Working Capital Loan vs Revolving Credit Facility for UK SMEs

A working capital loan gives UK SMEs a lump sum repaid over a fixed term, suited to one-off stock buys or planned payroll gaps. A revolving credit facility lets you draw, repay and redraw up to an agreed limit, paying interest only on what you use. Pick the loan for predictable spend, the facility for choppy cycles.

The core mechanical difference

A term loan deposits the full amount in your account on day one. You pay it back in equal monthly instalments, typically over 12 to 60 months, at a fixed or variable rate. A revolving credit facility behaves more like an overdraft sitting outside your current account. You have a ceiling, say £150,000, and you draw down whatever you need, when you need it. Interest only accrues on the drawn balance.

The practical effect on cash flow is significant. If your wholesaler offers 8% off for a £200,000 bulk order in February, a term loan funds it cleanly and the repayment schedule is set. If your payroll runs £80,000 some months and £140,000 others because of seasonal contractors, a facility lets you cover the spike without paying interest on idle funds the rest of the year. You can read our Working Capital definition for a refresher on what counts as working capital and why timing matters more than headline rate.

Cost structures compared

Pricing looks similar on paper but behaves differently in practice. A term loan quotes an Annual Percentage Rate (APR) covering interest plus arrangement fees. A revolving facility usually combines three charges: a non-utilisation fee on the unused portion (often 0.5% to 1.5% per year), interest on drawn funds, and an annual renewal or arrangement fee.

Run both scenarios through a business loan calculator before you commit. A £100,000 facility used at 40% average utilisation often costs less annually than a £100,000 term loan, but if you'll spend the full amount inside a month, the loan wins.

When a working capital loan fits better

Term lending suits SMEs with a defined funding need and a known repayment source. Think of a kitchen showroom buying £180,000 of display units before a Q4 sales push, or a printer financing a £75,000 machine upgrade ahead of a contract win. The total spend is fixed, the return is forecastable, and the monthly instalment slots into the budget.

Term loans also tend to suit businesses that prefer accounting simplicity. One drawdown, one schedule, one line in the cash flow forecast. According to the British Business Bank, term debt remains the most common external finance product among UK SMEs, partly because directors find it easier to model.

Typical use cases

• Bulk stock purchases tied to a peak season
• Refits, equipment, or marketing campaigns with a defined budget
• Funding a single large payroll month before a contract goes live
• Refinancing an expensive overdraft into structured repayments

For sole traders without ltd status, the criteria differ slightly. Our guide to Working Capital Loans for Sole Traders covers the documentation lenders ask for and how personal guarantees apply.

When a revolving credit facility wins

Facilities earn their keep when your funding need is lumpy or hard to predict. A recruitment agency paying contractors weekly while waiting 45 days for client invoices can draw on Monday, repay on Friday after a big client settles, and only pay interest for four days. That's structurally cheaper than carrying a term loan balance for 12 months.

Hospitality, events, and seasonal retail share the same pattern. December trading can swing cash positive by £200,000, then January wipes it out. A facility absorbs the swing without you constantly re-applying for credit. The Revolving Credit entry in our dictionary walks through the mechanics, including how covenants and headroom work.

Why facilities suit growth-stage SMEs

Businesses scaling from £2m to £10m turnover often outgrow overdrafts but aren't ready to commit to fixed monthly repayments. Revenue is climbing but uneven. A £250,000 facility with an easy revolving credit structure lets the finance director respond to opportunities, a sudden bulk discount, an unexpected hire, without renegotiating every time.

The discipline trap

Facilities reward discipline and punish drift. If your team treats the limit as working balance and never returns to zero, you pay interest year-round and the product behaves like an expensive term loan. Set internal rules: target utilisation under 60%, clear the balance twice a year, review covenants quarterly.

How lenders assess each product

Underwriting differs in emphasis rather than substance. Term loan applications focus on debt service coverage, can your trading profit comfortably cover monthly repayments with headroom of 1.25x to 1.5x? Lenders model the full repayment from day one and stress-test it against a revenue dip. Our affordability statement guide breaks down the exact ratios most UK lenders use.

Facility underwriting looks harder at volatility and quality of receivables. Lenders want to see that your peak draw is supported by inbound cash within a reasonable window. They'll ask for aged debtor reports, customer concentration analysis, and 13-week cash flow forecasts. Expect tighter covenants, minimum tangible net worth, maximum debt-to-EBITDA, quarterly compliance certificates.

Both products generally require:

• Two years of filed accounts (or management accounts for younger businesses)
• Last 6 to 12 months of business bank statements
• Up-to-date aged debtors and creditors
• Director personal guarantees for unsecured facilities under £250,000

For deals above £1m, the unsecured market thins out. Our page on the working capital loan at £1m level explains which lenders compete at that ticket size and what additional security or covenants typically apply.

Decision framework: which product, when

Map your funding need against three questions before applying.

1. Is the spend defined or fluid?

If you can write down the exact amount and the date you need it, lean term. If the figure could be anywhere between £40,000 and £160,000 depending on how Q3 unfolds, lean facility. Defined spend wastes money on a facility's non-utilisation fees. Fluid spend on a term loan means you either borrow too much and pay unnecessary interest, or borrow too little and scramble for top-ups.

2. How quickly does the spend convert to cash?

Stock that sells in 30 days behaves differently to a marketing campaign that pays back over 18 months. Short conversion cycles favour facilities, you draw, sell, repay, repeat. Long conversion cycles favour term loans matched to the payback period.

3. How comfortable are you with covenants?

Facilities almost always carry financial covenants tested quarterly. Breaching a covenant, even technically, can trigger a review, repricing, or withdrawal of the limit. If your management accounts aren't tight enough to monitor covenants in real time, a term loan with no ongoing tests may suit you better. Our Working Capital Loan Statistics page shows how covenant breach rates have moved over the last three years among UK SMEs.

Worked example: a £120,000 funding gap

A Bristol wholesaler forecasts a £120,000 working capital gap across the next 12 months. Stock buys cluster in March and September, £80,000 each. Payroll peaks in November at £45,000 over baseline. The rest of the year, the business runs cash positive.

Option A: 24-month term loan, £120,000 at 12% APR

• Monthly repayment: roughly £5,650
• Total interest over 24 months: about £15,600
• Cash sits idle from April to August and December to February

Option B: £150,000 revolving facility at 11% on drawn, 1% non-utilisation

• Average drawn balance across the year: about £55,000
• Interest on drawings: roughly £6,050
• Non-utilisation fee on average £95,000 undrawn: £950
• Annual fee: £1,500
• Total annual cost: about £8,500

The facility wins by roughly £7,000 a year in this scenario because the spend is genuinely lumpy. Reverse the assumption, all £120,000 needed in March and not recoverable until the following March, and the term loan becomes cheaper. Model both with the Revolving Credit Facility Calculator alongside a term equivalent before choosing.

Alternatives worth weighing

Neither product is the only option. Invoice finance unlocks cash from unpaid sales ledger, which can be cheaper than either a loan or a facility if your debtor book is strong. Our comparison of Invoice Finance Versus Working Capital Loans for Growing SMEs sets out when receivables-backed funding beats unsecured debt.

Asset finance fits capital expenditure better than either. Merchant cash advances suit very short-cycle retail and hospitality with strong card takings. For Irish-registered subsidiaries or cross-border traders, the rules differ, see our notes on Working Capital Loans Ireland.

Lender choices in the UK market

The UK alternative lending market has roughly 40 active providers offering one or both products. Pricing varies more than headline rates suggest once you factor in fees, prepayment terms, and covenant tightness. Reviews of specific lenders, such as E-Capital and Inhale Capital, give you a sense of where each sits on speed, flexibility, and security requirements.

High street banks remain competitive on price for established borrowers with two years of profitable trading. Alternative lenders win on speed, often funding in 5 to 10 working days against 6 to 12 weeks for a bank, and on willingness to lend against weaker balance sheets. The FCA consumer credit register is worth checking before signing with any non-bank lender.

Practical next steps

Start by mapping your next 12 months of cash flow week by week. Identify the troughs and their causes. If you find one or two large defined gaps with predictable timing, get quotes on a business working capital loan at the size you actually need, not rounded up. If you see five or six smaller swings with uncertain timing, price a facility instead.

Then run the numbers properly. Use the Working Capital Loan Calculator to model the term option, and price the facility on realistic average utilisation, not best case. Get at least three quotes. Compare total cost of credit over 12 months, not headline APR. Check early repayment terms on the loan and covenant definitions on the facility.

Finally, match the product to your finance team's bandwidth. A term loan needs little ongoing attention once drawn. A facility needs monthly utilisation reviews and quarterly covenant checks. Pick the structure your business can actually manage, not just the one that looks cheapest on a spreadsheet.
