Hi NTCohen
It's a review form you're completing. People put in for a change of circumstances when they want to alert the authorities to a change in their condition, generally in the hope that they can receive a higher award.
The advice to ADP claimants is the same as PIP claimants in terms of ticking 'no change' on a form. Claimants have to do what is best for them at the time of completing the form. If possible we suggest that even if you are saying there is no change - you still repeat what hasn't changed. See page 132 and 133 of the Guide to PIP Claims and Reviews
benefitsandwork.co.uk/guides-for-claimants/pip It is not true that claimants have their awards withdrawn if they just tick 'no change'.
