When must I file a 2026 UK Confirmation Statement if I changed my SIC code during the year?

You must file the CS01 within 14 days of the end of your annual review period, regardless of whether you changed your Standard Industrial Classification (SIC) code. While the code update is recorded on the statement itself, it does not trigger a new deadline. For most companies in 2026, the review period ends on the anniversary of incorporation or the anniversary of the previous statement's made up date.

Can a 2026 filing be submitted more than 14 days after the review period ends without a penalty?

No, failing to submit the CS01 by the 14 day deadline is a criminal offense under the Companies Act 2006. While Companies House does not usually issue an immediate monetary fine for the first few days of lateness like they do for accounts, persistent failure leads to the company being struck off the register. In 2026, directors can also face personal prosecution and fines for failing to meet this statutory duty.

Which specific 2026 fee applies when filing a second Confirmation Statement in the same calendar year?

The 2026 Companies House fee for a Confirmation Statement is only paid once every 12 months. If you file a second statement within the same payment period to update shareholder information or share capital, the fee is zero (GBP 0). You only pay the standard GBP 34 digital filing fee upon the first filing of your specific 12 month review cycle.

How do I report a 2026 change in persons with significant control (PSC) on the CS01?

You cannot use the CS01 as the primary method to notify Companies House of a PSC change in 2026. You must first file Form PSC01 (for appointments), PSC02 (for legal entities), or PSC04 (for changes to details) within 14 days of the change. The Confirmation Statement then acts as a final verification that the PSC register currently held by Companies House is accurate and up to date.

2026 UK Confirmation Statement: CS01 Filing Deadlines and F…

For 2026, the UK Confirmation Statement (Form CS01) is due no later than 14 days after the end of your company's review period, which is typically the anniversary of incorporation. Every UK Limited company must file this statement at least once every 12 months to verify that the information held at Companies House is accurate, even if there have been no changes to the company structure.

Why is the 2026 Confirmation Statement mandatory?

The Confirmation Statement is a statutory requirement that ensures the public register remains transparent and up to date for investors, lenders, and government agencies. Unlike annual accounts which track financial performance, the CS01 confirms administrative details such as the registered office address, the location of statutory registers, and the list of current officers.

In 2026, maintaining an active status on the register is critical for business continuity. If a company fails to file its statement, Companies House may assume the business is no longer operating and begin proceedings to strike it off the register. This results in the freezing of corporate bank accounts and the transfer of company assets to the Crown through bona vacantia.

How do I determine my 2026 review period?

Your review period is a 12 month block of time that ends on the anniversary of your company's incorporation or the 'made up' date of your last filed Confirmation Statement. For example, if your company was incorporated on May 10, 2025, your first review period ends on May 9, 2026. You then have a 14 day window to submit the filing, making your hard deadline May 23, 2026.

Directors can choose to file a statement earlier than the anniversary date. If you do this, your next 12 month review period starts from the day after that filing date. This is common when a company needs to update its shareholder list or share capital structure immediately for a funding round or sale.

What information must be verified in the 2026 CS01?

When you file the CS01, you are legally 'confirming' that several key data points are correct. If any of this information has changed and was not previously reported via other forms, you must provide the updates during the filing process.

Registered Office Address: This must be a physical address in the same part of the UK where the company was registered (England and Wales, Scotland, or Northern Ireland).
Occupational Details: The names and service addresses of all directors and the company secretary.
SIC Codes: The Standard Industrial Classification codes that describe your business activities.
Statement of Capital: The total number of shares, their aggregate nominal value, and the amount paid up on them.
Shareholder List: A full list of members and the shares they hold as of the statement date.
PSC Register: Details of Persons with Significant Control who own or control more than 25 percent of the company.

2026 Filing Fees and Submission Methods

For 2026, Companies House maintains a significant price difference between digital and paper filings to encourage electronic compliance. Digital filing is faster, results in fewer errors, and provides an immediate receipt of submission.

Filing Method	2026 Fee (GBP)	Processing Time
WebFiling (Digital)	£34	Same day
Software Filing (API)	£34	Same day
Paper Form (CS01)	£62	5 to 10 days

Note that you only pay this fee once per 12 month payment period. If you need to file multiple UK Confirmation Statements in a single year to record frequent shareholder changes, any subsequent filings after the first paid statement are free of charge until your next anniversary.

What happens if the 2026 deadline is missed?

Missing the 14 day filing window for the Confirmation Statement is a criminal offense. Unlike the automatic civil penalties applied for late annual accounts, the sanctions for a late CS01 are focused on the legal standing of the company and the personal liability of the directors.

Initially, Companies House will send a reminder to the registered office. If the statement remains unfiled, the registrar will start the compulsory strike-off process. For directors, the consequences include a strike on their professional record and potential disqualification from acting as a director for any UK company. If your company is facing a strike-off notice, it is imperative to file the UK Ltd compliance documents immediately to halt the process.

2026 Compliance Checklist for UK Directors

To ensure your company remains in good standing throughout 2026, follow these steps at least one month before your anniversary date:

Check the Anniversary: Log into the Companies House service to verify your exact 'Next Statement Due' date.
Verify SIC Codes: Ensure your SIC codes accurately reflect your 2026 business activities, as these are often checked during business bank account reviews.
Audit the PSC Register: Confirm no changes in share ownership have crossed the 25, 50, or 75 percent thresholds without being reported.
Prepare the Fee: Ensure your company payment card is ready or your professional filing service has the necessary funds for the GBP 34 fee.
Review Shareholder Addresses: Update the register of members to reflect correct contact details for all shareholders.
