rent

at the moment my rent is paid via UC
but what would happen if was to tell UC i will pay the rent
will they then pay this in to my account
standard allowance is £400.14
i get limited capacity
i get small amount of transitional
will the transitional go up
limited capability go up
before my rent was paid via UC to housing association the transitional was higher

I know that because i get 6 weeks free rent UC is calculated at 46 weeks
but is it true that UC issue 12 rent payments from 1st April till 31 march
thank you
