Migration from ESA (SG) to UC query

Hello, I am seeking some guidance on the following matter:

I have received my migration letter with a deadline of April 10th, and I plan to submit my UC application on April 9th. If there are no changes to my circumstances, I should be eligible for the transitional protection payment. I recently changed my phone number and want to update ESA with this new number before making my claim for UC as this is the number I would be using when making my claim for UC. Would this be considered a change of circumstances that could affect my eligibility for the transitional protection payment?

In addition, I have limited mobility and struggle with depression and anxiety. I understand that I will need to verify my ID online when applying for UC. Will I still need to visit the job center even after verifying my identity online? As I would struggle with this.

Any advice on these matters would be greatly appreciated.

Thank you David for your response.

I did call the UC migration line to ask for guidance on my struggles with attending the job centre once I submit my claim and verify my ID online. I was told after submitting the claim to add a note in the journal section to explain my difficulties if asked to attend the job centre. I’m a bit confused why you would need to attend the job centre if you are able to supply the required during the application process.
