What it is
The confirmation statement (form CS01) is an annual check that the information the registrar holds about your company is correct: registered office, officers, people with significant control, share capital, shareholders and SIC codes. It replaced the annual return in June 2016. Since 2024 it also carries a statement that the company's future activities will be lawful, and a registered email address.
When it's due
Your review period is 12 months, starting on the day of incorporation (then the day after the last statement date). You have 14 days after the review period ends to file. A company formed on 15 October 2026 must file by 28 October 2027. Filing early is allowed and resets the review period, which is how you change SIC codes mid-year.
What it costs
The annual fee is £34 online (£62 on paper) and is paid once per 12-month period however many statements you file in it.
What if nothing has changed?
You still file — the statement confirms the record is correct. It takes a few minutes on the the registrar's online filing service with your authentication code.
Consequences of missing it
There is no automatic fine, unlike accounts, but it is a criminal offence for the company and its directors, and the registrar will begin compulsory strike off after reminders go unanswered. Being struck off means the company ceases to exist and its assets pass to the Crown.
Common questions
When is the confirmation statement due?
At least once every 12 months, within 14 days of the end of your review period. The first review period ends on the anniversary of incorporation.
How much does it cost?
£34 online (fee as published by the registrar at time of writing).
What if I file nothing?
The company and its officers commit an offence and the registrar may start striking the company off.
