Reporting changes to finances - LCRWA and UC

Hi all,

I am really confused about what is expected of me having migrated to UC around 3 months ago.

I have been claiming ESA for many years, after being placed in the Support Group. Insofar as I know, I never had to report changes to my finances unless I went over the savings limit, my rent increased or I changed banks.

I am very concerned that the situation is now different in regards to UC, although I remain in the LCWRA group. Do I need to declare any changes in my finances every month, such as unspent benefits, even if I am under the capital limits? If so, how do they expect very poorly people to do that, and for what purpose? Surely unspent benefits are not significant if one is below the capital limit?
