What a personal guarantee actually is
A personal guarantee is a legal commitment by a director or owner to repay a business debt from personal assets if the business itself cannot. It sits outside the company's own liability, meaning that if the business fails and cannot repay the facility, the lender can pursue the guarantor personally, potentially including their home if it is used as security or if a charge is registered against it separately.
Guarantees are common on unsecured or lightly secured lending to smaller and younger businesses, because the lender has limited recourse to company assets alone and wants a second source of repayment. Larger, well secured facilities are less likely to require one, or require one for a smaller proportion of the debt.
Limited vs unlimited guarantees
A limited guarantee caps your exposure at a stated amount or percentage of the facility, for example 20% of the outstanding balance. An unlimited guarantee exposes you to the full outstanding debt plus costs and interest with no cap. Wherever there is room to negotiate, a limited guarantee is worth pushing for, particularly where there are multiple directors and the lender is asking each of them to guarantee the whole facility jointly and severally.
Joint and several guarantees mean the lender can pursue any one guarantor for the full amount, not just their proportionate share, leaving the guarantors to sort out contribution between themselves afterwards. This detail is often glossed over but matters considerably if a business relationship later breaks down.
When lenders ask for one and when they do not
Asset finance and invoice finance facilities sometimes avoid the need for a full personal guarantee because the lender already holds strong recourse to the specific asset or the receivables themselves. Unsecured cash flow loans and revolving credit facilities to smaller companies almost always require one. Commercial mortgages typically require a guarantee for a portion of the loan even where the property itself is the primary security, reducing as the loan to value falls.
It is reasonable to ask a lender directly whether a guarantee can be avoided or reduced by offering additional security elsewhere, such as a debenture over company assets, before accepting an unlimited personal guarantee as the only option.
What happens if the business defaults
If the business defaults and the lender calls on the guarantee, they will typically first exhaust reasonable recovery from the business and any specific security before pursuing the guarantor, though the exact sequence depends on the wording of the agreement. Guarantors should read the demand carefully and take independent legal advice before agreeing to any repayment plan, since guarantee disputes are common and lenders are generally open to structured settlements rather than immediate legal action.
Guarantee insurance exists in the market and can cover a portion of personal exposure for a premium, though it is not universally available and is worth discussing with a broker or adviser at the time the facility is arranged rather than after a default has occurred.
Negotiating the guarantee before signing
The best time to negotiate the scope of a guarantee is before the facility is agreed, not after. Points worth raising include capping the amount, limiting it to one director rather than all of them, excluding the family home specifically, and agreeing that the guarantee reduces in proportion as the facility balance reduces over time. Lenders will not always concede all of these, but a broker who structures the deal with this in mind at the outset has more room to negotiate than one trying to renegotiate terms after an offer letter has already been issued.
Frequently asked questions
Can I negotiate a personal guarantee down after signing?
It is far harder once the facility is in place. Negotiation has the most leverage before the offer is accepted, which is why it should be raised at the structuring stage.
Does a personal guarantee affect my personal credit file?
The guarantee itself typically does not appear on your personal credit file unless it is called and a default is registered against you personally as a result of non-payment.
Is my home automatically at risk under a personal guarantee?
Only if the guarantee is unlimited or the lender takes a specific legal charge over the property, or pursues a county court judgment that is later enforced against it. It is not automatic, but the risk should be taken seriously and discussed with a solicitor.
