Definition
A confirmation statement (form CS01) is the filing in which a company confirms that the information Companies House holds about it is correct, such as its officers, registered office, SIC code, shareholders and people with significant control. Every company, including dormant ones, must file one at least once every 12 months, within 14 days of the end of its review period. The online fee is £50.
When it is due and what it costs
The first review period ends 12 months after incorporation; later ones end 12 months after the date of the last statement. The fee is £50 online or £110 on paper, charged once in each 12-month payment period. Review periods are covered in more depth in confirmation statements explained.
What you confirm
Changes to directors, the secretary, people with significant control, the registered office and the registered email address must be filed before the statement. The statement itself can update the SIC code, statement of capital and shareholder details, and confirms the company’s intended future activities are lawful. Companies House will not accept it until every director has verified their identity.
Confirmation statement vs annual accounts
The confirmation statement confirms register details only. Annual accounts report the company’s finances and have a separate deadline.
