Re-read my question and it did read a bit like I was having ago, wasn't meant to.
I'm just used to every invoice, cash or cheque, going into the business account. I do have an accountant to keep happy and she has an legal duty (on pain of death) to report the accounts properly. If you take money out of the business, normally, you have to show from where it came.
Your accounts are none of my business and I'm not trying to lecture, but in case you get investigated by the revenue it's best to keep every thing above board.
