What Is a Business Line of Credit? UK Guide | Juice
Many UK business owners searching for a business line of credit find US content that doesn't translate to the UK market. This guide explains what a business line of credit is, how it works in the UK, and how to get one. It is part of our Business Line of Credit guide.
What is a business line of credit?
A business line of credit is a flexible funding facility that gives you access to a pre-approved pot of money. You draw down what you need, when you need it. You repay it, and the funds become available again.
Unlike a fixed-term business loan, you are not handed a lump sum on day one. You only use what you need — and you only pay interest on what you actually draw down. This makes it one of the most practical tools for managing working capital and cash flow.
For UK SMEs, a business line of credit is typically used to smooth out timing gaps — those periods between spending money and getting paid. It keeps operations moving without the cost of carrying a large balance you don't need.
Business line of credit vs revolving credit facility: what’s the difference?
In short: nothing. They are the same product with different names used on different sides of the Atlantic.
“Business line of credit” is the term most commonly used in the United States. In the UK, the same facility is more often called a revolving credit facility. Both describe a flexible, reusable credit arrangement where you draw down funds, repay them, and draw again within an agreed limit.
UK lenders — including banks, challenger lenders, and fintech providers — tend to use “revolving credit facility” in their product terms. But if you have been searching for a “business line of credit UK”, you are looking for exactly the same thing.
Throughout this guide, we use both terms interchangeably. When you see “business line of credit”, think “revolving credit facility” — and vice versa.
How does a business line of credit work?
The mechanics are straightforward. A lender approves you for a credit limit — say, £100,000. That limit sits available to you. You draw down what you need, repay it, and the facility revolves back to its full limit.
Here is how the cycle works in practice:
1. Approval: You are approved for a credit limit based on your trading history and financial profile.
2. Draw down: You request a draw — the funds arrive in your account, often within 24 hours.
3. Use: You use the funds for a business purpose — stock, VAT, payroll, or a growth opportunity.
4. Repay: You repay what you drew, plus interest on the amount used.
5. Revolve: Your available balance returns to its original limit. The cycle begins again.
Worked example
Suppose your business has a £150,000 revolving credit facility. Here is how you might use it over a few months.
MonthActionAmountAvailable balanceMonth 1Draw down for stock purchase£40,000£110,000Month 2Repay draw + interest£40,000 + interest£150,000Month 3Draw down for VAT bill£25,000£125,000Month 3Draw down for marketing campaign£15,000£110,000Month 4Repay both draws + interest£40,000 + interest£150,000
You only ever pay interest on the amounts you draw down. When the facility is unused, it costs you nothing. That is the core appeal of a business line of credit — flexible access with costs matched precisely to usage.
There are no early repayment penalties with Juice Flex, so you can repay ahead of schedule and reduce your interest costs further.
What can you use a business line of credit for?
A business line of credit is an unrestricted working capital facility. Most UK SMEs use it for one or more of the following purposes.
Working capital and cash flow
The most common use. Businesses often collect revenue in arrears — after 30, 60, or even 90 days. A revolving credit facility bridges the timing gap between spending and getting paid. It keeps your business moving without stalling operations while waiting for invoices to clear.
Stock and inventory
Retailers, wholesalers, and product businesses regularly need to buy stock ahead of demand. A business credit line lets you move quickly — securing bulk orders or seasonal inventory — without tying up your reserves.
VAT and tax bills
Quarterly VAT payments can create significant pressure on cash flow. Drawing down from your revolving credit facility to cover a VAT bill — then repaying once customer payments arrive — is a common and practical strategy for UK businesses.
Payroll and operational costs
Revenue can be lumpy. Payroll is not. A business line of credit ensures you can meet payroll and cover operational costs in lean months without disrupting the business or the team.
Growth opportunities
Sometimes a new contract, a bulk discount, or a time-sensitive opportunity appears. A revolving credit facility means you can act immediately — without waiting weeks for a loan application to process. Speed is often the competitive advantage.
Business line of credit rates: what to expect in the UK
Rates vary by lender, facility size, and your business's risk profile. There is no single “standard” rate for a business line of credit in the UK.
What you can expect:
— Interest is charged only on the amount drawn down — not on the full credit limit.
— Rates are typically expressed as a monthly or annual percentage of the outstanding balance.
— Fintech and challenger lenders often use risk-based pricing — meaning your rate reflects your specific trading history and financial profile.
— Stronger financials and longer trading history generally result in more favourable rates.
Be cautious of any lender quoting a guaranteed rate before assessing your business. Responsible lenders price based on risk — which protects both the lender and the borrower.
When comparing offers, focus on the total cost of draw downs over your typical usage pattern — not just the headline rate. A slightly higher rate on a facility you use sparingly can cost less overall than a lower rate with high arrangement fees.
Who qualifies for a business line of credit in the UK?
Eligibility criteria vary between lenders. At Juice, the core requirements for Juice Flex are straightforward.
Basic eligibility criteria
— UK limited company: Juice Flex is available to UK-registered limited companies.
— Trading history: A minimum of 6 months of trading history is required.
— Monthly turnover: Your business should be generating £20,000 or more in monthly revenue.
Meeting the minimum criteria does not guarantee approval. All applications are subject to status and lending criteria — your individual financial profile, trading history, and credit assessment will determine the outcome.
What lenders look at
Lenders typically assess a combination of factors when reviewing an application for a business line of credit:
— Revenue consistency and trends — is the business growing or contracting?
— Cash flow patterns — are there regular timing gaps that a revolving facility would address?
— Outstanding liabilities — what existing credit facilities does the business carry?
— Director credit profile — some lenders review the personal credit history of directors.
Connecting your business bank account and accounting software to an application portal — as Juice allows — speeds up this assessment considerably. It removes manual paperwork and gives the lender a real-time view of your financial position.
Secured vs unsecured business line of credit
Business lines of credit can be secured or unsecured. Understanding the difference matters before you apply.
Secured business line of credit
A secured facility is backed by an asset — typically property, equipment, or a debenture over the business. Because the lender holds security, they carry less risk. This can result in higher credit limits or lower rates. However, your assets are at risk if you default.
Unsecured business line of credit
An unsecured facility requires no specific asset as collateral. The lender assesses risk purely on your business’s financial profile and trading history. This is a faster, simpler route for many SMEs — particularly those without significant assets to offer as security.
Juice Flex is an unsecured revolving credit facility. No property charge or fixed asset is required. For more detail, see our guide to unsecured revolving credit facilities.
The trade-off is that unsecured facilities may carry slightly higher rates than secured equivalents, and credit limits may be more conservative at the outset. As your trading relationship with the lender develops, limits can often be reviewed upward.
How to apply for a business line of credit
The application process for a business line of credit in the UK has become significantly faster in recent years — particularly with fintech lenders who use open banking and automated underwriting.
Here is what the typical process looks like with Juice:
Step 1: Connect your accounts
You connect your business bank account and accounting software securely via open banking. This gives Juice a real-time view of your trading history and cash flow — replacing weeks of manual document requests.
Step 2: Fast credit decision
Juice’s underwriting team reviews your application against your financial data. Decisions are typically fast — often within 24 hours for straightforward applications. You will receive a credit limit offer and the proposed terms of your revolving credit facility.
Step 3: Accept and draw down
Once you accept the facility terms, your credit line is live. You can draw down funds immediately — directly to your business bank account. From that point, the facility revolves. Draw down, repay, draw again — as your business needs dictate.
Step 4: Ongoing management
Juice Flex is managed through an online dashboard. You can see your available balance, outstanding draws, and repayment schedule at any time. There are no penalties for early repayment, so you can reduce your balance — and your interest costs — whenever it suits your cash flow.
