From 18 November 2025, all company directors and people with significant control (PSCs) will be legally required to verify their identity under the Economic Crime and Corporate Transparency Act 2023. This requirement is part of wider reforms to help prevent the misuse of UK companies.

Although not a deadline, more a “start-line” all returns to be filed after the above date will require this personal code to be submitted for all registered directors.

To do this start here Verify your identity for Companies House – GOV.UK

Once you have done this you will receive a personal code which you should keep secure, until such times as you may need that to submit accounts and returns to Registrar Of Companies
