Regarding PIP and other ‘benefit’ claims, I recommend going to the website:
They are brilliant in my opinion. They provide resources to help you make the best application possible. There are some free resources but I strongly recommend paying the reasonable membership to get access to the very in-depth PIP guides and all other benefits guides. There’s also forums as well for asking questions.
Hope this helps someone out there struggling with all those forms and questions, as it has really helped me with my claims.
