At some point, most businesses need extra funding. It could be to smooth a cash flow gap, invest in new equipment, or take advantage of a growth opportunity. One of the first choices you’ll face is between a secured loan and an unsecured loan.

Both options provide access to finance, but they work in very different ways. The speed, risk, and flexibility can all vary depending on which route you take. Understanding the difference between secured and unsecured loans makes it easier to match the right type of funding to your goals and timeline.

In this guide, we’ll cover:

  • What a secured loan is, with practical examples;
  • What an unsecured loan is, and how it compares;
  • The key differences between the two;
  • How to decide which option fits your business best.

What is a Secured Loan?

A secured loan is funding that’s backed by something your business owns. This security, often called collateral, could be property, vehicles, or equipment.

By tying the loan to an asset, the lender takes on less risk. That usually means you can borrow larger amounts and access lower interest rates.

For many SMEs, secured loans make bigger projects possible. This might include expanding premises, buying new machinery, or spreading the cost of long-term investments.

The trade-off is that the process can take longer, as the asset has to be valued, and you’re putting something on the line if repayments are missed.

 

First charge and second charge lending

When a lender registers a charge against your property, they are establishing their position in the repayment queue. A first charge lender ranks ahead of all others and is repaid first from any sale proceeds. A second charge sits behind an existing mortgage and is only repaid once the first charge is cleared.

Second charge lending is available but from a narrower lender panel and at a higher rate, to reflect the additional risk of sitting further back in the queue. If you already have a mortgage on your commercial property or your home and want to raise further finance against it, a second charge is the route. It does not require you to remortgage or break an existing deal.

For most business secured lending, lenders advance up to 70% of the property value on a first charge basis. Second charge lenders may advance less, depending on the equity available after the first charge is accounted for.

 

What is an Unsecured Loan?

An unsecured loan gives your business funding without needing to put assets on the line. Instead, the lender looks at your financial profile – things like turnover, trading history, and credit score – to decide how much to offer and on what terms.

The biggest advantage is speed. With no collateral to assess, unsecured loans are often approved faster than secured loans. They’re flexible too, which makes them a good fit for managing cash flow, covering short-term costs, or funding new projects on a tight timeline.

The trade-off is that lenders carry more risk, so the amounts available are usually smaller and the interest rates can be higher.

 

Personal guarantees on unsecured loans

Most unsecured business lenders require a personal guarantee from one or more directors before they will lend. This is a legal commitment that if the business fails to repay, the director becomes personally liable for the debt.

A personal guarantee is not the same as providing security. No charge is registered against a specific asset and it does not appear on a property search. But it is a personal obligation that follows you, and the consequences of default can include county court judgments against the director personally. It should be read carefully and understood before signing.

Some lenders offer limited personal guarantees, capped at a percentage of the outstanding balance. Others require a full guarantee. Whether a personal guarantee is required, and on what terms, is one of the things a broker will clarify before presenting options.

 

Secured vs Unsecured Business Loans: Key Differences

The main difference between secured and unsecured loans is how the funding is backed.

A secured loan is tied to an asset, such as property or equipment, which lowers the lender’s risk. This lets you borrow larger amounts at better rates, though the process takes longer because the asset needs to be valued.

An unsecured loan doesn’t require collateral. Instead, approval depends on your business’s financial profile – turnover, credit history, and trading record. These loans are usually quicker to arrange and more flexible, but you’ll often be limited to smaller amounts with higher interest rates.

A secured loan is the stronger option for businesses planning bigger, long-term investments and comfortable using assets as security. An unsecured loan can be the smarter choice when speed matters most, such as covering everyday costs or bridging a short-term gap.

 

What does the rate difference actually cost?

The rate gap between secured and unsecured lending looks modest in percentage terms, but adds up significantly over a full term. On a £100,000 loan over five years:

Secured loan Unsecured loan
Loan amount £100,000 £100,000
Term 60 months 60 months
Indicative rate ~8% per annum ~18% per annum
Monthly repayment ~£2,030 ~£2,540
Total repayable ~£121,800 ~£152,400
Additional interest cost n/a ~£30,600 more

Figures are indicative. Actual rates depend on your credit profile, trading history, lender, and whether security is available.

That £30,600 difference is the cost of not having security behind the application. For some businesses the trade-off is straightforward: if you need funds in 48 hours and the amount is under £100,000, unsecured is the practical choice regardless of rate. If you have property available and can wait for the valuation process, the secured route saves a significant amount over the term.

 

Which Loan is Right for Me?

Both secured and unsecured loans play an important role in business finance. The right choice depends on how much you need, how quickly you need it, and whether you’re comfortable using assets as security.

If you’re planning a larger investment, such as expanding your premises or buying new machinery, a secured loan usually offers the best fit. You’ll be able to borrow more and benefit from lower rates, as long as you’re comfortable securing the loan against property or equipment.

If your priority is fast access to cash, or you only need a smaller amount to cover day-to-day costs, an unsecured loan is often more practical. The application process is quicker, and you don’t risk putting assets on the line, though you may face higher rates.

 

Choose a secured loan when:

✓ You need more than £250,000

✓ You want a longer term or a lower monthly payment

✓ You have commercial property, residential property, or significant assets to leverage

✓ You can wait 4 to 12 weeks for the valuation and legal process

✓ Minimising total interest cost over a long term is the priority

 

Choose an unsecured loan when:

✓ You need funds quickly, within 24 to 72 hours

✓ The amount is under £250,000

✓ You do not have assets available to secure against

✓ It is a short-term working capital need rather than a long-term investment

✓ You would rather not place a charge on property

The choice between secured and unsecured is not always obvious from the outside. A business that assumes it cannot secure lending because it rents its premises may have equipment or vehicle assets that qualify. A business that defaults to unsecured because it seems simpler may be paying significantly more than it needs to. A broker with access to both markets can tell you within a conversation which route makes more sense for your situation, before any credit searches are run.

Secured Vs Unsecured Business Loan FAQs

  • What can I use as security for a secured business loan?

    Commercial property is the most common form of security, but residential property owned by a director can also be used. Beyond property, lenders will consider plant and machinery, vehicles, stock, and debtors depending on the product. The asset needs to have a demonstrable market value and be something the lender could realistically sell if the loan defaulted. Highly specialised or bespoke assets are harder to use as security because the resale market is limited.

  • Do I need a personal guarantee for an unsecured loan?

    In most cases, yes. Personal guarantees are standard practice for unsecured business lending in the UK. The lender has no asset to fall back on, so the director's personal commitment is how they manage that risk. It is worth understanding exactly what you are signing: whether the guarantee is unlimited or capped, whether it covers just the outstanding balance or includes interest and costs, and what triggers it.

  • How long does a secured business loan take to arrange?

    Typically 4 to 12 weeks, depending on the complexity of the security and how quickly valuations and legal work can be completed. A straightforward commercial mortgage on a clean freehold property sits at the lower end. A second charge on a property with an existing mortgage, or a deal involving multiple assets, sits at the higher end. Unsecured loans can complete in 24 to 72 hours for straightforward applications.

  • Is a secured loan always cheaper than an unsecured loan?

    The rate is lower, but the total cost depends on the term. A secured loan at 8% over 10 years carries more total interest than an unsecured loan at 15% over 2 years, simply because of the length. Rate and term together determine what you actually pay. The secured route is generally better value for larger amounts and longer terms. For short-term needs, unsecured can be cheaper overall even at a higher headline rate.

  • What is the maximum I can borrow on a secured business loan?

    There is no fixed ceiling. The limit is determined by the value of the security you can offer and the lender's LTV appetite. Most lenders advance up to 70% of commercial property value on a first charge basis. For residential property, up to 75% is common. On larger deals with strong trading history, some lenders will go higher. In practice, £5 million and above is achievable for the right security and the right business.
