What Is a Line of Credit? The Complete UK Business Guide for 2026

What Is a Line of Credit and How Does It Work?

A line of credit (LOC) is a pre-approved borrowing limit set by a lender. You draw from it when you need funds, repay what you've used, and borrow again — all without going through a fresh application each time. You only pay interest on the outstanding balance, not the full limit.

Think of it like a business overdraft, but often with higher limits and more structured repayment terms. A restaurant owner covering a slow January, an e-commerce store buying seasonal stock, or a dental practice bridging a gap between invoices and supplier payments — a line of credit fits these real-world needs well.

How Does a Line of Credit Work Differently from a Loan?

A line of credit is revolving and flexible; a business loan is a one-time lump sum with fixed repayments. With a loan, you receive the full amount upfront and repay it on a set schedule regardless of whether you used every penny. With a line of credit, you only borrow what you need, when you need it.

For a deeper look at how UK business loans are structured, the Business Loans guides on Funding Fred cover the main product types side by side.

Secured vs Unsecured Lines of Credit: What's the Difference?

A secured line of credit requires you to put up an asset as collateral (such as property or equipment). An unsecured line of credit requires no collateral — the lender relies on your creditworthiness and business performance instead.

For most UK small business owners, an unsecured line of credit is the more practical option. You're not putting your home or equipment on the line. Flexible Criteria lenders using Open Banking can assess your real cash flow rather than relying purely on a credit score, which opens access for businesses that wouldn't qualify at a traditional bank.

If you're interested in how asset-backed finance compares, the Asset Finance guides on Funding Fred break down the secured borrowing landscape in detail.

What Credit Score Do You Need to Qualify for a Line of Credit?

For a personal line of credit, most mainstream lenders look for a credit score of around 700 or higher, along with a solid history of on-time debt repayments. For a business line of credit, the threshold varies significantly by lender.

Beyond the score itself, lenders also assess:

• Monthly or annual turnover
• Time in business (many require at least 6 months)
• Existing debt obligations
• Industry type and perceived risk

The key point for UK SME owners: Your credit score is one input, not the whole picture. A business turning over £30,000 a month with a patchy credit history may still qualify with the right lender. That's where Smart Tech and Open Banking assessments change the game compared to traditional bank processes.

Can You Get a Line of Credit with Bad Credit?

Yes, it's possible to get a line of credit with bad credit, but your options narrow and costs typically rise. Lenders that use Open Banking and real-time cash flow data are far more likely to approve businesses with imperfect credit than traditional banks.

For a full breakdown of lenders that don't rely on hard credit checks to get started, see the Best Business Loans No Credit Check guide.

No hard check to start — many flexible lenders run a soft eligibility check first, so exploring your options won't damage your credit score.

How Much Can You Borrow with a Business Line of Credit?

The amount you can borrow depends on your business revenue, credit profile, and the lender's maximum limits. For UK SMEs, business lines of credit typically range from £5,000 to £250,000, though many alternative lenders focus on the £10,000 to £150,000 range.

For Funding Fred's target audience — UK businesses looking for capital between £40,000 and £120,000 — a business line of credit can sit comfortably within that range, provided turnover and trading history support it.

What Are the Interest Rates for Lines of Credit?

Interest rates on lines of credit are often variable, meaning they can change over time based on market conditions and lender terms. For UK business lines of credit in 2026, rates vary widely depending on whether the product is secured or unsecured, and the lender type.

Typical rate ranges (estimates based on market norms):

For a current snapshot of what UK businesses are paying across different loan products, the Average Business Loan Interest Rates: June 2026 Update gives a detailed breakdown.

Additional fees to watch for:

• Arrangement or setup fees (often 1% to 3% of the credit limit)
• Annual maintenance fees
• Draw fees (charged each time you access funds)
• Early repayment charges on some products

The practical impact: On a £50,000 line of credit at 20% per annum, drawing £20,000 for three months costs roughly £1,000 in interest. Compare that to a fixed loan where you'd pay interest on the full £50,000 from day one.

Pros and Cons of Getting a Line of Credit

A line of credit suits businesses with variable cash flow needs, but it's not the right tool for every situation. Here's an honest assessment.

Is a Line of Credit Good for Small Business Owners?

Yes — for the right type of business, a line of credit is one of the most practical funding tools available. It's particularly well-suited to businesses with seasonal revenue, irregular payment cycles, or unpredictable stock needs.

Traditional Banks vs Funding Fred:

When Should You Use a Line of Credit Instead of a Credit Card?

Use a line of credit when you need higher borrowing limits, lower interest rates, or more structured repayment terms than a business credit card offers. A credit card is fine for small, frequent purchases. A line of credit is better for larger, planned draws where cost matters.

The cost difference matters: Carrying £20,000 on a business credit card at 25% APR costs significantly more than drawing the same amount from a line of credit at 15% to 18%, especially over several months.

How Quickly Can You Access Money from a Line of Credit?

Once a line of credit is approved and set up, funds can typically be accessed within one to two business days of making a draw request. The initial approval process is where timing varies most.

For businesses that need capital quickly — covering an unexpected supplier invoice or a sudden stock opportunity — the speed of initial approval matters as much as the rate. Alternative lenders using Open Banking can assess your application faster because they're reading live bank data rather than waiting for paper statements.

What Happens If You Miss Payments on Your Line of Credit?

Missing payments on a line of credit triggers a chain of consequences that escalate quickly. At minimum, you'll face late payment fees. More seriously, your credit profile takes a hit and your lender may reduce or freeze your available limit.

What typically happens:

1. 1

   Late fee charged

   usually within days of a missed payment

2. 2

   Interest continues to accrue

   on the outstanding balance, including any fees added

3. 3

   Credit score impact

   missed payments are reported to credit agencies, damaging your score

4. 4

   Limit reduction or freeze

   the lender may reduce your available credit or suspend draw access

5. 5

   Default notice

   if payments are missed repeatedly, the lender may issue a formal default

6. 6

   Debt collection

   persistent non-payment can lead to the debt being passed to a collection agency or, for secured LOCs, asset recovery

Common Mistakes People Make with Lines of Credit

The most common mistake is treating a line of credit as extra income rather than a short-term cash flow tool. Here are the errors that cost business owners the most.

1. 1

   Maxing out the limit and staying there

   A line of credit works best when you draw, repay, and keep the limit available. Sitting at maximum utilisation increases your credit utilisation ratio, which harms your credit score and signals financial stress to lenders.

2. 2

   Using it to fund ongoing losses

   A LOC should bridge a temporary gap, not prop up a business that's consistently spending more than it earns. If you're drawing repeatedly and never fully repaying, that's a warning sign.

3. 3

   Ignoring variable rate risk

   Rates can rise. A line of credit that costs 15% today could cost 20% in 18 months. Build that possibility into your cost calculations before drawing large amounts.

4. 4

   Not reading the fee structure

   Setup fees, annual fees, and draw fees can significantly increase the true cost of borrowing. Always calculate the total cost of credit, not just the headline interest rate.

5. 5

   Missing the difference between draw period and repayment period

   Some LOCs require interest-only payments during the draw period, then switch to full principal-plus-interest repayments. That jump in monthly cost catches some business owners off guard.

6. 6

   Applying to multiple lenders simultaneously

   Each hard credit check leaves a mark on your file. Use a platform that offers a soft eligibility check first — No hard check to start — so you can explore options without damaging your score.

Conclusion

Understanding what is a line of credit is the first step to using one well. For UK small business owners, it's one of the most flexible funding tools available — but only when it's matched to the right need. Use it to bridge cash flow gaps, fund seasonal stock, or cover short-term costs. Don't use it to paper over structural losses.

The key decisions are straightforward:

Secured or unsecured?

Unsecured protects your assets and moves faster.

Bank or alternative lender?

Alternative lenders with Flexible Criteria and Open Banking assessments serve All Credit Types — not just those with perfect scores.

Line of credit or fixed loan?

If you need a one-off lump sum, a fixed Unsecured Loan is cleaner. If you need ongoing, flexible access, a line of credit wins.

1. Check your current monthly revenue and identify your realistic borrowing need
