What is a Business Overdraft?

It’s a flexible short-term lending option for businesses.

A Business Overdraft works as a safety net for unexpected expenses. It gives you an extra buffer in those times when you're waiting for payments from customers and might not have enough money in your account to cover incoming expenses.  

Overdraft in detail

Flexible monthly payments

You can reduce your business overdraft by as much or as little as you want each month, with no set minimum pay back each month. 

Borrow up to £50k unsecured (subject to credit approval)

If you have a relationship manager, contact them about your borrowing needs. If you don't have one and wish to borrow up to £50k you can apply online. For more borrowing options, visit our loans page. 

Boost cashflow and only pay interest on what you borrow

If you need help when an unexpected cost comes along, an overdraft is there if you need it. If you don't use your Business Overdraft you won't pay any interest. Simple as that.

Representative EAR

Interest Rate %


Arrangement Fee


Representative EAR (Effective Annual Rate) is used for comparison purposes and shows the annual interest rate we reasonably expect at least 51% of customers who are accepted for and enter into the overdraft agreement to get. It is calculated by using the rate of interest charged if you remained overdrawn for a year, the frequency with which interest is charged, and the effect of compound interest on your debt. The Representative EAR does not include other fees or charges.

81.82% of SME customers who used the eligibility checker received an end quote that was the same, better or no more than 10% above their indicative quote.
