Support for domestic heat pump installations
Heat pump systems are supported through tariff payments as part of the domestic RHI. The payments are available to new installations of eligible equipment.
For more information on RHI support for domestic installations, please see our page How will the Renewable Heat Incentive support domestic installations?
Support for non-domestic heat pump installations
Non-domestic ground- or water source heat pump systems, e.g. for a B&B, a pub, a public swimming pool or industrial installations, will receive an RHI tariff payment for every unit of heat generated.
Note: Air Source Heat Pumps are currently not supported through the non-domestic RHI (but are through the domestic RHI).
For ground or water source heat pumps (as well as deep geothermal systems) smaller than 100kWth the tariff is 4.9 pence per kWh.
For systems of 100kWth or above the RHI tariff is 3.6p per kWh.
To illustrate this: Say a 10kW ground source heat pump provides 10,000kWh per year for a small educational or commercial building. The RHI tariff payment will be 10,000kWh x 4.9p/kWh = £490 per year.
Tariffs are guaranteed over a 20 year lifetime and will be adjusted with inflation. All heat generated will have to be metered using heat meters.

Eligibility for support
To be eligible, both the equipment and the installer for domestic and small (<45kW) non-domestic heat pump systems will have to be accredited under the Microgeneration Certification Scheme (MCS). You can use the MCS website to find accredited installers.
