I can see you’ve PM’d me about this, and I’ve replied with some good news. I'm sure you won't mind that I've made this topic more searchable by editing the title and adding some tags.
As for anyone else, you’ll be able to adjust your Direct Debit via the app and My OVO page. We will have a recommended figure which will be the minimum amount possible, and a maximum amount that you can set it at. How we calculate this recommended Direct Debit is explained here: https://www.ovoenergy.com/ovo-answers/topics/payments-and-statements/payments/how-did-you-work-out-my-new-direct-debit-amount.html.
If you do have issues changing the Direct Debit within this minimum/maximum range, drop us an email at: email@example.com or message the team on Facebook or Twitter.
