Companies House Identity Verification: What Every UK Director Needs to Know

Companies House introduced mandatory identity verification for all UK company directors, PSCs, and those who file on behalf of companies. This is the biggest change to company registration in decades, designed to combat fraud and improve transparency in the UK business register. Here's everything you need to know about the requirements, how to verify your identity, and the deadline you cannot afford to miss before the 12-month transition period closes.

Why Is Identity Verification Being Introduced?

The Economic Crime and Corporate Transparency Act 2023 (ECCT Act) gives Companies House new powers to verify the identity of people setting up, running, and controlling UK companies. Previously, anyone could register as a director using false details, with minimal checks on whether they were who they claimed to be.

This created problems:

• Fraudulent companies registered using stolen identities
• Money laundering through shell companies with untraceable directors
• Economic crime facilitated by anonymous company structures
• Innocent victims whose identities were used without consent

The new verification system requires everyone associated with UK companies to prove they are who they say they are, creating a more trustworthy and transparent register.

What the ECCT Act Changes

The changes affect everyone involved with UK companies, from directors and shareholders to accountants and company formation agents.

Who Needs to Verify Their Identity?

Identity verification applies to a wide range of people connected to UK companies.

Directors

All directors of UK limited companies must verify their identity. This includes:

• Directors of private limited companies (Ltd)
• Directors of public limited companies (PLC)
• Directors of limited liability partnerships (LLP)
• Shadow directors and de facto directors
• Proposed directors (before they can be appointed)

If you're currently a director, you'll need to verify your identity to continue filing with Companies House. New directors cannot be appointed unless they've completed verification.

People with Significant Control (PSCs)

PSCs who own more than 25% of shares, hold more than 25% of voting rights, or otherwise exercise significant control must verify their identity. For most small companies, the PSC and director are the same person, so one verification covers both roles.

Authorised Corporate Service Providers (ACSPs)

Accountants, solicitors, and company formation agents who file documents on behalf of clients must register as ACSPs and verify their own identity. They can then verify their clients' identities as part of their service.

Since 18 March 2025, only registered ACSPs can form companies or file certain documents on behalf of others. Unregistered agents can no longer submit filings.

Filing Agents and Representatives

Anyone who files documents with Companies House on behalf of a company (other than the directors themselves) needs to be connected to a registered ACSP or verify through another approved route.

Key Dates and Deadlines

Identity verification is now live. These are the dates you need to know:

The ACSP Registration Deadline: 18 March 2025

If you use an accountant, solicitor, or company formation agent to file documents with Companies House, they had to be registered as an ACSP by 18 March 2025. Since that date, unregistered agents cannot:

• Form new companies
• File confirmation statements
• Submit changes to company details
• Act as an intermediary for filings

Action required: Check with your accountant or agent that they're registered as an ACSP. If they're not, you'll need to find an alternative provider or file documents yourself.

Existing Directors: When You Actually Need to Verify

Identity verification became mandatory on 18 November 2025, starting a 12-month transition period that runs to 18 November 2026. Within that window, exactly when you need to verify depends on your role:

• Directors (whether or not they are also a PSC) give their Companies House personal code as part of the company's next confirmation statement filed after 18 November 2025. There is no separate deadline to track: it is tied to whenever your company's confirmation statement is next due.
• PSCs who are also directors provide their personal code within 14 days starting the day after the company's confirmation statement date.
• PSCs who are not directors provide their personal code within the first 14 days of their birth month.

Important: Don't wait until the transition period is nearly over. Verify as soon as possible, well before your company's next confirmation statement is due, to avoid a last-minute rejection. See every deadline for your company, including identity verification.

New Directors and PSCs: Immediate Requirement

Since 18 November 2025, new directors and PSCs must verify their identity before they can be appointed or registered. This means:

• Company formation requires director verification first
• Adding new directors to existing companies requires verification
• New PSCs must verify when they are registered

Plan ahead if you're about to incorporate a company or appoint new directors.

What Is a Personal Code?

When you successfully verify your identity, Companies House issues you a personal code. This is a unique identifier that links your verified identity to your role as a director or PSC.

How Personal Codes Work

Your personal code proves you've been verified. When you're appointed as a director, file a confirmation statement, or make other filings, your personal code confirms your identity without needing to re-verify each time.

One Code, Multiple Roles

If you're a director of several companies, you only need one personal code. The same code works across all your directorships. This is different from authentication codes (which are company-specific) or WebFiling passwords (which are user-specific).

Keeping Your Personal Code Secure

Your personal code is linked to your verified identity. Keep it secure like any other credential. Don't share it with others or use it to verify someone else's identity. If someone else uses your personal code, you could become linked to companies you have no connection with.

How to Verify Your Identity

There are three ways to verify your identity with Companies House:

Option 1: GOV.UK One Login (Recommended)

The primary verification method uses GOV.UK One Login, the government's digital identity service.

What you'll need:

• A UK passport, UK driving licence, or other accepted photo ID
• A smartphone or device with a camera
• Your personal details (name, date of birth, address)

The process:

1. Go to the Companies House verification service (live now at gov.uk)
2. Sign in or create a GOV.UK One Login account
3. Upload or photograph your identity document
4. Take a photo of yourself (liveness check)
5. The system compares your photo to your ID document
6. If successful, receive your personal code

The online process takes about 10-15 minutes and provides immediate results in most cases. Some verifications may require manual review, which takes longer.

Option 2: Through an ACSP (Accountant or Solicitor)

If you already use an accountant, solicitor, or company formation agent registered as an ACSP, they can verify your identity on your behalf.

How it works:

• Your ACSP performs identity checks as part of their anti-money laundering (AML) obligations
• They confirm your identity to Companies House
• You receive your personal code without completing online verification yourself

This is often the easiest option if you already work with a professional adviser. They've likely already verified your identity for AML purposes, so it may involve no additional work on your part.

Eligibility: Only registered ACSPs can verify clients. Check that your adviser has completed ACSP registration before relying on this route.

Option 3: In-Person at the Post Office

If you cannot verify online (for example, if you don't have accepted photo ID or can't complete digital verification), you can verify in person at participating Post Office branches.

What you'll need:

• Acceptable identity documents
• Booking or reference number from the verification service
• Possibly additional documents depending on your circumstances

The process:

1. Start the verification process online
2. Select in-person verification when prompted
3. Book an appointment at a participating Post Office
4. Attend with your documents
5. Post Office staff verify your identity
6. Results sent to Companies House
7. Receive your personal code

In-person verification takes longer than online but provides an accessible alternative for those who can't use digital services.

Step-by-Step Verification Guide

Here's a detailed walkthrough of the verification process.

Step 1: Gather Your Documents

Before starting, ensure you have:

• Photo ID: UK passport, UK photocard driving licence, or other accepted ID
• Access to your email: For verification codes and confirmation
• Device with camera: Smartphone or computer with webcam
• Good lighting: For taking clear photos of yourself and documents

Step 2: Access the Verification Service

Visit the Companies House verification service via gov.uk. You'll be directed to sign in or create a GOV.UK One Login account.

Step 3: Create or Sign In to GOV.UK One Login

If you've used other government services online, you may already have a GOV.UK One Login. Sign in with your existing credentials. Otherwise, create a new account using your email address.

Step 4: Enter Your Personal Details

Provide your:

• Full legal name (as it appears on your ID)
• Date of birth
• Current residential address
• Previous addresses if you've moved recently

These details must match your identity document.

Step 5: Upload Your Identity Document

Either upload a photo of your ID or use your camera to photograph it in real-time. The system needs clear images of:

• The front of your ID (photo page)
• The back of your ID (if applicable)
• Any security features the system requests

Ensure the images are in focus, well-lit, and show the entire document without glare or shadows.

Step 6: Complete the Liveness Check

To prove you're a real person (not someone using a stolen photo), you'll need to take a live photo or short video of yourself. The system compares this to the photo on your ID document.

Tips for the liveness check:

• Use a plain background
• Ensure good, even lighting on your face
• Remove glasses if asked
• Follow any on-screen instructions exactly
• Don't let anyone else appear in frame

Step 7: Wait for Verification

Most verifications complete automatically within minutes. If manual review is required (for example, if the photos aren't clear or there's a query), it may take several days.

Step 8: Receive Your Personal Code

Once verified, you'll receive your personal code. This will be:

• Displayed on screen after verification
• Sent to your email
• Available in your Companies House account

Store your personal code securely. You'll need it for future filings.

Confirmation Statements and Identity Verification

Here's the critical point many directors miss: confirmation statements are rejected without verified director personal codes.

How This Affects Your Annual Filings

Companies House now checks that all directors have verified their identity before accepting a confirmation statement filed after 18 November 2025.

The Risk of Rejection

If your confirmation statement is rejected, you cannot comply with your filing obligation. This could lead to:

• Companies House sending warning letters
• Publication of strike-off notice in The Gazette
• Potential strike-off of your company
• Director disqualification proceedings

Given that confirmation statements must be filed within 14 days of your review period ending, there's no time to scramble for verification at the last minute.

What Directors Should Do Now

1. Mark your calendar: Note when your company's next confirmation statement is due, since that is when directors must provide their personal code
2. Verify early: Don't wait for your confirmation statement deadline
3. Check all directors: Ensure every director of your company verifies
4. Keep codes safe: Store personal codes securely for future reference
5. Update your records: Inform Companies House of any name or address changes before verifying

What Happens If You Don't Verify?

Failing to verify your identity has serious consequences:

For Directors

• Cannot be newly appointed as a director
• Cannot file confirmation statements (leading to strike-off risk)
• May be unable to file certain other documents
• Existing directorships could be challenged

For Companies

• Unable to appoint new directors
• Confirmation statements rejected
• Risk of being struck off the register
• Unable to demonstrate proper governance

For ACSPs (Accountants and Agents)

• Cannot file on behalf of clients after 18 March 2025
• Must return work to clients or refer to registered providers
• Risk of regulatory action for non-compliance

Companies House Fee Increases Alongside These Reforms

Companies House has also raised its fees as part of the same wave of reforms:

Every limited company must file a confirmation statement at least once a year, so this is a meaningful increase in the annual cost of keeping a company on the register. If you have several dormant or holding companies, it's worth reviewing whether all of them still earn their keep. Track exactly what each of your companies owes and when on our company deadlines tracker.

Software-Only Accounts Filing From April 2028

Separately from identity verification, Companies House is moving accounts filing to software only. Its web and paper filing services will close for accounts, and the change now takes effect from April 2028, a year later than the April 2027 date first planned (GOV.UK announcement).

If you file your accounts yourself through the Companies House website today, you'll need to use accounting software to file them from April 2028. Most accounting software already produces accounts in the tagged (iXBRL) format Companies House reads automatically.

Common Questions About Identity Verification

Do I need to verify if I'm the only director and shareholder?

Yes. Every director must verify, regardless of company size or structure. Being a sole director doesn't exempt you from verification requirements.

What if my name on official documents doesn't match my current name?

You must verify using documents that match the name on your identity document. If your name has changed (marriage, deed poll, etc.), update your ID documents first, then verify. Alternatively, update your directorship records to match your current legal name.

Can I verify using a non-UK passport?

GOV.UK One Login typically accepts UK passports and driving licences. If you only have non-UK identity documents, the ACSP or Post Office routes may be available.

What if I don't have photo ID?

The in-person Post Office verification may accept alternative documents. Companies House will confirm what's accepted for those without standard photo ID. If you genuinely cannot verify, contact Companies House for guidance on your specific situation.

How long does verification last?

Once verified, your personal code remains valid indefinitely (unless your details change significantly). You don't need to re-verify annually.

Can someone else verify on my behalf?

Only registered ACSPs can verify clients' identities. You cannot ask a friend or family member to complete verification for you. If you cannot verify yourself, use a professional ACSP or the in-person Post Office service.

What if verification fails?

If your verification is unsuccessful, you'll receive guidance on why. Common issues include:

• Photos not matching (retake clearer images)
• Details not matching documents (correct any errors)
• Technical issues (try again or contact support)
• Fraud concerns (Companies House may investigate)

You can retry verification after resolving any issues.

Is my personal data safe?

Companies House works within government data protection standards. Your identity documents are used only for verification and are not stored longer than necessary. However, your verified name and personal code are linked to the public register.

What about overseas directors?

Directors based outside the UK may face additional verification challenges. Options include ACSP verification or a Post Office-equivalent in-person route where available.

Do I need to verify for each company I direct?

No. One personal code covers all your directorships. Verify once, then use the same code across all companies where you're a director.

How Identity Verification Affects Company Formation

Since 18 November 2025, forming a new company works differently:

Before 18 November 2025

1. Choose company name and structure
2. Prepare articles of association
3. Submit incorporation documents
4. Receive certificate of incorporation
5. Directors automatically appointed

Since 18 November 2025

1. Directors verify their identity first
2. Receive personal codes
3. Choose company name and structure
4. Prepare articles of association
5. Submit incorporation documents with personal codes
6. Receive certificate of incorporation
7. Directors confirmed as verified

The key change is that directors must verify before incorporation, not after. This adds a step but ensures all UK company directors are verified from day one.

Impact on Company Formation Agents

Formation agents must be registered ACSPs to continue forming companies on behalf of clients. If your preferred agent isn't registered, they won't be able to help you after 18 March 2025.
