Renewable Energy Guarantees of Origin (REGO)

Renewable Energy Guarantees of Origin (REGOs) certificates allow electricity suppliers to demonstrate to their customers how much of the electricity they supply was produced from renewable sources.

Suppliers are required to upload REGOs to their accounts on the Renewables and Combined Heat and Power (CHP) Register by midday 1 July each year, following the previous disclosure period (1 April to 31 March), as part of the evidence for Fuel Mix Disclosure. Requests to recognise EU Guarantees of Origin (GoOs) must also be agreed by this date.

Further information is available in the creating an account section of the Renewables and CHP Register guide, and on the transfer of REGOs in the guidance for generators.

Submitting data and managing certificates

Generating stations accredited under the Renewable Energy Guarantees of Origin (REGO) scheme should submit data for generation within the period April to March of each year.

To find out more please visit the dedicated page on submitting data and managing certificates.[AM12] 

Please note: As of 1 January 2021, the EU no longer recognises UK REGOs. The UK Government announced in July 2022 to cease the recognition of EU GOOs from April 2023. The Government continues to accept EU GoOs for the 2022-23 reporting period. This will allow electricity suppliers in the UK to continue to use REGOs and EU GoOs to comply with their fuel mix disclosure obligations. We also expect market participants to be able to meet proof of supply requirements in GB, including explicit (no-deal arrangements for Continental interconnectors) trading arrangements.

Ofgem is unable to provide any guarantees with regards to whether UK REGOs retired by suppliers for the purpose of export out of the UK will be accepted in the EU. As such we encourage suppliers to seek independent advice.
