How to File a Confirmation Statement: Complete Guide
Learn how to file a Confirmation Statement, when it’s due, what details are included, and how to stay compliant with Companies House rules.

If you run a limited company in the UK, one of your most important legal duties is filing a Confirmation Statement with Companies House. This filing ensures that all company details are up to date and publicly available. Missing the deadline or submitting incorrect information can lead to penalties or even the company being struck off the register. This guide explains everything you need to know about filing a Confirmation Statement.
What Is a Confirmation Statement?
A Confirmation Statement (form CS01) is a yearly filing that confirms the details Companies House holds about your company are correct. Instead of resubmitting all the information, you simply confirm that it is accurate or update it if there are any changes.
When Do You Need to File?
-
The first Confirmation Statement is due 12 months after incorporation.
-
After that, a new one must be filed at least once every 12 months.
-
You have 14 days from the due date to file.
You can also file an updated Confirmation Statement earlier if company details change, such as shareholder information or PSCs (People with Significant Control).
What Information Does It Cover?
The Confirmation Statement includes key company details such as:
-
Registered office address
-
Directors and company secretary (if applicable)
-
Shareholders and share capital
-
Persons with Significant Control (PSC)
-
Standard Industrial Classification (SIC) codes
