Identity verification requirements at Companies House became a legal requirement for directors and people with significant control (PSCs) from 18 November 2025. This date marked the start of a 12-month transition period for identity verification. 

Companies House is introducing the new requirements on a phased basis and affected individuals are being contacted directly with guidance on what action is required and the relevant deadlines. It is estimated that between 6 and 7 million individuals will need to complete identity verification by November 2026.

Verification is generally a one-time process and can be completed either directly through Companies House using GOV.UK One Login or through an Authorised Corporate Service Provider (ACSP), such as an accountant or solicitor.

Most individuals will be able to verify their identity online using photo identification documents such as a passport, UK driving licence or biometric residence permit. Alternative methods are also available, including in-person verification at selected Post Office branches or by using information linked to a UK bank account and National Insurance number.

Individuals who are unable to use the standard online or in-person routes may appoint an ACSP to verify their identity on their behalf. The provider must be registered with Companies House and supervised for anti-money laundering purposes.

Failure to comply with the new requirements could result in restrictions on company filings and penalties.
