Personal Guarantees on Business Loans — What You Are Actually Signing
Most SME owners sign personal guarantees without fully reading them. They are presented as standard, routine, nothing to worry about. Some of them are. Some of them are not. Here is what you need to understand before you put your name on one.

Before you sign: A personal guarantee is a legal document. If you have any doubt about the terms, get independent legal advice before signing. Many solicitors will review a personal guarantee for a fixed fee — typically £150–£300. That is cheap compared to what you might be signing away.
What is a personal guarantee?
A personal guarantee is a legally binding promise from you — as an individual, not as your company — that if the business fails to repay a loan, you will repay it personally.
Limited companies exist partly to separate your personal finances from your business finances. A personal guarantee pierces that separation. If you sign one and the business defaults, the lender can pursue you directly — regardless of limited liability status.
That means your personal savings, your car, investments, and potentially your home are all on the table. Not necessarily — it depends on the guarantee terms — but potentially.
When do lenders require a personal guarantee?
Whether a personal guarantee is required depends on the type of finance, your business profile, and the lender. As a general rule:
Unsecured business loans
Almost always requiredThe lender has no asset to repossess if you default. A personal guarantee is their only security.
Invoice finance (factoring / discounting)
Usually requiredThe invoices themselves provide some security, but most providers still require at least one director guarantee. Terms are often less onerous than for unsecured loans.
Secured business loans (property-backed)
Sometimes requiredThe loan is secured against a business asset. A personal guarantee may still be required as additional security, but it is more negotiable.
Business debt consolidation
Depends on structureIf consolidating into an unsecured loan, almost certainly required. If consolidating into a secured facility, it varies.
Merchant cash advances
Often requiredMCAs are structured as a purchase of future receivables but typically still require a director guarantee.
What is actually at risk?
This is where people get a surprise. "Personal guarantee" sounds like a minor formality. In practice, it can mean the lender can pursue:
Personal savings and bank accounts
High
Easiest for lenders to identify and pursue.
Your car and other vehicles
Medium
If owned personally, not through the business.
Investments and pensions
Medium
Pensions have some protection — complex area.
Your home
Situation-dependent
Depends on guarantee terms and whether jointly owned.
Your home specifically: If the guarantee is unsecured (no explicit charge over your property), the lender would need to go to court, obtain a judgment, and then apply for a charging order on your home. This takes time and is not automatic. But it is possible. If the guarantee is explicitly secured against your home, the lender can enforce much more directly. Read the guarantee carefully. If your home is mentioned, get legal advice.
Types of personal guarantee — not all are the same
Unlimited personal guarantee
You are personally liable for the full outstanding debt, including interest and legal costs. No cap on what can be recovered from you. Most onerous — read carefully before signing.
Limited personal guarantee
Your liability is capped at a fixed amount (e.g. £50,000 regardless of the loan balance). Better than unlimited — negotiate for this if you can.
Joint and several guarantee (multiple directors)
If multiple directors sign, the lender can pursue any one of you for the full amount — they are not limited to your proportional share. Each director carries the full risk.
Proportional guarantee (multiple directors)
Your liability is proportional to your shareholding (e.g. 50% of the debt if you own 50% of the business). Fairer — ask for this specifically when multiple directors are signing.
Guarantee with indemnity
Broader than a standard guarantee. Includes a promise to cover the lender's losses even if the underlying loan agreement turns out to be unenforceable. More lender-friendly — read the small print.
What can you negotiate?
Personal guarantees are not always take-it-or-leave-it. Especially for established businesses with strong trading history, there is often more room to negotiate than lenders let on. Things worth asking about:
Cap the liability
Ask for a maximum amount — either a fixed sum or a percentage of the loan balance. “I will personally guarantee up to £X, not the full facility.” Some lenders will agree.
Sunset clause
The guarantee expires or reduces after a period of good repayment (e.g. 12 months of on-time payments). Rewards good behaviour and reduces long-term personal exposure.
Exclude your primary residence explicitly
Get it in writing that the guarantee cannot be enforced against your home. Some lenders will agree; others will not.
Proportional rather than joint and several
If multiple directors are signing, push for liability proportional to shareholding rather than joint and several.
Require the lender to exhaust business assets first
Some guarantees allow the lender to come straight to you. Ask for a clause requiring them to recover from business assets first before enforcing the personal guarantee.
How to assess whether to sign
There is no universal answer to whether you should sign a personal guarantee — it depends on your circumstances, the terms of the guarantee, and what you are using the finance for. These questions help frame the decision:
What is the realistic worst-case scenario? How likely is it that the business cannot repay? What happens to you personally if it cannot?
What am I personally exposed for? Is the guarantee unlimited? Is there a cap? Does it cover my home?
Is there a lender who will offer similar terms without a personal guarantee — or with a more limited one?
If I sign and the business later fails, what personal assets am I actually at risk of losing?
Has my solicitor reviewed this guarantee and explained it clearly?
The honest reality: For most SME loans, a personal guarantee is unavoidable. The lender will not offer the finance without one, and you need the finance. The goal then is not to avoid the guarantee but to understand exactly what you are signing, negotiate the best terms you can, and make sure the finance is used for something that materially improves the business's ability to repay.
Personal guarantees and invoice finance
Invoice finance facilities typically require at least one director guarantee, but the nature of the product means the guarantee is usually less exposed than for a term loan.
With invoice finance, the advance is secured against your debtor book — actual invoices raised to creditworthy customers. If the facility is terminated, the provider collects from those customers and repays itself. The personal guarantee is there mainly to cover situations where invoices turn out to be fraudulent, disputed, or simply uncollectable — scenarios that should not arise in normal operation.
That does not mean you should ignore the guarantee on an invoice finance facility — it is still a legal obligation. But the practical risk is generally lower than on an equivalent unsecured loan.
Frequently asked questions
What is a personal guarantee on a business loan?
A personal guarantee is a legally binding promise that if your business cannot repay a loan, you will repay it personally. It moves the risk from the business to you as an individual. If the business defaults, the lender can pursue you for the outstanding balance — potentially including your personal savings, car, and in some cases your home.
Can a lender come after my house if I sign a personal guarantee?
Yes, in theory — but it depends on the terms of the guarantee and the lender. Some guarantees are explicitly secured against property; others are unsecured but can still result in a charging order on your home if the lender goes to court and obtains a judgment. Read the guarantee carefully. If the lender mentions your primary residence, ask for clarification in writing.
Are personal guarantees required for all business loans?
No. Whether a personal guarantee is required depends on the type of loan, the lender, your business credit profile, and what security is available. Unsecured business loans almost always require a PG. Secured loans (backed by business property or assets) sometimes do not. Invoice finance often requires a director guarantee but the terms vary. Established businesses with strong accounts may be able to negotiate guarantees away or reduce them.
Can I negotiate a personal guarantee?
Yes, and it is worth trying. You can negotiate the guarantee amount (a cap on your personal liability), the duration (a sunset clause after a period of good repayment), the scope (excluding your primary residence), and whether the guarantee is joint and several or proportional if multiple directors are signing. Not all lenders will agree to changes — but many will consider them, especially via a broker who knows the lender.
Does invoice finance require a personal guarantee?
Usually yes — most invoice finance providers require at least one director to sign a personal guarantee. The terms are often less onerous than for a term loan because the advance is secured against your invoices (an asset), not unsecured. Some providers offer facilities without a personal guarantee, particularly for established businesses with strong trading history and high-quality debtors.
