A REGO certificate is issued by Ofgem for each megawatt-hour (MWh) of electricity generated from eligible renewable sources in Great Britain. While it doesn’t deliver the electrons to your site, it does provide a trusted audit trail showing that an equivalent amount of green generation has taken place. For corporate users, accepting REGOs means you can show that your supply contracts align with your decarbonisation goals and regulatory reporting obligations.


When you enter a green energy tariff or a renewable purchase arrangement, your supplier or you directly match your usage with corresponding REGOs. We support you by assessing whether your supply chain uses bundled REGOs (generation + certificate) or unbundled REGOs (certificate only), helping you assess the credibility of your “100 % renewable” claims. This insight supports corporate procurement towards stronger sustainability outcomes and avoids reputational risk from greenwashing.
For multi-site, high-consumption businesses the timing, region and technology behind REGO's matter. We provide strategic guidance on forward purchasing, certificate vintage and usage profiling. We integrate REGO management with your wider energy and sustainability roadmap, aligning certificate purchase, renewable PPAs, efficiency initiatives and Scope 2 reporting. With a robust approach, REGOs become more than compliance tickboxes; they form part of a credible, data-driven sustainability narrative.
