Companies House

The confirmation statement, explained

The filing with no numbers in it — and the one whose absence can dissolve your company.

5 min readUpdated 13 July 2026

The short version

What it is
Form CS01 — confirms your registered details are current. Not your accounts, not a tax return.
When
Every 12 months; 14 days after the review period ends to file. File early and the clock resets.
Fee
£50 online, £110 on paper (from 1 February 2026).
If you miss it
A criminal offence to miss, and grounds for strike-off — more serious than a late-accounts penalty.

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

Late accounts get you a civil penalty. Failing to file a confirmation statement is a criminal offence by the company and its officers, and it's grounds for Companies House to strike the company off the register entirely. The stakes are higher than the £50 fee suggests.

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.

Common questions

What is a confirmation statement?

It's an annual filing (form CS01) that confirms the information Companies House holds about your company is still correct: registered office, directors, people with significant control, SIC codes and the statement of capital. You're confirming a snapshot, not sending new accounts.

How often do I file a confirmation statement?

Once every 12 months. Your 'review period' runs for 12 months from incorporation, or from your last statement, and you have 14 days after it ends to file. You can file early — filing resets the next 12-month clock.

How much is a confirmation statement?

£50 to file online (£110 on paper) since 1 February 2026. It's an annual fee, separate from anything to do with your accounts or Corporation Tax.

What happens if I don't file it?

Not filing is a criminal offence by the company and its officers, and Companies House can strike the company off the register. That's a harder consequence than the civil penalty for late accounts — which is exactly why it shouldn't be the filing you forget.
