Go to the portal
Open the E.ON Business business customer portal at the link above. Bookmark it so you do not waste time searching every month.

Enter your credentials
Your username is usually the email address you registered with. The password was either set during your first invoice or sent in a welcome email.

Confirm the right account
If your business has multiple sites or meters, the portal will ask you which account you want to manage on the next screen. Pick the right MPAN or MPRN before submitting any meter reading.
Troubleshooting
Can't sign in? Four common fixes
Most E.ON login problems fall into one of four categories. Try the matching fix below before calling the support line.
Forgot password
Use the E.ON Business 'forgot password' link on the login page. The reset email lands within 10 minutes,check your spam folder if you cannot see it.
Locked account
After five failed attempts most portals auto-lock the account for 15-30 minutes. Wait the cooldown out rather than retrying instantly; repeated failed attempts can extend the lockout.
Account number mismatch
If the portal rejects your account number, check whether E.ON Business has merged or rebranded since you signed up,your new account number may be on a recent invoice.
Cannot find login email
Search your inbox for 'E.ON' plus the word 'welcome' or 'activation'. If still nothing, the registration may not have completed,call the support number below.
