File a Confirmation Statement (CS01) with Companies House

Filing a Confirmation Statement (CS01) with Companies House is a key legal requirement for every UK company. It keeps your company’s public record up to date and ensures compliance with the law. Missing this filing can lead to penalties or even the company being struck off the register. This guide explains what a Confirmation Statement is, why it matters, and how to file it correctly.

What is a Confirmation Statement?

A Confirmation Statement is a document that UK companies must submit to Companies House at least once every 12 months. It confirms that the information held about the company is accurate and up to date. This includes details such as:

• Registered office address

• Directors and company secretary details

• Shareholders and share capital

• People with significant control (PSC)

  
  

The Confirmation Statement replaced the Annual Return in 2016, simplifying the process but keeping the core purpose intact: maintaining accurate company records.

Why Filing a Confirmation Statement is Important

Companies House uses the information in the Confirmation Statement to keep the public register current. This register is accessible to anyone and is often used by banks, investors, suppliers, and customers to verify company details.

Failing to file the Confirmation Statement on time can result in:

• Late filing penalties

• Loss of good standing which can affect creditworthiness

• Possible strike-off from the Companies House register, which means the company legally ceases to exist

  
  

Keeping your company’s information accurate also helps avoid misunderstandings or legal issues related to company ownership or management.

When and How to File Your Confirmation Statement

You must file the Confirmation Statement within 14 days of the anniversary of your company’s incorporation or the date of the last Confirmation Statement filed. For example, if your company was incorporated on 1 March 2023, your first Confirmation Statement is due by 15 March 2024.

Steps to File

1. Gather your company information

   Check your current details on the Companies House website or your last filed Confirmation Statement. Make sure you have the latest information about directors, shareholders, and registered office.

   
   

1. Access the Companies House online service

   You can file online using the Companies House WebFiling service. You will need your company authentication code to log in.

   
   

2. Complete the Confirmation Statement form

   Review the pre-filled information and update any changes. Confirm the details are correct.

   
   

1. Pay the filing fee

   The fee for filing a Confirmation Statement online is £13. If you file by paper, the fee is £40.

   
   

2. Submit the form

   Once submitted, you will receive a confirmation email from Companies House.

   
   

Filing by Paper

While online filing is faster and cheaper, you can still file a paper Confirmation Statement by downloading the form CS01 from the Companies House website, completing it, and posting it with the fee.

Common Mistakes to Avoid

• Missing the deadline: Mark your calendar to avoid late filing penalties.

• Incorrect or incomplete information: Double-check details before submitting.

• Using an outdated authentication code: If you lose your code, request a new one from Companies House.

• Ignoring changes in company structure: Update details about new directors, shareholders, or PSCs promptly.

  
  

What Happens After You File

Once Companies House processes your Confirmation Statement, the updated information becomes publicly available on the company register. This transparency helps maintain trust with stakeholders and supports legal compliance.

Tips for Managing Your Confirmation Statement Filing

• Set reminders: Use digital calendars or accounting software to remind you of filing deadlines.

• Keep records updated throughout the year: Don’t wait until the deadline to update company information.

• Use professional help if needed: Accountants or company secretarial services can handle filings and ensure accuracy.

• Check Companies House guidance: Their website offers detailed instructions and FAQs.

  
  

What if Your Company Changes During the Year?

If your company undergoes changes such as new directors, share transfers, or changes in registered office, you must update these details with Companies House. Some changes require separate filings, but the Confirmation Statement is the opportunity to confirm all details are correct.

For example, if you appoint a new director in July, you must file a separate appointment form within 14 days. Then, when you file your Confirmation Statement, you confirm that the director list is accurate.
