PIP claimants survey to detail disability costs?

Hello

I was reading the news on the internet and came across this story (I normally ignor these types of stories) and it caught my interest. My brother claims PIP so it could impact him. The article in question can be found here www.birminghammail.co.uk/news/cost-of-li...ility-costs-30228211

Quote:-
"Sir Stephen Timms, Minister of State for Social Security and Disability, says the Department is now conducting a new survey of PIP claimants to learn more about their disability needs and expenses. The study, which will look at the reasons people require financial support from PIP payments, comes ahead of new reforms to disability benefits that are due to be announced in spring 2025.

The minister shared news of the survey following a written question by Neil Duncan-Jordan (Labour, Poole), who asked what assessment the new Work and Pensions Secretary, Liz Kendall, had made of the "adequacy of Personal Independence Payments at supporting the extra costs of disability." "

My question is does your back team know anything about this new survey to be conducted by the Government of PIP claimants and will this survey be a voluntary survey or will it be mandatory for all PIP claimants to fill it in?

Thank you in advance for your assistance.
