Confirmation Statement CS01: Essential Guide for UK Companies

Confirmation Statement cs01

In the dynamic world of business, ensuring compliance with legal requirements is paramount. For companies registered in the UK, one such critical compliance document is the Confirmation Statement cs01. This document plays a vital role in keeping your company’s information up-to-date and maintaining transparency with Companies House. Understanding the intricacies of the CS01 form and its significance can save your business from potential penalties and keep you in good standing with regulatory authorities.

Understanding the CS01 Form

The CS01 form, also known as the Confirmation Statement, is a mandatory filing requirement for all UK companies. It replaced the Annual Return (AR01) in June 2016, aiming to simplify the process of updating Companies House with accurate company information. The cs01 form must be filed at least once every 12 months, even if the company details remain unchanged. This document ensures that the public register holds accurate and current information about the company’s directors, shareholders, and registered office address.

Purpose and Importance of the Confirmation Statement CS01

The primary purpose of the Confirmation Statement CS01 is to confirm that the information held by Companies House about your company is correct and up-to-date. It serves as a snapshot of your company’s status and key details, ensuring transparency and accountability. By filing the CS01 form, companies demonstrate their commitment to maintaining accurate records, which is crucial for stakeholders, investors, and regulatory bodies.

Failure to file the Confirmation Statement CS01 on time can lead to severe consequences. Companies House may impose fines and penalties, and persistent non-compliance can even result in the company being struck off the register. Therefore, timely and accurate filing of the CS01 form is essential to avoid these repercussions and to ensure the smooth operation of your business.

Information Required for the CS01 Form

When preparing to file the Confirmation Statement CS01, it’s important to gather all the necessary information to ensure a seamless process. The CS01 form requires the following details:

Company Information

This includes the company’s registered name, registration number, and the date of the confirmation period. The confirmation period is the 12-month period since the last confirmation statement or, for new companies, since incorporation.

Company Directors

You must provide the names and details of all company directors. This includes their full name, date of birth, nationality, occupation, and residential address. It’s crucial to ensure that this information is accurate and up-to-date.

Company Secretary (if applicable)

If your company has a secretary, you need to include their details as well. This includes their full name and service address. Although having a company secretary is not mandatory for private companies, if one is appointed, their details must be included.

Registered Office Address

The registered office address is the official address of the company where legal documents and correspondence are sent. This address must be a physical location in the UK and cannot be a P.O. Box.

Shareholders and Shareholding Structure

You need to provide details about your company’s shareholders and the distribution of shares. This includes the names of shareholders, the number and class of shares they hold, and any changes in shareholding since the last confirmation statement.

People with Significant Control (PSC)

Identifying People with Significant Control (PSC) is a crucial aspect of the Confirmation Statement CS01. A PSC is someone who owns or controls more than 25% of the company’s shares or voting rights, or who has significant influence or control over the company. Accurate information about PSCs must be included in the CS01 form.

Filing the Confirmation Statement CS01

Filing the Confirmation Statement CS01 can be done online or by post. The online filing process is quicker and more efficient, allowing you to update your company’s information in real-time. To file online, you need to create an account with Companies House and provide the necessary details. The online fee for filing the CS01 form is £13, while the postal fee is £40.

Online Filing

Online filing is the preferred method for many companies due to its convenience and cost-effectiveness. Here are the steps to file the CS01 form online. First, log in to Companies House WebFiling. Access the WebFiling service on the Companies House website and log in to your account. Next, select the Confirmation Statement. Choose the option to file a Confirmation Statement CS01 and enter your company’s registration number. Then, review and update information. Carefully review the pre-populated information about your company. Make any necessary updates or corrections to ensure accuracy. After that, provide PSC information. Enter details about People with Significant Control (PSC) if there have been any changes since the last confirmation statement. Finally, submit and pay. Once you have reviewed and updated all the necessary information, submit the form and pay the £13 fee using a credit or debit card.

Postal Filing

If you prefer to file by post, you can download the CS01 form from the Companies House website, fill it out manually, and send it along with the £40 fee. Here are the steps for postal filing. First, download and print the CS01 form. Visit the Companies House website, download the CS01 form, and print it out. Next, complete the form. Fill in the required information, including company details, directors, shareholders, and PSC information. Ensure all information is accurate and up-to-date. After that, include payment.

Ensure you send it well before the deadline to avoid any delays or penalties.

Deadlines and Penalties

The Confirmation Statement CS01 must be filed at least once every 12 months. Companies House sends a reminder when the filing deadline approaches, but it is ultimately the company’s responsibility to ensure timely submission. Missing the deadline can lead to penalties, starting with a late filing penalty and escalating to potential criminal prosecution for the company’s officers.

Striking Off

Persistent non-compliance with the filing requirements can lead to the company being struck off the Companies House register. This means the company ceases to exist as a legal entity, and its assets become the property of the Crown. Reinstating a struck-off company is a complex and costly process, so it’s crucial to avoid this outcome by filing the CS01 form on time.

Common Mistakes to Avoid

Filing the Confirmation Statement CS01 accurately is essential to ensure compliance and avoid penalties. Here are some common mistakes to watch out for.

Inaccurate Information

Ensure that all the information provided in the CS01 form is accurate and up-to-date. Incorrect details about directors, shareholders, or PSCs can lead to non-compliance and potential penalties.

Missing Deadlines

It’s important to keep track of the filing deadline and ensure the CS01 form is submitted on time. Set reminders and establish a process to gather and verify the required information well before the deadline.

Omitting PSC Information

Failure to include accurate information about People with Significant Control (PSC) can result in non-compliance. Make sure to identify and provide details about all PSCs in your company.

Incorrect Shareholding Structure

Ensure that the shareholding structure information is accurate, including the names of shareholders and the number and class of shares they hold. Any changes in shareholding must be reported in the CS01 form.
