Unique Registered Investor Reference (URIR)

This key-term is relevant to Assignment of Rights, which came into effect on 27 June 2018.

When investor registration is successful, we will issue the registered investor with a URIR. This will be used to identify them on our system as a registered investor, and link them to any accredited renewable heating systems for which they have been nominated to receive RHI payments.Registered investors must provide their URIR to applicants in order for RHI payments to be assigned to them.
