A revolving credit facility is one of the most flexible forms of business finance available in the UK, yet it is also one of the most misunderstood. Many business owners either overlook it entirely or confuse it with a standard business loan. Understanding how it actually works could save you money and give your business a meaningful financial cushion.
What Is a Revolving Credit Facility?
A revolving credit facility (often called an RCF) is a pre-agreed borrowing limit that you can draw down, repay, and redraw repeatedly over the term of the agreement. Unlike a term loan, where you borrow a fixed lump sum and repay it on a set schedule, a revolving facility stays open. As you repay funds, they become available to borrow again.
Think of it as a financial reservoir. You only pay interest on what you have drawn, not on the full facility limit. This makes it fundamentally different in cost terms from holding a term loan you may not always need in full.
How Revolving Credit Differs From an Overdraft
Many business owners default to a bank overdraft when they need flexible short-term funding. An overdraft can work for small, occasional shortfalls, but revolving credit facilities tend to offer higher limits, clearer terms, and greater stability.
Key differences include:
- Overdrafts are typically repayable on demand; revolving facilities usually have fixed terms of 12 months to 3 years
- RCFs often come with a defined drawdown and repayment cycle, giving you more predictability
- Interest rates on revolving facilities can be more competitive for larger borrowing needs
- Overdrafts are almost exclusively offered by banks; revolving credit is available from a much wider range of lenders
The wider lender pool is significant. Non-bank and alternative lenders have grown considerably in the UK market, and many offer revolving facilities that high street banks simply do not match on speed or flexibility.
What Are the Costs Involved?
Costs on a revolving credit facility typically fall into two categories: commitment fees and utilisation interest.
A commitment fee is charged on the undrawn portion of your facility. It is usually a small percentage, often between 0.5% and 2% per annum, and it exists because the lender is reserving capital for you even when you are not using it. Some lenders waive this, so it is worth checking.
Utilisation interest is charged on the amount you actually draw down. Rates vary considerably depending on:
- Your business turnover and trading history
- The strength of your balance sheet and credit profile
- Whether the facility is secured or unsecured
- The lender and their appetite for your sector
Because rates vary so much between lenders, it genuinely pays to compare offers. A difference of even 1% to 2% on a facility you use regularly throughout the year adds up quickly.
When Does a Revolving Credit Facility Make Sense?
RCFs are best suited to businesses with recurring, short-term cash flow gaps rather than one-off capital needs. If you need to fund a single piece of equipment or a property purchase, other structures will almost certainly serve you better.
Common scenarios where revolving credit fits well:
- Seasonal businesses that need to stock up ahead of busy periods and repay after sales come in
- Businesses with long customer payment terms that need to bridge the gap between outgoing costs and incoming receipts
- Companies that take on project-based work and need to cover upfront costs before invoices are settled
- Importers managing currency and timing mismatches between paying suppliers and receiving goods
The flexibility also suits businesses in growth phases, where cash demands are unpredictable and having headroom without a formal drawdown request each time can make a real operational difference.
What Lenders Look At
Approval for a revolving credit facility is not simply about your credit score. Lenders take a broader view of your business.
Revenue consistency matters. Lenders want to see that money flows through your business regularly, because their repayment depends on it. A business with lumpy or declining revenue will face more scrutiny.
Existing debt levels are also examined carefully. If you already carry significant borrowing, a lender will assess whether adding a revolving facility creates an unmanageable obligation. This does not automatically disqualify you, but it affects the terms offered.
Some lenders will also look at your sector. Certain industries, particularly those seen as higher risk or with volatile margins, may face tighter conditions or higher pricing. This is another reason why approaching multiple lenders is practically useful: one lender's caution about your sector may not be shared by another.
Secured vs Unsecured Revolving Facilities
Revolving credit facilities can be structured as either secured or unsecured. Unsecured facilities are faster to arrange and require no specific asset as collateral, but limits are typically lower and rates higher.
Secured facilities, backed by property, receivables, or other business assets, can unlock larger limits at more competitive rates. Directors may also be asked to provide a personal guarantee, particularly for unsecured lending to smaller businesses. It is important to understand what you are committing to before signing.
What to Watch in the Small Print
Before committing to any revolving credit facility, read the terms carefully. Key things to look for:
- Minimum drawdown amounts and how often you can draw
- Notice periods required before drawing funds
- Prepayment penalties if you close the facility early
- Annual review clauses that allow the lender to reassess your limit or rate
- Any material adverse change clauses that could allow the lender to reduce or withdraw your facility
These clauses are common and not necessarily a problem, but understanding them means you will not be caught off guard.
The Takeaway
A revolving credit facility can be a genuinely powerful tool for UK businesses managing variable cash flow needs. The key is matching the structure to your actual funding pattern, understanding the full cost including commitment fees, and securing terms that reflect your business properly. Because pricing and appetite vary significantly across lenders, comparing multiple offers before committing is one of the most straightforward ways to make sure you are not overpaying for access to capital you may use regularly.
