What Is a Confirmation Statement (CS01) and Why Is It Important?
A Confirmation Statement, also known as CS01, is a legal requirement for all UK limited companies. It confirms that the information held by Companies House about your company is accurate and up to date.
The CS01 includes details such as registered office address, directors, shareholders, share capital, and people with significant control. It must be filed at least once every 12 months, even if no changes have occurred.
Failing to file a Confirmation Statement can lead to penalties and, in serious cases, company strike-off. Many directors overlook this obligation because it does not involve financial figures, but it is just as important as annual accounts.
Filing can be done online or by post, depending on the company’s situation. Accuracy is essential, as incorrect information becomes part of the public record.
