I have posted some info on another forum today about Business banking if you run a Ltd company.
Always have a separate and personal bank account from your Business account , and If you have Business Loans / Overdrafts , with your Business bank , don't have your (or your children or Wife's) Mortgage, Pension , Savings, ISA , or any other form of finance with your Business Bank or any other Bank in its Group.
The reason being, if your business go bust , even though you are a Ltd company, and you owe them any outstanding monies they will , can and have done, taken the monies owed to them, from all the other accounts within their banking group, even though they are not part of your business ! However they cannot touch it if its in another Banking Group.
I am talking from experience here, if you have Business Loans / Overdrafts do not use your Business Bank for anything else other than depositing takings , paying suppliers, VAT , wages and any other Business payments only.
Keep CLEAR BLUE WATER between Your Business money and your Personal Finance.
