Re applying for pip

Only if you currently have no PIP award. If you have an existing award and are appealing to try and get a higher award then you will not be able to make a new claim.

However, as Mike says, a new claim will limit the result of the tribunal to the period from the date of the original claim to the date of the new claim. That might make sense if you have had a significant change in condition which means that a new claim is more clear cut.

Can someone make a new claim for pip if awaiting a MR decision? Or only if tribunal is happening?
