If you prepare well, learn the rules, fill in the form in such a way that you are explaining exactly how you meet the descriptors and provide evidence to support your claim, it’s possible. You could of course see if you can get help from the CAB or another welfare rights adviser. But if that’s not possible, take your time and do the best you can.
Think about joining https://www.benefitsandwork.co.uk/ if you haven’t already. Their guides for members are excellent and will help you through the form.
I actually did get a care assessment from social services, which I was hoping to use in my PIP claim, but it was dreadful. Badly written, a bit confusing, didn’t really represent my situation and called my husband by the right name at first, then changed it halfway through and called him something else. I decided not to use it.
And I still got the award, enhanced for both components. (Without a face to face assessment.)
You can use letters from your MS nurse, neurologist, physiotherapist, bowel and bladder nurse, your carer (it doesn’t matter if that’s your partner, it is still evidence). I also attached a list of exactly what evidence I’d provided and what that evidence demonstrated in terms of care needs and mobility.
So yes, it’s possible, it just takes time and effort. I know that’s easy to say and hard to do, but you just stagger it. So you do a bit, then stop. The next day you do a bit more, etc. And if you write the answers to each section in a draft form first, you can then read them back and make sure you have stated exactly what care and mobility problems you have. You have a month, so use the time to make the best claim you can. Just make sure you photocopy everything and send the claim recorded delivery.
All the very best of luck.
