"Where can I get help filling out my PIP claim form?
You can find a very helpful question-by-question guide to filling in your PIP claim form on the Citizens Advice website.
Your nearest Citizens Advice Bureau should also be able to provide you with PIP advice and guidance on filling out the form.
Check Scope’s Services Directory to see if there is a local information and advice service which can assist you with the form-filling.
If you cannot complete the form in time call the PIP claim line as soon as possible and ask for an extension."
I hope this helps. Others will, I am sure, respond to your post soon.
Warmest best wishes to you
