From 18 November 2025, the Economic Crime and Corporate Transparency Act 2023 will make identity verification (IDV) mandatory for company directors, LLP members, and persons with significant control (PSCs). The measure aims to increase transparency, improve data accuracy at Companies House, and reduce the misuse of corporate structures for unlawful purposes.
In this newsletter, we discuss who must verify their identity, how the process will work, and what steps businesses should take to prepare.
Why are identity checks being introduced?
For years, Companies House records have relied largely on self-reported data. The new IDV regime represents a major shift toward verified company information. Every individual taking on a key role must now prove who they are, helping to prevent fraudulent appointments and protect businesses that depend on reliable corporate data.
Who must verify and when
The requirement applies to all directors and designated LLP members of UK entities, whether the individuals are based in the UK or abroad. Existing officeholders will have to complete verification at designated times within the 12 months from 18 November 2025, while anyone appointed on or after that date must verify before taking office.
PSCs must also complete verification within set timeframes. For UK branches of overseas companies, directors of the overseas company are caught by the same rules. Failure to comply can lead to criminal penalties and restrictions on acting in company roles. (For more details, please see here.)
How verification will work
Verification will be carried out in one of three ways:
- Directly through Companies House using the GOV.UK One Login system, which guides individuals through an online check using a valid passport, driving licence, or biometric residence permit.
- At participating Post Office branches, where documents can be verified in person.
- Through an Authorised Corporate Service Provider (ACSP) such as 3CS, which can manage the process on your behalf to ensure accuracy and avoid delays.
Once verified, individuals will receive a unique personal code confirming approval by Companies House. This code must be provided whenever they are linked to a company record or file a document. Filings without a valid code may be rejected, so completing verification early will be essential.
Preparing for implementation
Companies should start preparing by identifying who needs to verify, ensuring passport or ID documents are current, and planning how verification will be managed. Firms with upcoming confirmation statement deadlines soon after 18 November 2025 should act quickly, as unverified directors could block filings. Using an ACSP can simplify the process and reduce the risk of administrative errors.
