Filing a Confirmation Statement (CS01) with Companies House is a legal requirement for all UK companies. It keeps your company’s public record accurate and up to date. Missing this filing can lead to penalties or even the company being struck off the register. This post explains what a Confirmation Statement is, why it matters, and how to file it correctly.
What is a Confirmation Statement?
A Confirmation Statement is a snapshot of key company information at a specific date. It replaces the old Annual Return and must be filed at least once every 12 months. The statement confirms details such as:
Company registered address
Details of directors and company secretary
Shareholders and share capital
People with significant control (PSC)
The purpose is to ensure Companies House has the latest information about your company. This helps maintain transparency and allows the public, investors, and other stakeholders to access accurate company data.
Why Filing the Confirmation Statement Matters
Filing the Confirmation Statement on time is a legal obligation. Companies House uses this information to update the public register. If you miss the deadline, the company risks:
Receiving a late filing penalty
Being struck off the Companies House register
Losing good standing with banks and suppliers
For example, if a company changes its registered address or appoints a new director, failing to update this information can cause confusion or legal issues. Keeping the record current protects your company’s reputation and compliance status.
When and How to File the Confirmation Statement
You must file the Confirmation Statement within 14 days of the anniversary of your company’s incorporation or the date of the last statement. Companies House sends a reminder, but it’s best to track the deadline yourself.
Steps to file the CS01

Collect details about your company’s registered office, directors, shareholders, and PSCs.

Common Mistakes to Avoid
Filing a Confirmation Statement may seem straightforward, but errors can cause delays or penalties. Watch out for these common mistakes:
Missing the deadline
Mark your calendar and set reminders well before the due date.
Incorrect or outdated information
Double-check all details, especially addresses and director names.
Not including all shareholders or PSCs
Ensure you list everyone with significant control or shareholding.
Using the wrong company authentication code
If you lose your code, request a new one from Companies House.
Paying the wrong fee
Online filing is cheaper and quicker, so avoid postal submissions unless necessary.
What Happens After You File
Once Companies House receives your Confirmation Statement, they update the public register. The updated information becomes available to anyone searching the company’s details.
If there are errors or missing information, Companies House may contact you for clarification. Keeping your company’s records accurate helps avoid complications with banks, investors, or legal matters.
