Our renewable energy comes from a variety of sources.
Electricity generators from around Great Britain provide us with Renewable Energy Guarantee of Origin (REGO) certificates to confirm all the electricity generated by them is renewable. Each year, we give these REGOs to Ofgem (the government regulator for energy suppliers) to prove our green credentials.
