Thank you for getting in touch.
Your overdraft facility will be handled as a “loan” type debt when in the debt review process. When the bank receives a notification of your application for debt review they will terminate the credit facility and wait to receive a payment proposal.
I would suggest that you open a new bank account with a bank which you do NOT owe any money. Ask the HR department at your work to transfer your salary to the new bank account.
There is a risk that if your salary gets paid into the overdraft account the bank will see it as a payment on the account. We will then have to contact them to negotiate a refund of your salary. By opening a new bank account you will save a lot of trouble admin wise, and in doing so ensure that your salary is safe.
Hope this answer was helpful.
