Just a quick update:

We got some proofs of address:

1) School admission letter from the council
2) I was able to get a second credit card issued, in her name (only found that option when going through the T&C for the card)*

With both we went to the GP who started the registration process (we did phone several GPs near us, all wanted POA before registering us).


@sars_notd_virus: You don't need a NI number to apply for jobs, your employer can arrange that for you (that's how I got mine back in the day, and the government website still confirm that). There might be some employers who can't be bothered or don't know, though.


* It's weird that one can order a second credit card for an existing account just so, without any PoA asked, while so many other things (with potentially less impact) need a PoA.
