Before you book: air-to-air heat pumps in Stornoway
Most homes can run on a heat pump if the system is designed properly, and Stornoway is no different. The key is matching the heat pump and radiators to the home's heat loss.
Flats in Stornoway on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework. A survey in Stornoway covers indoor unit positions, pipe routes and hot water for homes across the Highlands and Islands.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Condensate drains and neat external pipe covers
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
For terraced homes in Stornoway, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Stornoway can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Stornoway property at survey.

Designing for Stornoway's winters
On the shortest day Stornoway gets only about 6 hours 24 minutes of daylight, with the sun around 8° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.
The steps for air-to-air heat pumps in Stornoway
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Stornoway home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Stornoway is in an area we cover by arrangement, so survey dates and any travel costs are confirmed individually in your quote.
Air-to-air heat pumps in Stornoway: questions
Can you service a heat pump in Stornoway that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stornoway, whoever fitted them. Tell us the make and model when you book.
Do I need new radiators for a heat pump in Stornoway?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Stornoway home gives a room-by-room list.
Where would the outdoor unit go on a Stornoway house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Stornoway home.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
