A warm welcome to all Symbio Energy customers.

We've set up most of your accounts in our systems right now. If you've not already heard from us, get in touch.

Last update - 1 February.

This information is correct for the majority of customers, however there may be some exceptions.


  • Your E.ON Next account is set up: You should have received your new account number. You'll be able to log in to your online account to check your details and set up your Direct Debit

  • Symbio Energy credit balance transferred: If your Symbio account was in credit on 3 October, you'll be able to see the credit on your E.ON Next online account and your first bill.

  • Final bills: If you'd already left Symbio Energy to go to another supplier, we've sent you any credit that's due

  • Your first E.ON Next bill: We've now produced your first bill and let you know it's ready. It includes any credits due from Symbio Energy.

  • If you left Symbio Energy after we took over supply, then we’ve sent you a bill from us for the 3 October until the date you moved to a different supplier. This will include any credit balance from Symbio.

  • If you moved directly to E.ON Next we’ll be transferring any credit balance shortly

We're your new energy supplier.

Symbio Energy is no longer trading. Ofgem appointed E.ON Next as your energy supplier from Sunday 3 October.

How do I get independent advice on what’s happened?

For independent advice, you can always check out Ofgem’s website or contact Citizens Advice.

What if I have a query about the meter readings you’ve used?

We worked with Symbio to ensure the meter reading used to open your E.ON Next account was in line with your previous consumption and used actual meter readings wherever possible to make sure you were charged accurately for your energy.

If you do have a query with your transfer meter reading, the best way to handle this is to take a photo of your current meter reading and email it to us at hi@eonnext.com for us to review.
