The Signature That Follows You Home: A Personal Guarantee Review for UK Directors

Personal guarantees rarely announce themselves. They sit in schedules, side letters and credit applications, signed at completion when attention is on rent, interest and covenants. Years later, a refinancing, lease renewal or supplier review can turn a half-remembered signature into a live demand. For UK SME directors, the task is not to assume the worst but to establish exactly what has been promised, to whom, for how much and for how long.

Why a guarantee audit belongs on the 2026 board agenda

As 2026 renewal conversations begin, lenders and landlords are revisiting covenants and security. A guarantee given in a quieter period may still be enforceable, and an all-monies wording can capture borrowing that did not exist when the document was signed. The audit is a control exercise: it gives the board a register of exposures, supports negotiations and prevents surprises at the point of exit or succession.

Understand what you signed

A guarantee is a promise to meet another party's obligation if the principal debtor does not. An indemnity is often broader, creating a primary liability rather than a secondary one. The distinction matters because defences available to a guarantor may not apply to an indemnitor. Directors should also distinguish:

• a capped guarantee, limited to a stated sum or period;
• an all-monies guarantee, which can cover present and future liabilities;
• a joint and several guarantee, allowing the lender to pursue any one signatory for the whole amount;
• a continuing guarantee, which remains live until formally released;
• a secured guarantee, backed by a charge over personal assets such as a home.

Locating the paperwork

The main facility letter is only the starting point. Guarantees are frequently buried in ancillary documents. A director's search should include:

• facility agreements, overdraft letters, invoice finance and asset finance documents;
• commercial leases, licences, deeds of variation and assignments;
• supplier credit applications and trading terms;
• group cross-guarantees and parent company support letters;
• board minutes, resolutions and written consents;
• side letters, emails and solicitors' completion bibles;
• personal guarantee insurance policies and correspondence.

Finance teams should ask the bank relationship manager, broker, landlord's solicitor and former advisers for copies. Where a guarantee has been released, the release letter should be on file. A verbal assurance is not a release.

Mapping caps, triggers and release conditions

Build a single guarantee register. For each entry, record the counterparty, date, instrument, amount cap, whether it is all-monies, whether liability is joint and several, the trigger for demand, any expiry or burn-off provision, security granted and the notice address. This register should be reviewed by the board at least annually and updated whenever facilities or leases change.

Red flags include:

• an all-monies clause with no cap or time limit;
• guarantee wording tucked into a credit application or standard terms;
• automatic extension when a facility is varied or renewed;
• joint and several liability with a co-director who has since left;
• cross-default provisions linking one guarantee to other debts;
• no release mechanism on refinancing or sale;
• a guarantee of subsidiary or group debts that the director does not control;
• a personal charge over a home or savings;
• indemnity language that removes usual guarantor protections.

Deciding what to do

Once the register is complete, the board can prioritise. Options include negotiating a cap, a time limit or a burn-off after a period of good performance; seeking release on refinancing, sale or retirement; substituting corporate security where appropriate; or insuring the exposure. Personal guarantee insurance can be useful in some circumstances, but policies vary in scope, exclusions and cost, and should be reviewed with a broker and legal adviser. Any negotiation should be documented in writing, and a release should be obtained from the counterparty, not inferred from conduct.

Keep the register alive

A guarantee is not a filing-cabinet issue. It should be discussed when facilities are renewed, when a director retires or sells shares, and when the company takes on new borrowing or leases. Board minutes should record the review, and the register should be part of the exit pack. Directors should also consider how a guarantee affects personal borrowing, estate planning and any personal charge already granted.

A practical audit sequence

1. Gather every facility, lease, credit application and side letter.
2. Build the register and classify each guarantee by cap, scope and trigger.
3. Quantify the realistic exposure, not just the headline limit.
4. Identify which guarantees can be released, capped or insured.
5. Take legal and broking advice before approaching counterparties.
6. Negotiate in writing and diarise every renewal or release date.
7. Report the position to the board and keep evidence.

The objective is not to eliminate risk but to see it clearly. A director who knows where every guarantee sits is better placed to negotiate, to plan for succession and to avoid discovering the extent of a personal commitment at the worst possible moment.
