The statements will come out on the same day each month, however if this falls on a weekend, it'll come out on the following Monday, so it's not generated when you input your meter readings. There's a few reasons why you may not receive a statement, the main one being if you've had a new meter fitted. We put you on a billing suspension for 6 weeks, so that we can get the relevant info about your old meter, and your new meter, and then bill you for the full 6 weeks.
It could also be if we create a 'read dispute', which is when the readings don't seem to fall in line with your previous usage. Further info on this subject here: https://www.ovoenergy.com/guides/energy-guides/guide-to-meter-reading-disputes.html
It'd be best to get in touch with the team, though, as they'll be able to see exactly what the issue is, and if needs be, generate a statement then and there. You could drop us an email at firstname.lastname@example.org, or if you'd prefer, send us a message to our Facebook or Twitter pages: https://www.facebook.com/ovoenergy or https://twitter.com/OVOEnergy.
