I have a personal account with the Co-op. I pay in a few cheques per month, for which no charges are made. Works well enough for me.
I used to be with the Halifax, who once buttonholed me to open a business account while I was in the bank. They sat me down to sell me the benefits of having such an account. I explained that my credit rating was poor, so I didn't believe they could help, but they said they would check to see what they could do. Half an hour later, they came back with the news ... 'Sorry, your credit rating is not good enough!'
As I am a sole trader, I keep scrupulous records, so I don't see the need, especially as I can't get a business account anyway!
John.
