Negative pledge clauses: why an unsecured lender can still restrict future security

A negative pledge is a contractual promise that the borrower will not grant security over assets to another creditor except where the loan agreement permits it. The lender may have no fixed charge over those assets today, yet the clause can still restrict how the company raises future secured finance.

The clause protects the lender from being structurally weakened

If an unsecured lender advances money and the borrower later grants another bank first-ranking security over every valuable asset, the original lender's recovery position can deteriorate sharply.

A negative pledge prevents or limits that outcome by requiring the borrower to avoid new security unless it falls within agreed exceptions.

Read how broadly security is defined

The covenant can cover mortgages, charges, liens and transactions having a similar economic effect. The definition can reach arrangements management does not think of as conventional bank security.

Ask legal advisers whether retention arrangements, receivables sales, asset finance or cash collateral fall within the clause.

Most agreements contain permitted-security baskets

The company can be allowed to grant normal-course liens, purchase-money security, existing disclosed charges or security below a monetary threshold.

Use those baskets deliberately and track utilisation. A £1 million permitted-security limit can be consumed gradually across many small asset-finance deals.

Check the clause before taking new finance

Procurement can agree equipment finance while treasury is unaware that the structure creates security restricted by another facility.

Include a negative-pledge check in every new borrowing or leasing approval. It is easier to seek consent before signing than after the new lender is ready to draw.

Lenders can consent to specific new security

A strong borrower can request consent or an amendment where new secured finance supports growth and does not materially harm the existing lender.

Get the waiver in writing and confirm whether it is transaction-specific or changes the covenant permanently.

The Companies House charge register is useful but not enough

Public charge searches show registered company security, but a negative pledge itself is a contractual restriction and may not appear as a separate public charge.

Treasury therefore needs both the public security register and an internal covenant register when considering new financing.

Worked example: an unsecured lender provides £2 million and the facility prohibits new security except up to £250,000 of permitted asset finance. The company later wants £600,000 of equipment finance secured on new machinery. Even though the original lender has no charge over the machine, the borrower can still need consent because the negative pledge restricts the new security.

Track security baskets by transaction date and outstanding amount. A facility can allow £500,000 of permitted security, but a company that has already used £450,000 cannot assume another £200,000 lease is automatically permitted.

Review negative pledge clauses during acquisitions. Acquired subsidiaries can already have local charges that were not present when the original facility was signed, potentially requiring consent or post-closing clean-up.

Worked example: a company has an unsecured £3 million lender facility containing a negative pledge and wants to finance £800,000 of solar equipment with a new lender taking security over the panels. The new security can still need consent even though the first lender has no registered fixed charge.

Keep a covenant checklist inside procurement approval for financed assets. Procurement teams often negotiate leases or vendor finance without realising that the legal structure grants security that treasury has promised not to create.

Review existing permitted-security baskets before each transaction. A basket may be measured by original amount, outstanding amount or another contractual method, and using the wrong basis can lead the company to exceed it accidentally.

During refinancing, negotiate negative-pledge flexibility that matches the business model. Asset-heavy businesses needing regular equipment finance should not accept a blanket restriction that forces lender consent for routine capital expenditure unless pricing compensates for the constraint.

Include subsidiaries in the review where the negative pledge extends to the wider group. A subsidiary granting local security can breach a parent facility even if the parent itself signs nothing.

Keep legal opinions or lender consents with the security register. Years later, finance should be able to show why a particular equipment lease or property charge was permitted rather than relying on memory.

Check negative pledges before entering supplier retention-of-title, receivables assignments or unusual financing arrangements. Even where they are not traditional registered charges, the agreement can define security broadly enough to require review.

Review guarantee arrangements too. Some negative-pledge or debt covenants also restrict guarantees for another group company, meaning treasury can need consent even where no new asset charge is granted.
