In 2025, one of the biggest changes in UK company law will take effect, Companies House identity verification. Every company director, person with significant control (PSC), and authorised agent will soon need to prove their identity before they can set up, manage, or file information for a company.
This new requirement isn’t just another admin step. It’s part of a major government effort to make the UK’s business register more transparent, accurate, and trustworthy. By confirming who’s really behind every company, Companies House aims to prevent fraud and strengthen confidence in the corporate system.
Whether you’re a director, shareholder, or business owner abroad planning to incorporate in the UK, understanding how to complete this verification early will save you time, stress, and possible penalties later.
Let’s break down exactly what’s changing, who needs to act, and how you can verify your identity using either the GOV.UK One Login or through an authorised corporate service provider (ACSP).
From 18 November 2025, Companies House will begin requiring all company directors, people with significant control (PSCs), and authorised agents to verify their identity before they can act on behalf of a UK company.
This change is part of the Economic Crime and Corporate Transparency Act 2023, introduced to improve accuracy on the Companies House register and reduce fraudulent activity.
In simple terms, it means every person involved in managing, owning, or registering a company must prove they are who they claim to be before Companies House accepts filings from them.
The goal is straightforward: create a transparent, trustworthy register where fake identities or shell companies cannot hide behind false information.

The new requirement for identity verification is a crucial change driven by recent UK legislation to combat financial crime. Understanding the timing and the purpose is key to ensuring your company remains compliant.
The mandatory requirement for Companies House identity verification is set to begin on 18 November 2025.
From this date forward, all individuals involved in managing or registering a UK company must be verified. While this is the launch date, the deadline for existing directors and PSCs is typically tied to your company’s next Confirmation Statement after the launch date, meaning the requirement will phase in over the following 12 months.
This is not just another administrative hurdle. The change is part of the Economic Crime and Corporate Transparency Act 2023 (ECCTA) and serves two primary goals:

Identity verification applies to several groups connected to UK companies. Each individual who holds a role below will need to complete the verification process through an approved method:
This process ensures all key individuals linked to UK companies can be verified through a secure digital identity system.
There are two main routes you can take to complete the mandatory identity verification:
Companies House uses GOV.UK One Login, a secure government system for identity verification. You must verify your identity before forming a company or filing documents.
The second route is to use an Authorised Corporate Service Provider (ACSP), such as 121CompanyFormation.co.uk. This is often the preferred method for individuals who want an efficient, hands-off solution.
ACSPs are legally registered agents (e.g., company formation agents, accountants, solicitors) who are supervised under strict Anti-Money Laundering (AML) regulations.
The rollout begins in November 2025. From that point onward:
Companies that fail to ensure all directors are verified may face restrictions or compliance penalties.
Ignoring the new verification rules can have serious consequences. If a director or PSC fails to verify:
Directors are advised to act early and confirm their identity well before the enforcement date to avoid operational disruptions.
While the verification system is not fully live yet, every UK company should begin preparing now. Here’s what you can do to stay ahead:
Make sure your registered information on the Companies House register is accurate names, dates of birth, and service addresses should match your official ID documents.
