I left E.on and joined Octopus in December 2018 after they came up cheapest on a comparison site...as a student nurse I need to save every penny I can! I joined using a link from a random person on here where they, and I, got £50 credit. (Here is mine should you wish to use it: https://share.octopus.energy/frost-sky-425 I have had no issues, tjere are no exit fees, no contract, they have a 'dashboard' where you can see all transaction history, if you're in credit/debit, and they encourage you to give meter readings so your bills are accurate. So pleased I switched. They are now Which provider if 2019 and I agree, they're great! £50 credit for both you and I if you sign up using this link... Thank you ! https://share.octopus.energy/frost-sky-425
