Companies House ID Verification: What Every UK Company Director Needs to Do Now

If you run a small business in the UK, you’ve likely noticed that the rules around company management are tightening. The biggest change in a generation is currently landing on the desks of directors across the country: Companies House Identity Verification.

Under the Economic Crime and Corporate Transparency Act 2023 (ECCTA), the way we register and manage companies is being overhauled to prevent fraud and money laundering. For you, the business owner, this means a new "to-do" list item that cannot be ignored.

In this guide, we’ll break down exactly what these changes mean, who needs to act, and how you can ensure your business remains compliant without the stress. If you're also tracking wider filing updates, see Companies House P&L Filing Changes Delayed.

What is Companies House Identity Verification?

For decades, anyone could be named a director of a UK company with very little oversight. This loophole was often exploited for fraudulent activities. The new ID verification regime is designed to close that gap.

Starting from 18 November 2025, Companies House will begin a phased rollout of mandatory identity checks. This isn't just a one-off suggestion; it is a statutory requirement. Every person who set ups, runs, or controls a UK company must prove they are who they say they are.

Who Needs to Verify Their Identity?

The new rules cast a wide net. If you hold one of the following positions, you are "in scope":

1. All Individual Directors: Every single person listed as a director of a UK company.

2. Persons with Significant Control (PSCs): Anyone who owns or controls more than 25% of the company's shares or voting rights.

3. Relevant Officers of LLPs: Such as designated members.

4. Authorised Corporate Service Providers (ACSPs): Accountants or agents who file on behalf of companies.

Note that "Corporate Directors" (companies that act as directors for other companies) cannot verify themselves: instead, the individual humans who run those corporate entities will need to go through the process.

When is the Deadline?

Timing is everything. Companies House is introducing this over a 12-month transition period starting in late 2025. However, different roles have different triggers:

For New Directors

From 18 November 2025, if you want to appoint a new director, they must verify their identity before the appointment is filed. You won't be able to register a new appointment until the ID check is complete.

For Existing Directors

If you are already a director, your deadline is linked to your Confirmation Statement. You must be verified before your company files its next confirmation statement after the 18 November 2025 start date. If even one director is unverified, the company will be blocked from filing its confirmation statement: a serious issue that can lead to the company being struck off the register.

For PSCs (Persons with Significant Control)

PSCs have a much tighter window. Once the regime begins, a new PSC must verify within 14 days of taking on the role. For existing PSCs, you generally have a 14-day window starting from your birth month in the first year of the new system.

How to Verify Your Identity

There are two main ways to complete your verification. Companies House has tried to make the process digital-first, but help is available if you aren't tech-savvy.

1. Direct via GOV.UK

You can verify directly with Companies House using the GOV.UK One Login service. This typically involves:

• Downloading the "GOV.UK ID Check" app.

• Scanning a primary ID document (like a UK passport or photocard driving licence).

• Using your phone's camera to match your face to the ID photo.

2. Through an Authorised Agent (ACSP)

Many business owners find the digital DIY route daunting or time-consuming. This is where a business accountant uk comes in.

Accountants who are registered as Authorised Corporate Service Providers (ACSPs) can verify your identity for you. They are already supervised for Anti-Money Laundering (AML) purposes, so they can perform the check and notify Companies House on your behalf. This is often the preferred route for busy directors who want to ensure the job is done correctly alongside their usual tax and bookkeeping services.

What is a "Personal Code"?

Once you have successfully verified your identity, Companies House will issue you a Personal Code. Think of this as your unique ID badge for the UK corporate world.

You only need to verify once. Your Personal Code will then follow you across all your different roles. If you are a director of three different companies, you’ll use the same code for all of them. This code links your verified identity to your entries on the public register.

What Happens if You Don't Comply?

The consequences for ignoring these rules are significant. Companies House has been granted new powers to enforce compliance, including:

• Financial Penalties: Civil penalties and fines for directors and companies.

• Criminal Sanctions: In extreme cases of non-compliance or providing false information.

• Inability to File: As mentioned, you won't be able to file your confirmation statement. This leads to the company being "not in good standing," which can affect your ability to get bank loans, sign contracts, or sell the business.

• Public Record Notices: Your unverified status may be flagged on the public register, which could harm your business's reputation with suppliers and customers.

Step-by-Step Checklist for Directors

1. Audit Your Board: List all current directors and PSCs. Ensure their details (names, addresses) on Companies House are currently accurate.

2. Check Your Dates: Look up your next Confirmation Statement due date. This is your "hard deadline" for verification.

3. Prepare Your Documents: Ensure you have a valid, in-date passport or driving licence.

4. Decide Your Method: Will you use the GOV.UK app, or will you ask your accountant to handle it?

5. Get Your Personal Code: Once the system opens, complete the verification and store your Personal Code safely.

Final Thoughts

Identity verification might feel like another piece of "red tape," but it is a necessary step to protect the integrity of the UK business environment. By proving who you are, you’re helping to create a marketplace where fraud is harder to commit, which benefits every legitimate small business owner.

Don't wait until the week of your filing deadline to think about this. The verification process can sometimes face delays if documents are rejected or if the system is busy. Start planning now so you can focus on what you do best: growing your business.
