What is a confirmation statement?
A confirmation statement is a short annual filing that confirms the information Companies House holds about your company is accurate and up to date, rather than reporting anything new. It covers your registered office, directors, shareholders, statement of capital, SIC codes and people with significant control (PSC).
It replaced the old annual return in 2016 and is filed using form CS01. If nothing has changed since your last statement, you simply confirm that fact; if something has changed, the confirmation statement is where you tell Companies House.
How much does it cost to file a confirmation statement?
Our fee for confirmation statement filing is £49 + VAT, which covers checking your company's details, preparing the CS01 and submitting it on your behalf. On top of that there is the Companies House fee of £50 for digital filing from 1 February 2026, which we pass on at cost with no VAT and no markup. Any Companies House fee shown is charged at today's rate; if Companies House changes it, we charge the new fee separately.
There is no fee at all for filing a paper confirmation statement in some circumstances, but paper filing is slower and more error-prone, which is why almost every company files online.
When is my confirmation statement due?
Your confirmation statement is due within 14 days after the end of your review period. The review period runs for 12 months, starting either from the date your company was incorporated or from the date of your previous confirmation statement.
Companies House will send a reminder by email or post, but the legal responsibility to file on time sits with the company's directors, not with Companies House. We recommend setting your own reminder well ahead of the 14-day window.
What information do I need to file a confirmation statement?
You will need your company's registered office address, a list of current directors and their service addresses, your statement of capital if you have shares, details of your shareholders, your SIC (industry classification) codes, and up-to-date information on anyone with significant control (PSC) over the company.
If any of this has changed since your last filing, you should update it as part of the confirmation statement. We check each of these areas before we submit your statement so nothing is missed.
- Registered office address
- Director details and service addresses
- Statement of capital and shareholder information
- SIC codes describing your business activity
- People with significant control (PSC) register
Do dormant companies need to file a confirmation statement?
Yes. Dormant companies still need to file a confirmation statement every year, even though they are exempt from filing full accounts in the usual way. The confirmation statement is about keeping Companies House's public record accurate, not about whether your company is trading.
We regularly file confirmation statements for dormant companies alongside their simplified dormant accounts, so you can keep both filings up to date in one go.
Can an accountant file my confirmation statement for me?
Yes, an accountant can file your confirmation statement for you using your Companies House authentication code or by acting as your authorised agent. As ICAEW Chartered Accountants, we handle the whole process, from checking your details to submitting the CS01 and confirming it has been accepted.
This is particularly useful if you also want us to review whether your director, shareholder or SIC code information needs updating, since a confirmation statement is often the trigger for spotting out-of-date company records.
What happens if my confirmation statement is late or overdue?
There is no fixed financial penalty for filing a confirmation statement late, unlike accounts. However, failing to deliver a confirmation statement on time is a criminal offence under section 853L of the Companies Act 2006, and directors can be personally prosecuted or fined.
In practice, Companies House's main sanction is to begin the process of striking your company off the register, starting with a first Gazette notice if a confirmation statement is significantly overdue. If your company is struck off, its assets can pass to the Crown, so it's worth treating an overdue confirmation statement seriously and filing it as soon as possible.
