Confused !

I have fibromyalgia, osteoarthritis,depression and anxiety. I have been on ICB since finishing work in 2005 and DLA lower rate since 2008. I filled in the ESA forms and I have been put into the wrag group and awarded contribution based esa. I was very surprised to receive the letter without having to attend a medical, extremely relieved as I was in a really bad way mentally from just filling in the forms. As my husband works, will I get this for one year regardless of his earnings? I would not get anything if they take his earnings into account so I think I am going to appeal to try and get in the support group. Is it possible to be transferred from wrag to support group in the coming year if i don't appeal now?

Thank you. I have looked at the guides and think I would have ESA from the award date 27/12/2011-27/12/2012, is that correct? My decision letter is dated 1st December which means I would have to appeal over the xmas period so I am thinking to ask for the decision to be reviewed and sending in more evidence as I cannot face filling more forms in, and could still appeal from the new decision date. Is that also correct?

Ok, does the time matter if I'm still getting the money for a year anyway and can I send additional evidence with both a reconsideration request or a GL24 form?
