UK Company Charges and Debentures: A Professional Guide to Corporate Security

Under Part 25 of the Companies Act 2006, a corporate charge must be registered at Companies House within 21 days of its creation. Miss this statutory deadline, and the security becomes void against a liquidator, administrator, or any other creditor. For a lender, this oversight transforms a secured facility into an unsecured risk. For a trade supplier, failing to identify an existing debenture means extending credit to a business that has already pledged its primary assets elsewhere.

Securing debt is the foundation of corporate finance. It permits businesses to access substantial capital at lower interest rates than unsecured borrowing allows. However, for credit managers, insolvency practitioners, and corporate lawyers, understanding the mechanics of these charges is critical for assessing exposure. A company with significant assets completely encumbered by a bank debenture has virtually no headroom for further borrowing. More importantly, in an insolvency event, that company will have minimal funds available for unsecured trade creditors.

This guide examines the legal framework governing UK company charges, the critical distinctions between fixed and floating security, and the strict hierarchy of payments dictated by insolvency legislation.

The Legal Anatomy of a Debenture

The terms 'charge' and 'debenture' are frequently conflated, but they serve distinct legal functions. A charge is the actual security interest granted over an asset. A debenture is the legal instrument or document that creates and records that security interest.

When a limited company or Limited Liability Partnership (LLP) agrees to a secured facility with a bank or private investment firm, the lender will require a debenture. Modern corporate lending typically relies on an 'all-assets' debenture. This document creates a web of security over the entire company, usually combining both fixed and floating charges to capture every available asset class.

Crucially, a debenture often contains a 'negative pledge' clause. This is a contractual restriction preventing the borrowing company from granting any further security interests that would rank equal to or ahead of the lender's charge. If a company breaches a negative pledge, it triggers an immediate default on the facility.

Before entering into a significant commercial contract or extending a large credit line, professionals must perform a comprehensive company charge check to verify exactly what security a business has already granted to third parties.

Fixed Charges vs Floating Charges

UK insolvency law makes a sharp distinction between fixed and floating charges. This classification is not merely academic. It dictates the statutory order of payment in a winding-up scenario, governed primarily by the Insolvency Act 1986.

Fixed Charges and Asset Control

A fixed charge attaches to specific, identifiable assets. The defining legal characteristic of a fixed charge is control. The borrowing company cannot sell, transfer, or otherwise dispose of the charged asset without the express written consent of the lender.

Common assets subject to fixed charges include:

If the borrowing company defaults on its obligations, the lender has the power to appoint a receiver to seize and sell the specific asset. Because the asset is ring-fenced and controlled, a fixed charge provides the highest possible level of security. In an insolvency distribution, fixed charge holders sit at the absolute top of the payment waterfall, recovering their funds directly from the sale of those specific assets.

Floating Charges and Business Continuity

A floating charge is entirely different in its operation. It does not attach to a specific asset but rather 'floats' over a fluctuating class of assets. These are assets that change daily in the ordinary course of business.

Typical assets captured by a floating charge include:

The primary advantage of a floating charge is operational flexibility. The borrowing company is free to buy, sell, and deplete these assets without seeking the lender's permission. A retailer, for instance, could not function if it had to ask its bank for consent every time it sold a unit of stock.

This freedom continues until a 'crystallisation' event occurs. Crystallisation is the legal mechanism by which a floating charge drops down and attaches to the assets exactly as they exist at that specific moment, converting into a fixed charge. Crystallisation is typically triggered by the company entering liquidation or administration, a formal demand for repayment following a default, or a breach of a financial covenant.

Statutory Registration at Companies House

For any corporate charge to be legally enforceable against third parties, it must be registered. Section 859A of the Companies Act 2006 dictates that the particulars of the charge must be delivered to the Registrar of Companies within 21 days beginning with the day after the date of creation.

The standard registration process requires the submission of Form MR01, accompanied by a certified copy of the charge instrument (the debenture deed). Once processed, the details are published on the public Companies House charges register.

Key Companies House Charge Forms

| Form Code | Statutory Purpose | Typical Use Case |

| :--- | :--- | :--- |

| MR01 | Particulars of a charge created by a UK company | Registering a new bank debenture or mortgage |

| MR02 | Particulars of a charge subject to which property has been acquired | Buying a property that already has an existing mortgage attached |

| MR04 | Statement of satisfaction in full or in part of a charge | Filing proof that a secured loan has been entirely repaid |

| MR05 | Statement that part of the property has been released from the charge | Releasing a specific asset from an overarching debenture |

The Consequences of Late Registration

The 21-day deadline is strictly enforced. If a lender or their legal representative misses this window, the consequences under Section 859H of the Companies Act 2006 are severe. The charge becomes entirely void against a liquidator, an administrator, and any creditor of the company. Furthermore, the underlying debt becomes immediately payable on demand.

To rectify a missed deadline, the company or the lender must apply to the High Court for an order extending the time for registration under Section 859F. The court will only grant this if satisfied that the omission was accidental, due to inadvertence, or that it is just and equitable to grant relief. This is an expensive, public, and time-consuming legal process. Worse still, the court order will usually include a caveat protecting the rights of any creditor who acquired a security interest during the period when the charge was unregistered.

The Insolvency Priority Waterfall

When a company fails, the law dictates a rigid hierarchy for distributing realised funds. Understanding this waterfall is essential for any professional assessing credit risk.

1. Fixed Charge Holders: Paid first from the realisation of the specific assets secured by their fixed charge.

2. Insolvency Practitioner Expenses: The costs and fees of the liquidator or administrator.

3. Preferential Creditors: This category includes certain employee claims (arrears of wages and holiday pay). Crucially, HMRC now holds secondary preferential status for specific collected taxes, including VAT, PAYE, and employee National Insurance contributions.

4. The Prescribed Part: A ring-fenced fund set aside from floating charge realisations for the benefit of unsecured creditors.

5. Floating Charge Holders: Paid from the remaining floating charge assets, after the Prescribed Part has been deducted.

6. Unsecured Creditors: Trade suppliers, contractors, and customers. They share pro-rata in whatever funds remain (which is often nothing).

7. Shareholders: The owners of the business, who receive a distribution only if all debts have been paid in full with statutory interest.

Understanding the Prescribed Part

The Prescribed Part is a statutory mechanism designed to ensure that unsecured trade creditors receive at least a marginal dividend when a company fails, even if a bank holds an all-assets debenture.

Under the Insolvency Act 1986, a liquidator or administrator must carve out a portion of the net property realised from floating charge assets. The calculation is strict:

For charges created on or after 6 April 2020, the maximum limit for the Prescribed Part is £800,000. While this provides a safety net, in major corporate failures with hundreds of unsecured suppliers, a pro-rata share of £800,000 often results in a dividend of just a few pence in the pound.

Assessing Risks for Unsecured Creditors

If your firm supplies goods or services on standard credit terms without holding specific security, you are an unsecured creditor. You sit near the very bottom of the insolvency waterfall.

If a prospective client has a heavy debt burden secured by multiple debentures, the risk of non-payment in an insolvency scenario is absolute. Before authorising a large credit limit, you must review their existing security profile. If a company is exhibiting signs of distress, such as delaying payments, you should immediately check any UK company for a winding up petition. If a business is facing a petition from HMRC while simultaneously granting new floating charges to secondary lenders, the risk profile is critical.

Decision Framework: Assessing Corporate Security

Before extending significant credit or entering a long-term supply agreement, follow this standard due diligence framework:

1. Pull the Charges Register: Review the target company's profile at Companies House to identify all outstanding MR01 filings.

2. Identify Negative Pledges: Examine the debenture instruments to see if the company is restricted from seeking alternative finance.

3. Check for Satisfactions: Look for MR04 filings to confirm if historic loans have actually been repaid, or if the register is cluttered with obsolete charges.

4. Assess Asset Headroom: Compare the secured debt against the company's latest filed balance sheet to estimate if any unencumbered assets remain.

5. Implement Ongoing Monitoring: Set up automated alerts to detect any new security granted after your contract begins.

Satisfying a Charge: The MR04 Filing

When a company repays a secured facility in full, the lender must release the security. The company then files a Form MR04 (Statement of satisfaction in full or in part of a charge) at Companies House.

Unlike the strict 21-day rule for creating a charge, there is no statutory deadline for filing a satisfaction. It is entirely optional under the Companies Act. However, it is overwhelmingly in the company's commercial interest to file the MR04 immediately. A clean charges register makes the business infinitely more attractive to future lenders, credit insurers, and cautious suppliers.

You can verify if a company has successfully cleared its debts by reviewing the filing history or checking for statutory notices in The Gazette. If a director claims their business is debt-free, yet the public register shows three outstanding debentures, it indicates either poor administrative governance or an attempt to conceal ongoing liabilities.

Traditional Manual Checks vs Modern Intelligence

Historically, monitoring a company's security profile has been a tedious, manual process. A credit controller or associate solicitor would have to periodically visit the Companies House portal, search for the target entity, navigate to the charges tab, and manually download individual MR01 PDFs. They would then have to read through pages of dense legal text to identify negative pledge clauses or floating charge crystallisation triggers. Because companies can grant new security at any time, a manual check performed in January is entirely obsolete by March.

Corp Intel transforms this workflow. Instead of relying on static, manual searches, professionals use Corp Intel to automatically parse and structure charge data. The platform extracts the critical metadata from debentures, instantly highlighting negative pledges and fixed asset classes. More importantly, by utilising free company monitoring, users receive immediate email alerts the moment a new MR01 or MR04 is filed against a watched client. This ensures that credit teams and legal advisers are reacting to changes in a client's risk profile in real time, rather than discovering a new bank debenture months after the fact.

Composite Scenario: The Facility Default

To understand how these elements interact, consider a composite scenario involving a mid-market manufacturing firm. The firm secures a £2 million facility from a high street bank to fund expansion. The bank registers an all-assets debenture within 14 days via an MR01 filing. The debenture includes a fixed charge over the firm's freehold factory and a floating charge over its inventory and raw materials.

Two years later, the firm loses a major contract and defaults on its facility covenants. The bank issues a formal demand. This demand acts as a crystallisation event. The floating charge immediately drops down, fixing over the inventory held in the warehouse on that specific day. The bank appoints administrators.

The administrators sell the factory (the fixed charge asset) and remit the proceeds directly to the bank. They then sell the inventory (the crystallised floating charge asset). From the inventory proceeds, the administrators must first deduct their own trading expenses, then pay HMRC its secondary preferential claim for unpaid VAT. Finally, they calculate the Prescribed Part from the remaining funds, setting it aside for the trade suppliers. The bank takes the rest to cover its shortfall. The unsecured trade suppliers, who failed to monitor the company's charge register, receive a dividend of just 4 pence in the pound from the Prescribed Part.

Frequently Asked Questions

What happens if a company grants two charges over the same asset?

Priority is generally determined by the date of creation, provided both charges were registered within the strict 21-day statutory window. However, lenders frequently alter this default position by drafting a formal Deed of Priority or Intercreditor Agreement, which contractually dictates who gets paid first regardless of registration dates.

Does a floating charge cover assets acquired in the future?

Yes. A floating charge is designed to cover a fluctuating pool of assets. It captures assets owned by the company at the time the charge is created, as well as any relevant assets acquired in the future, right up until the moment the charge crystallises.

Can a company sell an asset that is subject to a fixed charge?

Not without the express written consent of the charge holder. The defining characteristic of a fixed charge is the lender's control over the asset. If a company sells a fixed charge asset without permission, it is a fundamental breach of the debenture and will trigger an immediate default.

Why do fully repaid loans still appear on the Companies House register?

Filing a statement of satisfaction (Form MR04) is voluntary under the Companies Act 2006. If a company repays a loan but neglects to file the MR04, the charge will remain listed as 'outstanding' on the public register indefinitely, which can negatively impact the company's credit rating.

What is a negative pledge clause?

A negative pledge is a restrictive covenant written into a debenture. It prohibits the borrowing company from granting any subsequent security interests to other lenders that would rank equal to or ahead of the original lender's charge. Breaching this clause usually triggers immediate crystallisation of the floating charge.
