Being in a DMP will more than likely affect your credit file and score. This is because you could be paying less than a creditor’s requested minimum payment amount.
There isn’t a specific place in your credit report to register that you are on a DMP, but the debts that are included can have a marker added to show that you are making payments through one. This may reduce your chances of obtaining credit whilst in your arrangement, as it shows that you are having difficulty keeping up with repayments.
However, a DMP does look better on your credit file than having unpaid debts and defaults showing.
