It is advisable to register schemes as soon as possible, so as to obtain support at the current tariff levels rather than the lower tariff levels expected in the future.

The tariff payments are scheduled to be reviewed each quarter under the digression system. Apply today.

Key elements of the RHI scheme

  • Must be heating an enclosed building with steam or hot water radiators, underfloor, convector heating, any form of space heating, water to air etc.

  • All form of process heating including internal and external uses.
  • Outdoor swimming pools and certain other facilities do not qualify for RHI income (they can still be heated but will not receive the tariff payment).

  • Systems must not have received grant funding already; or, if they have, it must have been paid back.
  • Heat generation will be measured by heat meters and are subject to complex rules concerning their placement, specification and reporting thereon.
  • The plant must provide heat for at least one eligible heat use: heating a space, heating water or carrying out a process, where the heat is used within a building or used outside a building for drying and/or cleaning on a commercial basis (see RHI Guidance Volume 1).
