Personal Guarantees and UK Invoice Finance 2026

Market Invoice is an independent UK invoice finance comparison site that ranks 87 UK invoice finance providers.

Personal guarantees on UK invoice finance protect providers against fraud, ledger misrepresentation and director-led trading down rather than ordinary business losses. Most providers require a director PG capped at 25-100% of the facility limit, but some established providers will waive or cap PGs for larger businesses with a strong debtor profile, audited accounts and no concentration risk, at thresholds that vary by provider. Selective spot factoring from Hydr, Triver and Sonovate rarely requires PG at all.

Personal Guarantee Invoice Finance Uk FAQ

Do I need a personal guarantee for UK invoice finance?

Most UK invoice finance facilities require a personal guarantee from at least one director, particularly at facility size below £500,000 or for businesses with limited trading history. The PG is typically capped at 25-100% of facility limit. Some established providers will consider waiving or capping PGs for larger businesses with audited accounts, balanced debtor concentration and a solid trading record; the threshold varies by provider (see the table below). Selective spot factoring from fintechs (Hydr, Triver, Sonovate) rarely requires PG.

When can a personal guarantee on invoice finance be called?

PGs are typically called for fraud (fake invoices, misrepresented ledger, undisclosed customer disputes), serious misconduct, or director-led trading down where the provider can demonstrate the director acted improperly. PGs are NOT typically called for ordinary trading losses or business failure that wasn't director-caused. The standard wording protects providers against bad acts rather than bad luck.

How do I negotiate out of a personal guarantee on UK invoice finance?

Three negotiation levers: (1) demonstrate audited accounts with 2+ years clean trading history, (2) show debtor concentration is balanced (no single customer dominating the sales ledger), (3) offer alternative security (all-asset debenture, intercompany guarantee, increased reserves on the facility). Best timing: at facility renewal rather than initial setup. Most providers will reduce PG cap to a fixed amount (e.g. £100,000) rather than fully waive on first ask.

What's the difference between a PG and a debenture on invoice finance?

Personal guarantee = director's personal liability for facility losses up to PG cap. Debenture = security over all company assets (cash, receivables, plant and machinery, IP) but no director personal liability. Most established providers prefer a debenture-only structure for £1m+ businesses with strong financials. Debenture gives the provider security over company assets without exposing directors personally.

Can a sole trader avoid a personal guarantee on invoice finance UK?

Sole traders are personally liable for business debts by default (unlimited liability), so a separate PG isn't usually needed. Some sole trader invoice finance facilities still include a contractual personal guarantee for clarity but it adds little to the existing legal liability. Ltd company invoice finance is where PG negotiation matters most.

Do all UK invoice finance providers require personal guarantees?

No. Selective spot factoring from Hydr, Triver, Sonovate and Hydr typically doesn't require personal guarantees on sub-£50k advances because the funder takes risk per invoice. Some larger providers will waive PGs entirely for qualifying businesses, with thresholds that vary by provider. The PG requirement is therefore a question of provider, facility size and your business profile rather than a universal rule.
