Frequently Asked Questions

How efficient is an air source heat pump?

A heat pump delivers 3–4 kWh of heat for every 1 kWh of electricity, making it 300–400% efficient. This compares with 85–95% efficiency for a gas boiler. The efficiency rating (SCOP) varies by brand, from 4.3 (Samsung) to 4.7 (NIBE).

How long does a heat pump last?

A well-maintained air source heat pump lasts 20–25 years, compared with 10–15 years for a gas boiler. Annual servicing costs around £100–£150. The longer lifespan helps offset the higher upfront cost over time.

What is the typical heat pump installation cost in Scotland?

A typical installation costs £8,000–£14,000 depending on brand, property size and complexity. Interest-free credit up to £30,000 is available subject to status. Zero-rated VAT applies to residential installations until 31 March 2027.

Do heat pumps work in cold Scottish weather?

Yes. All six brands we compare are rated for -25°C or lower. Scotland averages 3–5°C in winter. Daikin Altherma 3 R is rated to -28°C. Heat pumps are widely used in Norway, Sweden and Finland, which are far colder than Scotland.
