What to know about air-to-air heat pumps in Lerwick
Homes around Lerwick range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
A survey in Lerwick covers indoor unit positions, pipe routes and hot water for homes across the Highlands and Islands. Extensions and garden rooms in Lerwick that are hard to connect to the main heating can have their own air-to-air unit.
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.
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
- Households that already have, or will add, a separate source of hot water
What's included
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
For terraced homes in Lerwick, 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 Lerwick 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 Lerwick property at survey.
Air-to-air heat pumps costs around Lerwick
These are guide prices for the Highlands and Islands, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,700–£5,600 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,500–£8,950 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water.

Air-to-air heat pumps in Lerwick: questions
How soon can you survey a home in Lerwick?
Survey dates depend on how busy installers are in the Highlands and Islands. We offer the next available dates when you enquire and confirm them in writing.
How long does a heat pump survey take in Lerwick?
A home survey in Lerwick usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Can you service a heat pump in Lerwick that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lerwick, whoever fitted them. Tell us the make and model when you book.
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.
