Direct Debits
We’re making a small change to our banking and the way we collect Direct Debit payments. We’re now combining Direct Debits that are paid on the same date and taking payments under a different reference number, but it will still be O2. Making things simpler for you and for us.
We’ve changed some of our banking details, so you’ll see a new Service User Number (SUN) and a new Direct Debit Reference Number. Don’t worry, this won’t affect how much you pay each month (terms apply), it’s just to let you know that we’ve changed some of our banking details and we need to send you a new reference number.
No, don’t worry, your Direct Debit payment date will stay the same.
No, your regular payments and the service you receive from us will carry on as normal.
You don’t need to do a thing. We’ve told your bank/building society about the change, so they may get in touch with you.
You’ll see that a new Direct Debit has been set up with a new reference:
Service User Number: 188911
Direct Debit Reference Number: [DD Reference] CF2
You may notice your bank/building society statement has a comment about a ‘final payment’ under our original bank details, and a ‘first payment’ under our bank new details.
You can call us on 202 (free from your O2 mobile) or contact your bank/building society. You’ll need to quote O2 and have your account number/DD reference handy.
You’ll be glad to know that you can continue to enjoy the full benefits of the Direct Debit Guarantee
