UK High Street Bank

Hi, do you guys know any workarounds for UK High street banks for people like us? I need specifically a real bank for my trips and plans I’m well aware of how monzo, n26, tw work, I’m just not interested in those mobile banks. Every UK bank needs proof of address if I am to sign up there and I’ve got none in the UK… what can I do to get one? Any loopholes?

I set up a guy last year so he could get UK bank account/ NI number etc…worked out well.
