We partner with other generators
We buy certificates of renewable energy
How do REGO certificates work?
The industry regulator, Ofgem, introduced the Renewable Energy Guarantee of Origin (REGO) to help you track your energy back to a renewable source.
A renewable generator could be a wind farm, a solar site or anywhere else renewable energy is created. As long as they tick all the right boxes, Ofgem give them REGO certificates for the energy they create and – crucially – put on the grid. Let’s say you use 2.9 megawatt hours of electricity a year (that’s the average according to Ofgem). Between our partners and our own sites, we generate two-thirds of that energy already. So then we’d buy an extra REGO certificate to match what’s left over. We do the same for all the electricity going to all the homes we serve, and all the small businesses who are eligible. Read our blog to learn more about how we source our renewable electricity.
The legal stuff
1. Electricity backed by 100% renewable sources. E.ON's renewable generation assets, agreements with UK wind generators and the purchase of renewable electricity certificates.
The electricity supplied to your home comes from the National Grid and DNOs.
