I think I know what’s probably happening here. It’s worth noting that unlike other suppliers, OVO has the billing platform set up to do real-time balance updates whereas most other suppliers only update the balance after you make a payment, get a refund or a bill is generated. This might explain the discrepancy you’re seeing - don’t forget to check the Billing History tab as well, since this has a lot of transparency as to exactly what’s happening at any given time.
The following events (among others) can cause your balance to increase:
- Top-Up Payments
- Monthly Direct Debits
- Warm Home Discount
- Billing corrections to fix overpayments
- Manual corrections by OVO’s Support Team
- Manual intervention by OVO
- Reimbursements (such as after a complaint is resolved)
- Guaranteed Service Standards
- Or as required by the terms of your contract
The following events (among others) can cause your balance to decrease immediately upon triggering:
- Meter Readings of any kind - including Estimated, Manual, Smart or via the Support Team
- Daily Standing Charges
- Bill generation
- Add-Ons like OVO Foundation or OVO Beyond (exception: OVO Drive Anytime, which is a free add-on)
- Refunds - but these will go back to your bank account
- Failed payments (like a bounced Direct Debit)
- Billing corrections
- Charges
- Manual intervention by OVO - only used if absolutely necessary
I hope this helps. Please let the Support Team know if you still think some of your account balance is missing and they’ll be happy to investigate.
