WRAG time limit

I am currently in the Contribution based Support Group, but am still awaiting the result of my case review, ESA50 sent back 20th February. If I were to be transferred to the WRAG, what happens after 12 months? do you then automatically get transferred on to Contribution based Job Seekers Allowance, as I won't qualify for Income Based ESA, or do you just get nothing after the one year has lapsed.

No, once your time on CBESA is up, you won't get CBJSA, you will only get benefits if you're entitled to Income Based benefits, be that JSA or ESA.

CBJSA has a six-month time limit.
