Hi Siobhan
Sorry, I can't stay online long as I'm not too well myself. My advice as a former WRO and DLA Tribunal Member would be to make a claim now.
Full details of how to to do so are
HERE
You can make an online claim, but I personally prefer filling in claim packs in hard copy.
You can get a claim pack by calling the Benefits Enquiry Line on 0800 882200.
When you receive it, check out all the free members guides on DLA
HERE
Good luck.
Jim
