What Is an Annual Confirmation Statement?

File Confirmation Statement

If you operate a limited company in the UK, you are legally required to keep your company information accurate and up to date with Companies House. One of the most important compliance filings to do this is called the Annual Confirmation Statement.

The Annual Confirmation Statement, officially known as Form CS01, is a document submitted to Companies House to confirm that the company details on record are accurate. It replaced the older Annual Return in 2016 but serves a similar purpose.

You must file this document at least once a year, even if your company’s information has not changed. Filing the confirmation statement shows that your company is still active and operating legally.

Companies House uses this filing to maintain transparency in the public register. The Confirmation Statement confirms the basic facts about your company including:

This filing ensures that anyone checking your company’s details — including clients, banks, investors, and regulators — has access to current and accurate information.

The confirmation statement is due once every 12 months. Your first filing is due within 12 months of incorporation, and after that, every 12 months following the last statement’s confirmation date.

You have 14 days from the due date to submit it. While it is an annual requirement, you can also file an updated confirmation statement any time during the year if company details change.

The Annual Confirmation Statement includes:

If any of this information has changed since your last statement, you must update it before or at the time of filing the confirmation statement.

Failing to submit your confirmation statement on time can result in serious consequences:

There is no financial penalty for late filing of the confirmation statement, but the risk of your company being removed from the register makes it critical to file on time.

Online filing is strongly recommended for speed, accuracy, and instant confirmation of submission.

To file online, you will need your company number and authentication code (a 6-character security code provided by Companies House).

The Annual Confirmation Statement is a simple but essential part of managing a UK limited company. It helps Companies House maintain accurate public records and ensures that your company stays compliant and visible to the public, potential partners, and investors.

Remember to check and update your records each year, and don’t ignore the filing deadline. A few minutes of effort can help you avoid unnecessary risks and show that your company is actively and responsibly managed.
