I dont understand what you mean re the paying your salary into?
And yes I’ve seen those posts about accounts being closed down… so scary!
Sorry, that was bit cryptic!
I bank cash in a personal 'work' account, transfer it to my business account and pay myself a regular salary every month from there; this appears on my personal 'personal' account and can be helpful for things like renting (I moved home not long ago, and it definitely didn't hurt then). I pay all work costs and bills from the work one, and personal stuff from the personal one and that makes it easier for doing accounts and so on.
Looking flawless on paper is never a bad thing, plus having a regular set amount of money coming in helps me not be silly with it
