Business Line of Credit UK: Rates, Requirements & How to Apply | Juice
Finding the right business line of credit in the UK means navigating different products, lenders, and terminology. This guide covers rates, eligibility, and the application process for UK businesses. It is part of our Business Line of Credit guide.
What is a business line of credit in the UK?
A business line of credit is a flexible funding facility that lets a business draw down funds up to an agreed limit — and repay them — on a revolving basis. In the UK, this type of product is most commonly structured as a revolving credit facility.
The terms are often used interchangeably. Whether a lender calls it a business line of credit, a revolving credit facility, or a working capital facility, the core mechanics are the same: you have access to a pre-approved limit, you draw down what you need, and interest applies only to the amount drawn.
This makes it fundamentally different from a term loan. A term loan delivers a fixed sum upfront, and interest accrues on the full balance from day one. A revolving credit facility gives you ongoing access to capital — useful for managing timing gaps between income and expenditure, covering seasonal variation, or bridging short-term cash flow requirements.
For finance directors and CFOs, the revolving structure offers something a term loan cannot: flexibility without waste. You are not paying for capital you are not using.
Business line of credit rates UK: what are typical costs?
Rates on a business line of credit in the UK vary considerably depending on the lender, the business profile, and the structure of the facility.
As a general guide, monthly interest rates on unsecured revolving credit facilities for UK SMEs typically range from around 0.9% to 3.5% per month on drawn balances. Secured facilities, or those with stronger credit profiles, may attract lower rates. Higher-risk or early-stage businesses may see rates above this range.
Several factors influence pricing:
— Trading history — lenders favour established businesses with a clear revenue track record.
— Turnover and cash flow quality — consistent, predictable revenue supports lower pricing.
— Security offered — personal guarantees or debentures can reduce the cost of the facility.
— Facility size — larger facilities may attract different pricing structures.
— Lender type — specialist lenders and high street banks price risk differently.
One of the key advantages of a revolving facility is that interest is charged only on the amount drawn — not the full approved limit. If your facility is £200,000 and you have drawn down £50,000, you pay interest on £50,000 only.
Always review the full cost of the facility, including any arrangement fees, annual review fees, and early repayment terms. Some lenders charge penalties for repaying early; others — including Juice — do not.
Eligibility: who can get a business line of credit in the UK?
Eligibility criteria vary by lender, but most specialist lenders and banks assess a consistent set of factors when reviewing a business line of credit application.
Business structure. Most lenders require the applicant to be a UK-registered limited company. Sole traders and partnerships may have access to some facilities, but the full range of revolving credit products is typically available to limited companies only.
Trading history. A minimum trading history of 12 to 24 months is standard. Some lenders require longer. A proven track record demonstrates that the business can generate consistent revenue and manage its obligations.
Annual turnover. Lenders set minimum turnover thresholds. For larger facilities, turnover requirements increase accordingly. A business seeking a £500,000 facility will typically need to demonstrate a turnover that supports that level of exposure.
Cash flow quality. Lenders look beyond headline revenue. They assess the consistency, predictability, and timing of cash inflows and outflows. Businesses with strong, repeating revenue cycles are viewed more favourably than those with irregular or highly seasonal income — though seasonal businesses can still access revolving facilities designed around their cash flow cycle.
Credit history. Both the business credit profile and, in many cases, the personal credit history of directors will be assessed. Adverse credit history does not automatically disqualify an application, but it will influence terms.
Directors and ownership. Lenders typically require details of all directors and significant shareholders. Personal guarantees are common — particularly for unsecured facilities.
Secured vs unsecured business line of credit in the UK
A business line of credit can be structured as secured or unsecured. Understanding the difference matters for both cost and risk management.
Unsecured facilities do not require the business to pledge specific assets as collateral. However, lenders typically require a personal guarantee from one or more directors. A personal guarantee means the guarantor accepts personal liability if the business defaults on the facility. This is a significant commitment and should be reviewed carefully before signing.
Secured facilities are backed by business assets — property, equipment, or a floating charge over the business's assets via a debenture. A debenture gives the lender a legal claim over the business's assets in the event of default. In exchange for this security, lenders typically offer lower rates or higher facility limits.
For most UK SMEs accessing revolving credit facilities up to £1,000,000, unsecured structures with a personal guarantee are the most common route. Larger or more complex facilities — particularly those arranged through banks — may require a debenture or property security.
When evaluating options, finance directors should weigh the cost saving from a secured structure against the operational and legal implications of granting a charge over business assets.
How to apply: the process step by step
The application process for a business line of credit varies between lenders, but the stages follow a broadly consistent pattern.
Step 1: Connect your accounts. Most specialist lenders now use open banking to review your business bank account data. This replaces lengthy document requests and allows the lender to assess cash flow, revenue consistency, and financial behaviour directly from live account data. The process is secure and typically takes minutes.
Step 2: Credit assessment. The lender reviews your business and personal credit profiles, trading history, turnover, and cash flow patterns. Some lenders use automated decisioning for smaller facilities; others combine data analysis with human underwriting review.
Step 3: Receive an offer. If the assessment is successful, you receive a facility offer — detailing the approved limit, the applicable rate, repayment terms, and any conditions. Review this carefully before accepting.
Step 4: Draw down funds. Once the facility is active, you can draw down funds as needed — up to your approved limit. Repayments replenish the available balance, keeping the facility revolving.
At Juice, the process is designed to be straightforward. You connect your business accounts, we carry out our credit assessment, and if approved, your Juice Flex facility is ready to use. Subject to status and lending criteria.
Provider comparison
How long does it take to get a business line of credit?
The timeline depends significantly on the type of lender you approach.
High street banks typically take weeks or months to process a business credit line application. The process often involves a relationship manager, significant documentation requirements, and multiple rounds of review. For businesses that need capital quickly, this can present a real operational constraint.
Specialist lenders operate on a faster timeline — typically days rather than weeks. The use of open banking data, automated credit assessment, and streamlined underwriting processes allows for quicker decisioning without compromising the rigour of the assessment.
For businesses managing live working capital requirements — a supplier payment due, a payroll cycle approaching, or a time-sensitive growth opportunity — the speed of specialist lenders is a material advantage.
Juice Flex is designed to be available when you need it. Once set up, drawing down funds is fast — giving your finance team the confidence that capital is accessible without lengthy reapplication processes.
Business line of credit providers in the UK
UK businesses have access to a range of providers when seeking a business line of credit. The landscape broadly divides into two categories.
High street banks offer revolving credit facilities and business overdrafts as part of their commercial banking suite. The advantages are familiarity, established relationships, and — for larger, well-established businesses — potentially competitive pricing. The disadvantages are process complexity, slow timelines, and a tendency to favour larger businesses or those with significant assets.
Specialist lenders have grown significantly in the UK SME market over the past decade. They offer focused products — often revolving credit facilities and working capital lines — with faster, more accessible application processes. Many use technology to streamline assessment and onboarding. Specialist lenders tend to be more responsive to cash-flow-based lending, rather than asset-based security.
When comparing providers, finance directors should evaluate total cost of the facility (not just headline rate), flexibility of drawdown and repayment, speed of access, and the lender's track record with businesses of a similar size and sector.

Managing your business line of credit: practical guidance
A revolving credit facility is most effective when it is actively managed as part of a broader working capital strategy. For CFOs and finance directors, the following principles apply.
Drawdown discipline. Draw down only what you need, when you need it. The revolving structure rewards precision — using the facility for specific, short-term timing gaps rather than as a general-purpose cash reserve. This minimises interest costs and keeps the facility available for genuine working capital needs.
Repayment timing. Repay drawn balances as soon as cash flow allows. Because the facility is revolving, early repayment frees up capacity immediately — and where there are no early repayment penalties, there is no cost to repaying ahead of schedule. Align repayments with your cash inflow cycle for maximum efficiency.
Integrate with cash flow forecasting. A revolving credit facility should sit within your 13-week or monthly cash flow forecast. Model when you expect to draw down, when you expect to repay, and what your available headroom will be at each point. This allows proactive facility management rather than reactive drawdown decisions.
Facility reviews. Most lenders conduct periodic reviews of the facility — typically annually. Prepare for these by having up-to-date management accounts, bank statements, and a clear narrative of your trading position. Demonstrating strong cash flow management during the review period is the most effective way to maintain or improve your facility terms.
Avoid facility creep. A revolving credit facility is a working capital tool — not a substitute for longer-term investment finance. If drawn balances are consistently high and rarely repaid, this may indicate the facility is being used for purposes it is not designed for. Review the underlying use regularly.
Monitor your headroom. Available headroom — the difference between your drawn balance and your approved limit — is your operational buffer. Maintain visibility of this figure as part of your daily or weekly cash management process.
