Ofgem's role is changing
Ofgem administers this scheme on behalf of the Department for the Economy; however, our role is changing.
We are transferring the administration of the Northern Ireland Non-Domestic Renewable Heat Incentive scheme to the Department for the Economy by 30 April 2026. Following constructive engagement with the Department, we issued our formal notice outlining this decision and the timeline.
We will continue to manage the administration of the scheme in the interim, to allow continuity of service for scheme participants and ensure a smooth handover.
There is no immediate change and scheme participants should continue to engage with Ofgem Non-Domestic Renewable Heat Incentive Register and with Ofgem in the normal way.
