Personal Guarantees for Business Funding: What Directors Need to Know

A personal guarantee can help secure business funding, but it can also expose a director or business owner to personal financial liability if the company cannot repay the debt.

Personal guarantees are commonly associated with business loans and other forms of finance where the lender wants additional protection beyond the financial strength or assets of the company.

They are particularly relevant to unsecured borrowing, newer businesses, larger funding requirements and situations where the lender considers the company alone insufficient security for the finance.

Before signing a personal guarantee, directors should understand exactly how much they are guaranteeing, when the guarantee can be enforced and whether their personal assets could ultimately be at risk.

This guide explains how personal guarantees for business finance work, why lenders ask for them, the potential risks and what to consider before agreeing to one.

What Is a Personal Guarantee?

A personal guarantee is a legally binding agreement under which an individual agrees to become personally responsible for a business debt if the company cannot meet its obligations.

For a limited company, this can be significant.

Normally, the company's debts belong to the company rather than its directors personally.

However, GOV.UK confirms that directors are responsible for company debts they have personally guaranteed.

For example:

Business loan: £250,000
Personal guarantee: £100,000

If the company defaults and the guarantee is enforceable, the guarantor could potentially become personally liable for up to the agreed guaranteed amount, subject to the exact terms of the agreement.

A personal guarantee should therefore never be treated as a routine signature.

Why Do Lenders Ask for Personal Guarantees?

A lender may request a personal guarantee to reduce the risk of providing finance.

This is particularly common where the company:

• Has limited trading history
• Owns few assets
• Has a limited credit history
• Is requesting unsecured finance
• Requires a significant amount of funding
• Presents additional credit risk

GOV.UK states that lenders, landlords and suppliers often request personal guarantees to reduce risk, particularly where a company is newly formed, has limited trading history, has little or poor credit history, or where the transaction involves a significant sum.

A guarantee gives the lender another potential source of recovery if the company cannot repay.

How Does a Personal Guarantee Work?

A simplified process may look like this:

1. The company applies for finance

Suppose ABC Ltd wants a £300,000 business loan.

2. The lender assesses the company

It reviews factors such as:

• Profitability
• Cash flow
• Credit history
• Existing debt
• Security
• Trading history

3. The lender requests a personal guarantee

The lender may agree to provide the finance only if one or more directors personally guarantee some or all of the debt.

4. The director signs the guarantee

The guarantee becomes part of the funding arrangement.

5. The company makes repayments

If the company meets all of its obligations, the guarantee may never need to be enforced.

6. The company defaults

If the company cannot repay, the lender may be able to pursue the guarantor according to the terms of the guarantee.

The British Business Bank describes a personal guarantee as an agreement under which a business owner or director becomes personally liable for repaying borrowing if the business defaults or becomes insolvent.

How Much Can a Personal Guarantee Cover?

A personal guarantee does not necessarily cover the full amount of the loan.

Depending on the lender and transaction, it may cover:

• 100% of the debt
• A fixed cash amount
• A percentage of the borrowing
• Certain amounts plus interest and costs

The British Business Bank notes that some lenders may seek a guarantee for the full loan amount, while others may request only a proportion.

Example

Business loan: £500,000
Guarantee: 25%

Potential guaranteed amount:

£125,000

However, the wording of the agreement matters.

The director should confirm whether the liability is truly limited to £125,000 or whether additional items such as:

• Interest
• Legal costs
• Recovery costs

can also be added.

What Is a Capped Personal Guarantee?

A capped personal guarantee limits the guarantor's liability to an agreed amount.

For example:

Loan: £400,000
Guarantee cap: £100,000

The director's guarantee is limited according to the wording of the agreement rather than covering the entire £400,000.

A cap can reduce personal exposure considerably.

Before signing, confirm:

• The exact cap
• Whether interest is included
• Whether legal costs sit inside or outside the cap
• Whether the cap reduces as the loan is repaid
• When the guarantee terminates

Do not assume the personal liability automatically falls in line with the outstanding loan balance unless the document says so.

What Is an Unlimited Personal Guarantee?

An unlimited guarantee can expose the guarantor to substantially more risk.

Rather than being limited to a specific amount, liability can potentially extend to the full guaranteed debt and applicable costs according to the agreement.

For larger finance arrangements, the difference between:

£100,000 capped exposure

and:

an unlimited guarantee

is significant.

The terms should be reviewed carefully before signing.

What Is a Joint and Several Personal Guarantee?

Where several directors or shareholders provide guarantees, the guarantees may be joint and several.

GOV.UK explains that under a joint and several guarantee, multiple guarantors can each be liable for the full debt.

For example:

Three directors each provide a joint and several guarantee relating to a £300,000 liability.

That does not necessarily mean each director is responsible for exactly £100,000.

Depending on the wording, the lender may potentially pursue one guarantor for the full guaranteed amount and leave the guarantors to resolve contributions between themselves.

This is particularly important in businesses with multiple directors or shareholders.

Secured vs Unsecured Personal Guarantees

Personal guarantees can themselves be structured differently.

GOV.UK identifies both secured and unsecured personal guarantees.

Secured personal guarantee

A guarantee may be supported by a specific personal asset.

For example, a charge could potentially be taken against property.

Unsecured personal guarantee

The guarantee is based on the individual's personal obligation rather than a specific pledged asset.

That does not mean personal assets are necessarily protected if the guarantee is later enforced.

Directors should understand exactly what security, if any, supports the guarantee.

Does an Unsecured Business Loan Require a Personal Guarantee?

It can.

This is one of the most important distinctions for directors to understand.

An unsecured business loan normally means the lender is not taking security over a specific company asset.

It does not necessarily mean the directors have no personal exposure.

The British Business Bank says personal guarantees are commonly required for unsecured business loans because the lender does not have business assets supporting the facility.

This means a business could have:

• No property pledged by the company
• No machinery pledged by the company

but still have:

• A director personally guaranteeing the debt

Read Secured vs Unsecured Business Finance: Key Differences for a wider comparison.

What Happens If the Business Cannot Repay?

If the company defaults, the lender may take steps to recover the outstanding debt.

Exactly what happens depends on:

• Loan agreement
• Guarantee wording
• Security
• Amount outstanding
• Lender recovery process

Where a valid personal guarantee exists, the lender may seek repayment from the guarantor.

The Insolvency Service warns that personal assets such as:

• Property
• Vehicles
• Savings
• Investments

could potentially be used to settle personally guaranteed company debts.

In serious circumstances, where personal liabilities cannot be met, bankruptcy may become a risk.

Can a Personal Guarantee Put Your Home at Risk?

Potentially.

The precise risk depends on the structure and whether the guarantee is secured against property.

However, even an unsecured guarantee creates personal liability.

If the lender obtains a personal judgment and the debt remains unpaid, personal assets could potentially be exposed through the legal recovery process.

This is one reason personal guarantees deserve independent legal consideration before signing.

Does a Personal Guarantee Affect Your Credit Score?

Simply signing a guarantee does not necessarily mean your personal credit score immediately falls.

However, the British Business Bank notes that if the company defaults and the guarantor subsequently fails to meet personal payment obligations, the individual's credit position could be affected.

A lender may also conduct personal credit checks when assessing whether it is willing to accept the guarantee.

Are Personal Guarantees Enforced Immediately?

Not necessarily.

How and when a lender acts depends on:

• The agreement
• Nature of the default
• Security available
• Recovery process

The government has noted that guarantees are typically intended to provide lenders with additional protection and may be used as part of recovery when a business defaults.

However, directors should never assume a guarantee is merely symbolic.

If it is legally enforceable, the personal obligation is real.

Why Would a Director Agree to a Personal Guarantee?

Despite the risks, there are circumstances where directors accept guarantees because doing so allows the company to obtain funding it could not otherwise access.

Potential benefits include:

Access to finance

The lender may only be prepared to lend if additional personal support is provided.

Larger funding amounts

A guarantee may provide enough additional comfort for the lender to consider a larger facility.

Better finance terms

The additional lender protection may potentially help secure more favourable pricing or terms.

The British Business Bank and Insolvency Service both recognise that providing a guarantee may help a business access funding or better finance terms than would otherwise be available.

The issue is therefore not that personal guarantees are always inappropriate.

It is whether the commercial benefit justifies the personal risk.

What Should Directors Check Before Signing a Personal Guarantee?

There are several important questions to ask.

1. What Amount Am I Guaranteeing?

Establish whether the guarantee covers:

• Entire loan
• Fixed amount
• Percentage

Do not rely on verbal explanations.

Check the agreement.

2. Is the Guarantee Capped?

A clear cap can materially reduce potential personal exposure.

Understand whether interest and recovery costs sit inside or outside it.

3. Does the Guarantee Reduce as the Loan Is Repaid?

Suppose the original guarantee is £200,000.

If the company repays half the loan, does the guaranteed exposure reduce?

Not necessarily.

Check whether the guarantee has a reducing structure.

4. When Does the Guarantee End?

This is particularly important if:

• You sell your shares
• You resign as a director
• The loan is refinanced
• Ownership changes

Do not assume leaving the business automatically releases you from an existing guarantee.

The UK government's recent consultation material specifically identified the lifecycle of personal guarantees as an issue because individuals may overlook continuing guarantees after events such as selling or retiring from a business.

5. Is It Limited to One Facility?

Check whether the guarantee relates to:

• One specific loan

or potentially:

• Wider current and future liabilities with the same lender.

This can significantly affect your exposure.

6. Are Several Directors Providing Guarantees?

If so, determine whether liability is:

• Several
• Joint
• Joint and several

Do not assume liability is automatically divided equally.

7. What Happens if the Business Defaults?

Understand the enforcement process.

Ask what circumstances allow the lender to call on the guarantee.

8. Is Personal Security Being Taken?

Check whether personal assets are specifically being charged.

Should You Get Independent Legal Advice?

Yes, it is sensible to consider independent specialist legal advice before agreeing to a personal guarantee.

The Insolvency Service specifically recommends considering independent specialist advice because of the potential consequences for personal assets.

The British Business Bank also notes that some financial institutions require guarantees to be witnessed by a solicitor who confirms that the guarantor has received independent legal advice.

Legal advice can help you understand:

• Scope of the guarantee
• Liability cap
• Enforcement provisions
• Security
• Release provisions
• Joint and several liability
• Continuing obligations

This is particularly important for substantial guarantees.

Can You Negotiate a Personal Guarantee?

Potentially.

A lender does not have to accept changes, but aspects that may be discussed include:

Reducing the amount

For example:

Instead of guaranteeing 100% of the facility, request a defined percentage or fixed monetary cap.

Reducing the guarantee over time

Liability could potentially reduce as the loan balance falls or once certain milestones are achieved.

Agreeing a release date

For example, the guarantee could potentially terminate after:

• A period of successful repayments
• The business reaches a specified financial position
• Alternative security becomes available

The British Business Bank recommends considering whether the guarantee can be negotiated, including seeking an earlier end date or reduced liability after a successful repayment record.

Limiting the guarantee to one facility

Avoid unnecessarily broad obligations where possible.

Example of Negotiating a Personal Guarantee

Suppose a lender requests:

Business loan: £500,000
Initial guarantee request: £500,000

A director might seek:

Guarantee cap: £150,000

with the guarantee reducing after the company has repaid a defined amount of the loan.

Whether the lender accepts this depends on:

• Business strength
• Creditworthiness
• Other security
• Negotiating position

The point is that directors should understand whether the proposed guarantee is fixed or negotiable rather than automatically accepting the first structure presented.

What Is Personal Guarantee Insurance?

Personal guarantee insurance is designed to provide some protection to guarantors if a guarantee is called upon.

The British Business Bank notes that such policies exist and may cover a proportion of the guaranteed debt, subject to the policy terms.

However, insurance should not be treated as making a guarantee risk-free.

Check:

• Percentage of liability covered
• Policy exclusions
• Waiting periods
• Premium
• Maximum payout
• Circumstances in which claims can be rejected

Independent insurance advice may be appropriate.

Alternatives to a Personal Guarantee

If you are uncomfortable providing a personal guarantee, alternative funding structures may be available.

Secured Business Finance

Providing business assets as security may reduce or change the personal guarantee requirement.

Potential security might include:

• Property
• Machinery
• Equipment

Invoice Finance

Companies with significant B2B receivables may be able to access funding against unpaid invoices.

Read Invoice Finance: Factoring and Invoice Discounting Explained.

Asset Finance

Equipment and machinery can potentially be financed against the underlying asset.

Read Asset Finance: How It Works for UK Businesses.

Asset-Based Lending

Existing business assets may support borrowing.

Equity Finance

Instead of borrowing, the company can raise capital by issuing shares.

This avoids conventional loan repayment and personal guarantee requirements, although existing owners give up some equity.

Grants

Eligible businesses may be able to access non-repayable funding for certain projects.

Read Business Grants and Government Funding in the UK.

The British Business Bank similarly identifies secured loans, invoice finance, asset-based lending, equity and grants among possible alternatives where owners are reluctant to provide personal guarantees.

Personal Guarantees When Buying a Business

Personal guarantees can also arise in acquisition finance.

For example, a buyer may raise:

Purchase price: £1.5 million

• Buyer capital: £300,000
• Acquisition debt: £900,000
• Deferred consideration: £300,000

The acquisition lender may consider:

• Target EBITDA
• Cash flow
• Assets
• Buyer contribution
• Security

and may also request a personal guarantee from the buyer.

This creates an important distinction.

The buyer is not only investing their initial £300,000.

They could also be taking on additional contingent personal exposure through the guarantee.

Anyone structuring a debt-funded acquisition should therefore consider the guarantee alongside the:

• Purchase price
• Debt level
• Repayment profile
• Security
• Equity contribution

What Happens to a Personal Guarantee if You Sell the Business?

Do not assume selling the company automatically cancels a guarantee.

If the guaranteed facility remains outstanding, the original guarantee may potentially continue unless the lender formally releases the guarantor or the facility is repaid or refinanced according to its terms.

This is something sellers should address as part of the transaction.

Before completion, establish:

• Which guarantees exist
• Which facilities they relate to
• Whether those facilities will be repaid
• Whether the lender will provide formal release

A verbal understanding that the new owner will “take over the loan” is not the same as being formally released by the lender.

Does Resigning as a Director Cancel a Personal Guarantee?

Not automatically.

A guarantee is a contractual obligation.

Resigning as a director does not necessarily terminate it.

The director should obtain confirmation from the lender if a guarantee is intended to be released.

This is another reason the exit and release provisions should be understood before the guarantee is originally signed.

Personal Guarantee vs Limited Liability

Limited company status generally means company debts and personal debts are separate.

A personal guarantee creates an exception because the director voluntarily accepts personal liability for a specified company obligation.

GOV.UK explicitly states that directors become responsible for money owed by the company where they have personally guaranteed that debt.

That is why the words limited liability should not be interpreted as meaning a director can never become personally liable for company borrowing.

When Might a Personal Guarantee Be Reasonable?

A personal guarantee may be commercially reasonable where:

• The business is financially sound
• The funding has a clear purpose
• Repayments are comfortably affordable
• The guarantee amount is proportionate
• The director understands the risks
• The funding creates meaningful commercial value

For example, a profitable company might provide a limited guarantee to obtain finance for equipment that materially increases capacity.

When Should You Be Particularly Cautious?

Extra caution may be appropriate where:

• The business is already struggling to repay debt
• Cash flow is highly uncertain
• The guarantee is unlimited
• The amount is disproportionate to personal finances
• Several facilities are covered
• The director does not understand the wording
• The business is borrowing primarily to cover continuing losses

A personal guarantee should not make otherwise unaffordable borrowing sensible.

Personal Guarantee Checklist for Directors

Before signing:

• Confirm the amount guaranteed.
• Check whether liability is capped.
• Check whether interest and costs are included.
• Understand whether liability reduces as the loan is repaid.
• Check whether the guarantee is secured against personal assets.
• Understand joint and several liability.
• Confirm which facility or facilities are covered.
• Understand what constitutes default.
• Check when the guarantee ends.
• Understand what happens if you sell or leave the business.
• Consider whether the terms can be negotiated.
• Consider independent legal advice.
• Compare alternative finance structures.
• Make sure the underlying business can comfortably support the debt.

Should You Sign a Personal Guarantee?

There is no universal answer.

A personal guarantee can help a company access funding that might otherwise be unavailable and may sometimes improve the terms offered.

But the additional funding comes with additional personal risk.

Before agreeing, understand:

• The amount
• The liability
• The assets potentially exposed
• The duration
• The release terms
• The business's ability to repay

Most importantly, do not look only at the likelihood that the business will repay successfully.

Consider what the guarantee means if things do not go according to plan.

If the personal exposure is unclear, obtain appropriate independent legal advice before signing.

Understand Your Personal Exposure Before Funding an Acquisition

When buying an established business, your financial commitment may extend beyond the cash you invest on completion.

If acquisition debt is supported by a personal guarantee, you could also be taking on additional contingent personal liability if the acquired business is unable to meet its repayments.

That makes it important to assess the full funding structure, not just the purchase price and your initial equity contribution.

At Valius, we help buyers discover established businesses for sale and navigate the wider acquisition journey, including valuation, due diligence, funding and deal structure.

Before progressing a debt-funded acquisition, understand what security and guarantees may be required, how much personal exposure they create and whether the target business can comfortably support the proposed borrowing after completion.

A deal that works commercially should also work financially without placing disproportionate risk on the buyer.
