Companies House Charges: A Professional Guide to Secured Debt and Corporate Risk

Before extending high-value trade credit, acquiring a target entity, or advising on a distressed restructuring, professionals must establish exactly who holds the primary claim over a company's assets. When a UK limited company secures borrowing against its property, the lender is legally required to record this interest on the public register.

For credit controllers, insolvency practitioners, and corporate lawyers, the charges register provides an unvarnished view of a company's secured debt obligations. It reveals which specific assets are pledged as collateral, the identity of the primary lenders, and the structural hierarchy of the debt. Misinterpreting this data often leads to catastrophic losses for unsecured creditors during an insolvency event.

This guide examines the mechanics of corporate security, the statutory filing requirements, and the investigative techniques required to accurately assess a company's financial exposure.

The Statutory Framework: Part 25 and the 21-Day Rule

The registration of corporate security is governed by Part 25 of the Companies Act 2006. The legislation dictates a strict timeline designed to maintain the integrity and transparency of the public register.

Under s.859A of the Companies Act 2006, companies or their lenders must deliver the particulars of a charge to the Registrar within 21 days of its creation. This 21-day window is an absolute deadline, not a guideline.

Failure to register the charge within this timeframe carries severe legal consequences. An unregistered charge becomes void against a liquidator, an administrator, or any subsequent creditor who successfully registers a competing charge. In practical terms, the lender loses their status as a secured creditor. Should the company enter formal insolvency proceedings, that lender will rank alongside ordinary trade suppliers as an unsecured creditor, drastically reducing their prospect of a meaningful dividend.

If the 21-day deadline is missed, the only remedy is to apply to the court for an extension of time under s.859F. The court will only grant this if the omission was accidental, inadvertent, or if extending the time will not prejudice the position of other creditors. Consequently, lenders and their legal representatives treat the prompt filing of security documents as a critical administrative priority.

Fixed vs Floating Charges: Asset Control and Crystallisation

Interpreting a company's financial health requires a precise understanding of the different types of security. These classifications dictate the extent of the lender's control over the business operations and their priority in a winding-up scenario.

Fixed Charges

A fixed charge attaches to specific, identifiable, and permanent assets. Common examples include freehold land, commercial property, heavy plant machinery, or specialized intellectual property.

The defining characteristic of a fixed charge is control. The borrowing company is legally prohibited from selling, transferring, or disposing of the charged asset without the lender's express written consent. Upon insolvency, the proceeds from the sale of a fixed-charge asset are ring-fenced. After the deduction of direct sale costs, the funds are paid directly to the fixed charge holder to settle the outstanding debt. Only if a surplus remains do the funds cascade down to other creditor classes.

Floating Charges

A floating charge covers a fluctuating class of assets that change in the ordinary course of business. This typically includes raw materials, stock-in-trade, cash at bank, and book debts.

Unlike a fixed charge, the company remains entirely free to buy, sell, and trade these assets without seeking the lender's permission. The charge 'floats' over the asset class until a specific triggering event occurs. These triggers are defined in the loan agreement and usually include a formal default on repayments, the appointment of an administrator, or the issuance of a winding-up petition.

When a trigger event occurs, the charge 'crystallises'. It immediately converts into a fixed charge over the specific assets held by the company at that exact moment, freezing the company's ability to trade them.

The All-Assets Debenture

A debenture is the physical legal document that creates the security interest. In modern corporate banking, a standard facility agreement will almost always be secured by an 'all-assets' debenture. This instrument contains both fixed charges over the company's property and machinery, and a floating charge over its stock and debtors.

By executing an all-assets debenture, the lender effectively takes security over the company's entire undertaking. Before extending significant credit lines, suppliers must conduct a company charge check to determine if a bank already holds a debenture. If they do, the supplier must operate on the assumption that they will recover very little in the event of a collapse.

Deciphering Companies House Filing Codes

The charges register utilises specific alphanumeric form codes to denote the lifecycle of a corporate debt. Recognising these codes instantly is fundamental to accurate due diligence.

| Form Code | Description | Professional Significance |

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

| MR01 | Particulars of a charge | The primary document creating a new security interest. Analysts must review the attached PDF to identify negative pledges and the specific assets caught by the charge. |

| MR02 | Charge over acquired property | Filed when a company purchases an asset (such as a commercial building) that is already subject to an existing mortgage. |

| MR04 | Satisfaction of charge | Filed when a debt is repaid in full or in part. Crucial for confirming that historical security interests have been formally extinguished. |

| MR05 | Release of property | Indicates that specific assets have been released from the charge, usually because they have been sold with the lender's permission, while the main debt remains active. |

Negative Pledges and Inter-Creditor Priorities

A 'negative pledge' is a standard restrictive covenant embedded within almost all modern MR01 filings. It explicitly prohibits the borrowing company from creating any further charges that rank equally with, or ahead of, the existing charge without the primary lender's prior consent.

When reviewing the Companies House register, the presence of a negative pledge serves as a severe warning to subsequent creditors. It ensures that the primary bank maintains absolute priority.

Priority is generally determined by the date of creation, assuming the 21-day registration rule was met. However, sophisticated lenders frequently alter this statutory ranking through private 'Deeds of Priority' or inter-creditor agreements. For example, an invoice discounting provider may require the primary bank to cede priority over the book debts, while the bank retains priority over all other assets. A company displaying multiple active charges from various distinct lenders presents a highly complex risk profile, requiring deep analysis to understand the true hierarchy of debt.

The Statutory Order of Payment in Insolvency

A dangerous misconception among unsecured trade creditors is that a floating charge holder sweeps up all remaining assets. The Insolvency Act 1986 dictates a strict, non-negotiable hierarchy for the distribution of realisations.

When assessing recovery prospects, professionals must apply the following statutory waterfall:

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

2. Insolvency Practitioner Fees: The costs and expenses of the liquidation or administration process.

3. Preferential Creditors: This category includes certain employee claims (arrears of wages, holiday pay) and, crucially, HMRC. Following the reinstatement of Crown Preference in December 2020, HMRC ranks as a secondary preferential creditor for specific tax debts, including VAT, PAYE, and employee NICs.

4. The Prescribed Part: A statutory carve-out from the floating charge realisations, set aside exclusively for unsecured creditors. For charges created after 6 April 2020, this is calculated as 50% of the first £10,000, and 20% of the remaining floating charge asset value, capped at a maximum of £800,000.

5. Floating Charge Holders: The lender receives the remaining balance of the floating charge realisations, up to the value of their outstanding debt.

6. Unsecured Creditors: Trade suppliers, customers, and landlords share any remaining funds on a pro-rata basis. In the vast majority of cases, this results in a dividend of mere pence in the pound.

Worked Example: Assessing Security on a Mid-Market Manufacturer

Consider a composite scenario involving 'Apex Precision Engineering Ltd', a mid-sized manufacturer seeking a £250,000 trade credit facility from a new supplier.

The Investigation:

The credit controller reviews the company's charges register and notes the following history:

• 2018: An MR01 filing for an all-assets debenture granted to a major high-street bank, containing a negative pledge.
• 2021: An MR01 filing for a fixed charge over specific CNC machinery, granted to an asset finance company.
• 2023 (October): A new MR01 filing for a floating charge granted to an alternative, high-interest bridging lender.

The Expert Analysis:

The 2018 debenture is standard and expected. The 2021 asset finance charge indicates normal capital expenditure. However, the October 2023 floating charge to a tier-three bridging lender is a severe red flag.

Because the 2018 debenture contained a negative pledge, Apex Precision Engineering would have required the high-street bank's permission to grant the 2023 charge. The fact that the company had to seek expensive secondary financing suggests the primary bank refused to extend their facility.

Furthermore, the credit controller notes that the company's latest accounts show a significant increase in trade payables. Given the sudden influx of secondary secured debt, the controller decides to execute a winding up petition search. The search reveals that HMRC presented a petition against Apex Precision Engineering just three days ago for unpaid VAT.

The Decision:

The credit controller declines the facility. If the company is wound up, the high-street bank will take the fixed assets. HMRC (as a preferential creditor) will consume the floating assets to settle the VAT debt. The bridging lender will take whatever is left. The unsecured trade creditors will receive nothing.

Red Flags: A Decision Framework for Credit Professionals

Secured borrowing is entirely normal, but specific patterns in the filing history demand immediate scrutiny. Professionals should apply the following framework when reviewing a charges register:

• Sudden Director-Led Security: If a struggling company suddenly grants a floating charge to its own directors or a connected parent company, it is often an aggressive attempt to ring-fence assets and elevate the directors above trade creditors ahead of a planned pre-pack administration.
• Invoice Discounting Charges: A charge granted to a factoring or invoice discounting provider means the company's book debts-usually its most liquid asset-are entirely spoken for. Unsecured creditors cannot rely on the debtor book for recovery.
• Unsatisfied Historical Charges: A lack of MR04 (satisfaction) filings for old loans makes a company appear heavily leveraged. While this is sometimes just poor administrative housekeeping by the borrower's solicitors, it restricts the company's ability to secure new, cheaper financing.
• Alternative Finance Stacking: Multiple recent charges granted to high-interest, short-term lenders indicate severe cash flow distress and an inability to access traditional clearing bank facilities.

Manual Due Diligence vs Corp Intel

Traditionally, assessing a company's secured debt profile is a laborious, manual process. A solicitor or credit manager must navigate the government register, download individual MR01 PDF documents, and manually read through 40-page debenture scans to locate negative pledge clauses. They must then cross-reference these findings with historical accounts to estimate the debt quantum, and separately check The Gazette for insolvency notices.

This manual approach is not only slow but highly vulnerable to human error. A newly filed charge or a sudden court action can easily be missed between periodic credit reviews.

Corp Intel transforms this workflow. The platform aggregates and interprets the charges register, automatically flagging negative pledges, director-led security, and high-risk lending patterns. Rather than relying on point-in-time checks, professionals use the platform to monitor a UK company free. This ensures that the moment a new MR01 charge is filed, or a winding-up petition is presented, the user receives an automated alert, allowing them to freeze credit lines or initiate recovery action days before the wider market reacts.

FAQ

What happens if a lender misses the 21-day registration rule?

Under s.859A of the Companies Act 2006, the charge must be delivered to the Registrar within 21 days. If missed, the charge is legally void against a liquidator or administrator. The lender loses their secured status and becomes an unsecured creditor, though the underlying financial debt remains repayable.

Does a 'fully satisfied' status on the register mean a company is completely debt-free?

No. An MR04 satisfaction notice only confirms that the specific debt facility linked to that exact registration has been settled. The company may still hold other active charges, possess significant unsecured loans, or have substantial trade payables that do not require public registration.

How can I verify the exact monetary amount of debt secured by a charge?

The Companies House charges register details the nature of the security and the assets pledged, but it does not list the live outstanding balance of the loan. To find the monetary value, professionals must cross-reference the register with the 'Creditors: amounts falling due' sections in the company's latest annual accounts.

Can a company register a charge after the 21-day deadline has passed?

Yes, but only with judicial intervention. The company or the lender must apply to the court under s.859F for an order extending the time for registration. The court will only grant this if the failure to file was accidental and does not prejudice other creditors.

What is the difference between a mortgage and a debenture in corporate finance?

A mortgage is typically a specific fixed charge over a single, identifiable asset, such as a commercial property. A debenture is a broader legal instrument that usually contains multiple types of security, including both fixed charges over property and floating charges over the company's general, fluctuating assets.
