1. What is a UK Confirmation Statement (Form CS01)?
Under Section 853A of the Companies Act 2006, every UK company must deliver a Confirmation Statement (Form CS01) to Companies House at least once in every 12-month period.
The purpose of the Confirmation Statement is to verify that all statutory company records held on the public Companies House register are accurate and up to date.
2. Confirmation Statement vs Annual Tax Accounts
Many first-time overseas directors confuse the Confirmation Statement with annual financial accounts. They serve entirely distinct legal functions:
Corporate Governance: Confirms directors, shareholders, registered address, and PSC data. Submitted to Companies House. Contains NO financial figures.
Financial & Tax Reporting: Reports profit/loss, balance sheet, and Corporation Tax liabilities. Submitted to HMRC and Companies House.
3. What Information Must Be Verified on Form CS01?
When submitting Form CS01, you must review and confirm six core company metrics:
Mandatory Verification Checklist:
- Registered Office Address: Confirms physical London or UK office location.
- Directors & Officers Details: Service addresses and residential address privacy records.
- People with Significant Control (PSC): Beneficial owners holding > 25% shares or voting rights.
- Statement of Capital: Total number, class, and aggregate nominal value of issued shares.
- Shareholder Register: Current list of company shareholders.
- SIC Code: 5-digit Standard Industrial Classification code describing primary business activity.
