PIP mandatory reconsideration

I had a PIP assessment back in Feb and just received notice (by telephone) that I have been awarded DLA at the standard rate and Mobility at the standard rate. Since I cannot walk 20 Metres I am a little surprised that I did not get the enhanced rate for mobility, I will be starting the mandatory reconsideration as soon as my postal notification arrives. I included both a GP report and a comprehensive report from last December from my WCA Allowance – Limited Capability for Work and Limited Capability for Work Related Activity assessment which was granted.
