Secured business finance is borrowing backed by a specific asset, usually property, equipment or vehicles, that the lender can take and sell if the business does not repay. Unsecured business finance has no such asset behind it; the lender relies on the business's cash flow and, for limited companies, a personal guarantee from the directors. Secured borrowing is generally cheaper, larger and longer, but slower to arrange and riskier for the asset owner. Unsecured borrowing is faster and keeps assets free, but costs more and is capped at smaller amounts. The rest of this guide sets out the differences in detail.
The two options compared
| Feature | Secured business finance | Unsecured business finance |
|---|---|---|
| Security | A legal charge over property, plant, vehicles, stock or receivables, or a debenture over the company's assets as a whole. | None over specific assets. The lender relies on trading performance and credit history. |
| Typical term | Three to 25 years, depending on the asset. Commercial mortgages sit at the long end, equipment finance at the short end. | Six months to five years. Many products run for one to three years. |
| Typical cost | Lower interest rates because the lender's loss is limited if things go wrong. Valuation, legal and arrangement fees add to the upfront cost. | Higher interest rates or factor rates to reflect the lender's greater risk. Fees are usually simpler but can still be material. |
| Speed | Several weeks to a few months. Valuations, title checks and legal work take time. | Days to two weeks is common once documents are supplied. |
| Amounts | Driven by the asset's value. Six- and seven-figure facilities are possible with suitable security. | Driven by turnover and affordability. Facilities are often capped at a proportion of annual revenue. |
| What is at risk | The secured asset itself, which may be the trading premises or the owner's home. | The business's credit standing and, through a personal guarantee, the guarantor's personal assets. |
| Personal guarantees | Sometimes required alongside the security, particularly where the asset's value does not fully cover the loan. | Standard for limited-company borrowing. Sole traders are already personally liable. |
What counts as security?
Security is a legal right over an asset that lets the lender sell it to recover the debt. For business lending it is most often a first or second charge over commercial or residential property, a fixed charge over specific equipment or vehicles, or a floating charge over changing assets such as stock and book debts. A debenture combines fixed and floating charges across the whole company.
Lenders value security conservatively. A property worth £400,000 might support borrowing of £260,000 to £300,000, and a second charge behind an existing mortgage supports far less. Our secured business loans page explains how lenders assess different asset types, and asset-based lending covers facilities built around receivables, stock and plant.
Why unsecured finance costs more
With no asset to fall back on, an unsecured lender prices for the chance that the business fails and little is recovered. That shows up as a higher interest rate, a shorter term that limits the lender's exposure, and a lower maximum amount. It also shows up as a personal guarantee, which transfers some of that risk to the director. The guarantee is what makes "unsecured" a slightly misleading word: the business's assets are not pledged, but the director's may be reachable.
For sole traders and small partnerships borrowing up to £25,000, the agreement is regulated under the Consumer Credit Act, which brings additional protections around information, affordability and complaints. Limited companies and LLPs generally sit outside that regime, so the agreement's own terms carry more weight. The unsecured business loans page covers eligibility and typical terms in more detail.
The trade-off: cheaper rate or asset at risk
The heart of the decision is simple. Security lowers the cost of borrowing because it lowers the lender's risk. It does that by moving the risk onto the asset owner. A commercial mortgage at a modest rate over 15 years is far cheaper per pound than an unsecured loan over three years, but if trading falls away the premises can be repossessed. An unsecured loan is dearer, yet a failure leaves the premises intact and the fallout confined to the company and the guarantor.
Three factors usually settle it. First, how confident you are in the repayments: security is only cheap if you keep paying. Second, whose asset it is: securing a loan on the company's own freehold is a different proposition from securing it on a director's family home. Third, the size and term of what you need: large, long-term borrowing is rarely available unsecured at any price, so the question answers itself.
An illustrative comparison
Suppose a company needs £150,000. A secured loan over ten years at a lower rate might cost around £1,700 a month, and the total interest over the term might be in the region of £55,000. An unsecured loan over four years at a higher rate might cost around £3,900 a month, with total interest of perhaps £37,000. The unsecured route costs less in total interest because the money is borrowed for a shorter time, but the monthly payment is more than double, and the amount may not be available unsecured at all. These figures are illustrative only and not a quote; actual rates depend on the business and the provider.
Scenarios
A profitable company refinancing expensive short-term debt
A business with several high-cost facilities and a freehold unit may use a secured loan to consolidate its business debt at a lower rate over a longer term. The monthly outgoing falls and the total interest may fall too, but the unit is now at risk and an unsecured problem has become a secured one.
A service business with no significant assets
A consultancy or agency with strong receivables but no property has little to offer as security. Unsecured borrowing or invoice finance is the realistic route, sized to the need and kept as short as cash flow allows.
A business needing money quickly
Where a supplier payment or tax deadline is days away, a secured facility will not complete in time. An unsecured facility can, at a higher cost. Borrowing quickly to meet HMRC is a decision to take with care; a Time to Pay arrangement may be the cheaper option and is described on our HMRC tax debt page.
A business with a weaker credit history
Where past missed payments or County Court judgments limit unsecured options, security can open doors that would otherwise stay shut. It can also make the cost of a poor history painfully clear, as the guide Can a business refinance with bad credit? explains.
Before you offer your home as security
Securing company borrowing on a director's home means that if the company fails, the lender may take possession of the property. Independent legal advice is usually required and is always sensible. If the business is already struggling to pay its debts as they fall due, adding security rarely fixes the underlying problem, and free impartial advice from Business Debtline should come before any new agreement.
Questions to settle before choosing
- How much do we need, and for how long? Large and long points to secured.
- What assets exist, who owns them, and are they already charged to someone else?
- What is the total cost of each route, including valuation, legal and arrangement fees, not just the rate?
- Will a personal guarantee be required either way, and is it capped?
- Are there early repayment charges if the business can clear the debt sooner?
- Can the repayments be met in a poor trading quarter, not just a good one?

Key takeaways
- Secured finance is backed by a specific asset; unsecured finance relies on cash flow and usually a personal guarantee.
- Security lowers the rate and raises the available amount and term, at the cost of putting the asset at risk.
- Unsecured finance is faster and leaves assets free, but costs more and is limited to smaller sums over shorter terms.
- A lower rate over a longer term can still mean more interest in total; compare both figures.
- Never secure borrowing on a home, or sign a guarantee, without independent advice and a realistic affordability test.
