In business financing and corporate law, a company charge is a type of security interest granted by a company over its assets or property to secure repayment of a debt or obligation. Charges play a central role in lending and borrowing. In England and Wales, the law governing charges and their registration is contained in the Companies Act 2006 and enforced through Companies House, the official public register. This article explains what charges are, why registration matters, how to comply with the law, key deadlines, practical steps and common legal issues.
What Is a Company Charge?
A charge is a form of security where a company grants a lender a proprietary interest over assets - such as land, equipment, intellectual property or receivables - to secure repayment of a loan or fulfilment of other obligations. Charges help lenders mitigate risk because they may rank ahead of ordinary unsecured creditors in the event of insolvency. Charges can be fixed (attached to specific assets) or floating (covering classes of assets that can change over time).
The principal legal framework for registration of charges is Part 25 of the Companies Act 2006, which sets out requirements for filing information with Companies House to ensure transparency and protect third‑party interests.
Why Register a Charge?
Registering a charge with Companies House creates a public record of the security and establishes its priority against claims from other creditors or in insolvency. If a company fails to register a registrable charge properly:
- the charge may be void against a liquidator, administrator or creditor, meaning the lender cannot enforce its security against company assets in insolvency.
- the lender may lose priority over subsequent secured creditors.
- there may be commercial uncertainty for third parties dealing with the company.
While failure to register is no longer a criminal offence, the commercial consequences can be severe. For that reason it is normal practice to register all plausible charges rather than risk inadvertent non‑registration.
Types of Charges Covered by Registration
Almost all security interests created by a UK company that affect its property or assets are capable of registration. These include, for example:
- Mortgages over land or buildings owned by the company.
- Charges over plant and machinery or other business assets.
- Charges over intellectual property such as patents, trademarks or designs.
- Debentures issued to lenders as evidence of debt.
Only specific exemptions exist - for example, a security deposit given to a landlord may not require registration if it is a true cash deposit securing rent rather than a charge over property. Other statutory exclusions apply in limited circumstances.
Statutory Registration Requirements
The Registration Deadline
Under the Companies Act 2006, when a company creates a registrable charge (including security over assets already subject to a charge if acquired), it must deliver particulars to Companies House within 21 days of the day after creation of the charge. The same applies where an existing charge is taken on newly acquired property. Failing to meet this deadline can affect priority rights.
The 21‑day period is calculated strictly from the creation date of the charge, typically the date the charging instrument (security agreement) is executed. If a charge is not registered on time, there are provisions to apply to the court or Secretary of State to register out of time, though priority may then be determined by the registration date.
Form and Fee
The prescribed form for registering a charge at Companies House is Form MR01 (for companies) or the equivalent for limited liability partnerships (LL MR01). The form must be accompanied by a certified copy of the instrument creating the charge and the appropriate filing fee (for example, £14 for standard online filing). Companies House publicly displays the particulars once accepted.
Copy of Instrument and Inspection
Companies must retain copies of instruments creating charges and any amendments, and make them available for inspection at their registered office (or a Single Alternative Inspection Location). These records support transparency and allow members or creditors to understand encumbrances on company assets.
Satisfaction and Release
Once a debt secured by a charge is fully paid, the charge can be marked as satisfied with Companies House by filing a satisfaction form (MR04) and notifying when charged property has been released. Updating records helps ensure the public register accurately reflects the current security position.
Priority and Legal Effects
Registered charges are entered on the public register of charges maintained by Companies House. Registration does not itself create the security interest but ensures the charge is valid against third parties, particularly in insolvency. A registered charge ranked earlier in time generally takes priority over later charges - critical when multiple lenders take security over the same assets.
Unregistered charges, while potentially valid between the parties themselves, are often treated as void against an insolvency practitioner or creditor, undermining the lender's security in insolvency and reconstruction situations.
Practical Steps to Comply
1. Identify Registrable Security
A company or its legal advisers must identify whether an instrument creates a registrable charge (e.g., mortgage, debenture, fixed/floating charge) affecting company property. If there is any doubt, filing is advisable because there are few disadvantages to registration.
2. Prepare the Required Documents
Gather a certified copy of the charging instrument and complete Form MR01. Ensure the charging document reflects the terms of the security accurately, including the assets charged and names of parties involved. A certificate of compliance or authorisation may be needed, depending on the nature of the instrument.
3. File Within 21 Days
Submit the MR01 and certified copy to Companies House within 21 days of the creation of the charge, along with the correct fee. Online filing is typically faster and reduces risk of delay. After acceptance, Companies House issues a certificate of registration, which evidences registration and is conclusive for priority purposes.
4. Update Company Records
Maintain copies of all charge instruments and related documents at the registered office or alternative inspection location. Ensure any subsequent changes (e.g., variation, release, satisfaction) are also documented and, where appropriate, reported to Companies House.
Common Issues and Risks
Missed Deadlines
Failing to register a charge within the statutory 21‑day period may jeopardise the lender's security priority in insolvency and trigger arguments over enforceability. Early preparation and reporting mitigate this risk.
Exemptions and Uncertainties
Some types of security may not require registration (for example, certain deposit securities), but misunderstanding the law can expose directors and lenders to commercial disadvantage. Advisers should review terms and seek guidance where necessary.
Public Record Integrity
Charges are publicly searchable. Erroneous filings or outdated information can mislead lenders or purchasers. Companies should keep their charge information accurate and update it when obligations are satisfied or security released.
Common Questions from our Readers
Who must register the charge?
Any person “interested in the charge” - typically the company, the lender or an agent - can register it with Companies House. The company itself is primarily responsible for compliance.
Do all charges need to be registered?
Almost all charges created by a UK company must be notified to Companies House, subject to a few narrow statutory exemptions. If in doubt, practice guides and legal advisers recommend registration to protect rights.
What happens if a charge is registered late?
A court application may be made to register out of time, but the charge may rank behind creditors who registered earlier. Prompt filing is therefore essential to secure priority.
Final Thoughts
Charges play a vital role in corporate finance by securing lending and clarifying priority of creditor claims. The statutory scheme under the Companies Act 2006 requires most charges created by companies in England and Wales to be registered with Companies House within 21 days of creation, accompanied by the appropriate form and certified documents. Proper registration protects the lender's security, preserves the value of charged assets in insolvency or enforcement, and ensures transparency to creditors, members and third parties. Understanding the mechanics of charge registration, timing requirements, exemptions and ongoing obligations helps directors, lenders and advisers manage risk effectively and comply with company law.
