Choose the right heat pump type
There are five heat pump technologies installed in UK homes. Each has its own benefits, disadvantages and ideal use case. Pick a type to read in detail.
Air source (ASHP)
The UK's dominant heat pump type. Outdoor unit, eligible for £7,500 BUS, suits most homes.
Ground source (GSHP)
Higher efficiency, no outdoor unit, premium up-front cost. For rural homes with grounds.
Water source (WSHP)
Highest seasonal efficiency. For properties near a river, lake or aquifer.
Exhaust air (EAHP)
Pulls heat from extract air. Only for airtight MVHR new-builds.
Hybrid
Heat pump + retained boiler. Not BUS-eligible. Niche cases only.

What MCS certification actually means
Quality scheme
MCS (Microgeneration Certification Scheme) is the UK quality mark for installers of small-scale renewable energy systems, including heat pumps. Certification is checked against engineering and customer-protection standards.
Grant eligibility
You can only claim the £7,500 Boiler Upgrade Scheme grant in England and Wales if your installer is MCS-certified. The Home Energy Scotland grant has similar requirements.
Independent listing
Every installer here appears on the public MCS register. We don't charge for listings. The data refreshes from the public register; see the disclaimer for our update cadence.
