Is there financial support for heat pumps?

The Renewable Heat Incentive (RHI) offers support for domestic and non-domestic installations.

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, plus eligible systems installed since 15 July 2009, including (but not limited to) those who received the Renewable Heat Premium Payment (RHPP) grant.

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.

For information on RHI support for non-domestic installations, please see our page  How will the Renewable Heat Incentive support non-domestic installations?

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.
