Introduction

A business credit card can be a genuinely useful tool for a small business or sole trader: it separates business and personal spending, smooths out cash flow, earns cashback or rewards on money you were spending anyway, and — used properly — helps build a business credit history. But the UK market shifted significantly in early 2026, and some of the most popular cards changed who they’ll accept.

This guide compares the best business credit cards available to UK small businesses and sole traders in 2026, covering fees, APRs, cashback and rewards, and — crucially — eligibility, because that’s where a lot of applications now fall down. It’s written to help you make an informed choice, not to push a particular card. As with any borrowing, the right answer depends on your circumstances, so treat this as a starting point.

First: A Big 2026 Eligibility Change

Before comparing rewards and rates, check the card is actually open to you — because the landscape changed in January 2026:

• American Express dropped sole traders from its Business Gold and Business Platinum cards. Both are now limited companies and LLPs only.
• Capital on Tap (both its free and paid versions) requires a limited company or LLP — sole traders are not eligible. (This catches people out, as older guides often recommend it to sole traders.)
• Funding Circle’s business card is also limited-company only.

So if you’re a sole trader, your realistic options in 2026 include Barclaycard Select Cashback, the Tide Business Credit Card, the British Airways Amex Accelerating Business card, Santander Business Cashback, and the high-street bank cards (Lloyds, HSBC, NatWest) — though those generally require a business current account with that same bank.

Credit Card vs Charge Card — Know the Difference

An important distinction:

• A business credit card lets you carry a balance from month to month, paying interest on whatever you don’t clear.
• A charge card (such as American Express Business Gold or Platinum) must be paid in full every month. There’s no interest, but late or partial payment triggers fees and possible suspension.

Charge cards often carry richer rewards but demand discipline; credit cards give flexibility but at a high interest rate if you carry a balance.

What to Look For

• Annual fee — and whether the rewards you’d realistically earn exceed it
• Representative APR — important only if you’ll ever carry a balance (business card APRs are high)
• Cashback or rewards rate — and any spending thresholds or caps
• Foreign transaction fees — increasingly relevant with international SaaS subscriptions
• Eligibility — sole trader vs limited company, turnover, and trading history requirements
• Soft vs hard credit check — some cards let you check eligibility without affecting your credit score
• Business current account requirement — some cards require an account with the same provider

The Best Business Credit Cards for 2026

Capital on Tap (Free) — Best All-Rounder (Limited Companies & LLPs)

For most limited companies, Capital on Tap’s free Business Credit Card is the strongest no-fee all-rounder. It offers 1% uncapped cashback on all spending (or you can convert to Avios instead), no annual fee, no foreign transaction fees, and up to 56 days of interest-free credit. The representative APR starts from around 13.86% (variable) — among the lowest available — and it runs a soft credit check first, giving an instant decision without denting your credit score. Credit limits range from about £1,000 up to £250,000 for established businesses. There’s also a paid Pro version that adds lounge access and extra perks for an annual fee, but the free card delivers most of the value.

• Eligibility: Limited companies and LLPs only (not sole traders)
• Best for: Limited companies wanting no-fee cashback and a low APR

American Express Business Gold — Best for Rewards (Limited Companies & LLPs)

If your business spends heavily and you pay the balance in full each month, Amex Business Gold typically delivers the highest rewards value, via Membership Rewards points (which transfer 1:1 to Avios and other partners), with enhanced earning on some travel spend. It’s a charge card, so it must be cleared monthly, and it carries an annual fee — so it pays off for higher spenders who value travel rewards. Note that Amex isn’t accepted everywhere in the UK, which is worth factoring in.

• Eligibility: Limited companies and LLPs only (sole traders dropped in January 2026)
• Best for: High-spending companies that clear the balance monthly and want travel rewards

Barclaycard Select Cashback — Best for Sole Traders

Barclaycard is the standout for the unincorporated: its business cards accept sole traders, partnerships, limited companies and LLPs, and — unusually — you don’t need a Barclays business current account. The Select Cashback card has no annual fee and pays 1% uncapped cashback, but only on monthly spend above £2,000 — below that, you earn nothing, so it’s not suited to very light spenders. Its representative APR (around 25.5%, variable) is high, so it’s best used as a card you settle in full each month. Barclaycard also offers a Premium Plus card (with a £150 fee, a short 0% introductory purchase period, and lower FX fees) and a Select Charge card.

• Eligibility: Sole traders, partnerships, limited companies, LLPs; no Barclays account needed
• Best for: Sole traders and small businesses spending £2,000+ a month who clear the balance

Tide Business Credit Card — Sole-Trader-Friendly

Tide’s business credit card is one of the more accessible options for sole traders, and — like Capital on Tap — runs a soft credit check first, so you can test eligibility without affecting your score. It’s a natural fit if you already use Tide for business banking.

• Eligibility: Accepts sole traders
• Best for: Sole traders (especially existing Tide users) who want a soft-check application

British Airways Amex Accelerating Business — Best for Avios (Accepts Sole Traders)

If you want to earn Avios and you’re a sole trader shut out of Business Gold, the BA Amex Accelerating Business card still accepts sole traders and earns around 1.5 Avios per £1. As an Amex charge product it needs clearing monthly, and Amex acceptance applies — but for frequent travellers it’s a strong earner.

• Eligibility: Accepts sole traders
• Best for: Avios collectors and frequent business travellers

Santander Business Cashback — A Solid Bank Option (Accepts Sole Traders)

Santander’s Business Cashback card accepts sole traders and pays cashback on spending, for a modest annual fee (around £30). As with most high-street options, check whether a business current account is required and whether the cashback outweighs the fee for your spend level.

• Eligibility: Accepts sole traders
• Best for: Businesses wanting a straightforward bank-backed cashback card

Sole Trader or Limited Company? It Matters More Than It Used To

The 2026 changes mean your business structure now heavily shapes your options:

• Limited companies and LLPs have the widest choice, including Capital on Tap and Amex Business Gold.
• Sole traders should focus on Barclaycard, Tide, the BA Amex Accelerating card, Santander, or a high-street bank card. Bear in mind that sole traders typically act as personal guarantors, so your personal credit score matters, and most providers want to see 6–12 months of trading history.

If you have a lower credit score, cards that run a soft check first (Capital on Tap for limited companies, Tide for sole traders) let you test eligibility safely before a hard search appears on your file.

Important Things to Know Before You Apply

• The APR only matters if you carry a balance — but if you do, it hurts. Business card representative APRs are high (often 25–35%+), which can more than wipe out any cashback. These cards work best as transactional cards you clear in full each month.
• Personal guarantees are common. Especially for sole traders and small companies, you may be personally liable for the debt.
• Credit checks vary. Soft checks (Capital on Tap, Tide) don’t affect your score; hard checks (Amex, Barclaycard, banks) cause a small temporary dip.
• Cashback and tax. HMRC generally treats cashback as a discount rather than taxable income, but personal redemptions of business rewards can be a benefit in kind — check with your accountant for your situation.
• Business account requirements. High-street bank cards usually require a business current account with that bank; Barclaycard, the fintechs, and Amex generally don’t.

FAQ

Can sole traders get a business credit card in the UK?

Yes, but the options narrowed in 2026. American Express dropped sole traders from Business Gold and Platinum in January 2026, and Capital on Tap only accepts limited companies and LLPs. Sole traders can still apply for Barclaycard Select Cashback, the Tide Business Credit Card, the British Airways Amex Accelerating card, Santander Business Cashback, and various high-street bank cards. Capital on Tap and Tide (for limited companies and sole traders respectively) run a soft credit check first.

What’s the best no-fee business credit card?

For limited companies, Capital on Tap’s free card is a strong choice — 1% uncapped cashback, no foreign transaction fees, and a low representative APR. For sole traders, Barclaycard Select Cashback has no annual fee and pays 1% cashback, though only on monthly spend above £2,000. Always check the rewards you’d realistically earn against any fee.

Do I need a business bank account to get a business credit card?

It depends on the provider. High-street bank cards (Lloyds, HSBC, NatWest, Santander) generally require a business current account with that same bank. Barclaycard, the fintech providers (like Capital on Tap and Tide), and American Express typically don’t, so you can hold your account with Starling, Monzo, Mettle, or another provider and still get their card.

Is a business credit card worth it if I pay interest?

Generally not for long. Business credit card APRs are high (often 25–35%+ representative), which quickly outweighs any cashback or rewards. These cards deliver value when used as transactional cards that you clear in full each month. If you need to borrow over a longer period, a dedicated business loan or overdraft is usually far cheaper than carrying a card balance.

Conclusion

The best business credit card for you in 2026 depends first on your business structure, and then on how you spend. For limited companies, Capital on Tap’s free card is an excellent no-fee all-rounder, while heavy spenders who clear monthly may earn more with Amex Business Gold. For sole traders, Barclaycard Select Cashback and Tide are the most accessible starting points, with the BA Amex Accelerating card a strong option for Avios collectors.

Whichever you choose, the golden rule is the same: use it as a transactional card, clear the balance in full each month to avoid the high interest, and make sure the rewards genuinely exceed any annual fee. Used that way, a business credit card is a useful, low-cost tool; used to carry debt, it’s an expensive one.
