UK Confirmation Statement 2026 — What LTD Owners Must File and When
What Is the Confirmation Statement?
Every UK Limited Company must file a Confirmation Statement (form CS01) at least once every 12 months. This is a legal requirement under the Companies Act 2006, and failing to file can result in your company being struck off the Companies House register.
The Confirmation Statement confirms that the information Companies House holds about your company is accurate and up to date — including directors, shareholders, registered office address, SIC codes, and statement of capital.
What Information Must Be Confirmed?
- Registered office address — the official address of your company
- Directors — full names, date of birth, nationality, occupation, service address
- Shareholders (members) — names and number of shares held
- Statement of capital — total number of shares, their aggregate nominal value
- SIC codes — Standard Industrial Classification codes describing your business activities
- People with Significant Control (PSC) — anyone who owns more than 25% of shares or voting rights
When Must You File?
The first Confirmation Statement must be filed within 14 days of the anniversary of your company’s incorporation. Each subsequent statement is due within 14 days of the anniversary of the previous statement’s due date.
Example: If your company was incorporated on 1 January 2025, your first Confirmation Statement is due by 15 January 2026. If you filed it on 10 January 2026, the next one is due by 24 January 2027.
How to File
You can file your Confirmation Statement online through the Companies House WebFiling service or by post using form CS01. Online filing costs £34, while paper filing costs £62. Most companies file online — it is faster, cheaper, and the system pre-populates your existing data.
What If There Are Changes?
If any of the information has changed since your last filing (e.g., new director appointed, change of registered office), you must update these details before filing the Confirmation Statement. The Confirmation Statement itself only confirms the current state — it does not make changes.
Penalties for Late Filing
Companies House does not impose late filing penalties for Confirmation Statements in the same way HMRC does for accounts. However, failing to file can lead to your company being struck off the register. Directors may also face personal liability and prosecution. It is a criminal offence not to file.
