New build and renovation air conditioning across Devon
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. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
Prices in Devon
For Devon, 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. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. For reference, the First and second fix option in Devon (complete install priced per room including units) usually comes to 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
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 Devon cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. We book surveys in Devon at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
