Credit Check for Current Account

[fairy!]

Do you need a good credit score to open a regular bank account?

[Nether Edge]

Yes, in most cases, but Bank will chiefly consider:
i. absence of bad debts/CCJs;
ii. how many other existing OK debts there are;
iii. whether you are on electoral register; and
iv. your general finances (earnings, regular outgoings, etc.)
