A Guide to Personal Guarantees for Business Loans

When applying for business finance, many lenders will ask for a personal guarantee as part of the agreement, particularly for unsecured lending.

For business owners, understanding how personal guarantees work is important before signing any finance agreement. While they can improve access to funding and help secure better terms, they also involve personal financial risk.

In this guide, we explain what a personal guarantee is, why lenders use them, the risks involved, and what business owners should consider before agreeing to one.

Personal Guarantees at a Glance

What Is a Personal Guarantee?

A personal guarantee is a legally binding agreement where a business owner, director or senior individual agrees to become personally responsible for repaying a business debt if the company cannot meet its obligations.

Why Do Lenders Use Them?

Personal guarantees provide additional security for lenders, particularly on unsecured business loans where no business assets are offered as collateral.

What Are the Benefits?

Providing a personal guarantee can improve access to finance, increase approval chances and sometimes help businesses secure lower interest rates or longer repayment terms.

What Are the Risks?

If the business defaults or becomes insolvent, the guarantor may become personally liable for the outstanding debt, potentially putting personal assets at risk.

What Is a Personal Guarantee?

A personal guarantee is effectively a promise between the borrower and the lender.

If the business cannot repay the finance agreement, the lender can pursue the individual guarantor for repayment.

The guarantee may apply to:

• The full value of the loan
• A fixed percentage of the debt
• Specific obligations within the agreement

Every personal guarantee is different, so it is important to review the terms carefully and seek independent legal advice where necessary.

Limited vs Unlimited Personal Guarantees

There are two main types of personal guarantees.

Limited Personal Guarantee

A limited guarantee restricts liability to a specific amount or proportion of the debt.

This may also include:

• Time limits
• Termination conditions
• Maximum liability caps

Unlimited Personal Guarantee

An unlimited guarantee means the individual could become liable for the full outstanding balance if the business defaults.

This type of agreement carries significantly greater personal financial risk.

Which Business Finance Products Require Personal Guarantees?

Personal guarantees are commonly used across a range of business finance products, including:

• Unsecured business loans
• Asset finance and leasing
• Trade credit agreements
• Invoice finance facilities
• Business overdrafts

They are particularly common where businesses do not have sufficient assets to secure borrowing.

Who Can Provide a Personal Guarantee?

The guarantor is usually:

• A business owner
• A company director
• A shareholder
• A senior executive

In some cases, lenders may require guarantees from multiple directors or owners.

Why Do Lenders Require Personal Guarantees?

Personal guarantees reduce the lender’s risk when providing unsecured finance.

Without physical security such as property or equipment, the lender uses the guarantee as an additional layer of protection.

For businesses, agreeing to a personal guarantee can sometimes help:

• Improve approval chances
• Access larger borrowing amounts
• Secure more competitive rates
• Obtain longer repayment terms

However, business owners should fully understand the personal financial implications before proceeding.

Which Lenders Use Personal Guarantees?

Personal guarantees are widely used across both traditional and alternative business lending markets.

This includes:

• High street banks
• Challenger banks
• Alternative finance providers
• Online business lenders

The requirement often depends on factors such as:

• The loan type
• Business age
• Credit profile
• Available assets
• Borrowing amount

What Happens If a Business Defaults?

If the business cannot repay the finance agreement, responsibility may pass directly to the guarantor.

Potential consequences can include:

Repayment Demands

The lender may formally request repayment of the outstanding debt from the guarantor.

Legal Action

If repayment is not made, the lender may pursue legal action to recover the debt.

Risk to Personal Assets

Depending on the agreement and circumstances, lenders may seek recovery against:

• Personal savings
• Bank accounts
• Vehicles
• Property

Damage to Credit Scores

Defaulting on a personally guaranteed loan can negatively affect both business and personal credit records.

This may make future borrowing more difficult.

What Should You Consider Before Signing a Personal Guarantee?

Before agreeing to any guarantee, business owners should carefully assess the risks and terms involved.

Understand the Scope of Liability

Check whether the guarantee is:

• Limited or unlimited
• Joint or individual
• Time restricted or ongoing

Review the Conditions Carefully

Understand:

• What counts as default
• When the guarantee becomes enforceable
• Whether the lender can pursue immediate repayment

Assess Your Personal Financial Position

Consider how the guarantee could affect your personal finances if the business experienced difficulties.

Seek Independent Advice

It is always sensible to obtain independent legal and financial advice before signing any personal guarantee agreement.

Can You Negotiate a Personal Guarantee?

In some cases, yes.

Depending on the strength of the business and the borrower’s financial position, lenders may agree to:

• Cap liability
• Reduce guarantee amounts
• Include expiry terms
• Limit enforcement conditions

Businesses with stronger trading history or lower risk profiles may have greater negotiating power.

Does a Personal Guarantee Affect Your Credit Score?

Signing a personal guarantee itself does not usually affect your personal credit score.

However, if the business defaults and repayments are missed under the guarantee, this can negatively impact your personal credit file.

Personal Guarantees and Unsecured Business Loans

Personal guarantees are particularly common with unsecured business loans because there is no physical collateral supporting the finance agreement.

For many SMEs, this creates access to funding that may otherwise not be available through traditional secured lending routes.
