Uc migration

Hi I have tried to work out calculations over and over again but keep coming out with 0 on uc when I am forced migrated over to uc from ctc. We are carers for our children and husband earns a pension that pension is taken pound for pound from the end figure plus our carers allowance Is also pound for pound. These two things wipe the whole award out. ( I included all elements. Couple/carers elements/ child and disabled )

I also don’t think we will get transitional protection as in theory before deductions we get more on uc than ctc. Can I ask anything I can do if I go from £159 a week on legacy ctc to 0 on uc? It seems we are in a weird position for universal credit and am wondering if I can get advise anywhere.
