Companies House identity verification

Preparing directors and people with significant control for identity-verification requirements.

Last reviewed: 27 July 2026Review due: 6 April 2027

Overview

Companies House reforms require relevant people to verify their identity and connect the verified identity to company roles. The implementation is phased and official requirements can change, so companies should rely on the current Companies House service and guidance rather than old screenshots or third-party summaries.

Who this applies to

Directors, people with significant control, relevant officers and agents filing on behalf of companies.

Key points

  • Use the official Companies House process or an authorised corporate service provider where appropriate.
  • Names and personal details should be consistent across documents and the register.
  • Keep personal codes secure and do not send them through insecure channels.
  • Verification does not replace the company’s normal filing obligations.

Important dates and deadlines

The deadline depends on the person’s role, appointment date and the implementation timetable. Companies House communications and the public register should be checked for the applicable date.

Practical checklist

  1. Check each director and PSC record.
  2. Identify people who still need verification.
  3. Use current official instructions.
  4. Record completion securely.
  5. Review new appointments before filing.

Frequently asked questions

Is the company authentication code the same as a personal code?

No. They serve different purposes and both should be protected.

Can an accountant verify clients?

Only where the firm and process meet the authorised corporate service provider requirements.
