Our renewable energy sources

We make sure that all the electricity we supply to our customers comes from renewable sources. We've made agreements with electricity generators across Great Britain, and they provide us with Renewable Energy Guarantee of Origin (REGOs) certificates to confirm that all the electricity generated is renewable. Each year, we give these REGOs to Ofgem to show that we're 100% renewable. You can see below some of the places where we sourced our energy from last year.

If you're a customer then you can also have your say on where we source our energy on our Vote for your source page!
