Confirmation statement deadline (UK)

Every UK limited company and LLP must file a confirmation statement at least once every 12 months. The filing window is 14 days from the company's confirmation date — and Companies House only sends one reminder, on the day it's already due.

What is this filing?

A confirmation statement (form CS01) confirms that the information Companies House holds about a company — registered office, directors, shareholders, SIC codes, PSCs — is accurate as of the confirmation date. It is not an accounting filing. The £34 online filing fee is payable each year.

When is it due?

The confirmation date is initially the company's incorporation anniversary; thereafter it rolls forward 12 months from the previous confirmation date. The filing deadline is 14 days after the confirmation date. Filing early is allowed and rolls the next confirmation date forward.

What's the penalty for missing it?

Missing the confirmation-statement deadline does not trigger an automatic monetary penalty in the same way late accounts do. However, persistent failure to file can — and frequently does — result in Companies House initiating strike-off proceedings against the company. Directors who fail to file may also be prosecuted personally.

How PenaltyProof helps

PenaltyProof reads the public Companies House API once a day for every company on your client list and emails you 30, 14, and 7 days before each confirmation-statement deadline (paid plans) — plus on the morning it's due. One signup covers your full client list; no per-company registration like the free CH email reminders.

Frequently asked questions

Can I file early?

Yes. Filing before the confirmation date is allowed and resets the 12-month clock — the next confirmation date becomes 12 months from the new filing date, not from the old confirmation date.

What if the company has no changes since last year?

You still have to file. The confirmation statement confirms accuracy — even when nothing has changed. There's a tick-box on form CS01 to mark 'no changes'.

Does PenaltyProof file the statement for me?

No. PenaltyProof only monitors and alerts. Filing happens on the Companies House WebFiling service or via your practice management software.
