ECCTA – mandatory UID implementation date confirmed – 18 November 2025

Companies House has now confirmed that including a Unique Identification code (UID) (also known as the personal code) will start to be mandatory from 18 November 2025.

 

Directors

• New directors will need to include their UID as part of any filing to incorporate a company or be appointed to an existing company;
• Existing directors will need to include their UID at the same time as the company files it’s first confirmation statement during the 12-month transition period (starting from 18 November 2025); and

 

PSCs

A PSC’s obligation to submit a UID to Companies House is slight more complicated!  The guidance from Companies House says (to paraphrase):

Every PSC has a 14-days from a certain point in time to provide their UID.  The starting point for the 14 days depends on if:

• they are already a PSC when identity verification requirements are introduced on 18 November 2025 or not, and
• they are also a director of the company

If they first register as a PSC after 18 November 2025, their 14-day period starts from the date they register with Companies House.

If they are already a PSC on 18 November 2025 and

• they are also a director of the company, their 14-day period starts from the company’s confirmation statement date.
• they are not a director of the company, their 14-day period starts from the first day of their month of birth, as it is shown on the Companies House register. For example, if the date of birth is shown on the register as March 1990, the 14-day period will start on 1 March 2026.

This appears unduly complex to us!  In the interests of simplicity, Kudocs plans to require users to provide UIDs for PSC at the same time as either PSC first notification or when the entity files its first confirmation statement after 18 November 2025.  Please let us know what you think about this.

 

LLPs and others

Identity verification requirements for limited partnerships, corporate directors of companies, corporate members of limited liability partnerships (LLPs), and officers of corporate PSCs will commence later.
