What is confirmed in CS01?
Directors, shareholders and relevant capital structure, persons with significant control where the rules apply, registered office, SIC Codes, and other fields the form requires at filing time.

Confirmation Statement | Annual CS01 Filing
An annual filing with Companies House confirming that the company data shown on the register is still correct or updating it — entirely different from a Corporation Tax return.

Due-date schedule and how we track it
Every company has a due date linked to its incorporation or last statement. Late filing opens escalating penalties and can lead to action against the company’s continued presence on the register.

- Quick review of data shown on the register
- Prepare and file CS01
- Coordinate payment of government fees due for the statement when agreed

CS01 and annual accounts
Two separate paths. You may be required to file CS01 and accounts (full or Dormant) in different windows. Completing one does not close the other file.
FAQ about this service
Nothing changed this year — do I still file?
Yes. The statement is required even with “no change”; it is an official confirmation of continuity.
Can CS01 be filed early?
There are rules for early filing in certain cases. We choose what fits your company’s date so you do not confuse the next year’s cycle.
I forgot the deadline and received a penalty — can you help?
We file the late statement and guide you on dealing with the penalty according to your position. Acting quickly reduces how far the problem escalates.
