Companies of all types rely on business credit cards to manage expenses, earn rewards, and provide a financial cushion for unexpected events. However, not all credit cards are created equal—if your business requires significant spending power, a high limit business credit card can make all the difference. 

It’s worth noting, however, that they also bring their own considerations when it comes to application and usage.

What are high limit business credit cards?

While most credit cards are designed for more modest financial management, that’s not the case for all of them. High limit business credit cards offer credit lines designed to support larger purchases, from bulk inventory orders to major equipment upgrades. 

While there’s no universal threshold defining "high limit", these cards typically offer credit lines starting at £10,000 and can go as high as £250,000 or more, depending on the provider and your business’s financial profile​​.

However, since these are by nature a riskier product, lenders tend to be much more selective when it comes to applications – and if you’re a new business or one with a patchy credit history, you might be better off applying for a standard credit card and building your credit profile from there.

How are credit limits determined?

When you apply for a credit card, the lender will look at your business’s financial background, including your trading history, turnover and profit, to try and work out how risky it would be to lend to you. 

While credit limits on business credit cards tend to be higher than credit limits for personal credit cards, the actual figures vary widely and depend on factors such as:

  1. Business revenue: Higher annual revenue typically leads to higher credit limits.
  2. Credit history: Strong personal and business credit scores demonstrate reliability to lenders that you can service the debt. 
  3. Cash flow: Providers often assess your ability to manage large repayments – such as those you might incur on a high limit business credit card.
  4. Time in business: Established businesses with proven track records may qualify for higher limits​​, since they have shown the ability to sustain themselves.

It’s worth noting that credit limits are not a one-and-done enterprise. Once you have had a credit card with a provider for some time, meeting payments regularly, they may well increase your limit. If you have a moderately healthy business financial history, you’ll likely be offered between £1,000 and £10,000, but this can rise up to five times with a better history.

What are the benefits of high limit business credit cards

1. Improved cash flow management

High limits allow businesses to cover significant expenses without affecting cash reserves.

2. Earning rewards on large purchases

Many high limit cards offer cashback or points for spending, maximising returns on business expenses.

3. Expense tracking and employee cards

These cards often come with robust tools for tracking spending, issuing employee cards, and setting limits.

What are the risks of high limit business credit cards

While high limit business credit cards can be strategically beneficial, they also come with potential risks that you should definitely think through before applying.

1. Increased debt risk

High credit limits make it easier to accumulate significant debt, especially if spending isn’t carefully managed. Without a clear repayment strategy, your business could struggle to cover monthly payments, leading to financial difficulties.

2. Impact on personal liability

Many high limit cards require a personal guarantee, which means you’re personally liable for the debt if your business cannot repay it. This could put personal assets, such as your home or savings, at risk if the business faces financial difficulties​.

3. High interest rates

Carrying a balance on a high limit card can result in substantial interest charges, particularly on cards with variable APRs. This can quickly escalate borrowing costs, eroding any benefits from rewards or cashback.

4. Approval challenges

Securing a high limit card often requires excellent credit scores, strong financial documentation, and significant business revenue. Without these, your application could be denied, potentially impacting your credit score​.

5. Employee misuse

If employee cards are issued, there’s a risk of misuse or unauthorised spending. Businesses need strict oversight and controls to mitigate this risk.
