rest of Devon, including Exeter and Paignton. Postcode districts we cover here include PL2 and PL4.
Prices in Plymouth
For Plymouth, expect roughly £395 to £895 per indoor position (first fix), VAT included, adjusted for typical South West England rates. It sits near the middle of UK prices. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our South West England figures, the First and second fix option (complete install priced per room including units) is about £1,450–£2,950.

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.
