Frequently asked questions


Are all these suppliers providing guaranteed coal-free/ nuclear-free electricity and frack-free gas?

Ecotricity and Good Energy only offer 100% renewable electricity – fossil fuel and nuclear free. Both companies oppose fracking.


Electricity comes from the National Grid’s mix of renewables, nuclear and fossil fuel power stations, so how can the supply from these companies be green?

All energy gets fed into the National Grid, whether it’s from renewable or non-renewable sources, and then through a local distribution network to your home. Our green energy partners make sure that every unit of electricity you use is matched 100% with a unit generated from renewable sources. By choosing one of their tariffs, you’re helping to make the grid greener.


Why didn't the green energy company I use make your top two?

First of all, if you’re already with a green energy supplier, thanks – you’re already helping to save the planet. The energy suppliers we picked only have tariffs that offer 100% green electricity. We also preferred ones that were making other efforts to hasten the end of fossil fuel use, like buying directly from renewable generators or generating their own power. Here’s a side-by-side comparison of our top two.

Please direct any questions about each company’s approach to payment methods, discounts, smart meters etc to their help pages: Ecotricity, Good Energy. But if you have any questions about our energy switch campaign, our business partners or anything else, please contact us.
