Northern Ireland Renewable Heat Incentive

The Department of Enterprise, Trade and Investment (DETI) suspended the Non-Domestic Northern Ireland Renewable Heat Incentive (RHI) to new applications from 29 February 2016.

From 9 May 2016, the new Department for the Economy (DfE) assumed the roles and responsibility of DETI including policy responsibility for the Northern Ireland Non-Domestic RHI. We continue to administer the scheme on DfE’s behalf. The Great Britain RHI scheme is unaffected. For further information see our frequently asked questions.

What is the Northern Ireland RHI?

It’s a government incentive, similar to the one in Great Britain, that helps businesses, public sector, and other non-domestic and non-profit organisations in Northern Ireland meet the cost of installing renewable heat technologies. DfE sets the policy and tariffs.

Further information about the scheme is available on the DfE website.

Changes to the scheme

May 2019, removal of the formal review process

Following the Ofgem consultation, the option to have a formal review following a decision made by Ofgem has been removed. The Statutory review is the only review option for decisions made by Ofgem and this review will be carried out by the Department for the Economy. Details on how to request a Statutory review from the Department for the Economy will be included in all future decision letters from Ofgem.

18 November 2015, DETI introduced some changes to the scheme including:

  • Relocation of accredited installations.
  • The change of banding and introduction of a tiered tariff for small and medium commercial biomass and a 400,000kWhth annual cap on payments.
  • Certain CHP installations could join the scheme which are accredited under the Renewables Obligation.

Changes to biomass tariffs on the Northern Ireland RHI

On 1st April 2017, DfE introduced some changes to the scheme affecting installations in Northern Ireland accredited before 18 November 2015. These changes introduced tiering and capping for small and medium biomass installations.  If you have any questions about these regulation changes, please contact the Department for the Economy. The Ofgem Non-Domestic Renewable Heat Incentive (RHI) Register has been updated to take account of these changes and you should continue to submit your quarterly data in the usual way.

Information on these and other minor changes are in the Northern Ireland RHI Guidance Volumes 1 and 2.
