Best Business Credit Cards for UK Small Businesses

The best business credit card depends on how your business spends, not one universal answer. This guide compares nine UK business credit cards, including the Capital on Tap Business Credit Card, on fees, cashback, representative APR, credit limits and eligibility, so you can match the right card to how your business actually operates.

Why the right business credit card matters

A business credit card does more than separate business spending from personal accounts. Used properly, it smooths out cash flow between invoices, gives each employee their own card and spending limit rather than one shared card or a pile of expense claims, and turns routine spending into cashback you'd otherwise miss. Pick the wrong one, though, and you end up paying for it in annual fees, foreign transaction charges, or a representative APR that only makes sense if you clear the balance every month.

A business spending heavily overseas cares about foreign exchange fees in a way a business that never leaves the UK doesn't, and a business with a short trading history has fewer options than an established limited company. So instead of naming one universal winner, this guide compares cards on the same criteria side by side.

Before comparing individual cards, it's worth understanding the type of card you're looking for and the trade-offs between them. Our guides on how to choose the right credit card for your business and the different types of business credit cards cover this in more depth. 

Each card below is assessed on the same criteria: annual fee, cashback or rewards, representative APR, interest-free period, credit limit, and eligibility. Rates and fees change, so treat the figures here as a snapshot correct as of September 2026, and always check the provider's own terms before applying.

Business credit card comparison table

Two cards worth a closer look

The table above covers all nine cards on the same criteria, but two are worth a closer look. Capital on Tap offers uncapped 1% cashback boosted to 1.25% on the Pro plan for preloaded funds and daily repayments; iwoca offers a flat 1% cashback rate from the first pound. Capital on Tap is the only one of the two that lets you redeem rewards as cash, gift cards, or convert to points, rather than cashback only.

Capital on Tap Business Credit Card

Best for flexible rewards

Overview: The Capital on Tap Business Credit Card is built for UK small businesses that want straightforward cashback, a high credit limit, and no foreign exchange fees, without needing an existing business current account with us first.

Key features:

• Cashback: Uncapped 1% cashback on all spending on the Free plan, rising to 1.25% on preloaded spend and daily repayments on Pro.

• Fees: £0 annual fee on Free, £299 a year on Pro. No FX fees and no ATM withdrawal fees on either plan.

• Employee cards: Unlimited free employee cards, with individual spending controls.

• Rewards redemption: Redeem points for cash, gift cards, or convert to Avios, Virgin Points, Go Coins, or Radisson Rewards.

Eligibility: UK limited companies and LLPs only. Sole traders are not eligible.

iwoca Credit Card

Cashback applied automatically, with no other redemption choice

Overview: The iwoca Credit Card is aimed at UK business owners who want a flat cashback rate and none of the account fees that come with some bank cards.

Key features:

• Cashback: 1% cashback on all spending, uncapped, matching Capital on Tap's Free-tier rate.

• Fees: No annual fee, no foreign exchange fees, no late payment fees.

• Employee cards: Additional cards available for employees, with individual spending limits and centralised billing.

• Rewards options: Cashback only, applied automatically to your balance each month. No option to take it as cash, gift cards, or convert it to points.

Eligibility: UK limited companies and LLPs only. Sole traders are not eligible.

What these numbers are actually worth

Headline cashback rates don't mean much until you put a real spend figure against them. Take a business spending £5,000 a month, £60,000 a year, a reasonable figure for an established small business running most of its day-to-day costs through one card.

At this spend level, the headline rate alone doesn't separate Capital on Tap's Free tier from iwoca, both pay out £600 with no conditions attached. What differs is what happens to it: Capital on Tap lets you take that £600 as cash, gift cards, or convert it to Avios, Virgin Points, Go Coins, or Radisson Rewards; iwoca pays it automatically to your balance with no other choice. 

Pro only overtakes Free on cashback once annual card spend passes roughly £120,000, the £299 fee otherwise outweighs the extra 0.25%. A business spending £15,000 a month, £180,000 a year, would net £1,951 on Pro against £1,800 on Free. Below that spend level, Free is the better deal on cashback alone, and Pro's value comes from its other perks: unlimited access to 1,800+ airport lounges worldwide, Radisson Rewards VIP status, improved Avios and Virgin Points conversion rates, and a complimentary Times and Sunday Times subscription.

None of this settles which card is right for a given business, that still comes down to spend pattern, trading history and how you want to use the rewards. But Capital on Tap is the only one of the three here where you actually choose how that reward is used, rather than having it paid out automatically with no other option.

Choosing between these cards

Here's how these nine cards differ on the factors that usually decide the choice for a small business.

• If flexible rewards matter most: Capital on Tap is the only card on this list that lets you redeem the same rewards balance as cash, gift cards, or convert to Avios, Virgin Points or Radisson Rewards, including for travel, rather than cashback or points only.

• If you're a newer business: Capital on Tap doesn’t require a minimum trading history or turnover requirement. 

• If a high credit limit matters and you don't want to open a new account: Capital on Tap offers up to £250,000, well above Lloyds' £25,000 cap and the unstated, assessment-based limits on the other bank cards.

• If you already bank with a high street provider: Your own bank's card (Lloyds, NatWest, Santander or Metro Bank) means skipping a fresh credit application, though usually at a higher representative APR than the fintech options.

• If you'd rather not open a new business account first: Capital on Tap and iwoca don't require one. Lloyds, NatWest, Santander and Metro Bank all require an existing business current account with them before you can apply.

• If your business isn't a limited company or LLP: Barclaycard Select Cashback is the only card on this list open to sole traders and partnerships without a bank account with the provider. Lloyds, NatWest and Santander also accept them, but only if you already hold a business current account with them.

If your credit history is limited or patchy

A short trading history or an imperfect credit file doesn't rule out every card here. Many providers use some version of a two-stage process, a soft search on your personal credit file and a hard search on your business credit file, though processes vary between providers, so it's worth checking before you apply.

Applying for the Capital on Tap Business Credit Card is specific about what that covers: at application, we run a soft search on the personal credit file of the applicant (the director or majority shareholder) only, which doesn't affect your personal credit score and isn't visible to other lenders. No search touches your business's credit file at this stage. A hard search only happens once you decide to sign the credit agreement, and even then it's on your business's credit file, not your personal one. That means you can find out if you're approved without any visible mark on your business's credit file, and no minimum trading history is required either, so a business without years of financial history behind it can still apply.

The bottom line

For most UK small businesses the Capital on Tap Business Credit Card is the strongest all-round choice on this list: uncapped 1% cashback from the first pound, up to £250,000 in credit, no foreign exchange fees, no minimum trading history, and rewards you can take as cash, gift cards, or convert to travel rewards.
