REGO-backed fuel mix
A REGO-backed green fuel mix is electricity certified as 100% renewable. Standing for Renewable Energy Guarantees of Origin, REGOs are issued for every unit of renewable energy generated.

Brown fuel mix
A brown fuel mix is energy generated mainly from non-renewable sources. While the UK’s businesses are increasingly adopting a green energy mix, these conventional products are still a key part of the national grid.

FAQs about our fuel mix
The main types of renewable energy used are wind, biomass, hydro and solar. Our REGO-backed green energy fuel mix, for instance, is made up of 76.7% wind, 14% biomass, 6.4% hydro, and 2.9% solar.
A REGO certificate is the main way to prove your electricity has been generated by renewable sources. Our REGO-backed fuel mix provides you with a fuel mix disclosure statement. This confirms every unit of electricity your business uses is guaranteed as being renewable.
For larger companies, a Power Purchase Agreement (PPA) from a variety of renewable and low-carbon technologies can offer further proof of your sustainability credentials.
Green energy fuel mixes no longer come at a premium price like they once did. In recent years, the cost of generating electricity from renewable sources has fallen considerably. Today, it’s true that the cost is often on par with traditional energy sources.
