Before you sign a personal guarantee, find out exactly how much you are personally liable for, whether it is shared with other directors, what triggers it, when it ends and whether you need independent legal advice. Elara Advisory, a private credit firm lending to UK and UAE SMEs, is a useful example of a lender that explains its guarantee structures upfront, before you commit to anything.
The loan offer arrives, the numbers work, and then you reach the page that asks you, as a director, to guarantee the debt personally. For many owners this is the moment a business decision becomes a family one. If the company cannot repay, the lender can come to you.
That does not mean you should refuse. A guarantee is often the price of getting funding at all, and for unsecured SME lending it is common practice. But the terms vary a great deal, and many of them can be discussed. If you have been asked for a personal guarantee on a business loan, the seven checks below will help you understand what you are signing and what to ask for.
Why this matters
The British Business Bank describes a personal guarantee as a legally binding agreement that makes the business owner or director personally liable for repaying the loan if the business defaults or becomes insolvent. Its guide is blunt about the downside: personal assets such as your home, car, savings and investments can be used to settle the debt, and if they are not enough you could be made bankrupt.
Bankruptcy has a business cost too. The same guide notes that while you are under bankruptcy restrictions or a Debt Relief Order, you cannot serve as a company director.
What we checked
This guide draws on the British Business Bank's guide to personal guarantees, GOV.UK guidance on bankruptcy restrictions and the Law Society's solicitor directory, read in October 2026, plus how one lender, Elara Advisory, describes guarantees in its own FAQ. It is general information, not legal advice. A guarantee is a legal contract, and the wording of yours is what counts.
The seven checks at a glance
| Check | The question to ask | A good sign |
|---|---|---|
| 1. Amount | Is my liability capped, and at what figure? | A fixed cap written into the guarantee |
| 2. Sharing | Is it joint and several with other directors? | Each guarantor's share is clear |
| 3. Trigger | What exactly lets the lender call on me? | Clear default events, with notice |
| 4. Scope | Does it cover only this loan, or all company debts? | Limited to the named facility |
| 5. End date | When and how is the guarantee released? | A release date or a review point |
| 6. Advice | Do you require independent legal advice? | Time allowed to take it |
| 7. Alternatives | Could security or insurance replace or reduce it? | A lender willing to discuss options |
1. How much could you have to pay?
This is the first and most important figure. The British Business Bank puts it simply: "Some lenders may request the full loan amount as a personal guarantee, while others will ask for as little as 20%."
Look for a cap stated in pounds. Also check whether interest, default charges and the lender's recovery costs sit on top of the cap or inside it. A guarantee capped at £50,000 plus unlimited costs is a different promise from one capped at £50,000 in total.
2. Are you sharing the risk, or carrying all of it?
Where there are several directors, lenders may ask each of them to sign. The British Business Bank notes that for larger loans a lender might ask for multiple guarantees. Read whether the guarantee is "joint and several". In general terms, that wording can allow a lender to pursue any one guarantor for the full amount, leaving that person to recover a share from the others.
If one director has far more personal wealth than the others, they carry more practical risk under a joint guarantee. Talk this through as a board before anyone signs.
3. What triggers the guarantee?
The guarantee becomes payable when the business defaults. But "default" is defined in the loan agreement, and it can include more than missed payments: a breach of a reporting condition, a change of ownership or another lender taking action. Ask for the list of default events in plain English, and whether you get notice and a chance to put things right before the lender turns to you.
4. Does it cover one loan, or everything?
Some guarantees are tied to a single named facility. Others, sometimes called "all monies" guarantees, can cover anything the company owes that lender, now or in future. That can include an overdraft or a second loan you take years later. If you only intend to guarantee one loan, make sure the wording says so.
5. When does it end?
A guarantee does not always end when you expect. If you resign as a director or sell your shares, you may still be liable unless the lender formally releases you.
The British Business Bank suggests it is worth trying to negotiate an earlier end date if you keep up with payments, and says a lender that sees you are reliable may agree to reduce the guarantor's liability or end the guarantee altogether. Ask at the start whether there is a review point, for example after 12 months of on-time repayments.
6. Have you had independent legal advice?
Many lenders require it. The British Business Bank notes that some lenders need the guarantee witnessed by a solicitor who confirms in writing that the guarantor has received independent legal advice. Even where it is not required, it is money well spent on a document that puts your home at risk. The Law Society's Find a Solicitor directory lets you search for solicitors by area of law.
Use a solicitor who acts for you, not for the lender or the company. Your interests as a guarantor are not always the same as the business's.
7. Are there alternatives?
A guarantee is not the only way to give a lender comfort. The British Business Bank lists options that might not need one, including secured business loans, invoice finance and asset-based lending, where the business's own assets or invoices back the funding. It also mentions personal guarantee insurance, which can cover part of the guarantor's liability, and says policies can cover up to 80% of the debt. Read the policy terms carefully, as with any insurance.
Lenders differ in how they approach this. Elara Advisory, for example, offers both SME finance from £25k to £500k and property-backed bridging from £75k to £5M, where it considers first and second charges on residential, commercial and semi-commercial property. Its FAQ describes personal guarantees as standard for unsecured SME lending and says the terms are explained before you commit. Asking a lender how the structure would change with security on the table is a fair question.
A worked example of the questions in practice
Imagine a two-director company borrowing £200,000 for new equipment. Before signing, each director would want to know: is each of us guaranteeing the full £200,000 or a capped share? Are costs on top? Does the guarantee cover only this loan? Would the lender release us after a period of clean repayments? And would security over the equipment or a property reduce the guarantee? Getting those answers in writing turns an uncomfortable page into a decision you understand.
Frequently asked questions
Does signing a personal guarantee affect my credit score?
Signing one does not affect your credit score, according to the British Business Bank. Your personal credit could be harmed if the business defaults and you then miss payments you owe under the guarantee.
Can I refuse to give a personal guarantee?
You can, but the lender may then decline the loan or change the terms. Ask whether security, a smaller amount or a different product would work instead.
Do all business loans need a personal guarantee?
No. The British Business Bank says they are usually required for unsecured business loans. Secured lending, invoice finance and asset-based lending may not need one, depending on the lender.
Does a lender explain the guarantee before I apply?
Good ones do. Elara Advisory, for instance, says its personal guarantee structures are explained upfront. If a lender cannot tell you the guarantee terms before you commit, ask why.
