Every UK company, including dormant and non-trading companies, must file a confirmation statement with Companies House at least once every 12 months. It confirms that the information Companies House holds about the company is up to date.
It is not your annual accounts, and it is not your CT600. Missing it still creates real risk: Companies House may issue a financial penalty, and the company can be struck off if you ignore the duty.
Year-end readiness is wider than accounts alone. YearReady™ helps you keep the year-end pack moving early. Diary the confirmation statement beside your accounts deadline so one compliance job does not knock out the other.
When the confirmation statement is due
According to GOV.UK:
- You must review your records and file at least one confirmation statement every 12 months.
- The review period ends 12 months after your last confirmation statement date (or after incorporation for the first one).
- You can file up to 14 days after the review period has ended.
Check your confirmation date and filing deadline on the company information register, and consider Companies House email reminders.
What it costs
GOV.UK states it costs £50 to file a confirmation statement online, and £110 by post. Prefer online filing unless you have a reason not to.
What you are confirming
In plain terms, you are confirming company details such as officers, people with significant control, registered office, and related register information are correct for the period. Rules have tightened under economic crime reforms, including requirements such as a registered email address on statements from the dates GOV.UK specifies. If anything changed during the year, make sure Companies House already has the update, or update it as part of the process your software or accountant uses.
Late confirmation statements
GOV.UK warns that Companies House may issue a financial penalty and that the company may be struck off if you do not file. Separate guidance also notes you can be fined up to £5,000 in serious cases. Enforcement practice has been strengthening under the Economic Crime and Corporate Transparency Act. Do not treat "no automatic accounts-style ladder" as "safe to ignore".
If you receive a warning notice, file within the time it gives. Paying a penalty does not remove the duty to file.
Quick checklist
Find your confirmation statement date on the public company record.
Diary the deadline (review period end plus up to 14 days).
Check officers, PSC and registered office before you file.
File online for £50 unless post is required.
Keep accounts and confirmation statement on separate calendars.
