Air-to-air heat pumps in Plymouth
We size every heat pump in Plymouth for a cold winter day, then check the cooling side is right for summer. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
Ask at your Plymouth survey whether the Boiler Upgrade Scheme grant could apply to your home. As well as Plymouth itself, our Devon coverage takes in Exeter, Paignton and the towns around them. Coverage includes PL2 and PL4.
Prices in Plymouth
Air-to-air heat pumps in Plymouth 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. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Small home option in Plymouth (three or four rooms heated and cooled) usually comes to 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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
If your home in Plymouth is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. On a survey in Plymouth 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.
