The short answer: a personal guarantee is a promise that you, personally, will repay the business's debt if the business cannot. It removes much of the protection a limited company normally gives its directors. Lenders ask for them on most unsecured business lending, and many directors sign them without reading them closely. This guide explains what you are agreeing to, the different types, and what can be negotiated.
What a personal guarantee is
A limited company is a separate legal person. Normally, if it cannot pay its debts, the directors' personal assets are not at risk. A personal guarantee changes that for one specific debt. If the company defaults, the lender can pursue you for the amount guaranteed, using the same legal routes it would use for any personal debt.
That can mean a demand for payment, a county court judgment and, in serious cases, a charge over property you own or bankruptcy proceedings. A guarantee is not a formality. It is a personal liability that sits alongside your mortgage and other borrowing.
Why lenders ask for them
There are two reasons, and only one is about money.
Recovery. If the business fails, the guarantee gives the lender another source of repayment.
Commitment. A director who has personally guaranteed a loan is far more likely to keep paying it. Lenders know this, which is why they ask even when your personal assets would cover only a fraction of the debt.
For unsecured business loans, a guarantee from the directors is close to standard. For asset finance and invoice finance it is less common but still frequent, particularly for younger businesses.
The four types you will come across
Unlimited guarantee. You guarantee the full debt, including interest, charges and the lender's recovery costs. This is the widest form and the one to read most carefully.
Limited or capped guarantee. Your liability is capped at a fixed amount or a percentage of the debt. This is often the first thing worth negotiating.
Joint and several guarantee. Where several directors guarantee together, the lender can pursue any one of you for the whole amount, not just your share. If one director has more assets, they carry most of the practical risk.
Supported guarantee. The guarantee is backed by a charge over a specific asset, usually your home. This is the highest-risk form, because the lender already has security in place.
What happens if the business cannot pay
The usual sequence is that the business falls behind, the lender demands repayment of the facility, and if the business cannot pay, the lender calls on the guarantee. You then receive a formal demand. Most lenders will discuss repayment arrangements, particularly where the guarantor engages early. Ignoring the demand rarely helps.
If the business enters insolvency, the guarantee does not disappear. It is a separate agreement with you personally. This is one of the most common surprises for directors after a business closes.
A useful exception: the Growth Guarantee Scheme
Under the government-backed Growth Guarantee Scheme, lenders may still ask for a personal guarantee, but your principal private residence cannot be taken as security within the scheme. The government guarantee protects the lender, not you: you remain fully liable for the debt. But for directors worried about putting their home on the line, it is worth knowing.
What you can negotiate
Guarantees are more negotiable than most directors assume, especially when the business is strong and the case is well presented.
A cap. Ask for the guarantee to be limited to a fixed sum or a percentage of the facility.
No charge over your home. Ask whether the guarantee can be unsupported, with no security over your property.
Several rather than joint and several. Where there are several directors, ask for each to be liable only for a defined share.
A reducing guarantee. Ask for the guaranteed amount to fall as the loan is repaid, or to be released once a set amount has been repaid.
A review date. Ask for the guarantee to be reviewed after a period of good conduct, such as 12 or 24 months.
A different structure. Finance secured on an asset or on your invoices sometimes needs a smaller guarantee, or none, because the lender has other security.
Not every lender will agree to every point. But a lender that refuses all of them is telling you something about its appetite for your business.
Spouses, partners and independent advice
If a guarantee is supported by a charge over a jointly owned home, your spouse or partner will usually need to sign too. Lenders will normally require them to take independent legal advice first, so that they understand the risk to the home and are not under pressure. Take that advice seriously. It is there to protect the family, not to slow the deal down.
Getting a guarantee released
A guarantee normally stays in force until the debt it covers is repaid and the lender formally releases it. Some guarantees are written to cover all of the company's liabilities to that lender, not just one loan, which means they can stay live for years. When you repay or refinance a facility, ask for written confirmation that the guarantee has been released. Do not assume it lapses on its own.
Insuring a guarantee you cannot avoid
Where a lender will not move on the guarantee, personal guarantee insurance can limit the damage if it is ever called. We work with Purbeck Insurance Services, the specialist in this cover, and can introduce directors who want a quote.
A Purbeck policy pays a set percentage of the guarantee if the lender calls it in after the business fails:
Secured loans: guarantees of up to £750,000, with 80% cover from the start (up to £600,000).
Unsecured loans: guarantees of up to £500,000, with cover of 60% in year one, 70% in year two and 80% from year three.
Flexible: up to five directors and up to five loans on one policy, and guarantees you have already signed can be insured.
Support: a helpdesk for businesses in financial difficulty, and premiums payable monthly or annually.
Two points to keep in mind. The cover is a percentage, not the whole guarantee, so part of the liability stays with you. And insurance works best after you have negotiated the guarantee down, not instead of it. Our page on personal guarantee insurance sets out the costs and when it is worth having, or you can request a quote from Purbeck directly.
Personal guarantee insurance is provided by Purbeck Insurance Services, which is authorised and regulated by the Financial Conduct Authority. Pinks introduces customers to Purbeck and does not advise on or arrange insurance. We may receive a payment from Purbeck if you take out a policy.
When to walk away
Signing a guarantee is a judgement about your own appetite for risk. Consider stepping back if:
the borrowing is to cover losses rather than to fund growth or a specific asset
the business cannot show how it will repay from its own cash flow
you would be unable to meet the guarantee without selling your home
the lender insists on an unlimited, supported guarantee for a modest facility
In those situations, a smaller facility, a different structure or no borrowing at all may be the better answer. Our guide on what to do after a bank decline covers alternatives.
How Pinks approaches guarantees
We look at guarantees as part of the structure, not as an afterthought. Where a business is strong enough, we look for lenders and products that need a smaller guarantee or none, such as asset finance secured on the equipment, or invoice finance secured on the debtor book. Where a guarantee is unavoidable, we explain exactly what it covers before you sign, and whether insuring it makes sense. Our business funding page covers the wider picture.
Frequently asked questions
Do I have to give a personal guarantee for a business loan?
Not always, but for unsecured business loans it is close to standard. Asset-backed products and stronger businesses can sometimes avoid one or limit it.
Can a lender take my house if I sign a personal guarantee?
If the guarantee is supported by a charge over your home, yes, that is the purpose of the charge. With an unsupported guarantee, the lender would have to pursue you through the courts first. Under the Growth Guarantee Scheme, your main home cannot be taken as security.
Does a personal guarantee end if the company goes into liquidation?
No. The guarantee is a separate agreement with you personally, and the lender can still call on it.
Can I limit a personal guarantee?
Often, yes. A cap, a reducing guarantee or an unsupported guarantee are all worth asking for, particularly for a strong application.
Is personal guarantee insurance worth having?
It can be, particularly where the guarantee is large or supported by your home and the lender will not limit it. Purbeck, the specialist we work with, covers 80% of secured guarantees from the start and builds unsecured cover from 60% to 80% over three years, so check how much of your guarantee is covered and when. Our personal guarantee insurance page explains the costs and trade-offs.
Does my spouse need to sign?
Only if they are a guarantor or the guarantee is supported by a charge over a home they jointly own. In that case they will normally need independent legal advice first.
