17 UK SME Credit Card Debt Statistics for 2026: Usage, Costs, Arrears and Lending Risks

UK SME credit card debt is hard to measure with precision. That is the first important point. No official dataset breaks out credit card balances for small and medium-sized enterprises only. Most public data combines business and consumer card balances, or tracks SME finance at a wider level.

Even so, the available evidence gives a clear picture. Credit cards remain one of the most common forms of external finance used by UK SMEs. They are flexible, fast, and easy to access. But they are also one of the most expensive ways to borrow if a balance is carried.

The SME Finance Monitor Q4 2024 reported that about 15% of UK SMEs used business credit cards in 2024, rising to 16% in Q4 2024. Usage had peaked at around 20% in Q3 2023 before falling to around 13% by Q3 2024 as borrowing costs rose. For more background on the broader card market, see our guide to business credit card usage statistics in the UK.

At the same time, wider UK card balances remain large. UK credit card debt, including mostly consumer balances and some business balances, reached about £73.2 billion in March 2025, according to UK credit card market data cited in the research. For comparison, the British Business Bank has placed total SME bank lending at around £188 billion in 2022.

This article reviews the latest UK SME credit card debt statistics for 2026. It also explains what the numbers mean for working capital, borrowing costs, arrears, insolvency risk, and the outlook for the rest of 2026.

Key UK SME Credit Card Debt Statistics for 2026

The most useful way to read the market is to separate confirmed SME data from wider card market proxies. SME credit card usage is measured by surveys such as the SME Finance Monitor. SME card balances, default rates, and APRs are not published as a clean official series.

How Many UK SMEs Use Credit Cards for Finance?

Credit cards are not used by most UK SMEs. But among external finance products, they are still highly important.

The SME Finance Monitor found that 15% of UK SMEs used business credit cards in 2024. In Q4 2024, the figure was 16%. That placed cards ahead of overdrafts and loans as a single finance type.

This matters because credit cards sit in a grey area between payments and borrowing. Some businesses use them only to manage spend. Others carry balances and use them as a working capital line. The risk sits with the second group.

SME Credit Card Usage Has Fallen Since 2023

The research shows that business credit card usage peaked at about 20% in Q3 2023. By Q3 2024, it had fallen to around 13%. This drop lines up with a period of high interest rates, tighter affordability checks, and lower appetite for new debt.

A fall in usage does not mean card debt risk has gone away. It may mean weaker demand for finance. It may also mean SMEs are avoiding high-cost credit where possible. But for firms with thin cash reserves, credit cards can still become the fallback option when supplier bills, tax payments, or wages arrive before customer cash.

Credit Cards Versus Overdrafts and Loans

In late 2024, 46% of SMEs used some form of external finance, according to the SME Finance Monitor. Within that group, 16% used credit cards, 11% used overdrafts, and 9% used loans.

Why SME Credit Card Debt Is Hard to Measure

The biggest data issue is simple. The UK does not publish an official SME-only credit card balance series.

That means no public source can say with certainty how many pounds of credit card debt are held by UK SMEs. We can track usage. We can compare wider card balances. We can review total SME lending. But the exact SME card debt stock is not split out.

Total UK Card Debt Is Not SME Card Debt

Total UK card balances reached about £73.2 billion in March 2025, according to UK credit card market data cited in the research. This figure includes mostly consumer balances and some business balances. It should not be treated as SME credit card debt.

Still, it gives useful context. It shows that revolving card debt remains a large part of the UK credit system. For SMEs, the risk is not the national card balance itself. The risk is that some firms are using high-cost revolving debt to cover cash flow gaps.

Total SME Lending Gives a Better Scale Reference

The British Business Bank reported total SME bank lending stock of about £188 billion in 2022. That wider figure includes loans, overdrafts, and other bank lending. Credit card debt is likely a small slice of total SME debt, but the exact share is not published.

The research also notes that Bank of England figures showed weak net corporate borrowing in 2025. SMEs borrowed net £0.7 billion in July 2025, up from £0.2 billion in June, with annual growth of about 0.9%. UK Finance reported gross SME bank lending of £4.6 billion in Q1 2025, up 14% year on year. These figures mostly reflect term loans and overdrafts, not card revolvers.

What SMEs Use Credit Cards For

SMEs use credit cards for two main reasons. First, they use them as a payment tool. Second, they use them as short-term working capital. The second use is where debt risk builds.

Surveys cited in the research found that about 53% of SMEs rely on cards for daily liquidity. This shows that many firms do not see credit cards as a back-office expense product only. They use them to keep cash moving.

Working Capital Is the Core Use Case

Working capital pressure can come from many places. Customers may pay late. Stock may need to be bought before sales arrive. VAT, PAYE, rent, and wages can fall due at fixed times. When cash timing is poor, a credit card can fill the gap.

That flexibility has value. But it also has a cost. A balance carried for a few weeks may be manageable. A balance carried for months can become a drag on margin. Businesses with repeat cash flow gaps should compare card use with working capital finance for small businesses or a structured working capital loan.

Retail and Scottish SMEs Appear More Exposed

The research cites survey findings that 60% of Scottish SMEs and retail-sector SMEs use cards as primary finance. This does not mean every firm in those groups carries debt. But it does suggest higher exposure to card-based funding.

Retail firms face a clear reason for this. Many must buy stock before they can sell it. They also face seasonal trading swings. For firms with low cash reserves, cards can become an informal stock finance tool.

Regional Differences in UK SME Credit Card Usage

Regional variation is modest, but it is useful. In H1 2024, reported SME credit card usage ranged from about 12% to 17% across UK nations and regions.

The gap between 12% and 17% may reflect local sector mix, business size, and access to bank finance. For example, regions with more micro firms, tourism, hospitality, retail, or seasonal trade may see higher use of flexible credit.

SME Credit Card APRs Are Much Higher Than Loan Rates

The cost gap is the clearest financial risk in the data.

The Bank of England’s January 2025 money and credit data showed an effective interest rate of about 21.9% on interest-bearing credit cards. The same research notes that new SME unsecured loan rates averaged about 7.0% in January 2025.

In plain terms, credit card debt cost roughly three times as much as a typical new unsecured SME loan proxy at that point. For a deeper guide to rate structure, see our article on how interest rates work on UK business loans.

Why Base Rate Matters for Business Card Debt

The Bank of England raised Bank Rate from 0.5% in March 2022 to 5.25% in August 2023. This increased funding costs for lenders and raised the price of credit across the market.

By December 2025, Bank Rate had eased to around 3.75%. That should help some borrowers during 2026. But credit card rates may not fall as fast as base rates. Card pricing also reflects risk, defaults, funding costs, and issuer margins. You can track current rate changes on our Bank of England base rate live page.

Business Cards May Have Fewer Consumer Protections

Business credit cards are treated as commercial lending. The research notes that they are not subject to the same FCA consumer credit caps that apply to consumer credit products. Some smaller business products may fall under the Consumer Credit Act if turnover is below £25 million, but in practice business card APRs remain less tightly capped than consumer credit.

Repayment Stress, Arrears and Defaults

Official UK data does not separate SME business-card delinquencies in a clean public series. That means repayment stress must be read through proxies.

Consumer card reports cited in the research noted that around 3% to 4% of card accounts were seriously delinquent, meaning 12 or more months overdue, in recent years. This is not an SME-specific figure. But it gives a broad signal of stress in revolving credit.

SME Arrears Are Hidden Inside Wider Data

No public source gives a recent charge-off rate for SME credit card debt. Banks publish impairment rates for wider SME lending, and the research notes that these were still below 1% of SME loan balances in 2025 reports. But this does not isolate cards.

This matters because card debt is unsecured and expensive. If a business is already under margin pressure, high APR debt can reduce cash flow faster than a lower-cost loan. Firms comparing fees should also review our guide on business loan APR, fees, and total repayable.

Late Payments and Input Costs Add Pressure

The Bank of England Agents’ summary for Q3 2025 noted that some SMEs were drawing additional working-capital credit due to late customer payments and higher input costs. That pattern supports the idea that some SMEs are carrying revolving balances to manage timing gaps.

When rates rose, credit conditions also tightened. The Bank of England Credit Conditions Survey reported subdued demand for SME finance by late 2024, with affordability issues among the smallest firms.

Company Insolvencies Remain Elevated

The Insolvency Service reported 1,744 company insolvencies in England and Wales in January 2026. That was 14% below January 2025, but still high by long-run standards.

The research also notes that annual company insolvencies were around 23,000 to 25,000 in each year from 2023 to 2025. This is equal to about one in 193 companies per year. High insolvency levels suggest that many firms still have weak cash buffers. For wider context, see our analysis of business insolvency survival rates in the UK.

How SME Credit Card Debt Compares With Other Finance

Credit cards have a clear role. They work best for short gaps, small purchases, staff expenses, supplier payments, and cash timing issues. They are not designed for long-term working capital.

For larger or longer needs, SMEs should compare cards with loans, overdrafts, invoice finance, asset finance, and revolving credit facilities. Firms that need flexible repeat access to funding can also compare cards with a revolving credit loan.

The Main Risk Is Not Card Use. It Is Revolving Debt.

A business that pays its card in full can benefit from control, records, rewards, and short-term float. A business that carries a growing balance pays for flexibility through high interest.

This is why average card balances and interest-bearing account shares matter. The research cites consumer data showing an average balance per active card of £1,845 in March 2025. It also notes that about 48.6% of all UK credit card accounts were interest-bearing in early 2025. These are consumer and wider market figures, not SME-only figures. But they show how common interest-bearing card debt can be.

The Lender Landscape for SME Credit Cards

The UK card market is concentrated around large issuers. UK Finance data cited in the research shows that Lloyds, Barclays, and HSBC held about 50% of all outstanding card debt combined in 2024. Lloyds alone held 21.9%.

These figures relate to all outstanding card debt, not SME-only card lending. Still, they show why large banking groups remain central to business card supply.

Challenger Banks and Fintechs Are Growing From a Small Base

Challenger banks and fintech firms have grown in SME banking. But the research notes that their share of SME card lending remained small as of 2025.

The bigger fintech shift is happening around Open Banking, digital underwriting, invoice discounting, and merchant cash advances. These tools can help lenders assess cash flow faster. They may improve access for under-served SMEs, but they do not remove the cost risk of short-term credit. Retail and hospitality firms that use card sales as a funding base should understand how merchant cash advances work before comparing them with credit cards.

Regulation and Data Gaps in Business Credit Cards

Business credit cards sit in a different regulatory space from consumer cards. That matters for pricing and protection.

The research notes that business cards are treated as commercial lending. They do not carry the same consumer credit protections in many cases. This gives issuers more pricing power, especially where a product falls outside consumer credit rules.

Basel 3.1 Could Affect SME Lending Costs

The research also flags Basel 3.1 as a 2026 risk. The expected removal of the SME supporting factor may raise capital costs for some SME lending. If bank loans become harder or more costly for smaller firms, some borrowers may lean more on flexible credit products, including cards.

This is not a certainty. It is a risk path. If traditional SME lending stays selective, credit cards may remain a bridge for firms that need quick access and cannot secure cheaper finance.

What the Statistics Mean for UK SMEs in 2026

The data does not show a broad surge in SME credit card borrowing. It shows something more specific. A minority of SMEs use cards, but those cards are a key finance tool. The firms most exposed are likely those using cards as a standing working capital line.

That distinction matters. A card used for controlled monthly spend is low risk. A card used to cover payroll, rent, VAT, or supplier arrears can signal deeper cash flow strain.

The Firms Most at Risk

The firms most at risk are likely to share five traits:

• Low cash reserves
• Late-paying customers
• Seasonal revenue
• Thin gross margins
• Weak access to cheaper loan or overdraft facilities

Retail, hospitality, micro businesses, and seasonal firms may face higher exposure. The research also points to higher card use among micro and retail SMEs, and among Scottish SMEs.

The Cost Gap Is the Strategic Issue

The 21.9% card APR proxy versus the 7.0% SME unsecured loan rate is the core financial warning. If a business carries £10,000 of card debt for a full year at roughly 21.9%, the interest cost can be large enough to damage profit. The same level of borrowing under a lower-cost loan may be easier to manage.

That does not make cards bad. It makes them specific. They are useful for short periods, but poor as a long-term funding base. SMEs that want to improve their lending options can also check their profile using the free business credit checker.

Outlook for the Rest of 2026

The base case for the rest of 2026 is cautious improvement, not a sharp recovery.

Lower Bank Rate should reduce pressure over time. The move from a 5.25% peak in August 2023 to around 3.75% by December 2025 should help credit conditions. But SMEs may not feel the full benefit at once. Card APRs tend to stay high because they price in credit risk, not just base rate movements.

Base Case: Card Usage Stays in the Low-to-Mid Teens

The most likely outcome is that SME credit card usage stays close to the 13% to 16% range seen during 2024. Demand for new credit remains low, with only about 3.5% of SMEs applying for new finance in 2024. Many firms remain cautious about borrowing.

Upside Case: Lower Rates Ease Repayment Stress

If inflation eases and customer demand improves, SMEs may rebuild cash buffers. That would reduce the need to roll card balances. It could also improve loan approvals for stronger firms, allowing them to replace expensive revolving debt with cheaper structured finance.

Downside Case: Tight Lending Pushes Firms Back to Cards

If Basel 3.1 raises bank capital costs, or if lenders stay cautious, smaller firms may struggle to access loans. In that case, cards may remain a fallback. This would be most likely among micro firms, retailers, and firms with uneven cash flow.

Final View

UK SME credit card debt is not a large, transparent market in the way that SME bank lending is. The data is fragmented, and several key figures are missing. But the direction of risk is clear.

Credit cards remain a common finance tool for SMEs. They are used more often than overdrafts and loans as a single product. They are also far more expensive when balances are carried.

For 2026, the main question is not whether SMEs will stop using credit cards. They will not. The real question is whether firms can limit cards to short-term cash timing, rather than relying on them as a long-term working capital base.

If rates keep easing and cash flow improves, card debt pressure should soften. If lending remains tight and late payments continue, more SMEs may carry expensive balances for longer. That would keep credit card debt near the centre of the UK small business finance risk story in 2026.
