Confirmation Statement Deadline Explained

One of the most common compliance mistakes UK business owners make is missing their confirmation statement deadline.

Many directors don’t realise that failing to file a confirmation statement on time can lead to serious consequences — including fines, compliance warnings, and even company strike-off.

In this guide, we’ll explain:

• What a confirmation statement deadline is
• When your CS01 is due
• How the review period works
• What happens if you miss the deadline
• How to avoid penalties and stay compliant

What Is a Confirmation Statement Deadline?

A confirmation statement deadline is the date by which your company must submit its annual CS01 filing to Companies House.

Every UK limited company is legally required to file a confirmation statement at least once every 12 months.

The purpose of the filing is to confirm that your company information is accurate and up to date.

This includes:

• Directors
• Shareholders
• Registered office address
• SIC codes
• People with Significant Control (PSC)
• Share capital details

Even if nothing has changed in your business, you must still file your confirmation statement.

How Does the Confirmation Statement Review Period Work?

Your confirmation statement operates on a 12‑month review period.

This review period usually starts:

• On the date your company was incorporated, or
• The date your last confirmation statement was filed

At the end of the review period, you have 14 days to submit your CS01.

Example of a Confirmation Statement Deadline

Let’s say your company was incorporated on:

-10 May 2025

Your review period would typically end on:

– 9 May 2026

You would then have 14 days to file your confirmation statement.

– Final filing deadline: 23 May 2026

Missing this deadline could trigger compliance action from Companies House.

How to Check Your Confirmation Statement Deadline

You can check your confirmation statement due date by:

• Logging into your Companies House account
• Searching your company on the Companies House register
• Reviewing previous filing confirmation emails

Many business owners forget their deadline because they only file once per year.

This is one reason why reminders and filing services are increasingly popular.

What Happens If You Miss the Confirmation Statement Deadline?

Missing your confirmation statement deadline can create serious problems for your business.

Companies House may:

• Issue warning notices
• Mark your company as non-compliant
• Begin strike-off procedures
• Remove your company from the register

If your company is struck off, the consequences can include:

• Frozen business bank accounts
• Loss of contracts
• Damage to business credibility
• Legal issues for directors

It’s a small filing — but missing it can create major disruption.

How Much Does It Cost to File a Confirmation Statement?

Companies House currently charges a £50 filing fee for submitting a confirmation statement.

This fee applies every time you file your CS01.

However, some filing services now cover the fee on behalf of business owners.

Common Reasons Business Owners Miss Their Deadline

They Forget the Date

Because confirmation statements are only filed once per year, many directors simply forget when they are due.

They Don’t Understand the Process

Many first-time founders confuse confirmation statements with annual accounts or tax filings.

They Delay Filing Until the Last Minute

Waiting until the deadline increases the risk of mistakes and missed submissions.

Authentication Code Problems

Some companies cannot access the filing system because they have lost their Companies House authentication code.

How to Avoid Missing Your Confirmation Statement Deadline

1. Set Calendar Reminders

Create reminders several weeks before your filing deadline.

2. Keep Company Records Updated

Updating company information regularly makes filing easier.

3. Don’t Leave It Until the Last Day

Submitting early reduces stress and lowers the risk of errors.

4. Use a Filing Service

Many business owners use filing services to:

• Receive reminders
• Avoid mistakes
• Stay compliant automatically
• Save time on admin

Can You File a Confirmation Statement Early?

Yes.

You can file your confirmation statement before the end of your review period.

In many cases, filing early is recommended because it:

• Reduces stress
• Helps avoid missed deadlines
• Gives time to correct mistakes if needed

Does Every Company Need to File a Confirmation Statement?

Yes.

All UK limited companies must file confirmation statements, including:

• Dormant companies
• Small businesses
• Startups
• Limited by shares companies
• Limited by guarantee companies

Even if your company has not traded, you still need to file.

Final Thoughts

Your confirmation statement deadline is one of the most important compliance dates for your business.

Although the filing itself is relatively simple, missing the deadline can create unnecessary risks, penalties, and stress.

The easiest approach is to stay ahead of your deadline and ensure your company records remain accurate and compliant.
