The UK Confirmation Statement: Statutory Duties, ECCTA 2023 Reforms, and Due Diligence Risks

Under Section 853A of the Companies Act 2006, every UK limited company and Limited Liability Partnership (LLP) must verify its corporate data at least once every 12 months. For corporate solicitors, accountants, and credit risk analysts, the confirmation statement (Form CS01) is far more than an administrative formality. It is the definitive public record of a company's capital structure, shareholder distribution, and ultimate beneficial ownership.

Failure to file a confirmation statement accurately and on time triggers severe statutory consequences, ranging from criminal prosecution of directors to compulsory strike-off proceedings. Furthermore, the regulatory framework governing this filing has fundamentally shifted following the implementation of the Economic Crime and Corporate Transparency Act 2023 (ECCTA). The Registrar of Companies now possesses enhanced powers to query, reject, and penalise misleading filings.

This briefing outlines the statutory mechanics of the confirmation statement, analyses the new ECCTA requirements, and provides a practical framework for auditing CS01 filings during corporate due diligence.

The Legal Framework: Section 853A and the Shift from Annual Returns

Introduced by the Small Business, Enterprise and Employment Act 2015, the confirmation statement replaced the legacy annual return (Form AR01) in June 2016. The legislative intent, codified in Part 24 of the Companies Act 2006, was to simplify compliance by shifting the burden from restating data to verifying existing data.

While the annual return required a company to submit a full snapshot of its officers, capital, and shareholders every year, the confirmation statement operates on a 'check and confirm' basis. Directors must review the current information held on the Companies House register and formally declare that it is accurate. If changes have occurred during the review period, the company must either update the data within the CS01 itself or file the appropriate event-driven forms concurrently.

Core Data Verified in Form CS01

When submitting Form CS01, the company officers must verify several critical data points. A common error among inexperienced directors is assuming the CS01 can be used to update all company information. In reality, the form handles specific updates, while others require separate statutory filings.

Impact of the Economic Crime and Corporate Transparency Act 2023

The Economic Crime and Corporate Transparency Act 2023 (ECCTA) transformed Companies House from a passive repository of information into an active, investigative registrar. This legislation directly impacts how confirmation statements are filed and scrutinised.

Since 4 March 2024, every company must provide two new pieces of information on their first confirmation statement filed after this date. Failure to provide these will result in immediate rejection of the filing.

1. Registered Email Address: Companies must supply an appropriate email address where the Registrar can send official communications. This address is kept on a private register and is not visible to the public.

2. Lawful Purpose Statement: The company must confirm that its intended future activities are lawful. This declaration must be made every year on the CS01.

Beyond these specific additions, ECCTA empowers the Registrar to challenge suspicious filings, demand supporting evidence for changes in share capital, and share data cross-departmentally with law enforcement and HMRC.

Filing Deadlines and the Review Period

The statutory timeline for the confirmation statement is strict. A company's 'review period' typically begins on the date of incorporation and lasts for exactly 12 months. Once this period ends, the company has a 14-day window to lodge the statement and pay the requisite fee.

| Feature | Statutory Requirement | Post-May 2024 Fee |

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

| Review Period | 12 months from incorporation or last filing | N/A |

| Filing Window | 14 days after the review period ends | N/A |

| Online Filing | Mandatory for most entities | £34 |

| Paper Filing | Permitted only in specific exemptions | £62 |

Filing early is permitted and often necessary during corporate transactions. When a company files a CS01 early, the date of that filing becomes the start of a new 12-month review period.

Consequences of Non-Compliance

Failing to file a confirmation statement is a criminal offence under Section 853L of the Companies Act 2006. The repercussions for the corporate entity and its officers are severe and escalate rapidly.

Criminal Prosecution

Every officer of the company is personally liable for ensuring the CS01 is filed. Companies House actively prosecutes directors for non-compliance. Conviction results in a criminal record, a fine, and potential disqualification from acting as a director under the Company Directors Disqualification Act 1986.

Compulsory Strike-Off

If the Registrar believes a company is no longer carrying on business due to missing filings, they will initiate compulsory strike-off action under Section 1000 of the Companies Act 2006. A notice is published in The Gazette, granting two months before the company is dissolved. Upon dissolution, the company ceases to exist, its bank accounts are frozen, and its assets become 'bona vacantia', passing to the Crown.

For creditors and suppliers, monitoring these notices is critical. To ensure a counterparty is not facing dissolution due to administrative failure or insolvency, credit controllers must routinely perform a winding up petition search to identify underlying legal or financial distress before extending terms.

Withdrawal of Banking and Credit

Financial institutions use automated API feeds from Companies House to monitor their commercial clients. An overdue confirmation statement frequently triggers an automatic review of the client's risk profile. Banks may freeze accounts to prevent the dissipation of assets ahead of a potential strike-off. Similarly, credit reference agencies will immediately downgrade the company's credit score, causing suppliers to withdraw trade credit.

The Due Diligence Perspective: How Professionals Read a CS01

For corporate finance advisers, private equity analysts, and M&A solicitors, the confirmation statement is a foundational document for due diligence. It provides the most recent snapshot of a target company's ownership and capital structure.

When reviewing a CS01, professionals look for discrepancies between the public record and the internal statutory registers (the cap table) provided by the target's management. A common red flag is a mismatch in the Statement of Capital. If a company has issued new shares (Form SH01) during the year but failed to update the shareholder list on the subsequent CS01, the public record will show a disconnect between the total shares in issue and the shares allocated to specific individuals.

Furthermore, the CS01 is the primary vehicle for tracking changes in ultimate beneficial ownership via the PSC register. Sudden, unexplained changes in PSCs can indicate an undisclosed transfer of control, warranting deeper investigation into the transaction's commercial rationale and anti-money laundering (AML) implications.

Beyond equity ownership, a comprehensive risk assessment must evaluate the company's debt profile. Relying solely on the CS01 provides an incomplete picture of corporate health. Professionals must concurrently execute a company charge check to identify any mortgages, debentures, or fixed and floating charges secured against the company's assets. This ensures the equity value implied by the confirmation statement is not subordinated to undisclosed secured creditors.

Worked Example: How an Outdated CS01 Derailed a Series A Funding

Consider a composite scenario involving a high-growth technology firm, 'Apex Dynamics Ltd', seeking a £5 million Series A investment. The term sheet is signed, and the venture capital fund's legal team commences due diligence.

The target's management provides an internal cap table showing the two founders holding 40% each, with an angel investor holding the remaining 20%. However, when the VC's solicitors pull the latest CS01 from Companies House, the public record shows the founders holding 50% each, with no mention of the angel investor.

Investigation reveals that the angel investor acquired their shares via a transfer from the founders six months prior. The company executed the stock transfer form and updated its internal register of members. However, they failed to file an early CS01 to reflect this transfer on the public record.

This discrepancy halts the transaction. The VC cannot proceed until the public record matches the internal cap table, as the public register dictates legal ownership certainty. Apex Dynamics Ltd is forced to draft and file an immediate confirmation statement, paying the filing fee and delaying the funding round by several days while waiting for the Registrar to process the update. Had the transaction involved a complex restructuring or a debt-for-equity swap, the delay and legal costs to rectify the public record would have been substantially higher.

Traditional Manual Review vs The Corp Intel Approach

Historically, monitoring confirmation statements and corporate filings required significant manual effort. Solicitors and credit controllers would rely on diary systems, periodically visiting the Companies House WebCHeck service, downloading individual PDF documents, and manually comparing the current Statement of Capital against the previous year's filing to spot undocumented share transfers.

This manual methodology is highly susceptible to human error. It relies on point-in-time checks, meaning a company could file a misleading CS01, or default on its filing obligations entirely, weeks before a professional manually checks the record. By the time the default is noticed, the bank may have already frozen the target's accounts, or a competitor may have identified the compliance failure.

Corp Intel replaces this fragmented process with automated, structured data extraction. Rather than manually downloading PDFs, professionals use our platform to track filing deadlines, extract shareholder data into actionable formats, and receive immediate alerts the moment a target company files an update or misses a statutory deadline. By integrating free company monitoring into their workflow, advisory firms ensure they are notified of capital changes, PSC updates, and impending strike-off actions in real time, allowing them to advise clients proactively rather than reacting to public record discrepancies.

Decision Framework: Auditing a Target Company's Confirmation Statement

When conducting due diligence on a UK corporate entity, practitioners should apply the following framework to audit the confirmation statement:

1. Verify the Filing Status: Confirm the date of the last CS01. Is the company currently in default? If the next filing date is overdue, halt the transaction until the target rectifies the breach.

2. Cross-Reference the Statement of Capital: Compare the total number of shares and aggregate nominal value on the CS01 against the most recent set of filed accounts and any subsequent SH01 (Return of Allotment) forms.

3. Reconcile the Shareholder List: Ensure the shareholder distribution on the CS01 matches the internal register of members provided by the target's management. Look for undocumented share transfers.

4. Audit the PSC Register: Check that the individuals listed as Persons with Significant Control on the CS01 align logically with the shareholder list. If a shareholder holds 30% of the equity but is not listed as a PSC, investigate the discrepancy.

5. Check the ECCTA Declarations: For statements filed after 4 March 2024, verify that the lawful purpose statement has been made and that the company has not received a rejection notice for failing to provide a registered email address.

6. Review Concurrent Filings: Check if the CS01 was filed alongside other forms (e.g., AD01, AP01). Ensure these changes are reflected in your due diligence report.

FAQ

Q: Can a company file a confirmation statement early?

A: Yes. Filing early is common practice before a corporate transaction, funding round, or sale. Doing so resets the 12-month review period, meaning the next statement will be due 12 months from the new filing date.

Q: What is the difference between an annual return and a confirmation statement?

A: The annual return (AR01) required a company to provide a full restatement of all its data every year. The confirmation statement (CS01) requires the company to verify that the data already held by Companies House is correct, and only provide updates where changes have occurred.

Q: What happens if a company files a CS01 but the information is incorrect?

A: The company must file a second confirmation statement (Form RP04) to correct the data. Under the ECCTA 2023, the Registrar has increased powers to penalise companies for providing false or misleading information on the public register.

Q: Do dormant companies have to file a confirmation statement?

A: Yes. Every limited company and LLP, regardless of its trading status, must file a confirmation statement at least once every 12 months to maintain its place on the public register.

Q: Can I update the registered office address directly on the CS01?

A: No. While you can update the SIC code and shareholder information directly on the CS01, changes to the registered office address require a separate Form AD01, which must be filed before or at the same time as the confirmation statement.
