  • Evidence of property’s EPC rating is not required for these technologies
  • The tariff period is 20 years for hydro and wind, 10 years for micro CHP.
  • The definition of ‘hydro generating station’ includes small tidal projects.
  • The tariffs are to be reviewed every three months and will be revised according to deployment rates.

Domestic RHI Tariff Rates

The Domestic RHI scheme aims to support homeowners and landlords who have chosen to invest in renewable heating technologies like biomass boilers and stoves,
heat pumps or solar thermal panels.

The table below summarises the latest tariffs available for each technology:

 

Air source heat pump

Biomass

Ground source heat pump

Solar thermal

Tariff (p/k Wh renewable heat)

(Applications submitted between 1 July 2015 and 30 Sept. 2015 incl.)

7.42 7.14 19.10 19.51

Tariff rates updated – 29 May 2015

  • All tariff rates for the Domestic RHI will be adjusted in line with the Retail Price Index (RPI) on 1 April of each year.
  • Payments are based on the estimated annual heat demand on your Energy Performance Certificate (EPC) or the estimated annual generation on your Microgeneration Certification Scheme (MCS) certificate if you have solar thermal.
  • The Domestic RHI tariffs are set by the Department of Energy and Climate Change (DECC). They have to keep the Domestic RHI within budget and they do this by
    lowering the tariff rates for new applicants. This is called ‘degression’ and it happens if uptake of the scheme is higher than the approved budget for that quarter.
  • Once applications been approved, payments are made quarterly in arrears for seven years, providing they continue to meet the scheme rules.

Full details can be found on the Ofgem website: The Domestic RHI – Tariffs and payments.

Non Domestic RHI Tariff Rates

All tariff rates apply from 1 April 2015 as they have been updated to include the Retail Price Index (RPI) uplift of 1.6%.

  • The Non-Domestic RHI provides financial support for renewable heat technologies for the lifetime of the installation (for 20 years).
  • Payments are made on a quarterly basis.
  • Once accredited, a tariff level will be assigned to your installation based on its technology (eg biomass, heat pump, solar) and size.
  • Payments will be made based on the actual heat output of the system.
