Query re. UC and increase in housing costs

Hi,

I receive the housing element of UC (LCWRA) and have been notified that my rent will be increasing later this year.
I tried to inform UC/DWP of this via my journal and began the change of circumstances option relating to housing .
When I entered the start date of the change, I was prompted that a future date could not be entered.
I wasn't sure what to do and cancelled the change, thinking that I would need to wait to fill out the online form.

My journal now has a "Where you live and what it costs cancelled" message added by me. I am worried that this entry will affect my UC claim (I was migrated over from ESA and am still unsure how to do things).

Please can you advise me when/how to update UC/DWP regarding the increase in my housing costs?
Also, do I need to contact DWP to explain the journal message?

Thanks for any advice that you can give me.

Hi,

Please can you advise me how to make a note on the UC journal?

I had meant to do that but there did not seem to be a way to make a note, so I began the change of circumstances option relating to housing. (Sorry for the basic question, I am worried about trying to add anything now).

Thanks for your help.
