Hi Claire1985,
Welcome to the forum.
Usually with these, you keep submitting your fitnotes to the DWP, and then they'll send you a UC50 form to which you'll fill in, and then have an appt with an HCP.
I'm assuming you've already been given the award of LCWRA ? If so, It's usually from what I remember, the first 3 months are disregarded before you'll be given an extra £390 approx on top of the standard Universal Credit award, which the amount differs based on your age, and relationship status if single or living as a couple.
Hope this helps, any further info, just reply back, and myself or one of the other mods will do our utmost to try assist you.
Regards, Chris.
