Simply, a debenture is a legal document that gives a lender a charge over a borrower’s assets. The holder of the charge has a legal right to collect their debt if the borrower defaults on the terms of the loan. Debentures are a critical aspect of the financial landscape, particularly in the business lending space.
For many growing businesses, a debenture is a sign of financial strength. It shows that lenders trust your company’s assets enough to secure larger, lower-cost loans. This can unlock bigger funding lines while allowing you to retain full ownership and control of the business.
Types of Debenture Charges
There are two primary types of debenture charges that a borrower may encounter: fixed and floating
Fixed Charge
A fixed charge is a legal claim that a lender holds over a borrower’s assets. In this scenario, the lender becomes the primary creditor for the borrower, which means that in the event of a default, the lender has the right to take ownership of the asset and sell it to recover the outstanding debt.
Fixed charges apply to a wide range of assets, such as freehold and leasehold properties, building fixtures, trade fixtures, fixed plants, machinery, and motor vehicles. This type of security is commonly used in asset finance arrangements. It is crucial to note that while there is an existing fixed charge on the property, the borrower cannot sell or trade the asset without the lender’s permission.

Floating Charge
A floating charge is a legal claim that a lender holds over all the assets of a borrower. Unlike a fixed charge, a floating charge is not attached to any specific asset. Instead, it is a general charge that applies to all of a company’s assets. It may be a class of specific assets such as raw materials, stock, or cash, making it particularly useful for working capital finance.
For example, in invoice finance, a floating charge often covers a company’s debtors book because it changes constantly as invoices are raised and paid. This makes it particularly useful for working capital finance.
Floating charges are unique in the sense that it is assumed that the asset may change in nature over time, but the borrower is granted permission to sell or move the asset as part of their normal business process. However, if a lender decides to enforce a debenture, they can convert the floating charge to a fixed charge on the company’s asset. At that point, the borrower cannot sell or move the asset without the lender’s permission.
Deed of Priority
When lenders have outstanding debentures on a business, they will agree on a priority of payments among themselves. This is a deed of priority. When liquidation or insolvency occurs, floating charge holders have priority over unsecured debtors when payments are allocated.
When Businesses Use Debentures
Debentures are commonly required for equipment finance, property acquisitions, working capital facilities, and invoice finance arrangements. Directors can also use debentures to protect personal loans they make to their own companies. By registering a debenture, a director becomes a secured creditor, which means their loan is repaid ahead of HMRC and other unsecured creditors if the company enters insolvency.
For established SMEs, a debenture often forms part of a broader growth strategy. It allows a business to leverage assets to raise working capital, fund expansion, or invest in property without diluting ownership.
Key Differences
Debenture vs Loan: A debenture is the security document; the loan agreement sets repayment terms. They work together, not separately.
Debenture vs Shares: Debentures secure assets without granting ownership. Shares provide voting rights and dividends but rank after debenture holders in insolvency.
Debenture vs Personal Guarantees: Debentures secure company assets only. Personal guarantees make directors personally liable. Many lenders require both.
Enforcement
If a business defaults, lenders can take possession of charged assets, appoint receivers, or place the company into administration. This process typically starts with a default notice, followed by formal enforcement action if the breach isn’t remedied.
Why a Debenture Matters to Borrowers
For borrowers seeking funding, debentures play a critical role in determining the type of business loan they can access. A lender’s decision to secure a debenture depends on the borrower’s creditworthiness and the nature of the loan. Debentures provide lenders with an additional level of protection, which can lead to lower interest rates and more favourable repayment terms for borrowers.
Debentures also provide transparency and clarity to both the borrower and lender. By identifying specific assets, the lender can clearly define the collateral securing the loan, while the borrower can better understand the level of risk involved in borrowing.
A well-structured debenture can strengthen your borrowing position. It shows lenders that your business has tangible value and a solid foundation. This confidence often translates to better terms, longer repayment periods, and access to larger funding facilities.
