Ask the Expert: Companies House Q&A on Key ACSP Updates with Mark Buckley

Why are Companies House rules changing?

Companies House is being reformed under the ECCTA to strengthen the accuracy and reliability of the information on its register. Historically, Companies House had limited powers to verify or reject information, resulting in inaccuracies and, in some cases, misuse.

The ECCTA introduces sweeping changes, including:

• New identity verification requirements for those registering company information.

• Expanded powers for the registrar to refuse, query, or remove inaccurate filings.

• An overall push to enhance transparency and trust, and to combat economic crime.

These reforms mark a major shift in how Companies House operates, giving it a more active role in ensuring data integrity.

What type of ID verification meets Companies House standards?

Identity verification documentation must meet the standards set by Companies House. This includes biometric and document-based verification that ensures the individual’s identity is validated to a high standard. It’s not enough to simply “see” a passport or license; the system must verify the authenticity of the document and the identity of the individual, using either biometric data or third-party checks. Thirdfort already offers verification that meet these requirements.

Do I have to redo ID verification for longstanding clients?

Yes. Under the new rules, even existing clients must undergo Companies House-compliant identity verification. This is distinct from AML checks already completed. Verification must be current and meet the new standards, particularly when filing on the client’s behalf or updating company records.

What to do if there is a difference between legal and Companies House listed names?

When an individual's identity is verified, if there's a difference between the name used for verification (e.g., married name on ID) and the name known in the business world (e.g., maiden name), it's permissible.

The individual should provide the reason for the difference in name. As long as the dates of birth and unique identifiers match, the difference in name should not impede registration.

Are ACSPs expected to charge clients for delivering this service?

Many ACSPs are already building this into their fee structures. It is considered reasonable to charge clients for verification services, particularly given the regulatory and administrative overhead involved. Some firms offer it as part of onboarding; others treat it as a standalone compliance service.

Will suspected fraud be reported to authorities like CIFAS or the National Crime Agency?

Yes. Companies House is taking a far more proactive role in identifying and responding to fraudulent activity. If suspicious behaviour is detected - such as false identity submissions or misuse of company filings - it may be reported to fraud prevention agencies like CIFAS, and law enforcement bodies including the National Crime Agency (NCA). These collaborations form part of the broader push to tackle economic crime and protect the integrity of the UK corporate register.

Wrapping up: What ACSPs should do next

These reforms signal a new era for Companies House and for those acting as Authorised Corporate Service Providers. The shift from passive registry to active regulator means ACSPs must take greater care with the information they submit — and how they verify it.

To stay compliant, ACSPs should:

• Register promptly with Companies House as an authorised provider;

• Review and update internal processes to ensure verification meets new standards;

• Educate clients on what these changes mean for them;

• Consider leveraging digital tools — like Thirdfort — to streamline ID checks and recordkeeping.

While these changes may initially seem demanding, they represent a necessary evolution to restore trust and integrity in the UK’s corporate system. Early preparation and the right tools will put your firm in a strong position to adapt.
