Form CS01


What is Form CS01 and Why is It Important for UK Companies?

If you own or manage a company in the UK, filing a Confirmation Statement (Form CS01) is something you cannot afford to ignore. It’s a legal requirement enforced by Companies House, and failing to submit it on time could lead to penalties or even your company being struck off the register.


But what exactly is Form CS01? How does it work, and why is it important? This guide breaks down everything you need to know in simple terms, including the latest updates for 2024 and 2025.


What is a Confirmation Statement (CS01)?

A Confirmation Statement is an official document that all companies in the UK must file at least once a year with Companies House. Its main purpose is to confirm that the information held about your company is accurate and up to date.


Unlike other forms that record changes to your company’s structure, the CS01 simply confirms that your details are correct. Even if nothing has changed, you still need to file it every year.


Why is the Confirmation Statement Important?

Submitting your confirmation statement is more than just ticking a box for compliance. It plays a crucial role in maintaining transparency in the UK business environment. Here's why it's important:


  • Legal Requirement: All companies registered in the UK, including dormant and non-trading companies, must file a CS01 at least once a year.

  • Avoiding Penalties & Striking Off: If you fail to file on time, Companies House may issue financial penalties and can even strike off your company from the register.

  • Business Transparency: Keeping your company records updated ensures that shareholders, clients, and investors can trust your business.

  • Avoiding Fraud Risks: Outdated company records can be exploited for fraudulent activities, such as identity theft or company hijacking.


Who Needs to File Form CS01?

If you’re running a company in the UK, you probably need to file a confirmation statement. The requirement applies to:


  • Limited Companies (LTD)

  • Limited Liability Partnerships (LLPs)

  • Community Interest Companies (CICs)

  • Public Limited Companies (PLCs)

  • Dormant Companies (even if there’s no business activity)


Sole traders and general partnerships do not need to file a confirmation statement, as they are not registered with Companies House.


When Do You Need to File a Confirmation Statement?

Your company must file a confirmation statement at least once every 12 months. This 12-month period is called the Review Period.


How to Determine Your Review Period:

  • If your company is new, the first review period starts from the date of incorporation.

  • If your company has already filed a CS01 before, the review period starts from the date of the last filed statement.


At the end of your 12-month review period, you have 14 days to file your CS01.


Example: A company was incorporated on 1st January 2024. The review period runs until 31st December 2024. The company must file its CS01 by 14th January 2025.


New Updates for Confirmation Statement (Effective from March 2024)

As of 5th March 2024, the UK government introduced some new rules for the Confirmation Statement under the Economic Crime and Corporate Transparency Act. These updates aim to prevent fraud and enhance corporate transparency.


Key Changes You Need to Know:

  1. Declaration of Lawful Purpose:

    • Companies must now declare that their future activities will be lawful.

    • This is part of the UK government’s efforts to tackle fraud and illegal business activities.

  2. Mandatory Email Address:

    • Companies must provide a registered email address.

    • Companies House will use this email for official communication.

    • This email will not be made public but must be kept up to date.

  3. Stronger Enforcement Against Non-Compliance:

    • Companies House can now impose higher penalties on companies that fail to file their CS01 on time.

    • The process of striking off non-compliant companies has been made faster.


How Much Does It Cost to File a Confirmation Statement?

Filing your CS01 isn’t free, but the cost depends on how you submit it:

Filing Method

Cost

Online Filing (Recommended)

£34 per year

Paper Form Submission

£62 per year

The fee is only required once per 12-month payment period, regardless of how many times you file during that period.


Example: If a company’s payment period starts on 1st January 2024, and they file their CS01 on 30th September 2024, they pay the fee. But if they file another CS01 on 1st December 2024, they do not need to pay again.


However, if they file on 5th January 2025, they must pay the fee again because it falls into a new payment period.


How to File a Confirmation Statement (CS01)?

Filing your CS01 is easy and can be done in two ways:

  1. Online Filing (Recommended)

  2. Paper Form (CS01 Form Download)

    • Download Form CS01 from the Companies House website.

    • Fill in your company details manually.

    • Send the form via post along with the £62 fee.


📌 Important Note: Companies House is moving towards a fully digital system, so online filing is the faster and preferred method.


What Happens If You Don’t File a CS01?

Failing to file a confirmation statement on time can lead to serious consequences:

🚨 Penalties & Consequences:

  • Late Filing Penalty: Companies House may impose financial penalties.

  • Company Striking Off: If you ignore multiple reminders, your company could be removed from the Companies House register.

  • Director Liability: If a company is struck off, directors may still be held liable for any outstanding debts or legal issues.


The Confirmation Statement (CS01) is a mandatory annual filing requirement for UK companies. With new changes in 2024, including lawful activity declarations and mandatory email addresses, businesses must ensure they file correctly and on time.



Updating Company Details and Key Changes Before Filing Form CS01

In Part 1, we covered what Form CS01 – the Confirmation Statement is, why it’s important, and how to file it. Now, let’s dive into what updates must be made before submitting the confirmation statement, how to handle changes to your business, and real-life examples of companies that faced consequences for non-compliance.


What Must Be Updated Before Filing a Confirmation Statement?

Before you submit your confirmation statement, you need to make sure that all details registered with Companies House are correct and up to date. If there are any changes, some updates must be filed separately first before you can proceed with your CS01.


1. Key Changes That Must Be Reported Separately

Certain company details cannot be updated directly on the CS01 form. Instead, you must file separate forms before submitting your confirmation statement. These changes include:

Company Information

How to Report the Change?

Company Directors or Secretaries

File Form AP01 (appointment) or TM01 (termination)

People with Significant Control (PSC)

File PSC01 to PSC09 forms

Registered Office Address

File Form AD01

Registered Email Address (New Requirement from March 2024)

Update online via Companies House WebFiling

🔍 Example: If your company appoints a new director, you must first submit Form AP01 to update the record before filing your CS01.


2. Changes That Can Be Updated in the Confirmation Statement (CS01)

Some details can be updated directly within the confirmation statement when filing.


These include:

Standard Industrial Classification (SIC) Code

  • The SIC code identifies the type of business activity your company is involved in.

  • You can add, remove, or change your SIC code when filing your CS01.

Statement of Capital

  • If there are changes in shares or capital, you can update the share capital details in your CS01.

Trading Status of Shares

  • You must confirm if your shares are publicly traded.

Exemption from Keeping a PSC Register

  • If your company no longer qualifies for an exemption, this can be reported in the CS01.

Shareholder Information

  • If there have been changes to shareholders, such as new shareholders being added or existing ones leaving, you can update this directly in the confirmation statement.


🔍 Example: If your company changed its business activity from IT consulting to marketing services, you would need to update the SIC code in the CS01 form.


Step-by-Step Guide to Updating and Filing a Confirmation Statement

Now that you know what must be updated, here’s a step-by-step process for filing your confirmation statement correctly:


Step 1: Check Your Company Records

  • Review your details on the Companies House register.

  • Identify any necessary updates.


Step 2: Submit Any Required Updates Separately

  • If changes are required (e.g., director appointment), submit the relevant form before filing your CS01.


Step 3: File Your Confirmation Statement (CS01)


Step 4: Receive Confirmation from Companies House

  • After submission, Companies House will review and process your statement.

  • If accepted, your company details will be officially updated.


What Happens If You File Incorrect or Outdated Information?

🚨 Filing incorrect or outdated details can lead to serious problems, including:

  • Legal Consequences: Incorrect filings can result in penalties.

  • Company Strike-Off: Repeated non-compliance can lead to your business being removed from the register.

  • Difficulties in Business Operations: Incorrect details can affect banking, contracts, and investor confidence.


🔍 Case Study: A Business That Failed to Update Details


📌 Case: XYZ Ltd – Ignored Updates, Faced Strike-OffXYZ Ltd was a small IT consultancy firm. The company’s director resigned, but the new director failed to submit the required AP01 form. When the confirmation statement was filed, the Companies House records still listed the previous director.


Result:

  • Companies House flagged the company for incorrect filings.

  • XYZ Ltd was given 14 days to update its records.

  • The company ignored the warning, leading to a compulsory strike-off notice.


💡 Lesson: Always update key details separately before submitting your CS01 to avoid compliance issues.


Common Mistakes Businesses Make with Form CS01

Even experienced business owners sometimes make errors when filing their confirmation statement. Here are some of the most common mistakes and how to avoid them:

Common Mistake

How to Avoid It?

Missing the Filing Deadline

Set reminders to file before the 14-day deadline.

Not Updating Company Details Before Filing

Update directors, PSCs, and addresses before submitting the CS01.

Using the Wrong SIC Code

Check the official SIC code list before filing.

Filing with Outdated Shareholder Information

Always review and update shareholder records before submission.

Not Paying the Fee on Time

Ensure you pay the correct amount (£34 online, £62 paper).

New 2024 & 2025 Updates: What to Expect Next?


🔔 As of 2024, the UK government is tightening compliance rules. More updates could be introduced in 2025, including:


  1. More Digitalization:

    • Companies House is pushing for a fully online filing system, meaning paper forms may eventually be phased out.

  2. Tougher Penalties for Late Filing:

    • There may be an increase in penalties for businesses that repeatedly fail to submit CS01 on time.

  3. Greater Scrutiny on Business Activity:

    • The requirement to declare lawful activity may be expanded further to ensure businesses operate legally.


📌 Stay Updated: Always check the official Companies House website for the latest regulations.


Correcting Errors, Late Filings, and What Happens If Your Company is Struck Off

Now, in this final section, we’ll cover how to fix errors in a filed confirmation statement, what happens if you miss the deadline, and the consequences of being struck off the Companies House register.


How to Correct Mistakes in a Submitted Confirmation Statement

Sometimes, mistakes happen—even after you’ve submitted your CS01. Maybe you accidentally reported an incorrect Standard Industrial Classification (SIC) code, or perhaps a shareholder change wasn’t recorded properly.


The good news is that mistakes can be corrected, but you need to act fast.


1. How to File a Corrected Confirmation Statement (Form CS01 – RP04 Process)

If you’ve made an error on a submitted CS01, you need to file Form RP04 (Second Filing of a Confirmation Statement) to correct it.


🔍 Steps to Fix an Error in CS01:

  1. Download Form RP04 from the Companies House website.

  2. Provide the correct information (e.g., fixing incorrect SIC codes, shareholder changes, or missing data).

  3. Submit the corrected statement along with a copy of the original incorrect CS01.

  4. Send it to Companies House online or by post.


📝 Important Notes:

  • You do not need to pay the confirmation statement fee again when filing Form RP04.

  • The correction must only include the information that was incorrect—not an entirely new CS01.


🚨 Common Errors That Require Form RP04:

  • Wrong SIC code listed

  • Incorrect or missing shareholder information

  • Inaccurate statement of capital

  • Forgetting to include new People with Significant Control (PSC)


What Happens If You Miss the Confirmation Statement Deadline?

Filing deadlines are strict, and failing to submit your CS01 on time can cause serious problems for your company.


1. Understanding the 14-Day Deadline

Every company has 14 days from the end of its review period to file Form CS01.


Example: If your review period ends on 31st December 2024, you must file your confirmation statement by 14th January 2025.


2. Consequences of Late Filing

Missing the deadline doesn’t result in automatic penalties like a late tax return, but it does have serious consequences:


🔴 Warning Notices

  • Companies House will send reminders and warnings urging you to file your confirmation statement.

⚠️ Financial Penalties (If Ignored)

  • If you repeatedly file late, Companies House can impose financial penalties, although these are not automatic like tax fines.

Company Strike-Off (If Continuously Ignored)

  • If you fail to submit CS01 for a long period, Companies House may assume your company is no longer trading and begin the strike-off process.


What Happens If Your Company is Struck Off?

If a company continuously ignores filing requirements, Companies House can remove it from the register, meaning the company is dissolved and ceases to exist.


🚨 What Happens When a Company is Struck Off?

  1. Bank Accounts Are Frozen: Your company’s business bank accounts will be closed, and all funds will be transferred to the government (bona vacantia).

  2. Loss of Legal Protection: The company no longer legally exists, meaning it cannot trade, enter contracts, or own property.

  3. Directors May Face Personal Liability: If the company owes debts, directors may be personally liable for certain unpaid obligations.

  4. Reputation Damage: Being struck off affects your credibility, making it difficult to restart a business later.


Can a Struck-Off Company Be Restored?

Yes, but it’s a complex legal process. There are two ways to restore a company:

Restoration Method

Who Can Apply?

When to Use?

Administrative Restoration

Former directors or shareholders

If the company was struck off in the last 6 years due to failure to file CS01.

Court Order Restoration

Anyone with an interest in the company

If the company was struck off more than 6 years ago or for reasons beyond CS01 failures.

🔍 Steps to Restore a Company (Administrative Restoration):

  1. Complete Form RT01 and submit it to Companies House.

  2. Pay the restoration fee (£100).

  3. File any missing confirmation statements and accounts.


📌 Important:

  • The restoration process can take weeks or months, causing major business disruptions.


Avoiding Future Issues with Your Confirmation Statement

To ensure your company stays compliant and avoids penalties, here are some best practices:


Set Reminders

  • Use accounting software or a simple calendar reminder to track your CS01 deadline.

File Online for Faster Processing

  • Use Companies House WebFiling to file electronically—it's cheaper (£34) and processed faster.

Keep Your Company Records Updated Year-Round

  • Don’t wait until the CS01 deadline to update directors, shareholders, or PSCs.

Check the SIC Code Regularly

  • If your business changes its focus, make sure your SIC code reflects the correct industry.

If in Doubt, Seek Professional Advice

  • If your company has complex share structures or multiple directors, consult an accountant or company secretary to avoid mistakes.

🔹 Part 3: Correcting errors, late filings, company strike-offs, and restorations.


💡 The Bottom Line: Filing your confirmation statement (CS01) on time is not optional—it’s a legal requirement for all UK companies. With new 2024 and 2025 regulations, Companies House is tightening enforcement, so staying compliant is more important than ever.


To avoid legal trouble, file your CS01 accurately and on time—because running a business is tough enough without unnecessary penalties!



Different Parts of Form CS01

In the previous sections, we have explored Form CS01 – the Confirmation Statement, its importance, filing requirements, penalties for non-compliance, and how to correct errors. However, Form CS01 has several related parts and continuation pages that are used to update specific details about a company when filing a confirmation statement.


1. What is Form CS01 and Why Are There Multiple Parts?

Form CS01 is used to confirm that a company’s records at Companies House are up to date. However, if a company has undergone changes in certain aspects of its structure, some details must be updated using specific parts of Form CS01.


🔹 If no details have changed, companies simply file Form CS01 without any additional sections.

🔹 If there have been changes, companies must include the relevant CS01 parts (1 to 4) with their submission.


💡 Important Update: From 5 March 2024, a new version of Form CS01 must be used for companies filing their confirmation statement. The previous version of the form is only valid for confirmation dates between 30 June 2016 and 4 March 2024.


2. Breakdown of Form CS01 Parts 1 to 4

Companies House provides four additional sections that can be attached to Form CS01 when filing a confirmation statement. These sections are used to update information about:


  • Principal business activities (SIC code)

  • Statement of capital

  • Trading status of shares and PSC exemption

  • Shareholder information

CS01 Part

Purpose

When to Use It?

Updating the company’s principal business activities (SIC codes)

If the company has changed its main business activity.

Updating the statement of capital

If the company has issued new shares or changed its share structure.

Updating the trading status of shares and PSC exemption

If the company’s shares are now being traded on a market or it has gained/lost an exemption from keeping a PSC register.

Updating shareholder information

If there have been new shareholders, share transfers, or other changes.

🔍 Example: A company initially registered as an IT consultancy (SIC code 62020) but has now expanded into cybersecurity services (SIC code 62090). It must file CS01 Part 1 to update its business classification.


CS01 Part 1 – Updating Principal Business Activities (SIC Codes)

The Standard Industrial Classification (SIC) code represents a company’s main business activities. If a company has changed its primary business operations, it must update its SIC code in CS01 Part 1.


When to use it?

  • If the company has expanded or shifted its business focus.

  • If the originally listed SIC code is incorrect.

📌 Example:

  • A retail company that previously focused on clothing (SIC 47710) but has shifted to online retailing (SIC 47910) must update its SIC code using CS01 Part 1.


CS01 Part 2 – Updating the Statement of Capital

The statement of capital includes details about the company’s share structure, such as:

  • The total number of shares issued

  • The nominal value of shares

  • The class of shares (e.g., ordinary, preference shares)


When to use it?

  • If the company has issued new shares.

  • If the company has changed its share structure (e.g., introducing a new class of shares).


📌 Example: A startup initially had 1,000 ordinary shares worth £1 each but has issued 500 additional shares. The company must file CS01 Part 2 to update its capital structure.


CS01 Part 3 – Updating the Trading Status of Shares and PSC Exemption

This section is used to update:

  1. Whether company shares are now traded on a stock market.

  2. Changes in exemption status from maintaining a PSC register.


When to use it?

  • If the company’s shares have started or stopped trading on a public market (e.g., AIM, London Stock Exchange).

  • If the company was previously exempt from keeping a People with Significant Control (PSC) register but no longer qualifies for the exemption.


📌 Example: A private company that was not trading shares publicly has now listed on the Alternative Investment Market (AIM). It must update its trading status using CS01 Part 3.


CS01 Part 4 – Updating Shareholder Information

If a company has issued new shares, transferred shares, or had changes in ownership, it must submit CS01 Part 4 to update its shareholder records.


When to use it?

  • If a new shareholder has been added.

  • If an existing shareholder has sold or transferred their shares.

  • If a shareholder’s details (e.g., address) need updating.


📌 Example: A company that had two shareholders but now has a third investor acquiring shares must file CS01 Part 4.


3. Restoring a Company Using Form CS01

If a company has been struck off the Companies House register due to non-compliance (e.g., failure to file a confirmation statement), it may need to be restored.


Key Restoration Requirements:

  • The company must provide the confirmation date that was due before it was struck off.

  • If unsure of the correct date, Companies House should be contacted before submitting the CS01 form.


📌 Example: A company was struck off in June 2024 due to a missed confirmation statement. To be restored, it must file a paper Form CS01 with the correct confirmation date.


4. Continuation Pages for CS01

When filing Form CS01, companies sometimes need to include additional details, such as:

  • More than one SIC code.

  • A large number of shareholders.

  • A complex share capital structure.


In these cases, Companies House provides continuation pages to ensure all relevant information is submitted correctly.


When to use them?

  • If there isn’t enough space on the main form.

  • If additional details are required for accuracy.


Final Thoughts on Other Forms Related to CS01

🔹 Form CS01 is essential for confirming company records, but changes must be reported using the correct parts (1-4).

🔹 SIC code updates, share structure modifications, and shareholder changes all require specific CS01 attachments.

🔹 A struck-off company must submit Form CS01 with the correct confirmation date for restoration.


By ensuring that all relevant CS01 parts are filed correctly, companies can maintain compliance and avoid penalties from Companies House.

Other Forms Related to Form CS01


Other Forms Related to Form CS01

In the previous sections, we have explored Form CS01 – the Confirmation Statement, its importance, filing requirements, penalties for non-compliance, and how to correct errors. However, CS01 is not the only form related to company compliance in the UK.

Various other forms must be filed with Companies House depending on specific changes or events affecting a company. These forms help update critical information such as directors, shareholders, registered addresses, company structure, and people with significant control (PSC).


1. Forms for Updating Directors and Secretaries

A company’s directors and secretaries play a key role in governance and must be properly recorded with Companies House. If there are any changes to these roles, the following forms must be used:


If a company appoints a new director, Form AP01 must be filed.

  • Who needs to file it? The company, typically by the existing directors or the company secretary.

  • Deadline for filing: Must be submitted within 14 days of the appointment.

  • Why it’s important: If a director is appointed but not officially registered, they cannot legally act in their role.


📌 Example: If a company hires a new managing director on 1st March 2025, the AP01 form must be filed by 15th March 2025.


If a director leaves the company (either by resignation, removal, or death), the company must file Form TM01.

  • Who needs to file it? The company.

  • Deadline for filing: Within 14 days of the director’s termination.

  • Why it’s important: If a director is no longer active but their details remain on record, they may still be held legally responsible for the company’s actions.


📌 Example: A director resigns on 10th June 2025—the company must submit TM01 by 24th June 2025.


AP03 & TM02 – Appointment and Termination of a Company Secretary

  • AP03 is used to appoint a company secretary.

  • TM02 is used to remove a company secretary.

📌 Important Note:

  • Since April 2008, private limited companies (LTDs) are no longer required to have a company secretary, but if one is appointed or removed, Companies House must be notified.

  • Public Limited Companies (PLCs) are still required to have a secretary.


2. Forms for Updating Shareholders and Share Capital


When a company issues new shares, it must notify Companies House by submitting Form SH01.

  • Who needs to file it? The company.

  • Deadline for filing: Within one month of the share issue.

  • Why it’s important: Issuing shares increases the company’s share capital, and failure to report could result in incorrect company records and potential legal issues.


📌 Example: A company issues new shares to an investor on 5th May 2025—it must file SH01 by 5th June 2025.


If a company decides to reduce its share capital, it must submit Form SH02 to Companies House.

  • Why companies reduce share capital:

    • To return money to shareholders.

    • To eliminate unused shares.

    • To improve financial structure.

  • Legal requirement: The reduction must be approved by shareholders and supported by a solvency statement.


📌 Example: A company wants to reduce its share capital from £1 million to £500,000—it must submit Form SH02 along with supporting documents.


If a company buys back shares from shareholders, it must file Form SH03 to record the transaction.

  • Who needs to file it? The company.

  • Why it’s important: Buying back shares affects company ownership and share capital.


📌 Example: A business wants to buy back shares from an investor to give remaining shareholders more control. This transaction must be reported using Form SH03.


3. Forms for People with Significant Control (PSC)


Since 2016, all UK companies must keep records of their People with Significant Control (PSC). A PSC is anyone who:

  • Owns more than 25% of shares in a company.

  • Holds more than 25% of voting rights.

  • Has the right to appoint or remove directors.


📌 Forms to Report PSC Changes:

Form

Purpose

Adding a new PSC

Updating a PSC’s details

Removing a PSC

Used for various PSC-related changes, such as nature of control or legal entity updates.


🔍 Example: If an investor acquires 30% ownership of a company, the company must file PSC01 to report them as a Person with Significant Control.


4. Forms for Changing Registered Address and Company Details


  • Companies must file Form AD01 when they change their registered office address.

  • The new address must be within the same country (England, Wales, Scotland, or Northern Ireland).

  • Companies House must be notified within 14 days.


📌 Example: A company moves from Manchester to London—it must file AD01 to update its registered address.


If a company stores its statutory records at a location different from its registered office, it must notify Companies House using Form AD02.


5. Forms for Restoring a Struck-Off Company

If a company is struck off the register, it can apply for restoration using the following:

Form

Purpose

RT01

Administrative restoration if the company was struck off in the last 6 years.

Court Order Restoration

Required if administrative restoration is not applicable.

📌 Example: If a company was struck off for failing to file CS01, it can apply for restoration using RT01.


Key Takeaways:

CS01 is for confirming company details, but many changes require separate forms.

Director changes? Use AP01, AP03, TM01, or TM02.

Shareholder and capital changes? Use SH01, SH02, or SH03.

New investors with control? File PSC01 – PSC09.

Moving offices? File AD01.

Restoring a company? Use RT01.


By staying on top of these mandatory filings, businesses can avoid legal trouble, keep records accurate, and remain in good standing with Companies House. 🚀
