• Commercial RHI Tariff Table 2014

    The following are the current tariff rates for eligible installations under the Commercial Renewable Heat Incentive (RHI).

    The non-domestic RHI provides financial support for renewable heat technologies for the lifetime of the installation (to a maximum of 20 years). Payments are made on a quarterly basis.

    DECC announce changes to RHI Tariff rates quarterly under the degression mechanism. The current tariff period applies to applications with an accreditation date on or after 1 July 2014 and before 1 October 2014. New non-domestic RHI tariffs have also been announced and will come into effect on 1 October. They apply to applications with an accreditation date on or after 1 October 2014 and are listed in the tables below.

    Small biogas combustion Biogas combustion Less than 200 kWth NA 7.5 7.5
    Medium biogas combustion (commissioned on or after 4 December 2013) Biogas combustion 200 kWth and above & less than 600 kWth NA 5.9 5.9
    Large biogas combustion (commissioned on or after 4 December 2013) Biogas combustion 600 kWth and above NA 2.2 2.2

    Once you are accredited under the RHI, a tariff level will be assigned to your installation based on its technology and size. Payments will be made based on the actual heat output of the system.

    Payments begin to accrue from the date of accreditation of the installation. The date is confirmed in the accreditation confirmation letter emailed to successful applicants.
