Renewable Energy Guarantees of Origin (REGOs) are a type of Energy Attribute Certificate (EAC) used in the UK to verify the source of renewable electricity and represent one megawatt-hour (MWh) of generation.
Issued by Ofgem (the Office of Gas and Electricity Markets), REGOs enable organisations to make credible renewable energy claims under the Greenhouse Gas Protocol, support initiatives such as RE100 and Science-Based Targets (SBTi), making them an essential tool for reducing Scope 2 emission and demonstrating climate leadership.
When on-site renewable generation or PPA procurement isn’t feasible—whether due to limited solar panels or other constraints—REGOs offer an accessible pathway to decarbonise your electricity consumption.
REGOs can help fulfill voluntary sustainability goals, such as RE100 and CDP commitments.
Each REGO is assigned a unique serial number, ensuring it can only be sold and redeemed once, which guarantees full traceability and prevents double-counting of renewable energy claims.
REGOs reflect your commitment to renewables and strengthen the market signal for clean electricity—helping build the case for long-term clean energy investment.

Our experience working with GoNetZero™ has been exceptional in supporting us to achieve our 100% renewable energy target by 2023. After careful evaluation of various options, the best alternative was to purchase RECs. The team at GoNetZero™ provided valuable guidance, allowing us to obtain RECs tailored to our specific needs.
