How the New Companies House ID System is Strengthening UK Corporate Transparency and Combating Fraud

Following public (and professionals) concern, the Companies House ID system has been overhauled to enhance transparency, accountability, and fraud prevention.

This update is part of a wider effort to restore trust in UK business regulation and close the loopholes that have allowed illicit activities to hide behind seemingly legitimate companies.

What is Companies House?

Companies House is the UK government’s official register of companies. It plays a vital role in maintaining the integrity of the UK’s corporate sector by ensuring that all registered entities comply with legal requirements.

Every UK company must disclose details of its directors and shareholders, which are made publicly accessible to promote transparency. The introduction of Companies House IDs from 18th November 2025 — unique personal identifiers for individuals involved in companies — now allows for accurate tracking of directors and beneficial owners across multiple businesses.

Why the Companies House ID Matters

The new Companies House ID delivers several crucial benefits for business transparency and public trust:

• Verification: Confirms a person’s identity and official role within a company.

• Transparency: Makes verified information accessible to the public and investors.

• Accountability: Links individuals directly to their business activities, discouraging misuse of corporate entities.

• Efficiency: Simplifies filings and reduces errors in corporate records.

Recent Reforms Under the Economic Crime and Corporate Transparency Act 2023

The Companies House reforms stem from the Economic Crime and Corporate Transparency Act 2023, granting Companies House new powers to verify identities, challenge suspicious information, and reject fraudulent company registrations.

1. Enhanced Security Measures

• Data Encryption: Personal details are now encrypted to prevent unauthorised access.

• Two-Factor Authentication: Adds an extra layer of protection when accessing accounts.

• Regular Audits: Ongoing audits ensure compliance with updated data protection standards.

2. Updated ID Format

The new ID format is clearer and easier to use, reducing data entry errors and streamlining digital filings.

3. Stricter Application Scrutiny

Applications for new company registrations now undergo rigorous verification checks, ensuring only legitimate individuals can act as company directors or shareholders.

Cracking Down on Corporate Fraud and Money Laundering

A major driver behind these reforms is the need to combat corporate fraud and illicit financial activity.

The BBC Panorama investigation recently exposed how criminals have used loopholes in the previous system to create shell companies as fronts for money laundering and organised crime, often hidden behind seemingly ordinary high street shops.

The enhanced Companies House ID system directly addresses these vulnerabilities by:

• Preventing fake registrations made with stolen or fabricated identities.

• Tracing individuals linked to multiple suspicious companies.

• Supporting law enforcement by improving data reliability and accessibility.

This marks a turning point in the UK’s commitment to financial transparency and restoring confidence in its corporate register.

Implications for Directors and Shareholders

The reforms bring both benefits and responsibilities for business leaders:

• Accuracy Matters: Directors and shareholders must ensure all details are correct and current.

• Know the New ID Format: Familiarising yourself with the new format helps prevent submission errors.

• Stay Informed: Keep up with Companies House updates to maintain compliance with ongoing reforms.

How to Update or Verify Your Companies House ID

If you’re a director or shareholder needing to update your details:

1. Log in to your Companies House account.

2. Access your profile and review your personal details.

3. Update your information as required.

4. Submit changes for Companies House review.

5. Check confirmation once the updates appear in the register.

   
   

Technology’s Role in Corporate Identity Management

The digitalisation of corporate administration is accelerating:

• Online Platforms: Simplify registration and compliance processes.

• Blockchain Technology: Being explored to create tamper-proof, verifiable records of company ownership and control.

These innovations promise to further enhance transparency and data accuracy in the years ahead.

Conclusion

The modernised Companies House ID system is more than a technical update — it’s a major step toward safeguarding the UK’s business environment from fraud, money laundering, and misuse.

By embracing digital identity verification and stricter oversight, the UK is strengthening its position as a global leader in corporate transparency and ethical governance.

For directors and shareholders, staying proactive and informed is the key to compliance and trust in this new era of accountability.
