From PIP's introduction in NI on 20/6/16 up to 31/5/18 out of the 26,520 MR's cleared 5800 resulted in a new decision. This information was provided by the DfC and to save you getting the calculator out that is 22%.I can't say if they were all successful. I asked for feedback from a Disability page and 1 person came forward to say her MR was successful with the help of her GP.
