It’s likely that you have smart meters that communicate with OVO every half an hour. This ‘half hourly settlement’ is recorded on the database (ECOES) as profile class 0, which some suppliers think is a commercial supply.
In these instances we can update the profile class to 1 to enable the incoming supplier to take it over. You’ll need to get the support team on this: We’re on Facebook, Twitter and our Help Centre has online chat!
