Business Overdraft vs Business Credit Card UK 2026
A business overdraft is an arranged buffer attached to your business current account, letting the balance dip below zero up to an agreed limit, useful for smoothing day-to-day cash flow gaps such as waiting for invoices to be paid. A business credit card gives a separate revolving credit line, often with better expense tracking, employee cards, and sometimes rewards, but usually a shorter interest-free period if not paid off in full.

Frequently Asked Questions
Is a business overdraft or credit card cheaper?
It depends on how you use each: an overdraft charges interest daily on whatever balance is overdrawn, which can be cheaper for short, small dips in cash flow, while a credit card is effectively free if paid off in full within the interest-free period, but expensive (often 20%+ APR) if you carry a balance month to month.
Can I get a business overdraft with bad credit?
It is harder — banks assess business overdrafts based on your trading history, cash flow and credit score, so newer businesses or those with credit issues may be declined or offered a smaller limit than requested. A business credit card from a specialist provider may be more accessible in this situation, though often at a higher interest rate.
Do business credit cards affect my personal credit score?
For sole traders, business credit cards are often linked to personal credit and can affect your personal score, since sole traders are not a separate legal entity. Limited company credit cards are usually assessed on the company's credit profile and a personal guarantee from the director, which can still indirectly affect your personal credit if the guarantee is called upon.

Can I use an overdraft and a credit card at the same time?
Yes — many businesses use both: an overdraft as a safety net for unpredictable cash flow timing, and a credit card for day-to-day spending and expense management, since they serve different purposes and using both correctly can improve overall cash flow control.
What happens if I go over my agreed overdraft limit?
Exceeding an agreed overdraft limit typically triggers a higher "unarranged overdraft" interest rate and can incur additional fees, and repeated occurrences may lead your bank to reduce or withdraw the facility at review, so it is important to monitor your balance closely if you are near the limit.
