High limit business credit cards UK

If you're managing large amounts of business spending, a standard credit card limit won't cut it. You need access to a lot of credit, ideally £100,000 or more. The question is: which card offers the highest limit, the best features, and the right fit for your situation?

This guide compares the top high-limit business credit cards available in the UK, explains how limits work, and shows you how to improve your chances of qualifying for one.

What counts as a high credit limit for a business?

"High limit" is relative. For a sole trader, £10,000 might feel generous. For a mid-sized company, £100,000 is just the starting point. For larger operations, £250,000+ is the baseline.

In the UK market, cards offering limits above £50,000 are considered high-limit. Most traditional business credit cards max out at £25,000-£50,000, so anything much higher sets these products apart.

The highest available limits in the market currently reach £250,000, which covers everything except the largest corporate spending.

Top high limit business credit cards

Funding Circle Cashback Card

Limit: Up to £250,000

Annual fee: None

Cashback: 2% for first 6 months (up to £2,000), then 1% uncapped

Interest: From 14.9% APR

The Funding Circle Cashback Card is built for UK businesses that want to earn on large spending without paying for the privilege. At £250,000, it offers one of the highest limits available on any UK business cashback card. The 2% introductory rate is competitive, and dropping to 1% uncapped means it pays for itself across ongoing spend.

There is no hidden fee; no annual fee, no FX fees, no early repayment penalties on the cashback. For businesses managing substantial monthly outgoings, this combination of high limit and no-fee structure is hard to beat. The main consideration is interest on carried balances, which runs at 14.9% APR.

Before choosing a card, it helps to understand what is cashback for business and how returns compare across providers.

Capital on Tap Business Credit Card

Limit: Up to £250,000

Annual fee: £0 on the Standard tier; £299/year for the Pro tier.

Cashback: Uncapped 1% cashback on standard card spending. The Pro tier unlocks 1.25% on preloaded spend.

Interest: From 13.86% APR

Capital on Tap focuses on high-limit access without annual fees on standard accounts although there's a £299/year fee for the Pro tier. The cashback structure is flexible, and the interest rate is slightly better than some competitors.

The main advantage is straightforward lending, they're known for accessible approval processes. If you need quick access to a high limit without extensive credit checks, this is worth considering.

American Express Business Platinum

Limit: Variable (depending on your business profile)

Annual fee: £650

Rewards: Membership Rewards points (not cashback)

Interest: 29.1% p.a. (variable) (applies if you choose to use a line of credit via Flexible Payment Option).

Amex Platinum targets established businesses willing to pay for premium features. The spending limit is flexible and adjusts dynamically based on your business’s financial profile, spending patterns, and payment history. A points-based rewards system offers flexibility (you can convert to travel, cash, or transfers).

The £650 annual fee is more than other providers, so you need sustained high spend to make it worthwhile. The card suits businesses that value premium benefits (airport lounges, travel insurance, concierge services) beyond just the limit itself.

Payhawk

Limit: Up to £500,000

Annual fee: None

Format: Corporate/expense management card

Features: Real-time expense tracking, multi-card issuing

Payhawk is less a traditional credit card and more an expense management platform with high credit limits. It's designed for teams, not individual cardholders - you can issue cards to employees and track spend in real-time.

If your business needs corporate card control and transparency (see who's spending what, on what, instantly), Payhawk's £500,000 limit combined with administrative features justifies the approach. It's not ideal for simple cashback seeking, but for larger operations needing expense oversight, it's attractive.

How is your credit limit determined?

Your business credit limit depends on several factors. Understanding them improves your chances of qualifying for (and keeping) a high limit.

• Your business credit score. Just like personal credit, businesses have credit scores. These reflect your payment history, how long you've been trading, and whether you've defaulted on debts. Building a strong business credit score improves your chances of qualifying for a higher limit.
• Your turnover and profitability. Card issuers want evidence that your business can service the debt. They'll ask about annual turnover and profit margins. Higher turnover generally qualifies you for higher limits.
• How long you've been trading. Established businesses (typically 2+ years) qualify for higher limits than startups. This is because trading history demonstrates you've survived and managed finances.
• Personal guarantee and assets. For high limits, issuers often require a personal guarantee (the director is personally liable if the business can't pay). They may also check your personal credit score and assets.

Be aware that this is not an exhaustive list and each provider will use a different approach to approving credit limits. Check your eligibility before applying.…

How to get a higher business credit card limit

If your current limit isn't satisfactory, here's what to do.

• Request an increase directly. Many card issuers will increase your limit if you ask and you've been a good customer (paid on time, consistently used the card).
• Improve your business credit score. Pay all invoices on time, clear any business debts, and maintain regular trading activity. Your score will improve over months, opening doors to better limits.
• Build personal wealth. Since many issuers require a personal guarantee, improving your personal credit score and accumulating personal assets (property, savings) strengthens your application.
• Switch to a higher-limit card. If your current provider won't increase your limit, apply for a new card with a higher baseline. You'll go through a full application, but access to new products is sometimes faster than convincing your existing provider to increase yours.
• Trade longer. If you're in the first 2 years of business, be patient. Most issuers will automatically increase your limits once you hit the 2-year mark and demonstrate stable trading.

FAQs

What is the highest business credit card limit available in the UK?

Currently, £500,000 is the highest available on any UK business credit card although £250,000 is most common and more accessible. For most mid-market businesses, this covers routine spending entirely.

Can a startup get a high limit business credit card?

It's possible but unlikely. Most issuers prefer 2+ years of trading history. Startups typically qualify for limits of £5,000-£25,000 initially. Once you've hit the 2-year mark, reapply – your limit will likely jump significantly.

Does applying for a high limit credit card affect my credit score?

Yes, temporarily. Each application creates a hard inquiry on your credit file, which can lower your score slightly. Multiple applications within a short period have a bigger impact. Space applications out by at least a few months if possible.
