Message to All Customers

Symbio Energy is ceasing to trade. Ofgem, the energy regulator, has appointed E.ON Next as the new supplier for its customers.

E.ON Next began supplying energy to all of Symbio Energy’s customers on 3 October 2021.

E.ON Next will contact customers over the coming days and again in a few weeks when the transfer has been completed and their accounts have been fully set up.

Customers don’t need to worry – their supplies are secure. Former and current customers’ credit balances are protected, and E.ON Next will contact customers if they need to determine the amount of any outstanding balance. Domestic customers will also be protected by the energy price cap when being switched to E.ON Next.

Current and former customers who are in debit to Symbio Energy should wait to hear from E.ON Next or Symbio Energy’s administrators who will talk to them about repayment arrangements.

Ofgem’s advice to Symbio Energy’s customers is not to switch, but to sit tight and wait until E.ON Next has been in touch. This will help make sure that the process of handing customers over to E.ON Next and honouring any credit balances is as hassle free for customers as possible.

A supplier’s fuel mix shows the sources of the electricity that it supplies to its customers e.g. coal, gas, nuclear and renewables.

Over the course of a year, energy suppliers must purchase sufficient electricity to feed into the national electricity grid to cover the amount their customers consume. At the end of each year, suppliers must disclose their fuel mix to the electricity and gas regulator, Ofgem. This information is published annually to help consumers make informed choices about their electricity supplier.
