UK limited company and personal bank account 
I don't think there is a legal requirement that you need a separate bank account. Just remember that you can only take money from your LLC as salary (paying tax), as dividend (paying tax), or as a loan (which you need to repay, including and especially if the LLC goes bankrupt). So make very sure that your books are in order.
