How do I change Direct Debit details?

It was in his name but now in only mine. 
I am just worried that in the 1st the money won’t come out and I will be in trouble. His name has only just (in the last week) been removed from the account. 

Ah, I see. I’m surprised that they didn’t do the payment change but at the same time. You can check at the point it is due and if not paid put a top-up payment in to keep it right or top-up before and then you have time to sort the account change
 

Hi just want to ask a question so iv had to cancel my direct debit just now as its due on 6th April I forgot to change it till the 12 will I have a problem reseting this direct debit up in 3days time ? 

Hi @Elly , yes 3 days is normally too soon a timescale to get that set and operating. Be careful though as a cancelled dd payment can have an effect on your account. It would be as well to let OVO know - the forum is mainly other customers

OK will I have problem reseting it up though iv never cancel it before it's only because I needed to change it to 12arpril 

You should be able to set it up again. Perhaps take a look here

You can't set up a new direct debit. OVO have to do it so get in touch with them on Monday and they will help.
