Review date calculation

I have heard by letter that I have been placed in the support group rather than the WRAG, which it was suggested by phone that I would be placed in. I am very releived as this feels the right decision for now. I know that in the future there will be a review but I am wondering if anyone knows what point in the process the review is caluclated from. Is it from when I was intially contacted before Xmas 2011, the date I got my decision, May 1st 2012 or the date of the first payment of ESA, June 7th 2012?

Thank you by the way for the terrific support this web site gives. The whole process is anxiety provoking and isolating and without your excellant advice and information, I'd be very lost with out it.

Hiya,
I was first placed in the WRAG group in Dec 2011, sent a letter in for appeal and was later looked at by a DM and finally placed in SG where it should have been, and for 18 months as listed on my med form, moreover it was backdated to DEC 2011.As the way seems to be ,a review is likely to be in 16 months time from Dec 2011. Hope that answers your question.
