You have 14 days after the end of your review period to file. The review period lasts 12 months. For a new company it starts on the day it was incorporated; after that, it starts the day after the date on your last statement.
Example: a company incorporated on 18 May 2026 has a first statement date of 17 May 2027 and must file by 31 May 2027.
What the confirmation statement is
Every company has to file a confirmation statement with Companies House at least once a year, including dormant companies and companies that do not trade. It confirms that the information Companies House holds about the company is up to date. You have to file it even if nothing has changed, and in it you also state that the company’s intended future activities are lawful (GOV.UK guidance).
When it is due
Your review period ends 12 months after:
- the date the company was incorporated, for the first statement, or
- the confirmation date on your last statement, for every statement after that.
You can file up to 14 days after the review period ends. Your company’s page on the Companies House register shows the next statement date and the date it is due by, and Companies House can send you email reminders.
To work your dates out from the rules, use the deadline calculator. If the register shows a different date, the register is right.
Filing early
You do not have to wait for the review period to end. If you file early, you choose a new confirmation date, and your next review period starts the day after it. Your next statement is then due 12 months and 14 days after the new date, not the old one.
The fee
It costs £50 to file online or through software, and £110 to file the paper form CS01 by post (Companies House fees).
You pay once in each 12-month payment period. The payment period is separate from the review period: it runs from the date of incorporation, and you cannot change it. If you file a second statement in the same payment period, there is no second fee.
What to update before you file
Before you confirm that your records are up to date, you must tell Companies House about any changes to the company’s:
- directors and secretary
- people with significant control (PSCs)
- registered office address
- registered email address
If the company has not yet given Companies House a registered email address, you must provide one in the statement. It is used to contact the company and is not shown on the public register.
The statement itself has a section for other changes: the SIC code that describes what the company does, the statement of capital, the trading status of shares, an exemption from giving PSC information, and shareholder information.
Identity verification for directors
Every director must verify their identity before the company files its next confirmation statement. The statement asks for each director’s Companies House personal code and a tick to confirm that each one is verified. Companies House will not accept the statement until every director has verified, so one unverified director holds up the whole filing.
People with significant control verify too, but they give their code separately, in their own 14-day window. The identity verification guide explains who needs to do what, and GOV.UK sets out the dates by role.
If you miss it
Companies House says it may issue a financial penalty, that you can be fined up to £5,000, and that the company may be struck off the register (GOV.UK guidance). If you have missed the date, file as soon as you can.
