I’m afraid you’ll only be able to view the usage for your current meter. More info here: https://forum.ovoenergy.com/my-account-myovo-34/smart-meter-help-how-do-i-see-my-history-564.
Don’t worry though, it doesn’t mean any past history has been deleted. Check out your statements on My OVO to see this: http://ovoener.gy/myovo. If you’d prefer, the Customer Care team will be able to get this for you. Feel free to contact them on Facebook, Twitter or via phone or email. Their contact details can be found here: https://www.ovoenergy.com/ovo-answers#contactnumbers.
I hope you don't mind but I've also edited the title of your topic so that it's more searchable for other users.
