Unsecured vs Secured Business Loans, Explained
A secured business loan is backed by an asset the lender can take if the loan is not repaid. An unsecured loan is not, so it is usually faster to arrange and more expensive for the same borrower.
There is a catch worth knowing before anything else. Most online business lending to limited companies is unsecured but comes with a personal guarantee, so the director is still personally on the hook. This guide explains what security actually is, why it changes the price and the speed, and what is worth checking before signing either kind of agreement.
What security actually means
Security means the lender takes a legal charge over something you or the company owns. A charge is a registered claim on the asset. If the loan is not repaid, the lender can take the asset and sell it to get its money back. That is the whole idea in one line: the lender has something to fall back on that does not depend on your cash flow or your goodwill.
Three types of security come up again and again:
- Property. A charge over a commercial unit, a buy-to-let, or sometimes the director's own home. The lender registers its claim, much like a mortgage.
- A debenture. A charge over the company's assets as a whole, usually including a floating charge that covers things which change day to day, such as stock, equipment and money owed to the company.
- A specific asset. In asset finance, the machine or vehicle being financed is itself the security. Stop paying and the lender takes it back.
For a limited company, charges are registered at Companies House, so they are public. Anyone who looks can see what the company has pledged.
A personal guarantee is not security
A personal guarantee is not a charge over an asset. It is a promise. You agree, personally, to repay the company's debt if the company cannot. Nothing is pledged up front, and no charge is registered. But if the company defaults, the lender can sue you personally, and a court judgment can reach your personal money and assets.
This matters because most online business lending to limited companies is unsecured but comes with a personal guarantee. The loan is unsecured from the company's point of view, while the director still carries the risk. In other words, the limited company's protection has a hole in it, and the guarantee is the hole. Our guide to personal guarantees goes through exactly what signing one means.
Watch out for the double-up too. A secured loan can also carry a personal guarantee on top, so the asset and you are both on the line at once.
Why secured is usually cheaper, and slower
Secured lending usually costs less for the same borrower. The lender's risk is lower because there is an asset to fall back on, and lower risk generally shows up as a lower rate.
The price of that price is time. Before a secured loan completes, the lender typically wants:
- a valuation of the asset, which someone has to carry out and someone has to pay for
- legal work to draft the charge and check the title is clean
- registration of the charge, at Companies House for company assets or with the Land Registry for property
Where a family home is involved, lenders often want the owner to take independent legal advice as well, which adds another step. None of this is padding. It is how the lender makes sure the security is worth what it thinks it is worth. But it turns days into weeks.
Unsecured flips the trade. Decisions often ride on bank statements and trading data rather than valuations, so the money can move much faster. The lender carries more risk and prices for it. Faster and dearer, or slower and cheaper. That is the core exchange.
The same £50,000, two ways
Same company, same £50,000. Here is what changes depending on which route the money takes.
| £50,000 unsecured | £50,000 secured | |
|---|---|---|
| Speed | Often days from application to money, because the decision leans on trading data | Typically weeks, because the asset needs valuing and the charge needs drafting and registering |
| Paperwork | Bank statements, filed accounts, ID checks | All of that, plus a valuation, legal documents and charge registration |
| Cost | Usually a higher rate for the same borrower | Usually a lower rate, but with valuation and legal fees on top |
| If it all goes wrong | No specific asset to seize, but if a personal guarantee was signed the lender can pursue the director personally | The lender can take and sell the charged asset. A personal guarantee may sit on top as well |
| Typical term | Often shorter. At Capify, for example, unsecured terms run 3 to 12 months | Often longer. Capify's secured products run up to about two years |
On a short loan the maths gets interesting. Secured brings a lower rate but adds fixed costs (valuation, legal work) that do not shrink just because the term is short. Over a few months those fees can eat a chunk of the rate saving. Over a longer term the cheaper rate has more time to pay for the extra set-up cost.
How real lenders split the difference
Some lenders offer both routes side by side. Fleximize offers unsecured and secured options on loans of £10,000 to £1,000,000, so the same lender can look at a borrower both ways.
Capify splits by term. At the time of checking, its unsecured loans run 3 to 12 months, while its secured products run up to about two years. That fits the general mechanics: lenders are more comfortable lending for longer when there is an asset behind the loan.
Start Up Loans is different again. It is a personal loan used for business, so the debt rides on you rather than the company from day one. There is no charge over business assets, because the company was never the borrower. The set-up is simple, but the personal commitment is real, not smaller.
Questions worth asking before signing anything
Whichever route is on the table, these questions surface the things that hurt later.
- What exactly is the security? Worth getting the asset named in writing. A debenture over the company catches far more than one machine.
- Is there a personal guarantee as well? Secured loans can carry one on top. If so, the worst-case personal liability is a number worth knowing before signing, not after.
- Is the charge fixed or floating, and what does it cover? A floating charge can sweep up stock, equipment and money owed to the company.
- What counts as default? Missing a payment is the obvious trigger. Some agreements list other events too, and the list is worth reading in full.
- What happens to the charge once the loan is repaid? The charge should be released and the release recorded. Old unreleased charges can slow down the next loan or a sale of the business.
- What is the total cost in pounds? Rate, fees, valuation and legal costs added together over the full term. One number beats four percentages.
Common questions
Is an unsecured business loan really unsecured?
From the company's side, yes. No asset is pledged and no charge is registered. But most online business lending to limited companies comes with a personal guarantee, which means the director agrees to repay if the company cannot. The company's assets are free of a charge. The director's finances are not out of the picture.
Which is cheaper, secured or unsecured?
Secured usually carries a lower rate for the same borrower, because the lender has an asset to fall back on. But secured also adds valuation and legal costs and takes longer to arrange. On short terms, those fixed costs can eat some of the rate saving, so the cheaper headline rate does not always mean a cheaper loan overall.
Can a lender take my house over a business loan?
Only by one of two routes. If the home is the named security, the lender has a direct charge over it. If a personal guarantee was signed and the company cannot pay, the lender can sue the guarantor, and a court judgment can put personal assets at risk. Without a charge or a guarantee, a lender to a limited company generally has no claim on the director's home.
Do Start Up Loans involve security?
No charge over business assets is involved, because a Start Up Loan is a personal loan used for business. The debt sits with the borrower personally from the start. That makes it simple, but the personal commitment is bigger than the word unsecured suggests, not smaller.
What is a debenture?
A document that gives a lender a charge over a company's assets, usually including a floating charge covering things that change day to day, such as stock, equipment and money owed to the company. For a limited company it is registered at Companies House, so it is publicly visible.
