Revolving Credit Facilities: What Is a Revolving Credit Facility?
Borrowing You Can Dip Into, Repay, and Use Again
Money coming in and money going out rarely line up neatly. Bills arrive before customers pay, stock needs buying before it sells, and quiet months follow busy ones. A revolving credit facility, often shortened to RCF, is a type of business borrowing built for exactly that kind of unevenness.
Rather than taking a single lump sum, you get an agreed limit you can draw from when you need it, repay when cash arrives, then draw from again. This guide explains how that works in practice, in plain English.
Is This the Right Read for You?
This is written for UK business owners, directors, and finance managers who want to understand revolving credit before speaking to a lender. It will be most useful if your income is seasonal, your customers pay on long terms, or you simply want a safety net for working capital rather than a one-off lump sum.
What a Revolving Credit Facility Actually Is
A revolving credit facility is a pre-agreed pool of credit that your business can borrow from, repay, and borrow from again without submitting a fresh application each time. The British Business Bank compares it to an overdraft or a credit card: once you have repaid what you drew, that headroom becomes available again. The key phrase to hold onto is reusable borrowing capacity.
Terms are usually short to medium in length. UK guidance commonly describes facilities running from around three months up to two years, with some lenders offering 24 or even 36 months depending on the business and its risk profile. Extensions and rolling renewals are possible, but they are not automatic.
Facility sizes vary enormously. Some UK providers advertise limits from around £50,000 up to £1 million, while others arrange multi-million-pound facilities for larger companies. Turnover, trading history, sector, and any security offered all influence where you land.
An RCF is not a lump sum you repay over years. It is a credit line you keep coming back to.
How It Works Day to Day
Once your facility is agreed, you sign a facility agreement setting out the limit, the term, the interest rate, any fees, and any conditions the lender attaches. From that point you draw down funds as and when you need them, often through an online portal or by request to your relationship manager.
Crucially, most UK lenders charge interest only on the amount you have actually drawn, not on the full approved limit. Some calculate interest daily on the outstanding balance, which means a short draw of a few days costs far less than holding the money for months. Repayments may be structured daily, weekly, or monthly depending on the provider.
As you repay the principal, the limit replenishes. So a business with a £200,000 facility that draws £80,000 to buy stock and repays it once the stock sells is back to £200,000 of available headroom. That cycle can repeat as often as your cash conversion allows, right up until the facility term ends and renewal is discussed.
Why Businesses Choose Them
The appeal is timing. UK lenders consistently position revolving credit as a working capital tool for bridging the gap between paying costs and receiving revenue. If you invoice on 60-day terms but pay staff and suppliers weekly, that gap is a permanent feature of your business, not a one-off problem.
An RCF lets you borrow in stages rather than all at once, which keeps interest costs tied to actual need instead of a worst-case estimate. It also reduces the temptation to hold large cash reserves purely as a buffer, freeing that money for growth.
Compared with a bank overdraft, an RCF is usually more structured and formally negotiated. There is a separate facility agreement, an agreed limit, and a defined term. That gives clearer visibility over what funding is available and for how long, which is helpful when planning. The trade-off, as we cover below, is that this structure can come with tighter conditions than a simple overdraft.
Seasonal retailers, construction firms, recruitment agencies, and manufacturers building inventory are all common users.
Weighing Up the Trade-Offs
| Potential advantages | Potential drawbacks |
|---|---|
| Draw, repay, and reuse funds without reapplying | Terms are usually time-limited, so renewal needs planning |
| Interest typically charged only on what you draw | Arrangement fees and non-utilisation fees can add real cost |
| Clear, negotiated limit gives planning certainty | May require security such as a debenture or personal guarantee |
| Matches borrowing to your working capital cycle | Covenants and ongoing reporting may apply |
| Cheaper than holding a large cash buffer | Limits depend on your profile, not simply what you need |
| More structured and visible than an overdraft | Lenders can review, reduce, or decline renewal |
The Details That Change the Real Cost
The headline interest rate rarely tells the whole story. UK lender and broker pages point to arrangement or setup fees of roughly 1% to 5% of the facility limit, which is charged whether or not you draw a penny. Some facilities also carry a non-utilisation fee on the undrawn portion, effectively a charge for keeping the headroom available.
Security is the other area to examine closely. Depending on the lender and your circumstances, an RCF may be secured by a debenture over company assets, an assignment of receivables, or a personal guarantee from directors. A personal guarantee moves risk from the company to you individually, so it deserves careful thought and, ideally, independent legal advice.
Also check the review and renewal mechanics. Facilities can be reviewed periodically, and covenant breaches or a downturn in trading may lead to a reduced limit or a decision not to renew. Ask what happens at the end of the term and how much notice you would receive.
Compare the all-in cost, not the advertised rate.
Other Options Worth Comparing
- Business overdraft - simpler and often quicker to arrange, usually attached to your current account. Less structure, but typically smaller limits and repayable on demand.
- Term loan - a fixed lump sum repaid over a set schedule. Better suited to one-off capital projects, equipment, or acquisitions than to fluctuating working capital.
- Invoice finance - borrowing against specific unpaid invoices rather than a general limit. Useful if long debtor days are the core problem and your sales ledger is strong.
- Asset finance - spreads the cost of vehicles, machinery, or equipment over its useful life, with the asset itself usually providing the security.
- Business credit card - practical for smaller, frequent expenses and short repayment cycles, though limits and rates rarely suit larger working capital needs.
- Merchant cash advance - repayments flex with card takings, which can suit retail and hospitality, but costs should be compared carefully.
- Supplier or trade credit - negotiating longer payment terms with suppliers can sometimes solve a timing gap without borrowing at all.
Common Questions
Is a revolving credit facility just a bigger overdraft? Not quite. Both let you borrow, repay, and reborrow, but an RCF sits under its own facility agreement with an agreed limit, a defined term, and negotiated conditions. That usually means more structure and visibility, and sometimes tighter covenant, security, or renewal requirements.
Do I pay interest on the whole limit? Generally no. UK lenders typically charge interest only on the amount drawn, often calculated daily. However, arrangement fees and non-utilisation fees on the undrawn balance may still apply, so always ask for the total cost.
How long does an RCF last? Commonly between three months and two years, with some lenders offering up to 24 or 36 months. Extensions and rolling renewals exist but depend on your repayment record and continued eligibility.
How much could I borrow? It varies widely. Some UK providers advertise from around £50,000 to £1 million, while larger facilities run into millions. Turnover, trading history, sector, and available security all influence the outcome.
Will I need to give security or a personal guarantee? Sometimes. A debenture, receivables assignment, or director's personal guarantee may be required depending on the lender and your business profile. Read these terms carefully before signing.
What happens when the term ends? The facility may be renewed, restructured, reduced, or withdrawn. Because renewal is not guaranteed, it is sensible to plan ahead rather than assume continuity.
