Becoming appointee for your brother is a big responsibility – it’s not just about helping him to manage his welfare benefit money but also making sure he is claiming everything he is entitled to. I work for Mencap’s information and advice team and family members often say the same – that they are worried about the responsibility and want to make sure they are doing the right thing for their loved one.
There is information about being an appointee on this link: https://www.gov.uk/become-appointee-for-someone-claiming-benefits
If you want a quick way to check what your brother might be entitled to, there is a benefits calculator on the Turn2Us website: https://www.turn2us.org.uk/
It might be a good idea to ask for some face to face advice. Your local Citizen’s Advice Bureau will have specialist advisors who will be able to do a ‘better off’ calculation to check that your brother is claiming everything he is entitled to. They may be able to help with filling in claim forms too.
Finally, your brother can reapply for PIP and start the process again, but he would need to show that something has changed since he was turned down last October.

All the best,
