The exact time window varies depending on your energy supplier, where you live, and other factors. But generally, the 7 off-peak hours fall somewhere between 10pm and 8.30am. (Remember, this can change with British Summer Time).
I am not looking for a 'general' idea of what time OVO E7 hours are. I am looking, and have been looking for exactly what those hours are. This information seems to have been deliberately hidden from both the public, and your customers.
Is this hidden so well for any particular reason? Is it something they vary regionally, or from day to day?

When are my peak/off peak hours?
If you have a Smart meter installed by OVO, the off-peak times can be worked out using your Meter Point Administration Number (MPAN). You can find your MPAN on the ‘Plan’ page of your online account or OVO app (download for Android or iOS).
Then use this table below; the first two digits of your MPAN is the ‘Area ID’; the ‘Off peak’ times are on the column second from the right:
Please be advised that Secure, Aclara and Honeywell smart meters don't adjust for British Summertime. This means during summer your off peak times will be an hour later than advised above.
If you have traditional meters or smart meters that were not installed by OVO, the off-peak hours may vary. The best way to find out in this case would be reaching out to your supplier (or our Support Team if you’re an OVO member).
You don't. They are set by a combination of region and supplier. It's seven hours of lower cost electricity usually starting from either 11pm or midnight. Your electricity bill should show the times for peak and off-peak and the rates for each.
If you think the meter isn’t switching at the times it’s supposed to then that is definitely in-scope for a closer look. Please bear in mind there is a random offset/delay of up to 30 minutes to avoid the national grid blowing up but if you’re seeing things happen massively outside of those times and it’s not because of GMT/BST differences, your supplier can help.
Suppliers can force the meter to refresh the times to match what they’re supposed to be, though they’re only allowed to refresh them to what is allowed for your area.
If you’re with OVO, get in touch with the Support Team later this week (please avoid this Tuesday!) and they’ll take a look - otherwise please ask the customer service of your supplier.
I see that @Peter E has done a fantastic job answering your question and letting you know that the times are pre-set and can't be adjusted. I’d love to understand why you’re asking about setting the times. Are you looking to change them, or have they stopped working for you and you want to set them up again? I've included a link below with more info on how to find your times based on your MPAN number. Hope this helps!
