Since then, Companies House has released new deadlines and guidance. This update explains what has changed, who must act, and how businesses can prepare ahead of the November 2025 deadline.

What is UK Company Identity Verification?
UK company identity verification is a new legal requirement designed to improve transparency and prevent fraud in company registrations. Every company director, person with significant control (PSC), and authorised agent must have their identity confirmed before they can file or manage company records at Companies House.
This is a major shift from the old system, where basic checks were limited. Now, the aim is to ensure every filing can be traced back to a verified individual.
Key Deadline: 18 November 2025
The latest update confirms that identity verification becomes mandatory from 18 November 2025.
- There will be a 12-month transition period ending in November 2026.
- After that, unverified individuals will no longer be able to act as directors or file documents.
Voluntary verification has been available since April 2025, but from November it becomes compulsory.
Who Needs to Verify?
The rules apply broadly. Those required to complete UK company identity verification include:
- All company directors (including shadow directors)
- All PSCs (persons with significant control)
- All individuals who file on behalf of companies (accountants, secretaries, agents)
If a director or PSC fails to verify, they risk being removed from company records.
How to Complete the Verification
There are three main routes to complete UK company identity verification:
- GOV.UK One Login – the new central government login system.
- Post Office in-person verification – showing ID documents face-to-face.
- Authorised agents – accountants or service providers registered as ACSPs (Authorised Corporate Service Providers).
For most business owners, GOV.UK One Login will be the quickest. However, some may prefer using their accountant as an intermediary, particularly when multiple directors are involved.
What Happens If You Don’t Verify?
Failure to complete UK company identity verification has serious consequences:
- Unverified directors will not be allowed to act.
- Companies could be prevented from filing annual accounts or confirmation statements.
- Penalties and fines may be applied.
- Ultimately, Companies House may strike off non-compliant companies.
These are not optional rules. Compliance is now a matter of company survival.
Costs and Options: DIY vs Agent Services
Verification via GOV.UK One Login is free. But many accountants and agents are now offering verification support as a paid service.
- Typical costs range between £45–£250 per person.
- Using an agent may save time but adds recurring costs for each new director or PSC.
- Doing it yourself is free but requires handling the process directly.
Each company should weigh convenience versus cost, but outsourcing to a trusted ACSP like AG Accounting Solutions LTD can save time and reduce risk.
Timeline of Related Changes
The November 2025 deadline is part of a wider package of Companies House reforms:

- April 2026 – Joint filing of accounts and tax returns ends.
