Migration from ESA to UC

Finally did the migration today. Had a charity support worker help me.
What an absolute nightmare. 3 hrs it took, I ended up crying with the confusion of it.
And still not finished as couldnt complete ID Proof, one question was about addresses where I lived & never heard of them & no option to say none.

So both myself & husband have a "biographic" I think its called, telephone call next Weds. Me at 2.15pm & him at 2.50pm.

The support worker rung the Help to Claim line for advice of what would be needed during these calls & she was told the same questions as online. So if we both failed those, then surely we'll fail again. We cant get into a job centre due to our illnesses.

Has anyone had one of these calls & if so what are you asked? There is a list online says birth certs, tenancy agreements etc how do you show those down a phone. Plus we both suffer with brain fog, my husband more so due to cancer.

I've literally collated every piece of paperwork over 3 months & still not done with the migration.

No idea of next payments etc completely in limbo.
In hindsight I wish I had pushed for a home visit, as today as been a nightmare.

Any advice re these calls next Weds would be appreciated as we are both totally confused, stressed & tired.
Thank you

I had a biographical phone call to verify my ID. The man I spoke to was lovely and really kind. You don’t need any documents, they just ask questions that you will know the answers to but other people wouldn’t.
