How to Switch from E.ON to Octopus Energy
Thinking about switching your energy supply from E.ON to Octopus Energy? Here is what you need to know about transferring your smart meter and how it could affect your billing and usage tracking.
Before you switch
Check your contract end date with E.ON, as leaving early from a fixed-term deal may mean paying an exit fee, usually between £30 and £60 per fuel type. Review your E.ON contract or contact their customer service to confirm if any exit fees apply. You will not lose your email address, phone number, or any bundled broadband services, as these are not linked to your energy account with E.ON.
How to switch, step by step
- Get a quote from Octopus Energy. Visit the Octopus Energy website and enter your postcode and energy usage details to receive a personalised quote.
- Sign up with Octopus Energy. Provide your household details, meter information, and payment preferences to start the switch.
- Let Octopus Energy handle the switch. Octopus will notify E.ON and manage the entire process for you. You do not need to contact E.ON directly.
- Submit a final meter reading. Octopus will request this to ensure your final E.ON bill is accurate and your new billing starts correctly.
- Wait for the switch to complete. The process typically takes up to five working days. Your energy supply will not be interrupted at any point.
What to watch out for
- Exit fees: If you are still within a fixed-term contract with E.ON, check for any early termination charges before switching.
- Accurate meter readings: To avoid billing discrepancies, provide an up-to-date meter reading when requested by Octopus Energy.
- Smart meter compatibility: Most E.ON smart meters (SMETS2) work seamlessly with Octopus, but if you have an older SMETS1 meter, check with Octopus to confirm compatibility and continued smart functionality.
