How to File a Confirmation Statement in the UK

Filing a confirmation statement is a legal requirement for every UK limited company. Whether you run a small business, startup, or dormant company, you must submit a confirmation statement (CS01) to Companies House at least once every 12 months.

Many business owners leave it until the last minute, misunderstand the process, or don’t realise missing the deadline can put their company at risk.

In this guide, we’ll explain:

• What a confirmation statement is
• When you need to file it
• What information you need

What Is a Confirmation Statement (CS01)?

A confirmation statement (CS01) is an annual filing submitted to Companies House to confirm that your company information is accurate and up to date.

The confirmation statement includes details such as:

• Company registered office address
• Directors and People with Significant Control (PSC)
• Shareholders and share capital
• SIC codes (business activity)
• Trading status of company shares

It is not the same as filing annual accounts or paying corporation tax.

Every UK limited company must file a confirmation statement, even if no company details have changed.

When Do You Need to File a Confirmation Statement?

You must file your confirmation statement at least once every 12 months.

Your filing deadline is based on your company’s review period, which usually starts:

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

You must submit your CS01 within 14 days after the end of the review period.

Failing to file on time can lead to:

• Financial penalties
• Compliance warnings
• Your company being struck off the Companies House register
