Renewable Energy Guarantees of Origin certificates (REGOs) allow electricity suppliers to prove to their final customers that a given share of energy was produced from renewable sources.
Suppliers are required to hold REGOs in their accounts on the Renewables and Combined Heat and Power (CHP) Register by midday on 1 July following the previous disclosure period (1 April to 31 March) as part of the evidence for Fuel Mix Disclosure (FMD).
Requests to recognise EU Guarantees of Origin (GoOs) must also be agreed by this date.
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.
