What is the 2026 filing fee for a UK Confirmation Statement submitted via the Companies House online portal?

As of early 2026, the standard fee for a digital Confirmation Statement (Form CS01) is 34 GBP per year. This fee covers a 12 month review period. If you submit multiple updates within that same year, you only pay the fee once. However, paper filings cost significantly more, currently set at 62 GBP, though Companies House continues to phase out paper submissions in favor of digital-first requirements under the Economic Crime and Corporate Transparency Act (ECCTA).

Can a 2026 UK Confirmation Statement be filed before the review period ends?

Yes, you can file a 2026 Confirmation Statement at any time during your review period. This is often done when a company needs to report changes to its share structure or PSC register immediately rather than waiting for the anniversary of incorporation. Filing early restarts your 12 month review clock from the date of the early filing. It does not shorten your legal obligation but shifts the future due date to coincide with the anniversary of your last submission.

What is the 14 day grace period for UK Confirmation Statements in 2026?

In 2026, you must deliver your Confirmation Statement to Companies House within 14 days of the end of your review period. The review period usually ends on the anniversary of your company incorporation or the anniversary of your last filing. For example, if your review period ends on July 10, 2026, your filing must be successfully processed by July 24, 2026. This window is strictly enforced, and missing it can trigger automatic compliance notices from the Registrar.

Which specific company details must be confirmed in the 2026 CS01 filing?

The CS01 requires you to verify or update the registered office address, the principal business activity (SIC code), the statement of capital (including total nominal value and number of shares), and the Register of People with Significant Control (PSC). Under 2026 rules, you must also confirm that the company is acting lawfully and that all director identities have been verified through the government's authorized biometric or intermediary systems as required by the ECCTA.

What happens if a UK company director fails to submit the Confirmation Statement by the 2026 deadline?

Failing to file the 2026 Confirmation Statement is a criminal offense committed by the directors and the company secretary. Companies House can prosecute individuals and fine them personally. Additionally, the Registrar may assume the company is no longer trading and begin the 'strike-off' process to remove the company from the register. Once a company is struck off, its assets (including bank balances and intellectual property) automatically become the property of the Crown through bona vacantia.

2026 UK CS01 Guide: Confirmation Statement Deadlines and Ru…

A UK Confirmation Statement (Form CS01) is a mandatory annual filing that verifies the accuracy of a company's data on the public register at Companies House. In 2026, this filing must be submitted within 14 days of your review period ending, typically the anniversary of your company's incorporation.

Why is the Confirmation Statement mandatory in 2026?

The Confirmation Statement ensures that the public record reflects the current reality of your business, including who owns it and where it operates. Unlike annual accounts, which focus on financial performance, the CS01 focuses on corporate structure. Under the 2026 regulations following the full implementation of the Economic Crime and Corporate Transparency Act (ECCTA), this filing also serves as a certification that the company’s intended future activities are lawful.

Every UK Limited Company (Ltd), Limited Liability Partnership (LLP), and Community Interest Company (CIC) must file this regardless of whether they are active, dormant, or non-trading. For international founders, this is the primary mechanism for maintaining your company's 'Active' status on the register and avoiding involuntary strike-off.

How do I determine my 2026 filing deadline?

Your 2026 filing deadline is calculated based on your 'review period,' which lasts 12 months. This period begins on the day of your company's incorporation or the day after your last Confirmation Statement was filed. You have exactly 14 days from the end of this period to deliver the CS01 to Companies House.

Event	Timing and Rule
Review Period Duration	12 Calendar Months
Filing Window	14 Days after the period ends
Filing Fee (Digital)	34 GBP (2026 Rate)
Mandatory Updates	SIC Codes, PSC Register, Capital

If you incorporate a company on March 15, 2026, your first review period ends on March 14, 2027. Your first Confirmation Statement would then be due by March 28, 2027. Many founders choose to align this with their UK tax and accounting cycles to simplify administrative oversight.

What information do I need to verify on Form CS01?

Form CS01 requires you to confirm that all information currently held by Companies House is up to date. If changes occurred during the year that were not reported previously, you must include them in the statement. Key data points include:

Registered Office Address: This must be an 'appropriate address' where documents can be delivered and acknowledged. Use of a simple PO Box is no longer permitted in 2026.
Standard Industrial Classification (SIC): You must provide at least one code that describes your business activity.
Statement of Capital: You must confirm the total number of shares, their aggregate nominal value, and the amount paid or unpaid on those shares.
Shareholder Information: For non-traded companies, you must provide a full list of shareholders if it was not submitted in the previous review period.
PSC Register: You must verify the details of individuals with significant control (usually those holding more than 25% of shares or voting rights).

What are the new identity verification rules for 2026?

Under the 2026 compliance framework, you cannot successfully 'confirm' your company details if the directors and People with Significant Control have not completed their identity verification. All new and existing directors must have their identities verified either directly through Companies House using biometric software or through an Authorized Corporate Service Provider (ACSP).

If you are a non-resident director, you must ensure your verification is linked to your unique director ID before the CS01 is submitted. Failing to do so will result in the statement being rejected, which can lead to late filing penalties and potential prosecution. This system was designed to prevent the use of straw man directors and to increase the transparency of UK entities.

What happens if the 2026 deadline is missed?

Missing the Confirmation Statement deadline is a serious compliance failure. Unlike annual accounts, there is no automatic financial penalty that increases daily, but the legal consequences are more severe. The Registrar of Companies has the power to strike your company off the register entirely.

When a company is struck off, it ceases to exist as a legal entity. All business bank accounts are frozen, and any assets owned by the company are transferred to the UK government. To restore a company after a strike-off for failure to file is a costly and time-consuming court process. Furthermore, directors who consistently fail to file can be disqualified from acting as a director for up to 15 years.

2026 Compliance Checklist for UK Founders

To ensure your UK entity remains in good standing, follow this sequence each year:

Monitor the Review Period: Log into the Companies House service to check the 'Next Statement Due' date.
Verify PSC Changes: Confirm if any shareholder has crossed the 25%, 50%, or 75% threshold in the last 12 months.
Check SIC Codes: Ensure your business activity still matches the SIC codes on file, especially if you have pivoted your services.
Confirm Identity Status: Ensure all new directors appointed during the year have completed the 2026 identity verification process.
Pay the Levy: Ensure you have the 34 GBP fee available for the digital submission.

Managing these requirements is part of the standard UK business formation and maintenance routine for every entrepreneur.
