How to File a Confirmation Statement Online (UK 2026/27)
Every UK limited company must file a confirmation statement at least once a year. Here is how to review the register, complete identity checks and file online for £50.
Quick answers
How do I file a confirmation statement online?
Review the register and complete any separate updates first. Use the Companies House confirmation statement service with the company authentication code and required director personal codes. Pay £50 if due for the payment period, submit and check acceptance.
How much does it cost?
The first confirmation statement in a 12-month payment period costs £50 online or through software, or £110 on paper. Further statements in that payment period do not attract another confirmation-statement fee.
The confirmation statement (CS01) is the annual confirmation that the information Companies House holds about a company is up to date. It is separate from annual accounts and the Corporation Tax return.
When it is due
You must file at least one confirmation statement every 12 months. The review period ends 12 months after incorporation or the confirmation date on the previous statement, and you then have 14 days to file. Companies House can impose a financial penalty of up to £5,000 and may strike the company off the register if the statement is not filed.
You may file early. Doing so starts the next review period on the day after the new confirmation date.
Cost
- £50 for the first digital confirmation statement in each 12-month payment period.
- £110 for a paper CS01.
The payment period is separate from the review period. Once the annual fee has been paid, further confirmation statements in that payment period do not attract another confirmation-statement fee.
Check and update the register first
Before filing, check the public register. Changes to directors and the company secretary, people with significant control (PSCs), the registered office, and an existing registered email address use their separate Companies House processes and should be completed before the statement.
The confirmation statement can include changes to SIC codes, statement of capital, trading status of shares, PSC reporting exemption, and shareholder information. It can also provide a registered email address if the company has not supplied one before.
Director identity verification
All current directors must verify their identity. The filing must include the 11-character Companies House personal code for each director and the required verification statement. Companies House will not accept the confirmation statement until every current director has completed identity verification.
Treat personal codes and the company authentication code as secrets. Only share them with a trusted person who is authorised to file for the company.
File online
- Open the Companies House confirmation statement service.
- Sign in and enter the company number and company authentication code.
- Check that prerequisite changes have already reached the register.
- Enter each current director's personal code when requested.
- Confirm the lawful-purpose and up-to-date-information statements.
- Pay the £50 annual fee if this is the first statement in the payment period, then submit.
- Keep the acknowledgement and check the filing history for acceptance.
Final checks and evidence
Check the company number, review date, shareholder information and the statements you are confirming. The confirmation statement cannot replace a separate director, PSC or address-change filing. If an earlier change has not reached the register, resolve it before confirming that the information is current.
Keep the acknowledgement and check the filing history for acceptance. If payment succeeds but the submission outcome is unclear, check status before paying or filing again. A saved draft is not a filed statement.
Review period versus payment period
Filing early starts a new review period, but it does not restart the separate fee payment period. For example, if you file another statement within a payment period whose annual fee has already been paid, there is no further confirmation-statement fee for that statement. Check the dates shown by Companies House rather than assuming every submission needs another payment.
Accounts and Corporation Tax have their own deadlines. Use the company accounts checklist and CT600 checklist for those obligations.
How Unfiled helps today
