You can continue to top up with OVO right up until your change of supply date. Once you’ve changed supplier, if there’s credit on your meter we’ll contact you about a refund. If you have a smart meter, we'll switch it to credit mode before you switch to avoid you going off supply.
If you want more information on your meter, we have a range of guides. Find out how to top-up, turn your meter back on afterwards, activate emergency credit and troubleshooting tips.
