You’ll be able to change the amount you’re paying if you encounter a significant change in your circumstances, like starting a new job and being paid differently as a result, or having a change in the amount of benefit payments you receive.
Changing the amount you’re paying works both ways; you can reduce your DMP payment if you begin receiving less income, but you’ll also be expected to increase it if you begin earning or receiving more money. We can discuss this with you in your annual review.
