Companies House’ voluntary window to validate your identity is coming to end on the 18 November 2025 with the checks becoming mandatory from that date.

Business owners and directors that own or work for a UK registered company will soon be required to complete an identification check using Companies House Identity Verification (IDV) service.

The changes don’t just affect you, other individuals operating within your company may also need to complete an identity check.

It is best you complete the checking process as early as possible and utilising the voluntary window is your opportunity.

Who needs to complete an identity verification check?

From 18 November 2025, business owners, directors and any people with significant control (PSCs) of a UK registered company must complete an identity verification check.

There is a 12-month window in place for existing business owners and directors to complete their checks, so you have until 18 November 2026 to ensure Companies House have the most up to date and accurate information.

For any new directors and PSCs appointed after the law comes effect will need to complete the check as quickly as possible.

In addition to this, the check is also a requirement for anyone who is a member of a limited liability partnership (LLP).

There are further plans to introduce these measures for people who file at Companies House, limited partnerships, corporate directors of companies and members of LLPs and any officers of corporate PSCs.

Failing to complete an identity check will result in some form of punishment or sanction so its important you complete your checks as soon as possible to avoid the risk of a financial penalty.

Why has Companies House introduced this service?

Companies House have introduced digital identity checks in a bid to improve and enhance the accuracy and reliability of company information.

They are keen to take a front foot approach to combat any criminal activities such as fraud and other economic crimes like money laundering.

The initiative aligns with the Government’s Economic Crime and Corporate Transparency Act 2023 which is in place to tackle criminal activity within businesses and ensure all information is valid and correct.

How can I complete my identity check?

There are two ways you can complete the verification check. You can do this directly through Companies House or use an Authorised Corporate Service Provider (ACSP).

If you’re completing your check via Companies House, you can use the Gov.UK One Login. For the check you will need your passport as this will contain the biometric chip required to validate your identity. You cannot use an out-of-date passport during this process.

You will also need your driving license or a provisional license if you have that and details of your current address on official documents such as HM Revenue and Customs (HMRC) letters or bank statements and the year you moved into the property.

Alternatively, you can complete your identity check via an ACSP. These are companies or individuals involved in any anti-money laundering (AML) combating activities.

These include solicitors, accountants and chartered secretaries and government professionals. The checks run by ACSPs must meet the same requirements as those validating information via Companies House directly.

ACSPs can file the details with Companies House and confirm you have completed a digital identity check.
