Working capital finance covers the range of short-term funding solutions UK businesses use to bridge the gap between paying suppliers and receiving payment from customers. In 2026, UK businesses use invoice finance, business overdrafts, revolving credit facilities, and short-term loans to manage cash flow timing – each with different costs, eligibility criteria, and implications for your balance sheet.
- Invoice factoring costs 0.5-3% per month - Plus service fees of 0.75-2.5% of turnover, making it expensive for high-volume businesses
- Asset-based lending offers up to 85% of asset value - Secured against inventory or equipment, providing larger funding amounts than unsecured options
- Bank overdrafts remain cheapest at 6-15% APR - But approval rates dropped 23% in 2023, forcing businesses toward alternative finance providers
- Trade credit periods average 30-60 days in UK - Negotiating extended terms with suppliers can reduce working capital requirements by 15-25%
- Alternative lenders approve 67% faster than banks - Decision times of 24-48 hours versus 4-6 weeks for traditional bank facilities
What Is Working Capital Finance?
Working capital finance is any form of short-term funding used to cover day-to-day business operations – paying staff, suppliers, and expenses while waiting for customer payments to arrive. Unlike long-term finance (business loans, commercial mortgages), working capital finance is designed to be drawn and repaid quickly as cash flows in and out. The most common forms are: business overdrafts, revolving credit facilities, invoice finance (factoring or discounting), and short-term business loans.
Types of Working Capital Finance
The main types of UK working capital finance are: invoice finance (release cash from unpaid B2B invoices – scales with sales); business overdraft (revolving facility on your bank account, draw and repay as needed, interest only on amount used); revolving credit facility (similar to an overdraft but available independently of your main bank); short-term business loan (fixed lump sum for 1–18 months, useful for seasonal stock purchases or specific cash flow gaps); and trade finance (letters of credit and import loans for businesses purchasing from overseas suppliers).
| Product | Best For | Typical Cost | Repayment |
|---|---|---|---|
| Invoice finance | B2B with slow-paying customers | 2–5% of annual turnover | When customers pay invoices |
| Business overdraft | Recurring short-term cash gaps | 7–13% EAR on drawn balance | Revolving – repay as cash comes in |
| Revolving credit facility | Flexible ongoing working capital | Similar to overdraft | Draw/repay within agreed limit |
| Short-term loan | Specific, time-limited cash need | 10–50% APR | Fixed monthly over 3–18 months |
| Trade finance | Import/export stock purchases | 2–6% of facility | On shipment/receipt |
How to Choose the Right Working Capital Solution
Match the working capital product to the root cause of your cash flow problem. If the problem is unpaid invoices from business customers: invoice finance. If it is recurring timing gaps between payroll and customer payments: overdraft or revolving credit. If it is a seasonal stock purchase: short-term loan. If it is payment terms to overseas suppliers: trade finance. Using the wrong product – such as a long-term overdraft to fund a capital purchase – is expensive and creates refinancing risk when the overdraft is recalled.
Working Capital Finance Costs
Invoice finance (factoring or discounting) is typically the most cost-effective working capital solution for B2B businesses with significant unpaid invoice ledgers – total annual cost is 1–5% of turnover. Overdrafts are efficient for short-duration cash gaps (cost is low if repaid quickly; expensive if continuously drawn). Short-term loans carry higher rates (10–50% APR) but provide certainty for defined cash needs. The overall cost depends on how long you need the funding – products with low headline rates but long drawdown periods accumulate more total interest than faster, cheaper products used briefly.
Choosing the Right Working Capital Solution
Choose an overdraft for short-term, unpredictable cash flow gaps (repayable on demand, flexible). Choose invoice finance if your cash flow problem is driven by slow-paying customers (turns receivables into immediate cash). Choose a revolving credit facility for planned, recurring needs above overdraft limits. Choose a business loan for specific one-off investments or expenditure where you know the exact amount needed. Most growing businesses use a combination – typically an overdraft for day-to-day fluctuations alongside invoice finance for their receivables ledger.
The cost of working capital finance varies significantly by type. Overdrafts are the most expensive per-pound-borrowed (base rate + 3–8%) but cheapest overall if usage is minimal and sporadic. Invoice finance is cost-effective for businesses with large receivables ledgers and extended payment terms. Business loans offer the lowest fixed rate for planned expenditure but lack the flexibility of revolving facilities. Always compare the total annual cost across options rather than headline rates alone.
