Air-to-air heat pumps in St Austell
Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling. Homes in St Austell on electric, oil or LPG heating are the ones most likely to benefit from an air-to-air heat pump.
Ask at your St Austell survey whether the Boiler Upgrade Scheme grant could apply to your home. St Austell lies roughly 13 miles from Truro, and we cover it as part of Cornwall. We cover PL25 and the streets around them.
Prices in St Austell
Air-to-air heat pumps in St Austell typically come in at £2,950–£11,450 for 2–5 rooms including VAT, based on South West England rates. That is broadly in line with national guide prices. 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. On our South West England figures, the Small home option (three or four rooms heated and cooled) is about £4,450–£7,450.

Living room and main bedroom on one outdoor unit.

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
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%.
Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
St Austell is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
The survey
On a survey in St Austell the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. Surveys in St Austell cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
