Pip award successful without a review

Having endured the change over fro.dla to pip I was awarded 3 years. I was reviewed again in December 2016 and once again awarded 3 years. I was awaiting a further review any day now and had prepared, including another letter from my gp. I got the biggest surprise this morning, a letter from DWP, Ithought it was my review forms, you can imagine my shock when I opened it to see it was an award letter for an ongoing period and they won't bother me untill 2029. Both at enhanced rate.

I wonder how this happened without any form filling, sending evidence or eview of any sort.
I feel so liberated and content, I will be in my 70s when they contact me.

I can only think that with my review coming up they must be looking over previous information and making decisions rather than putting folk through the stress of a reassessment, maybe things are changing for the better. The only thing that changed for me was the length of the award as I was always enhanced. It really does enforce the need for good solid evidence of your illness/ disability being sent to DWP. This, I hope. Will maybe offer hope to many out there.

Yes but this was done before any review procedure being initiated, they must be looking at people due a review and giving out awards instead of starting the review, I have never heard of this before, have you?
