Business Line of Credit for CFOs: UK Guide for Finance Directors | Juice

Finance

A business line of credit is a working capital tool that most finance directors will evaluate at some point — but the structure, terms, and risks vary significantly between providers. This guide covers what CFOs and finance directors need to know: committed vs uncommitted facilities, drawdown mechanics, total cost of funds, and how to integrate a credit line into cash flow planning. It is part of our Business Line of Credit guide.

1. What CFOs need to know about business lines of credit

A business line of credit — or revolving credit facility — gives a business access to a pre-approved pool of capital. You draw what you need, repay it, and draw again. It is not a term loan. There is no fixed drawdown schedule and no requirement to use the full facility.

For a finance director managing working capital, that flexibility is the point. Seasonal peaks, delayed customer payments, and opportunistic supplier terms all create short-term cash flow gaps. A revolving credit facility lets you bridge those gaps on your own schedule, rather than negotiating an emergency facility under pressure.

In the UK, SMEs have historically relied on bank overdrafts or term loans for working capital. Both have significant structural limitations from a treasury perspective — limitations that a properly structured revolving credit facility avoids.

Juice Flex is a revolving credit facility for UK SMEs, available from £50,000 to £1,000,000. Subject to status and lending criteria.

2. Committed vs uncommitted credit lines: why the distinction matters

This is the most important structural question a CFO should ask when evaluating any credit facility: is it committed or uncommitted?

A committed facility is a contractual obligation on the lender’s part. For the term of the agreement, the lender cannot unilaterally withdraw the facility — provided you comply with the terms. You have certainty of access to capital. That certainty has real value in treasury risk management.

An uncommitted facility — the bank overdraft being the most common example — can be withdrawn at the lender’s discretion, often with minimal notice. There is no contractual entitlement to continued access. From a risk management perspective, you are relying on the lender’s goodwill rather than a contractual right.

The distinction matters most when you need the facility most. In periods of market stress or deteriorating credit conditions, uncommitted facilities are withdrawn. A committed revolving credit facility remains in place for its agreed term — giving you the working capital stability to plan and operate with confidence.

When evaluating any provider, ask directly: is this facility committed for the term, or can you withdraw it on demand? The answer should inform how you classify the facility in your treasury risk register.

3. How drawdown and repayment mechanics work

Understanding the operational mechanics of a revolving credit facility is essential before integrating it into your cash flow model.

Drawdown process. With a well-structured facility, drawdown should be straightforward. You submit a drawdown request — typically via an online portal — specifying the amount and purpose. The lender reviews the request against your available limit and facility terms. Funds are transferred to your nominated account, often within one business day.

Available limit. Your available limit at any time equals your total facility minus the current drawn balance. As you repay, the limit replenishes. This is the revolving mechanic — the facility does not reduce with each repayment, unlike a term loan.

Repayment flexibility. You can repay as much or as little as your cash flow permits — subject to any minimum repayment terms in the facility agreement. There are no fixed monthly instalments. This allows you to repay aggressively in high-cash periods and draw conservatively in tighter months.

No early repayment penalties. Juice Flex carries no early repayment penalties — meaning you can repay and redraw without cost. From a treasury perspective, this allows you to optimise the drawn balance dynamically rather than carrying unnecessary debt to avoid break costs.

Interest accrual. Interest accrues daily on the drawn balance only. If you draw nothing, you pay nothing — beyond any facility fee that may apply. This is materially different from a term loan, where interest accrues on the full balance from day one regardless of your actual utilisation.

4. Interest calculations: total cost of funds vs headline rate

The headline interest rate is rarely the full picture. A CFO evaluating a credit facility should model total cost of funds for their expected utilisation pattern — not compare APRs in isolation.

The components of total cost for a revolving credit facility typically include:

Interest on drawn balance — the primary cost, accruing daily on the outstanding amount

Arrangement fee — a one-off fee on facility establishment, sometimes expressed as a percentage of the facility limit

Facility fee — an ongoing fee on the total facility limit (whether drawn or not), charged to maintain the committed line

Draw fee — a per-drawdown fee charged on each individual drawdown request (not all providers charge this)

To compare facilities meaningfully, model the total cost for your specific anticipated usage pattern.

Worked example, total cost of funds (illustrative rates only)

The following example uses illustrative figures. Actual rates will vary by provider and applicant.


— £80,000 drawn for 8 months

— £30,000 drawn for 4 months

Interest calculation:

— 8 months at £80,000: £80,000 × 1.2% × 8 = £7,680

— 4 months at £30,000: £30,000 × 1.2% × 4 = £1,440

Total interest for the year: £9,120

— Average drawn balance over 12 months: (£80,000 × 8 + £30,000 × 4) ÷ 12 = £63,333

Comparison — equivalent term loan:

A term loan of £120,000 (approximate annual average) at the same illustrative rate of 1.2% per month, with interest calculated on the full outstanding balance throughout the year:

— £120,000 × 1.2% × 12 = £17,280

The revolving facility costs £9,120 against £17,280 for a comparable term loan — a saving of £8,160 — because interest accrues only on what is drawn at any given time. The facility charges you for capital you actually use, not capital you hold in reserve.

This is the core economic argument for a revolving credit facility over a term loan for working capital purposes: you pay for utilisation, not availability.

When evaluating providers, ask for a full schedule of all fees — arrangement, facility, and draw fees — and model total cost for your own projected utilisation. A lower headline rate with a high facility fee may cost more in aggregate than a slightly higher rate with no facility fee, depending on your draw-down behaviour.

5. Covenants and facility review triggers

Covenant structure is a material consideration when selecting a credit facility — particularly for CFOs who need to avoid triggering restrictions that limit operational flexibility.

Financial covenants are contractual ratios or thresholds — leverage ratios, interest cover, minimum net asset values — that the borrower must maintain. A breach triggers a covenant event, which can give the lender the right to demand repayment, adjust pricing, or withdraw the facility.

Traditional bank revolving credit facilities for SMEs often carry financial covenants tested quarterly or annually. Maintaining compliance requires ongoing monitoring and can constrain strategic decisions — for example, deferring a capital expenditure to protect an EBITDA covenant.

Annual review triggers. Most facilities include an annual review, at which the lender reassesses the facility limit and terms. A material deterioration in trading performance or credit metrics at review point can result in a limit reduction or pricing adjustment, even within a committed term.

Specialist lenders vs banks. Specialist lenders typically operate with lighter covenant structures than clearing banks. This is a meaningful differentiator for SMEs: fewer restrictions on operational decisions, less administrative overhead in compliance reporting, and reduced risk of technical covenant breaches arising from accounting adjustments rather than underlying business deterioration.

Before signing any facility agreement, your legal and finance teams should review the covenant package in detail. Understand exactly which metrics are tested, how frequently, and what the cure rights are in the event of a breach.

6. Integrating a credit line into cash flow forecasting

A revolving credit facility is most valuable when it is actively managed — not held as a passive backstop. Integrating it properly into your 13-week cash flow forecast gives your finance team a dynamic lever to optimise working capital.

Model the facility as a line item. In your weekly cash flow model, include a dedicated row for facility drawdowns (cash in) and repayments (cash out). This makes the facility’s impact on net cash position visible and allows you to model different draw scenarios.

Drawdown as a lever. When the 13-week forecast shows a cash shortfall in weeks 4–6 due to a large creditor payment ahead of anticipated receivables, you can schedule a drawdown to cover the gap. When a large customer payment lands in week 7, you schedule repayment. The facility absorbs the timing mismatch without affecting operating decisions.

Repayment timing optimisation. Because there are no early repayment penalties with Juice Flex, the finance team can repay as soon as surplus cash is available — minimising the interest-accruing drawn balance. Modelling this in the forecast quantifies the interest saving from early repayment versus holding cash on deposit.

Scenario planning. Build at least three scenarios: base case (expected receivables timing), downside (30-day delay on key receivables), and stress (60-day delay). For each scenario, model the maximum required drawdown against available facility limit. This tells you whether your current facility size is adequate for your risk envelope.

Covenant headroom monitoring. If your facility carries financial covenants, integrate covenant headroom tracking into the same model. Flag weeks where projected performance could approach a covenant threshold — giving management time to respond before a breach occurs.

7. Accounting treatment of a revolving credit facility

This is a general overview only. Consult your auditor or accountant for treatment specific to your business.

Balance sheet classification. The drawn balance of a revolving credit facility appears as a financial liability on the balance sheet. Whether it is classified as current (due within 12 months) or non-current (due after 12 months) depends on the maturity of the facility. A 12-month revolving facility will typically be classified as a current liability. A multi-year facility may be classified as non-current, subject to the terms and any demand provisions.

Undrawn commitment. The undrawn portion of the facility limit does not appear on the balance sheet as a liability — it is a contingent facility. It may be disclosed in the notes to the financial statements as an available but undrawn borrowing facility.

Interest accrual. Interest on the drawn balance accrues daily and is recognised as a finance cost in the income statement. The accrued but unpaid interest at period end appears as an accrued liability on the balance sheet.

Arrangement fees. Arrangement fees and other directly attributable transaction costs are typically capitalised and amortised over the life of the facility under IFRS 9 and FRS 102. They are not expensed immediately. The treatment should be confirmed with your auditor.

Covenant breaches. If a covenant breach occurs and the facility becomes repayable on demand, the liability may be reclassified from non-current to current — a material balance sheet impact. Covenant monitoring is therefore not only a treasury risk issue but an accounting presentation issue.

8. Line of credit vs overdraft: a treasury perspective

For many UK SMEs, the bank overdraft has been the default working capital tool. From a treasury perspective, a revolving credit facility is structurally superior in several respects — but the comparison is worth making explicitly.

The overdraft’s key weakness is its uncommitted nature. A lender can reduce or withdraw an overdraft at annual review, or earlier if trading conditions deteriorate. For a CFO building a working capital plan, relying on an uncommitted facility introduces treasury risk that is difficult to hedge.

The term loan’s weakness for working capital purposes is its fixed repayment structure. Paying interest on £500,000 when you only need £150,000 at a given point in the cycle is an avoidable cost. A revolving facility eliminates this through its pay-for-utilisation model.

A revolving credit facility is also typically independent of the borrower’s main banking relationship. This is a meaningful consideration: if you need to switch banks, your revolving facility does not move with the banking relationship. Your working capital facility remains stable regardless of changes to your primary banking arrangements.

9. What to look for when evaluating providers

The headline interest rate is one input — but a rigorous evaluation of a revolving credit facility provider should cover several additional dimensions.

Committed vs uncommitted. Confirm in writing whether the facility is committed for the term. This is non-negotiable for a facility you intend to rely on for working capital planning.

Drawdown speed. How quickly are approved drawdowns funded? For working capital purposes, same-day or next-business-day funding is typically required. A facility that takes three to five days to fund defeats the purpose of having flexible capital access.

Covenant intensity. Review the covenant package carefully. Fewer covenants — or none — reduces administrative burden and the risk of technical breaches. Specialist lenders typically operate with lighter covenant structures than clearing banks.

Total cost of funds. Model the full fee structure — arrangement, facility, and draw fees — against your anticipated utilisation pattern. Do not compare headline rates in isolation.

Early repayment. Confirm there are no early repayment penalties. A facility with break costs constrains your ability to optimise the drawn balance dynamically. Juice Flex carries no early repayment penalties.

Renewal and review terms. Understand exactly what triggers a facility review and what the renewal process involves. A facility that is difficult to renew or that comes with significant renegotiation risk at annual review provides less certainty than its committed status implies.

Reporting requirements. Some lenders require regular management accounts, covenant compliance certificates, or other periodic reporting. Factor this into the administrative cost of the facility — particularly for finance teams operating with limited headcount.

Juice Flex is a revolving credit facility offering £50,000 to £1,000,000 for UK SMEs. Subject to status and lending criteria. No early repayment penalties.
