Air-to-air heat pumps across Orkney, Shetland and the Western Isles
We size every heat pump in Stornoway for a cold winter day, then check the cooling side is right for summer. Homes in Stornoway on electric, oil or LPG heating are the ones most likely to benefit from an air-to-air heat pump. Wind and salt air in the north of Scotland mean outdoor unit placement and protection need extra thought.
Prices in Orkney, Shetland and the Western Isles
Our Highlands, Islands and North East Scotland guide price for air-to-air heat pumps is £2,645–£10,195 for 2–5 rooms, VAT included. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. On our Highlands, Islands and North East Scotland figures, the Small home option (three or four rooms heated and cooled) is about £3,945–£6,645. Travel, ferry or accommodation costs are not in these figures; they are quoted as a fixed amount in writing before you book.

The Boiler Upgrade Scheme does not cover Scotland; Home Energy Scotland can tell you what support is available.
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 Scotland, planning conditions for outdoor units depend on the property type and location; conservation areas and listed buildings need particular care.

Surveys in Orkney, Shetland and the Western Isles are arranged around travel.
