An unsecured business loan gives a UK limited company a lump sum of capital without pledging any specific asset as security. No charge over your premises, no debenture over your debtors, no all-assets pledge. For a director who wants funding fast and does not want to tie up the company balance sheet, that is the appeal. But nothing in lending is free of risk to the lender, and where security is absent the risk has to sit somewhere. In unsecured business lending, it sits on a director's personal guarantee. That is the honest hook of this whole product, and the thing most comparison articles gloss over.
This guide is written for limited-company directors and finance leads. It covers what unsecured really means, how lenders price the risk without collateral, the personal guarantee reality in full, what your company is likely to be offered, and when the higher rate of an unsecured loan is worth paying versus a secured alternative. It is a finance guide, not a tax guide; where tax is relevant we point you one hop to the right resource rather than repeat it.
What "unsecured" actually means
A secured business loan is backed by a legal charge over an asset: commercial property, plant and machinery, or an all-assets debenture registered at Companies House. If the company defaults, the lender can enforce that charge and recover its money from the asset. An unsecured loan has no such charge. The lender advances money against the strength of the company's trading and its confidence that future cash flow will service the debt.
That single difference drives everything else about the product: the rate, the amount, the term, the speed, and the guarantee requirement. Because the lender cannot fall back on an asset, it prices in more risk, lends smaller sums, over shorter terms, and almost always asks a director to stand behind the debt personally. Understanding that chain of consequences is the key to using unsecured lending well.
Unsecured business loans typically run from £25,000 upwards. Below roughly £25,000, and for sole traders or individuals, borrowing falls into consumer-credit territory that is regulated and outside what we introduce. Our introductions are for company facilities, so the fence is deliberate: this page is about companies borrowing £25,000 or more for business purposes.
How lenders price risk without security
When there is no asset to seize, a lender has only two things to lean on: the quality of the company's trading and the guarantee of the people behind it. So an unsecured underwriter looks hardest at:
- Turnover and its trend. Rising, stable turnover reassures; a recent dip raises the rate or shrinks the offer. Many lenders size the loan at up to one month of turnover.
- Filed accounts and profitability. Two or more years of clean, profitable accounts is the sweet spot. Loss-making or very young companies pay more or are declined.
- Bank conduct. Lenders often read 6 to 12 months of business bank statements. Returned direct debits, an always-full overdraft, or existing short-term loans all count against you.
- Company credit file. County court judgments, late-payment markers and existing charges at Companies House are all visible and all matter.
- Director creditworthiness. Because the guarantee underpins the deal, a director's personal credit file is assessed almost as closely as the company's.
- Sector and debt stacking. Some sectors carry higher default rates and price accordingly. Several stacked short-term loans (loan stacking) is a strong negative signal.
The output of all this is a risk-based rate. There is no single unsecured business loan rate. A strong, established company can borrow unsecured at a rate not far above a secured facility; a weaker or younger one pays a substantial premium or is asked for security instead. This is exactly why a broker panel, rather than a single bank, tends to produce a better outcome: the same company profile is priced very differently across lenders.
Personal guarantees explained
This is the section to read twice. A personal guarantee (PG) is a legal promise by a director (or several directors) to repay the company's loan personally if the company cannot. It converts limited liability, the whole point of trading through a company, into personal exposure for this specific debt. For unsecured lending it is close to universal, because the guarantee is the lender's substitute for the security it did not take.
Key things every director should understand before signing:
- Extent. A guarantee is often for the full loan balance plus interest and costs. Some lenders cap it at a percentage; that cap is worth negotiating.
- Joint and several. Where two directors guarantee, each can usually be pursued for the whole amount, not just their share. The lender chooses who to chase.
- Assets at risk. A called guarantee can reach personal savings and, in some cases, the guarantor's home. This is not the company's risk any more; it is yours.
- Guarantee insurance. Personal guarantee insurance exists and covers a proportion of the exposure. It is a cost, but for a large PG it can be sensible.
- Independent advice. Some lenders require you to take independent legal advice before signing. Even where they do not, it is wise for a substantial guarantee.
The PG is a company-director instrument, not a consumer product. It is given by the people running a limited company in support of that company's business borrowing. That framing is what keeps the introduction unregulated, and it is why sole traders and personal borrowers are routed elsewhere. If you are not willing to give a personal guarantee, an unsecured loan is probably not your route, and a secured facility (where the asset carries the risk) may suit you better.
Eligibility: what a company needs to qualify
There is no universal checklist, but most unsecured lenders look for a recognisable version of the following from a limited company:
- Registered UK limited company (or LLP) trading for business purposes.
- Usually 12 to 24 months of trading with filed accounts. Some lenders accept 6 months with stronger guarantees.
- Turnover that comfortably supports the repayment. Loans are frequently sized around one month of revenue.
- Reasonable company and director credit profiles, with CCJs and defaults explained or cleared.
- A director willing to give a personal guarantee.
- Business bank statements and management information available on request.
Newer companies are not automatically excluded, but they face a higher bar. A company with under a year of trading typically needs a director with strong personal credit, a robust guarantee, or a government-backed route such as the Growth Guarantee Scheme via an accredited lender. Genuine startups with no trading history are usually better served by asset finance on a specific purchase, or should note that the government Start Up Loan is a personal loan to the individual rather than a company facility. We introduce company facilities, not that personal scheme.
Typical amounts, terms and rates
Unsecured business loans generally sit in these ranges, though every offer is individually priced:
| Feature | Typical unsecured business loan |
|---|---|
| Amount | £25,000 to around £500,000 (turnover-linked) |
| Term | 1 to 5 years, occasionally 6 |
| Speed to funds | 24 to 72 hours to decision, funds within days |
| Security | None over assets; personal guarantee almost always required |
| Repayment | Fixed monthly (capital and interest), some daily-rate short-term products |
| Best for | Working capital, hiring, marketing, tax bills, contract funding, speed |
The headline rate is risk-based and varies widely. Rather than quote a single figure that will be wrong for most readers, the useful point is the shape: shorter terms and no security mean the monthly payment is higher than an equivalent secured loan, and the total finance cost over the life is higher too. You trade a higher price for speed and for keeping your assets unencumbered. Model the monthly cost of any offer before signing with our business loan calculator.
Worked example: £50,000 unsecured versus £50,000 secured
Consider a trading limited company, three years old, £700,000 turnover, that needs £50,000 for a growth push (hiring and marketing) with nothing specific to secure it against. It compares two routes.
| Unsecured loan | Secured loan (charge over premises) | |
|---|---|---|
| Amount | £50,000 | £50,000 |
| Indicative rate | ~14% representative | ~8% representative |
| Term | 4 years | 7 years |
| Approx. monthly payment | ~£1,365 | ~£779 |
| Approx. total interest | ~£15,500 | ~£15,400 |
| Security | None over assets; full director PG | Legal charge over premises; PG likely too |
| Time to funds | Days | Several weeks (valuation + legal) |
The figures are illustrative, not a quote, but they show the real trade-off. Over similar horizons the total interest can land in a comparable range, yet the unsecured route packs it into a shorter term, so the monthly cost is far higher and the affordability test tighter. The secured route is cheaper per month and stretches longer, but it registers a charge over the premises, takes weeks, and puts the property on the line as well as the guarantee. For a fast £50,000 working-capital need where the company would rather not encumber its premises, the unsecured premium is often a price worth paying. For a large, long-term capital project, security usually wins. The personal guarantee sits on both, which surprises many directors: a secured loan does not remove the PG, it simply adds a charge on top of it.

Unsecured versus secured versus asset finance
Three routes, three different jobs:
- Unsecured loan. Fast, flexible, no asset charge, higher rate, shorter term, personal guarantee. Best for intangible or spread-out spending: hiring, marketing, working capital, tax bills.
- Secured business loan. Cheaper, larger, longer, but needs an asset and a legal charge, and takes weeks. Best for major, long-term investment where you have property or substantial assets to pledge.
- Asset finance. For buying a specific, identifiable asset (vehicle, machine, fit-out), the asset itself secures the deal, so it is usually cheaper than an unsecured loan. Best when the spend is one clear piece of kit rather than general funding.
Many growing companies use a combination: asset finance for equipment, an unsecured loan for the softer costs, and a secured facility for a genuinely large project. If your company is small and simply testing what it can access, start with our small business loans guide, then use the pillar below to map the full menu.
When an unsecured loan is worth the higher rate
An unsecured business loan earns its premium in specific situations:
- Speed matters. A contract to fulfil, a supplier discount to seize, a gap to bridge now. Weeks of valuation and legal work would cost you the opportunity.
- You have no suitable asset to pledge, or you do not want to tie up the one you have. A young or asset-light company often has nothing to secure against anyway.
- The amount is modest relative to turnover. £25,000 to £150,000 for a company with solid revenue is squarely unsecured territory, where the rate premium on a smaller sum is manageable.
- The spend is intangible. Hiring, marketing and working capital produce no asset for a lender to secure, so unsecured is the natural fit.
Conversely, if you are borrowing a large sum over a long horizon and you hold an asset you are willing to charge, the secured route almost always costs less. The discipline is to match the product to the job, not to default to whatever a single bank offers.
How to apply
Preparation is what turns a slow, expensive decision into a fast, competitive one. Before you enquire, have ready:
- Your two most recent sets of filed accounts (or management accounts if the latest are not filed yet).
- 6 to 12 months of business bank statements.
- A clear figure and purpose for the borrowing.
- An honest view of director personal credit, since the guarantee depends on it.
- Any existing finance already in place, so serviceability can be assessed accurately.
Rather than applying to one bank and taking whatever comes back, a commercial-finance broker panel puts your company profile in front of multiple lenders at once, which matters most in unsecured lending precisely because pricing varies so much between them. For the tax side, whether that is the deductibility of loan interest through the loan relationships rules or how the borrowing sits alongside your corporation tax position in 2026/27, that is one hop away: see our guide to corporation tax and marginal relief or ask an accountant. And for the full menu of company debt, from revolving facilities to government-backed schemes, start at the business loans guide pillar.
