Important Companies House Identity Verification Changes from 18 November 2025

Big changes are coming from Companies House this month that all company directors and people with significant control (PSCs) need to know about.

From 18 November 2025, a new legal requirement comes into effect under the Economic Crime and Corporate Transparency Act 2023. This legislation aims to make UK companies more transparent, tackle economic crime, and strengthen the integrity of business records.

What’s Changing
All company directors and PSCs must now verify their identity with Companies House to prove who they are. Once your identity has been verified, you’ll be issued a Personal Code by Companies House.This personal code will be required for any updates or changes to your personal details on the public register. It won’t affect the filing of financial accounts for now, but it forms part of the government’s wider programme to improve digital security and verification across business systems.

How to Verify Your Identity
There are three ways to complete your verification and obtain your Companies House Personal Code:

•  Online via GOV.UK One Login – You can verify your identity digitally if you have the necessary identification documents.
•  In person at selected Post Offices – You’ll need to check via GOV.UK first to confirm if you can use this method.
• Through an Authorised Corporate Service Provider (ACSP) – This includes registered agents such as accountants or solicitors who are authorised by
• Companies House to complete verification on your behalf.
