Quick answer
Popular business finance guides
A secured business loan is backed by property or assets, offering larger amounts (£25k–£2m+) at lower rates (around 6–12% APR), but the asset is at risk and approval is slower. An unsecured loan needs no security, funds faster (24–48 hours) and risks no asset (though a personal guarantee may apply), but is smaller (£5k–£500k) and priced higher (around 8–25% APR). The right choice depends on the amount, your assets and how quickly you need funds.

Updated July 2026 — rates and figures in this guide were checked on 12 July 2026 against the Bank of England base rate (3.75%) and published UK lender pricing. Connection Technologies is an FCA-authorised credit broker, not a lender (FRN 958225).
- Secured loans use an asset as collateral, unlocking larger sums and lower rates but putting that asset at risk.
- Unsecured loans need no collateral, are faster to arrange, but cost more and usually require a personal guarantee.
- The right choice depends on the amount, how fast you need it, and how much risk you can carry.
- Hybrid and part-secured structures exist for borrowers who fall between the two.
- Loan interest is generally an allowable business expense, whichever structure you choose.
One of the first choices you face when borrowing is the structure of the loan. Getting secured vs unsecured business loans right can save you money and protect your assets. This guide compares the two on cost, speed, amount and risk, and helps you pick, with links to the broader business loans market.

The core difference
A secured loan is tied to an asset you own, such as commercial property, equipment or stock. If you default, the lender can recover the debt from that asset. An unsecured loan has no such charge, so the lender relies on your trading strength and often a personal guarantee instead.
How they compare
- Amount: secured loans reach much higher, often £25,000 to £2m or more; unsecured loans typically cap around £500,000.
- Rate: secured loans are usually cheaper because the lender’s risk is lower.
- Speed: unsecured loans are faster, with no asset valuation; decisions can come within 24 hours.
- Risk: secured loans put a named asset on the line; unsecured loans rely on a guarantee.
- Term: secured loans can run longer, spreading repayments further.
When a secured loan makes sense
Choose secured borrowing when you need a large sum, want the lowest rate, or are funding a major investment like premises or heavy equipment. It also helps if your credit is weaker, because the asset offsets the lender’s risk, as covered in our bad credit business loans guide.
When an unsecured loan makes sense
Choose an unsecured business loan when speed matters, the amount is moderate, or you simply do not want to risk an asset. It is the most flexible option for everyday needs like cash flow, stock and marketing, and it suits newer or asset-light businesses.
What about personal guarantees?
Many unsecured loans require a director’s personal guarantee. This is not the same as securing the loan against a specific asset, but it does mean you are personally liable if the business cannot repay. Always read the guarantee terms before signing.
Cost over time
A lower secured rate can save thousands over a long term, but the savings only matter if you are comfortable pledging the asset. For shorter, smaller borrowing, the speed and simplicity of unsecured finance often outweigh a slightly higher rate. Model both on our business loan calculator before deciding.
How to choose
- Size the need. Large investment leans secured; everyday cash flow leans unsecured.
- Weigh the risk. Only pledge an asset you are willing to lose in a worst case.
- Factor in speed. If you need funds this week, unsecured wins.
- Compare total cost, not just the headline rate.
- Get whole-of-market quotes so you can see both side by side.
Two quick scenarios
Seeing the choice in context makes it clearer.
Scenario one: buying premises
A profitable firm wants £400,000 to buy its own unit. A secured loan against the property offers a low rate over a long term. Here, secured borrowing is the natural fit, because the sum is large and the asset is the very thing being financed.
Scenario two: a marketing push
A growing agency needs £30,000 for a three-month campaign and wants it this week. An unsecured loan is ideal: fast, no asset at risk, and repaid before the next financial year. Securing a small, short loan against property would be overkill.
What assets can secure a loan?
Secured lenders accept a range of collateral, including:
- Commercial or residential property.
- Plant, machinery and vehicles.
- Stock and inventory.
- Outstanding invoices, via invoice finance.
The asset’s value and how easily it can be sold both affect how much you can borrow against it.
What happens if you cannot repay?
This is the heart of the risk difference. With a secured loan, the lender can ultimately take and sell the pledged asset to recover the debt. With an unsecured loan, there is no specific asset to seize, but if a director has given a personal guarantee, they become personally liable. Either way, missed payments harm your credit, so borrow only what you can comfortably repay.
Other finance types to consider
Secured and unsecured term loans are not your only choices. Depending on the need, also weigh:
- Overdrafts for short-term, flexible cash flow.
- Asset finance for equipment and vehicles.
- A merchant cash advance for card-reliant businesses — see how a merchant cash advance works.
- The Growth Guarantee Scheme for better terms on viable lending.
How lenders value your security
When you offer an asset, the lender does not simply take its market value. They apply a discount, often called a loan-to-value ratio, to allow for the cost and uncertainty of selling it if things go wrong. Property might secure borrowing up to around 70% of its value, while specialist equipment, which is harder to resell, may secure far less.
The asset’s stability matters too. A commercial building in a strong location is attractive collateral, whereas fast-depreciating stock is weaker. Understanding this helps you judge how much a given asset can realistically unlock and why secured offers sometimes come in lower than owners expect.
Is loan interest tax-deductible?
For most UK businesses, interest on a loan taken out for genuine business purposes is an allowable expense, which reduces taxable profit. The capital you repay is not deductible, only the interest and certain associated costs. This applies broadly to both secured and unsecured business loans.
The treatment can vary with your structure and circumstances, so always confirm the position with your accountant before relying on it. Even so, the deductibility of interest means the effective cost of borrowing is often lower than the headline rate suggests.
Terms people often confuse
A few terms trip business owners up. A secured loan is charged against a specific asset. A personal guarantee makes an individual liable but does not name an asset. A debenture is a broader charge a lender may take over a company’s assets. And asset finance is not the same as a secured loan; it funds a specific item, which itself acts as the security. Knowing the difference helps you read offers accurately and avoid pledging more than you intend.
Five questions to ask before you choose
Cutting through the detail, your decision usually comes down to five honest questions. Working through them turns an abstract comparison into a clear answer for your business.
- How much do I actually need? Larger sums push you towards secured borrowing; moderate amounts sit comfortably with unsecured.
- How fast do I need it? If funds are needed this week, unsecured almost always wins on speed.
- Do I have an asset I am willing to risk? Only pledge collateral you could bear to lose in a genuine worst case.
- How strong is my credit? Weaker credit often makes secured borrowing more accessible and better priced.
- How long do I want to repay over? Secured loans can stretch further, lowering monthly cost but raising total interest.
There is rarely a single right answer for every business, only the right answer for yours. A profitable, asset-rich company funding a major purchase leans naturally to secured borrowing. A nimble, asset-light firm that values speed and flexibility leans to unsecured. Run both options through a calculator, weigh the total cost against the risk you are comfortable carrying, and the sensible choice usually becomes obvious. If it does not, that is a good sign you should get whole-of-market quotes and compare the genuine offers side by side rather than deciding in the abstract.
The bottom line
Secured and unsecured loans are not better or worse than one another; they are tools for different jobs. Secured borrowing trades the risk of an asset for larger sums and lower rates, making it the right choice for major, long-term investment. Unsecured borrowing trades a slightly higher rate for speed, simplicity and peace of mind, which suits everyday needs and asset-light businesses. Decide what matters most for this particular borrowing, then compare real offers across the market before you commit — if you are new to borrowing, start with how business loans work.
Costs side by side: a worked comparison
Numbers make the secured versus unsecured decision concrete. Imagine borrowing £100,000 over five years. The figures below are illustrative for 2026 and show why rate and structure matter so much.
| Feature | Secured | Unsecured |
|---|---|---|
| Indicative APR | around 6–10% | around 9–25% |
| Collateral | Property or equipment | None (guarantee likely) |
| Time to fund | 1–4 weeks | 1–2 days |
| Typical maximum | Tied to asset value | Often 1–2 months’ turnover |
Over the full term, even a few percentage points of APR can mean thousands of pounds — see current UK business loan interest rates. The cheaper secured rate is only worth it, though, if you can carry the risk to the asset.
Hybrid and part-secured loans
The choice is not always binary. Some lenders offer part-secured facilities, where a portion is backed by an asset and the rest sits unsecured. This can blend a competitive rate with a manageable level of risk.
These structures suit businesses that own a useful but modest asset — say equipment rather than property. They are worth raising with a broker who can see the whole market rather than a single lender’s range.
How debentures and fixed or floating charges work
When a company borrows on a secured basis, the lender often registers a debenture at Companies House. This sets out their claim over company assets if things go wrong.
A fixed charge covers a specific asset such as a building, while a floating charge covers changing assets such as stock. Knowing which charge applies tells you exactly what is on the line, so always read this part of the agreement closely.
Refinancing from unsecured to secured
Many businesses start with fast unsecured borrowing, then refinance onto a cheaper secured loan once they own an asset or have grown. Done well, this cuts the monthly cost and frees up cash flow.
Watch for early-repayment charges on the original loan, and make sure the savings outweigh any arrangement fees on the new one. Refinancing only makes sense if the total cost genuinely falls.
Five questions to settle before you decide
Use these to cut through the comparison quickly:
- How much do I need, and does an unsecured lender go that high?
- How fast do I need the funds?
- Do I own an asset I am willing to pledge?
- Could I keep paying if a key customer left tomorrow?
- What is the total repayable, not just the monthly figure?
If you decide unsecured is the better fit, our guide to unsecured business loans explains how to apply.
Glossary of secured-lending terms
- Collateral: an asset pledged to back the loan.
- Debenture: a registered charge over company assets.
- Loan-to-value: the loan size as a percentage of the asset’s worth.
- Personal guarantee: a director’s promise to repay personally.
- Default: failing to meet the agreed repayment terms.
Which assets make the best security
Not every asset is equally useful as collateral. Lenders prefer things that are easy to value and sell. The table ranks the common options.
| Asset | Lender appetite | Note |
|---|---|---|
| Commercial property | Strong | Highest loan-to-value, lowest rates |
| Plant and machinery | Good | Valued on resale, not purchase price |
| Vehicles | Moderate | Depreciation limits the advance |
| Debtor book | Moderate | Often funded via invoice finance instead |
The stronger the asset, the better the terms. Property routinely unlocks the lowest rates, while depreciating assets attract a more cautious advance.
How loan-to-value shapes your offer
Loan-to-value, or LTV, is the loan size as a percentage of the asset’s worth. A lender might advance 70% against commercial property but far less against equipment.
A lower LTV means more of a buffer for the lender, so it usually wins a lower rate. Offering more security, or borrowing a little less, is a practical way to improve a secured deal.
The personal guarantee in each structure
A personal guarantee can sit on both types of loan, but it does different work. On an unsecured loan it is often the only recourse the lender has. On a secured loan it usually backs up the collateral.
Either way, a guarantee makes a director personally liable if the company cannot pay. Understand exactly what you are signing, and consider capping the guarantee where a lender will agree to it.
Sector scenarios: which structure fits
The better choice often follows the type of business.
- Property-rich firms can borrow large sums cheaply on a secured basis.
- Service businesses with few assets usually rely on unsecured loans.
- Manufacturers can secure against machinery to fund expansion.
- Fast-moving retailers may prefer speed, making unsecured the natural fit.
There is no universally right answer — only the structure that matches your assets, speed and risk appetite.
Preparing for a secured loan valuation
A secured loan hinges on the valuation, so it pays to prepare. Keep maintenance records for equipment, and make sure property paperwork and any leases are in order.
A well-documented, well-kept asset values higher and moves faster through the process. Disorganised paperwork is one of the most common reasons a secured application drags on.
Exit and early repayment compared
The two structures behave differently when you want to clear the debt early. Unsecured loans sometimes allow penalty-free settlement, while secured loans more often carry early-repayment charges because the lender priced for the full term.
Always check the exit terms before you sign. If you expect to repay early — say from a property sale — that clause can matter more than a small difference in the headline rate.
Tax treatment of loan interest
Whether secured or unsecured, interest on borrowing for business purposes is generally an allowable expense that reduces taxable profit. The capital you repay is not deductible, only the interest and most associated fees.
The structure of the loan does not change this principle, though larger secured facilities may involve arrangement fees that are also typically deductible. Confirm the detail with your accountant for your specific situation.
What lenders check beyond the asset
Even on a secured loan, the collateral is not the whole story. Lenders still review your turnover, cash flow and credit, because they would rather be repaid than have to sell an asset.
A strong business with good security gets the best terms of all. Treat the asset as one part of the picture, not a substitute for healthy trading.
How to switch from one structure to the other
Businesses often move between structures as they grow. A firm that started with fast unsecured loans may refinance onto a cheaper secured facility once it owns property or equipment.
Plan the switch around early-repayment terms and any new arrangement fees. The move only makes sense if the total cost falls, so compare the full repayable amount, not just the rate.
Insurance and secured borrowing
When you pledge an asset, protecting it becomes part of the deal. Lenders often expect adequate insurance on secured property or equipment so their security is not lost to fire, theft or damage.
Factor any required cover into the true cost of the loan. It is usually modest, but it is a genuine condition of many secured facilities and worth confirming up front.
Case study: choosing between secured and unsecured
Take a manufacturer needing £150,000 for a new machine. They own the machine outright once bought and have a clean balance sheet. A secured loan against the equipment offers a rate near 8% over five years.
An unsecured loan for the same sum is available faster but at around 16%, and not all lenders will go that high without security. Over five years, the secured route saves a substantial amount in interest.
Because the manufacturer is comfortable pledging the asset it is buying, secured wins clearly here. A service business with no asset to offer, needing money this week, would just as clearly choose unsecured.
Expert tips for choosing the right structure
Cut through the decision with these pointers.
- Let the amount guide you: very large sums usually need security.
- Let the timeline guide you: if you need funds in days, lean unsecured.
- Only pledge an asset you could afford to lose in a worst case.
- Always compare the total repayable, not just the monthly cost.
- Ask a broker whether a part-secured deal fits you better.
The best structure is simply the one that matches your assets, your speed and your appetite for risk.
How economic conditions affect each type
The wider economy shapes both structures. When the Bank of England base rate is high, unsecured borrowing tends to feel the squeeze first, because it is priced more on risk.
Secured lending often holds steadier, since the collateral cushions the lender. In uncertain times, a fixed-rate secured loan can offer welcome predictability, while in calmer conditions the speed of unsecured borrowing may matter more.
Combining secured and unsecured borrowing
Many growing businesses run both at once. A secured loan funds a major asset cheaply, while a smaller unsecured facility covers fast-moving working-capital needs.
The key is to keep total repayments comfortably within your cash flow. Used together thoughtfully, the two structures complement each other, giving you both low-cost capital and flexibility.
Questions lenders ask about your assets
If you offer security, expect detailed questions about the asset.
- What is it worth, and how recently was it valued?
- Do you own it outright, or is there existing finance on it?
- How easily could it be sold if needed?
- Is it adequately insured?
Having clear answers and paperwork ready speeds the process and strengthens your position.
Reviewing your borrowing every year
Whichever structure you choose, revisit it annually. As your accounts strengthen, a deal that once looked competitive may now be beatable, and refinancing can cut your costs.
An annual review also keeps your finance aligned with your plans. A business about to invest heavily has different needs from one focused on paying down debt, and your borrowing should reflect that.
A quick decision framework
If you need to decide quickly, work through three questions in order. First, how much do you need — large sums usually point to secured. Second, how fast — days point to unsecured. Third, can you carry the risk to an asset?
Your answers usually make the better structure obvious without further analysis.
How brokers compare both types
A whole-of-market broker can request both secured and unsecured offers at once, then line them up on rate, speed and total cost. That saves you approaching lenders one by one.
It also surfaces part-secured options you might not find alone. Seeing both types together makes the trade-off concrete.
Recap: choosing your structure
- Secured: lower rate, larger sums, asset at risk.
- Unsecured: faster, no collateral, higher cost.
- Compare total repayable, not just the monthly figure.
- Only pledge an asset you could afford to lose.
Match the structure to your amount, timeline and appetite for risk.
Your next step
Whether secured or unsecured suits you better, the way to know your real terms is to compare offers side by side. A whole-of-market enquiry returns both types where you qualify, so you can weigh rate, speed and risk in one place.

Frequently Asked Questions
Secured loans are usually cheaper because the asset reduces the lender’s risk. Unsecured loans cost more but need no collateral and are faster to arrange.
Secured loans reach much higher, often into the millions, because they are backed by an asset. Unsecured loans typically cap around £500,000.
Often yes. A personal guarantee makes a director liable if the business cannot repay, but it does not charge the loan against a specific named asset.
Unsecured loans are faster because there is no asset to value. Decisions can arrive within 24 hours and funds within one to two working days.
Choose secured for large investments and the lowest rate, and unsecured for speed, smaller sums or when you would rather not risk an asset. Compare total cost, not just the rate.
Secured loans are usually cheaper because the collateral lowers the lender’s risk. Unsecured loans cost more but avoid putting an asset on the line, which many owners prefer.
Some lenders offer this for established businesses with strong accounts, but it is less common. Most unsecured lending to small companies asks at least one director for a personal guarantee.
The lender can ultimately take and sell the pledged asset to recover the debt. Most will work with you first, but the risk to the collateral is the core trade-off of secured borrowing.
Unsecured loans are much faster, often funded within one to two working days. Secured loans take longer because the lender must value the asset and register a charge.
Sometimes, but it puts your home at risk if the business cannot repay, so take advice first. Many owners prefer to secure against business assets or choose an unsecured loan to keep the family home separate.
It depends on the asset’s value and the lender’s loan-to-value limit. Commercial property can support large advances, often up to around 70% of value, while depreciating assets support less.
No. A personal guarantee is a promise to repay personally, while secured borrowing pledges a specific asset as collateral. A loan can involve one, both or neither, so check exactly what you are agreeing to.
Yes, if it owns a suitable asset or a director offers one. Security can offset a short trading history, though it puts that asset at risk if the new business cannot repay.
For large sums, secured lending is usually better because the collateral supports a bigger advance at a lower rate. Unsecured loans suit smaller, faster borrowing where you would rather not pledge an asset.
Yes, as long as the combined repayments remain affordable. Many businesses use a secured loan for a major asset and a smaller unsecured facility for working capital, provided cash flow comfortably covers both.
Yes. Many businesses refinance onto a cheaper secured loan once they own a suitable asset. Check for early-repayment charges on the original loan and make sure the total cost genuinely falls.
Secured vs unsecured business loans — side by side
| Feature | Secured | Unsecured |
|---|---|---|
| Security needed | Property or business assets | None |
| Typical amount | £25k – £2m+ | £5k – £500k |
| Typical rate | Lower (6–12% APR) | Higher (8–25% APR) |
| Speed | Slower (valuation) | Fast (24–48 hrs) |
| Risk to you | Asset can be repossessed | No asset at risk (PG may apply) |
| Best for | Larger, longer-term funding | Fast, flexible, smaller sums |
In short: choose secured for larger sums and the keenest rates if you have assets to pledge and time to wait; choose unsecured for speed and to keep your assets clear, accepting a higher rate. Many businesses compare both before deciding.
