If you have ever borrowed through a limited company or an SPV, there is a good chance you have signed a debenture without fully understanding what it does. Debentures are fundamental to secured lending in the UK, yet the term itself causes confusion. Some borrowers assume a debenture is just another name for a mortgage. Others think it only applies to corporate bonds. Neither interpretation is quite right.
This guide explains what a debenture actually is under UK law, how it interacts with property finance, and what borrowers and investors need to know before signing one.
What Is a Debenture?
In UK law, a debenture is a written instrument that acknowledges a debt and creates security over a company’s assets in favour of the lender. It is not the loan itself. Rather, it is the security document that sits alongside the loan agreement and gives the lender enforceable rights over the borrower’s assets if things go wrong.
The Companies Act 2006 uses the term broadly. A debenture can encompass debenture stock, bonds, and any other securities of a company. In everyday commercial lending, however, a debenture almost always refers to the document that creates a combination of fixed and floating charges over the assets of a limited company.
When a lender provides a bridging loan to an SPV, for example, the debenture is the mechanism through which the lender secures its position against everything the company owns. The loan agreement sets out the commercial terms. The debenture sets out the security.
Why the Confusion?
Part of the difficulty is that the word “debenture” means different things in different jurisdictions. In the United States and many other countries, a debenture usually refers to an unsecured bond. In the UK, it is almost always a secured instrument. This distinction matters because UK borrowers reading international content can easily end up with the wrong impression of what they are signing.
Fixed Charges and Floating Charges
A debenture typically creates two distinct types of security interest over a company’s assets: fixed charges and floating charges. Understanding the difference between them is essential.
Fixed Charges
A fixed charge attaches to a specific, identifiable asset. Once a fixed charge is in place, the borrower cannot sell, lease, or otherwise dispose of that asset without the lender’s written consent. The lender effectively has control over what happens to the asset.
Assets commonly subject to a fixed charge include:
- Freehold and leasehold property
- Plant and heavy machinery
- Intellectual property such as patents and trademarks
- Shares held in subsidiary companies
- Specific high-value equipment
In property finance, the fixed charge over the property itself is the most important piece of security. It is registered at the Land Registry as a legal charge and gives the lender priority over that particular asset. This is similar in effect to a mortgage, although the legal mechanism differs when lending to a company rather than an individual.
A fixed charge is powerful security for the lender because it ranks ahead of almost all other creditors in an insolvency. The lender with a fixed charge gets paid from the proceeds of the charged asset before anyone else, including HMRC and employees (in respect of that particular asset).
Floating Charges
A floating charge is quite different. It does not attach to any single asset. Instead, it hovers over a class of assets that changes from day to day. The company can buy and sell assets within that class without needing the lender’s permission.
Assets commonly subject to a floating charge include:
- Trading stock and inventory
- Book debts and receivables
- Cash held in bank accounts
- Raw materials
- Office furniture and minor equipment
The floating charge allows the business to continue operating normally. A company that could not sell its stock or collect its debts without asking the lender first would grind to a halt. The floating charge provides a practical balance between security for the lender and commercial freedom for the borrower.
Crystallisation
The critical moment for a floating charge comes when it crystallises. Crystallisation converts the floating charge into a fixed charge over whatever assets happen to be in the pool at that point in time. This typically happens when the borrower defaults on the loan, when the company goes into administration or liquidation, or when the lender serves a crystallisation notice.
Once a floating charge crystallises, the borrower loses the right to deal freely with those assets. The lender takes control.
It is worth noting that a crystallised floating charge still ranks behind a fixed charge in an insolvency. It also ranks behind preferential creditors such as employees owed wages. This is why lenders prefer to take fixed charges wherever possible and rely on floating charges only for assets that cannot practically be subject to a fixed charge.
What Assets Does a Debenture Cover?
A standard-form debenture in UK commercial lending is deliberately broad. It is designed to catch everything the company owns, both now and in the future. A typical debenture will include security over:
- All real property (freehold and leasehold interests)
- All plant, machinery, and equipment
- All intellectual property rights
- All goodwill of the business
- All book debts and receivables
- All shares and securities held by the company
- All rights under contracts, licences, and permits
- All insurance policies and claims
- All bank accounts and cash
- All other assets and undertakings of the company
This comprehensive approach means that a debenture gives the lender security over the entire business, not just a single property or asset. For borrowers, this is an important point to grasp. Signing a debenture is not the same as granting a mortgage over one building. It is closer to pledging everything the company owns.
How Debentures Work in Property Finance
Bridging Loans and Debentures
When a lender provides a bridging loan to a limited company, the security package almost always includes a debenture. The debenture works alongside the legal charge over the property to give the lender comprehensive protection.
Consider a scenario where an SPV borrows to purchase a commercial property. The lender will typically require:
- A legal charge over the property (registered at the Land Registry)
- A debenture over all company assets (registered at Companies House)
- A share charge over the shares in the SPV
- Personal guarantees from the directors or shareholders
The debenture captures everything the legal charge does not. If the property is the only asset in the SPV, the debenture might seem redundant. But it also covers future assets, contractual rights, insurance proceeds, and the right to receive rental income. These additional layers of security can prove valuable if the loan goes wrong.
The speed at which bridging finance can complete is one of its key advantages. Lenders experienced in this space have streamlined their completion processes so that debenture preparation and registration do not become a bottleneck.
Development Finance and Debentures
In development finance, debentures play an even more critical role. A development project involves a constantly changing pool of assets. Materials arrive on site. Subcontractors carry out work. The value of the property increases as the build progresses. A debenture with a floating charge captures all of this.
The fixed charge covers the land and any existing structures. The floating charge covers the building materials, the contracts with subcontractors, and the increasing value of the works as they progress. Without a debenture, the lender would need to take separate security over each of these elements, which would be impractical.
Development finance lenders also rely on debentures to protect their position if the borrower tries to appoint a different contractor or assign contracts without consent. The debenture gives the lender the right to step in and take control of the project if the borrower defaults.
The Registration Process at Companies House
Every debenture must be registered at Companies House within 21 days of its creation. This requirement exists under the Companies Act 2006 and applies to all charges created by UK companies.
Why Registration Matters
Registration serves two purposes. First, it gives public notice that the lender holds security over the company’s assets. Anyone searching the company’s records at Companies House can see which assets are charged and to whom. Second, registration protects the lender’s priority position. An unregistered charge is void against a liquidator, an administrator, and any creditor of the company.
In practical terms, failing to register a debenture within the 21-day window means the lender loses its security entirely in an insolvency. The debt remains, but the lender becomes an unsecured creditor. Given that unsecured creditors often receive little or nothing in an insolvency, late registration is a serious risk.
What Gets Registered
The registration filing at Companies House includes details of the charge, the assets covered, the date of creation, and the identity of the charge holder. It does not include the full text of the debenture itself. The actual document is held by the lender and the borrower’s solicitors.
When the loan is repaid and the debenture released, the lender must file a satisfaction of charge at Companies House. This removes the charge from the company’s public record. Borrowers should always confirm that this step has been completed after repaying a loan. Outstanding charges on a company’s record can cause problems when seeking new finance or selling the company.
Land Registry Registration
Where the debenture includes a fixed charge over property, separate registration at the Land Registry is also required. This is handled through the standard process for registering a legal charge against the title. A professional valuation will already have been completed as part of the lending process, and the Land Registry registration typically runs alongside the Companies House filing.
What Happens on Default
Default under a debenture can be triggered by a range of events. Non-payment of interest or principal is the most obvious. But debentures also commonly include default triggers for breach of covenants, failure to provide information, change of control of the company, insolvency events, and material adverse changes.
Appointment of Receivers
The most common enforcement step under a debenture is the appointment of a receiver, specifically a Law of Property Act (LPA) receiver or an administrative receiver (though the latter is now restricted under the Enterprise Act 2002).
An LPA receiver is appointed by the lender under the terms of the debenture. The receiver’s primary duty is to the lender, and their job is to take control of the charged assets and realise them to repay the debt. In a property context, this usually means taking control of the property, managing it (collecting rents if applicable), and ultimately selling it.
The appointment of a receiver is a powerful step. Once appointed, the directors lose their authority to deal with the charged assets. The receiver acts as the agent of the company, meaning that any liabilities they incur fall on the company rather than the lender. This is a deliberate legal structure that protects the lender from additional exposure.
Administration
Where a debenture includes a qualifying floating charge (one that covers all or substantially all of the company’s assets), the charge holder has the right to appoint an administrator out of court. Administration imposes a moratorium on creditor action and gives the administrator time to rescue the company or achieve a better outcome for creditors than an immediate liquidation.
For lenders holding debentures, the right to appoint an administrator is a valuable tool. It allows them to take control of the situation quickly without going through the courts. Having a clearly documented exit strategy agreed at the outset of the loan can help both parties avoid reaching this point.
Practical Consequences for Borrowers
Default under a debenture can be devastating for the borrower. The company loses control of its assets. The directors may face personal liability if they have given guarantees. The company’s credit record is damaged, and the costs of enforcement (receivers’ fees, legal costs) are typically added to the outstanding debt.
Understanding how loan-to-value ratios work in bridging finance can help borrowers ensure they maintain adequate headroom and reduce the risk of default. Borrowers who maintain sensible LTV levels throughout the loan term are far less likely to find themselves in enforcement proceedings.
Debentures vs Mortgages
Borrowers often ask how a debenture differs from a mortgage. The answer depends on who the borrower is.
When an individual borrows to buy property, the lender takes a mortgage (a legal charge over the property). The individual does not have “company assets” to charge, so there is no debenture.
When a limited company borrows to buy property, the lender takes both a legal charge over the property and a debenture over the company’s assets. The legal charge secures the specific property. The debenture secures everything else.
The key differences are:
Scope: A mortgage covers one property. A debenture covers all of the company’s assets (including properties).
Registration: A mortgage is registered at the Land Registry. A debenture is registered at Companies House (and the fixed charge elements may also be registered at the Land Registry).
Enforcement: Under a mortgage, the lender’s main remedy is to sell the property. Under a debenture, the lender can appoint receivers, appoint administrators, or take possession of any charged asset.
Flexibility: A debenture captures future assets automatically. A mortgage only covers the specific property named in it.
In the world of unregulated bridging loans to companies, borrowers should expect to encounter both a legal charge and a debenture as standard.
Debentures and Share Charges Together
Lenders to SPVs frequently require a share charge in addition to the debenture. This might seem like duplication, but the two serve different purposes.
A debenture charges the company’s assets from the inside. A share charge charges the shares in the company from the outside, giving the lender security over the equity interest held by the shareholders.
Why does this matter? If the borrower defaults, the lender with a share charge can transfer ownership of the shares to themselves or to a nominee. This gives the lender control of the company without needing to enforce against individual assets. It is often quicker and cheaper than appointing receivers, and it avoids the need to deal with a potentially lengthy asset sale.
In practice, a lender holding both a debenture and a share charge has two parallel routes to recovery. They can enforce the debenture by appointing receivers to sell the assets. Or they can enforce the share charge by taking ownership of the company (and therefore control of the assets within it). This dual approach is standard in property lending to SPVs and gives the lender maximum flexibility.
How Debentures Affect the Borrower
Signing a debenture has several practical consequences that borrowers should understand before proceeding.
Restrictions on Dealing with Assets
While fixed-charge assets cannot be dealt with at all without consent, even the floating-charge assets are subject to restrictions. Most debentures prohibit the company from granting security to other lenders (known as a negative pledge), disposing of assets outside the ordinary course of business, or making distributions to shareholders without the lender’s consent.
These restrictions can limit the company’s freedom of action during the loan term. A company that needs to raise additional finance, for example, may find that its existing debenture prevents it from offering security to a new lender.
Information Obligations
Debentures typically require the borrower to provide regular financial information. This might include management accounts, annual audited accounts, details of any litigation, and notification of any events that could constitute a default. Failing to provide this information on time can itself be a default event.
Insurance Requirements
The borrower will usually be required to maintain comprehensive insurance over all charged assets and to note the lender’s interest on the policies. If the borrower fails to maintain adequate insurance, the lender may have the right to arrange insurance at the borrower’s expense.
Ongoing Compliance
For the duration of the loan, the borrower must comply with all the covenants in the debenture. This creates an administrative burden that smaller companies may not be used to. Having a clear understanding of these obligations from the outset is essential.
Practical Considerations for SPV Structures
SPVs (Special Purpose Vehicles) are widely used in property finance. A borrower sets up a new limited company specifically to hold a property or carry out a development. The SPV borrows the money, buys or develops the property, and repays the loan from the sale proceeds or a refinance.
Why Lenders Like SPVs
From the lender’s perspective, an SPV is attractive because it is a clean entity with no trading history and no pre-existing creditors. The debenture over an SPV captures all of the company’s assets, which in most cases means just the property and associated contracts. There is no risk of the security being complicated by other business activities.
The Double-Edged Sword
For borrowers, SPVs create a clear separation between the property project and their other business interests. The debenture charges the SPV’s assets, not the borrower’s personal assets or other companies. However, lenders usually require personal guarantees from the directors or shareholders of the SPV, which partially removes this protection.
When financing commercial properties through SPV structures, borrowers should pay careful attention to how the debenture interacts with any personal guarantees. The guarantee creates personal liability. The debenture creates company-level security. Together, they give the lender recourse against both the company and the individuals behind it.
Multiple SPVs
Developers who use multiple SPVs across different projects should be aware that each debenture is specific to one company. A lender cannot use a debenture over SPV A to claim assets held by SPV B. However, if the same individuals have given personal guarantees across multiple SPVs, default on one loan could have knock-on effects on others.
Subordination and Priority
When more than one lender holds security over the same company, questions of priority arise. Which lender gets paid first from the proceeds of a particular asset?
The General Rule
Priority between charges generally follows the date of registration. The charge registered first has priority over later charges. This is why lenders insist on registering their debentures at Companies House immediately upon creation.
Intercreditor Agreements
In more complex financing structures, lenders may enter into intercreditor agreements (also called subordination agreements or deeds of priority). These agreements set out the relative priorities of the lenders and regulate how the security proceeds are distributed.
For example, a senior lender providing the main loan facility might require that a mezzanine lender’s charge ranks behind theirs. The intercreditor agreement formalises this arrangement and ensures that the senior lender gets paid first.
Implications for Borrowers
Borrowers seeking additional finance on top of an existing loan need to understand how subordination works. A second lender will only lend if they can obtain adequate security, which may require the first lender to agree to subordinate some of their rights or to share security on agreed terms.
This is relevant in situations where a borrower has taken a bridging loan and subsequently needs additional funds, perhaps for unexpected development costs. The original lender’s debenture may block the company from granting security to a second lender without consent.
Investors considering participating in bridging rounds or convertible loan note structures should also pay attention to how any existing debentures affect their priority position. A convertible loan note holder who ranks behind a debenture holder may find their investment significantly at risk if the company runs into financial difficulty.
Key Takeaways for Borrowers and Investors
For borrowers, the most important thing to understand about a debenture is its scope. You are not just securing the loan against one asset. You are giving the lender security over everything the company owns. This is not unusual or unreasonable in commercial lending, but it requires you to manage the relationship carefully and comply with your obligations throughout the loan term.
For investors and lenders, a debenture is a powerful tool. It provides comprehensive security that adapts to the company’s changing asset base. Combined with a share charge and personal guarantees, it creates a robust security package that protects the investment.
Both parties should ensure that the debenture is properly drafted, properly registered, and properly understood. The cost of legal advice at the outset is trivial compared to the cost of a dispute over security later.
Frequently Asked Questions
What is the difference between a debenture and a loan?
A debenture is not a loan. It is the security document that accompanies a loan. The loan agreement sets out the commercial terms such as the amount borrowed, the interest rate, and the repayment schedule. The debenture sets out the security that the borrower provides to the lender over its assets. You can have a loan without a debenture (an unsecured loan), but you would not normally have a debenture without a corresponding loan.
Can a sole trader or individual sign a debenture?
No. Debentures are specifically for companies (including LLPs). An individual borrower provides security through a mortgage or a legal charge, not a debenture. This is one of the key differences between borrowing personally and borrowing through a limited company. If you are an individual looking at property finance options, a bridging loan secured by a standard legal charge may be the appropriate route.
What happens to the debenture when I repay my loan?
Once the loan is fully repaid, the lender is obliged to release the debenture and file a satisfaction of charge at Companies House. The fixed charge over any property should also be removed from the Land Registry. Borrowers should confirm that both steps have been completed. Outstanding charges on your company’s record can cause delays and complications if you seek new finance or try to sell the company.
Does a debenture affect my personal assets?
A debenture only creates security over the assets of the company. It does not directly affect the personal assets of directors or shareholders. However, lenders almost always require personal guarantees alongside the debenture, and those guarantees do create personal liability. If the company defaults and the security under the debenture does not cover the full debt, the lender can pursue the guarantors personally.
Can I have more than one debenture over the same company?
Yes. A company can grant debentures to multiple lenders. However, each subsequent debenture will rank behind the earlier ones in terms of priority (unless the lenders agree otherwise through an intercreditor agreement). A second lender will usually require the first lender’s consent before a new debenture can be granted, because the original debenture typically contains a negative pledge that prevents the company from granting further security without permission.
Whether you are a borrower preparing to take on finance or an investor evaluating security, understanding debentures is not optional. They are a core part of how commercial lending works in the UK, and a clear grasp of their mechanics will help you negotiate better terms and avoid unpleasant surprises.
