Support for domestic heat pump installations
Until Spring 2014, support for domestic heat pumps will be through Renewable Heat Premium Payment (RHPP) scheme, giving grants of £850 for an air-to-water heat pump system and £1,250 for a ground or water source heat pump. Only houses without mains gas will be eligible - for example those looking to replace oil, liquid gas, solid fuel or direct electric heating.
From Summer 2014, heat pump systems will be supported through tariff payments as part of the second domestic phase of the RHI. Details for this are still unknown, but DECC have announced that this phase will be open for all eligible (see below) installations installed since 15 July 2009, including (but not limited to) those who received Premium Payments.

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 non-domestic RHI tariffs!
For ground- or water source heat pump systems (as well as deep geothermal systems) smaller than 100kWth the tariff is 4.3 pence per kWh.
For systems of 100kWth or above the RHI tariff is 3p/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 4.3p/kWh = £430 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 www.microgenerationcertification.org to find accredited installers and products.
