Thinking of switching to low-carbon heating? Here’s everything Scottish homeowners and businesses need to know about heat pumps—how they work, how much they cost, and how to unlock grant funding to help you make the move.
What is a Heat Pump?
A heat pump is a highly efficient, low-carbon alternative to traditional gas or oil heating systems. Instead of burning fuel, it moves existing heat from the air or ground into your home—making it clean, quiet, and future-proof.
There are two main types:
- Air Source Heat Pump (ASHP):
Draws warmth from the outside air (even in cold weather!) and transfers it into your home through radiators or underfloor heating. - Ground Source Heat Pump (GSHP):
Uses the constant underground temperature to heat your home, via pipes buried in the garden or beneath the property.
Both types can also provide cooling in summer and work with your existing hot water system.
How Do Heat Pumps Work?
Think of a heat pump as a fridge in reverse. It extracts low-temperature heat from outside and uses a refrigerant cycle to compress and amplify that heat to a usable temperature indoors.
Even when it’s -15°C outside, modern heat pumps can still work efficiently—especially important in the Scottish climate.
Performance You Can Trust
- SCOP (Seasonal Coefficient of Performance):
A good heat pump has a SCOP of 3 or more, meaning it produces 3 units of heat for every 1 unit of electricity used. - MCS Certification:
All heat pump installations by PEAK Renewables are MCS-accredited, ensuring compliance with top industry standards and unlocking access to government grants.
Are Heat Pumps Suitable for Scottish Homes?
Yes! In fact, Scotland is one of the best places in the UK to switch.
Ideal for:
- Homes with good insulation or new builds
- Properties using oil or LPG heating
- Rural and off-grid locations
- Eco-conscious homeowners looking to cut carbon and running costs
Top Tip: If your home has an EPC rating of D or above, you’re likely a great candidate—and may qualify for grant support.
Running Costs vs Gas & Oil
Switching to a heat pump can lower your annual energy bills, particularly if you’re coming from oil or electric-only heating.
| Fuel Type | Avg Annual Cost | With Heat Pump |
|---|---|---|
| Oil | £1,500–£2,000 | ↓ up to 50% |
| LPG | £1,400–£1,800 | ↓ up to 45% |
| Electric | £2,000+ | ↓ up to 55% |
| Gas | Competitive | Can still reduce bills depending on tariff & usage |
Add solar and storage to the mix? The savings multiply.

Heat Pump Grants in Scotland (2025 Update)
The Boiler Upgrade Scheme (BUS) offers up to:
- £7,500 for an Air Source Heat Pump
- £7,500–£9,000 for a Ground Source Heat Pump
Other support includes:
- Home Energy Scotland Loans: Interest-free up to £15,000 for renewables and efficiency upgrades
- ECO4 Scheme (for eligible households on certain benefits)
- VAT Exemption: 0% VAT on heat pumps until at least 2027
We help every customer check their eligibility and apply with confidence.
Can You Use Heat Pumps with Solar Panels?
Absolutely—and it’s a smart move.
Solar panels generate free electricity, which a heat pump can use to further reduce your bills and carbon footprint. Add a battery and you can run your heating with stored solar power during off-peak times.
