Personal guarantees on UK business loans: what directors are really signing
Rook Bristol Editorial · Updated · 8 min read
The short answer
A personal guarantee is a legally binding promise by a director or owner to repay a business debt from their own money if the business cannot. UK lenders often ask for one on unsecured business loans. Before signing, check whether it is capped, whether it is joint and several, what triggers it and whether it covers future borrowing, and take independent legal advice.
Running a limited company is meant to keep your personal finances apart from the business. A personal guarantee quietly moves one debt back across that line. It is one of the most common documents in UK business lending, and one of the least read, so it is worth understanding properly before your name goes on it.
Key takeaways: a personal guarantee makes you personally liable for a business debt if the business cannot pay; lenders ask for them mainly on unsecured lending because no asset secures the loan; the most important terms are the cap, joint and several liability, the trigger and whether it covers future debts; always take independent legal advice before signing.
What is a personal guarantee on a business loan?
A personal guarantee is a separate contract in which you, as an individual, promise the lender that you will pay what the business owes if the business does not.
A limited company or LLP is its own legal person. Its debts normally belong to the company, not to the directors or shareholders. This is what people mean by limited liability. A personal guarantee is an exception you agree to for one lender, and sometimes for one agreement only.
The person giving the promise is called the guarantor. The business is the borrower. If the borrower defaults, meaning it fails to keep to the terms of the loan, the lender can make a demand on the guarantor for some or all of what is outstanding.
Sole traders and most ordinary partnerships are in a different position. There is no separate legal person, so the owners are usually already personally responsible for business debts. A guarantee matters most to directors of limited companies and members of LLPs.
Why do lenders ask for a personal guarantee?
Lenders ask for a personal guarantee because, on unsecured lending, there is no property or equipment to recover if the business fails, so the guarantee gives them a second route to repayment.
There are two practical reasons behind this. The first is recovery. If a company becomes insolvent, unsecured creditors often recover only a small part of what they are owed. A guarantee gives the lender a claim against someone who may still have assets or income.
The second is commitment. A director who has personally backed a loan has a strong reason to keep the business on track and to talk to the lender early if trouble appears. Lenders value that alignment, especially with younger businesses that have a short trading record.
This is why guarantees are more common on unsecured products such as business loans and revolving credit. With asset finance, the equipment itself provides much of the security, although some lenders still ask for a guarantee alongside it.
What is the difference between a limited and an unlimited guarantee?
A limited, or capped, guarantee sets a maximum amount you could ever be asked to pay, while an unlimited guarantee can cover the whole debt plus interest, charges and the lender's recovery costs.
The cap is the single most important number in the document. It is often expressed as a fixed sum, such as £50,000, or as a percentage of the facility. Some guarantees add costs and interest on top of the cap, so read the wording closely rather than relying on the headline figure.
| Type | What you could owe | What to watch for |
|---|---|---|
| Limited (capped) | Up to a stated maximum | Whether interest and legal costs sit inside or on top of the cap |
| Unlimited | The full outstanding debt, plus costs | Your maximum exposure grows with the facility |
| Specific | Only the named agreement | Whether a top-up or renewal counts as a new agreement |
| All monies | Any debt the business owes that lender, now or later | New borrowing can be covered without a fresh signature |
| Joint and several | Potentially the full amount, even with co-guarantors | The lender can pursue whichever guarantor it chooses |
Joint and several liability deserves its own explanation. If three directors each sign, you might assume each is responsible for a third. Under a joint and several guarantee, the lender can ask any one of you for the whole amount. You may then have a claim against your co-guarantors, but that is your problem to pursue, not the lender's.
What happens if a personal guarantee is called?
If a guarantee is called, the lender sends the guarantor a formal written demand for payment, and if that is not met it can take legal action to recover the money from the guarantor personally.
A guarantee is usually triggered by an event of default. That might be missed repayments, the company entering administration or liquidation, or another breach set out in the loan agreement. The exact triggers are listed in the documents, and they are not always limited to insolvency.
In practice, many lenders will try to agree a repayment plan with the guarantor before going to court. If that fails, the lender may seek a County Court Judgment, known as a CCJ, which is a court order to pay. An unpaid judgment can lead to further enforcement and, in serious cases, a bankruptcy petition. Where a guarantee is secured on your home, the lender may have rights over that property too.
GOV.UK has plain-English guidance on what happens when a company is wound up and on personal insolvency, and the Insolvency Service publishes information for directors. If you are worried about a guarantee being called, speak to a solicitor or a licensed insolvency practitioner early. The earlier you act, the more options usually remain.
- The business misses a payment or another trigger event occurs.
- The lender contacts the business to try to put things right.
- If the default continues, the lender makes a formal demand on the guarantor.
- The guarantor and lender discuss payment in full or an affordable plan.
- If no agreement is reached, the lender may begin court proceedings.
How much could I be liable for? A worked example
You could be liable for up to the cap in a limited guarantee, or for the full outstanding balance plus costs in an unlimited one, depending on how much has been repaid when the default happens.
The figures below are illustrative only. They show how the same default can play out very differently depending on the guarantee wording.
| Scenario (illustrative) | Outstanding balance | Guarantee terms | Maximum demand on one director |
|---|---|---|---|
| A | £70,000 | Unlimited, joint and several | £70,000 plus interest and costs |
| B | £70,000 | Capped at £40,000 each, several only | £40,000 |
| C | £70,000 | Capped at £40,000, joint and several, costs on top | £40,000 plus recovery costs |
| D | £25,000 | Capped at £40,000 each | £25,000, as the debt is below the cap |
In scenario A, a director who has personal savings could be asked for the whole £70,000, even though a co-director signed too. In scenario B, the most either director could face is £40,000. Scenario D shows why caps matter less as a loan is paid down: the guarantee can never exceed what is actually owed.

Are personal guarantees regulated by the FCA?
Most business lending to limited companies, and the guarantees attached to it, falls outside the Financial Conduct Authority's consumer credit rules, although some smaller loans to sole traders and partnerships can be regulated.
The FCA regulates certain credit agreements under the Consumer Credit Act, including some lending to sole traders and small partnerships below a set threshold. Where a loan is regulated, related guarantees can carry extra protections, such as rules about the information you must receive. For company lending, the protection comes mainly from contract law and the need for clear, fair documents.
Because the rules depend on who is borrowing and how much, check the current position on the FCA website or ask your adviser. Do not assume a protection applies unless someone qualified has confirmed it for your agreement.
What should I check before signing a personal guarantee?
Before signing, confirm the cap, whether liability is joint and several, what triggers the guarantee, what debts it covers, and how and when it can be released.
- Is there a cap, and does it include or exclude interest and legal costs?
- Is liability joint and several, or does each guarantor carry only their own share?
- What exactly are the trigger events, and is there a period to put things right first?
- Does it cover this agreement only, or all money the business owes the lender now and in future?
- Is it secured on any personal asset, such as your home?
- Can it be released or reduced once part of the loan is repaid, or if you leave the business?
- Does it survive after you resign as a director? Many do unless formally released.
- Has your spouse or partner been asked to sign anything, and have they had separate advice?
Our guide on how to read a business finance offer covers the other terms that sit alongside a guarantee, from fees to early settlement.
Take independent legal advice before you sign any personal guarantee. A solicitor can explain what the wording means for your circumstances. This article is general information, not advice.
Can I negotiate or avoid a personal guarantee?
Sometimes you can negotiate the terms, such as a lower cap or a release date, though whether a lender will remove a guarantee altogether depends on the lender, the product and the strength of the business.
Things that can help your case include a longer trading history, steady turnover, healthy bank statements and a clean credit file. Lenders read your statements closely, so it is worth knowing what lenders see in your bank statements before you apply.
- Ask whether a capped guarantee is available instead of an unlimited one.
- Ask for the cap to reduce as the loan balance falls.
- Ask whether it can be limited to this facility only, rather than all monies.
- Ask for several liability, so each guarantor is responsible only for a set share.
- Consider borrowing a smaller amount if that brings the guarantee to a level you are comfortable with.
Some insurers offer personal guarantee insurance, which may cover part of a claim. Policies vary widely, so read the exclusions and waiting periods with care. It is also worth building a strong business credit profile over time, which we cover in how to build business credit in the UK.
