What it is (and isn't)
The confirmation statement — form CS01 — is your annual confirmation to Companies House that the public record of your company is still correct. It is not your accounts, and it contains no financial performance at all. You're checking a snapshot, not reporting a year.
What the statement confirms:
- Registered office address and email
- Directors and company secretary
- People with significant control (PSCs)
- SIC codes — what the company actually does
- The statement of capital and shareholders
When it's due
Once every 12 months. Your review period runs for 12 months from incorporation, or from the date of your last statement, and you then have 14 days after it ends to file. You can file early — the moment you do, the next 12-month clock starts from that date.
The fee
£50 to file online, £110 on paper (2026). It's a flat annual fee and has nothing to do with your accounts or Corporation Tax — a separate filing, on a separate clock, with a separate cost.
Why missing it is worse than a fine
This one is criminal, not just costly
Because it carries no numbers and only a small fee, the confirmation statement is the filing directors most often forget — which is exactly backwards, given it's the one that can dissolve the company.
