About the REGO scheme

What is it?

The Renewable Energy Guarantees of Origin (REGO) scheme provides transparency to consumers about the proportion of electricity that suppliers source from renewable generation.

All EU Member States are required to have such a scheme.

Please note: Ofgem’s administration of the REGO scheme and fuel mix disclosure is not affected by EU Exit. We will continue to issue REGOs and accept guarantees of origin (GoOs) from EU member states after EU Exit Day. REGOs issued in the UK will no longer be recognised by EU member states after exit day in a no deal scenario. Under the draft withdrawal agreement published by the UK government on 25 November 2018, there will be a transition period, during which UK REGOs will continue to be recognised by EU member states until 31 December 2020.

What do we do?

We administer the scheme for generation in Great Britain on behalf of the Department for Business, Energy & Industrial Strategy (BEIS), and in Northern Ireland on behalf of the Northern Ireland Authority for Utility Regulation (NIAUR).

We regularly report to HM Revenue & Customs (HMRC) and BEIS, and are responsible for the annual Fuel Mix Disclosure (FMD) compliance deadline.

How does it work?

We issue one REGO certificate per megawatt hour (MWh) of eligible renewable output to generators of renewable electricity.

The purpose of the certificate is to prove to the final customer that a given share of energy was produced from renewable sources. As such, the primary use of REGOs in Great Britain and Northern Ireland is for FMD. FMD requires licensed electricity suppliers to disclose to potential and existing customers the mix of fuels (coal, gas, nuclear, renewable and other) used to generate the electricity supplied.

Who can apply?

Renewable generators of any size in Great Britain and Northern Ireland can apply for the scheme.

Applications for accreditation under the scheme are made via the Renewables and CHP register. For generators to receive certificates, generation data must be submitted via the register. Once issued, the certificates can be transferred to other Renewables and CHP register account holders.
