Grants and Incentives for Renewable Energy

Renewable Heat Incentive & Feed-In-Tariffs

The Government has introduced cash incentives to encourage businesses and householders to invest in renewable energy technologies.

The main sources of funding for renewable technologies are; the Renewable Heat Incentive (RHI) and Feed-In Tariffs (FITs).

Renewable Heat Incentive (RHI)

The RHI applies to heat producing renewable technologies such as heat pumps, solar thermal and biomass. It is administered by the official regulator Ofgem.

Commercial RHI

This Scheme supports renewable heat installations in business, industry and the public sector. RHI payments are made over a period of 20 years with payments received quarterly. See Ofgem's easy guide to the non-domestic RHI here.

Tariff rates from 20/9/17 are as follows:

Technology Commercial RHI Tariff p/kWh from 20/09/17
Ground Source Heat Pump

9.09p for the first 1314 hours (tier 1)

2.71p for above 1314 hours (tier 2)

Air Source Heat Pumps     2.61p
Solar Thermal      10.44p less than 200 KWth
Biomass  2.9p to 2.06p size dependent 

Domestic RHI

On 9th April 2014 the Department of Energy and Climate Change (DECC) launched the Domestic Renewable Heat Incentive (RHI), the scheme is expected to be open to new entrants until 2020. Once you are accepted onto the scheme then the payments are received for 7 years. 

This is the first scheme of its kind in the world and offers homeowners payments to offset the cost of installing renewable systems in their properties.

The Scheme is administered by Ofgem, you can see their factsheet on the domestic RHI here.

In essence, households will be paid the following tariff for every kWh of renewable heat generated by a supported technology, the tariff is paid quarterly over a 7 year period. Current tariffs with effect from 20/09/17 are as follows:

Technology Domestic RHI Tariff pence/kWh Cap on payments
Ground/Water Source Heat Pump 19.86p 30,000KWh
Air Source Heat Pump 10.18p 20,000KWh
Solar Thermal      20.06p N/A
Biomass 6.54p 25,000Kwh

Feed-In Tariffs (FITs)

FITs provide ongoing payments to owners of renewable equipment which produce electricity, such as solar photovoltaic (PV) panels. hydro and wind turbines. For further details and current tariff tables please see
