Be IDV compliant

The risks are real

If your firm doesn’t verify directors or PSCs, you won’t be able to file key submissions. This could leave clients non-compliant, at risk of strike-off, and your firm named on Companies House’s public list.

Time saver

IDV is part of AML

Don’t do the same job twice. ID verification is already built into your AML process. Firmcheck lets you handle both at once, saving time and keeping everything compliant.

FAQs

Find answers to your most pressing questions about Companies House ID verification.

Who needs to complete ID verification?

All company directors, people with significant control (PSCs), and anyone filing on behalf of a company.

Do we need to verify clients again if we’ve already done AML checks?

Yes, but you can reuse much of your AML evidence. A cryptographic check (ePassport, biometric ID, etc.) may be enough if previous checks meet the new standard.

Do we need to register as an ACSP (Authorised Corporate Service Provider)?

Yes, if you want to carry out IDV and file on behalf of clients. Registration opens March 2025 and costs £55.

Can clients verify their own ID?

Yes, through GOV.UK or the Post Office. But many prefer accountants to manage it for them.

What documents are acceptable?

Passports, biometric residence permits, driving licences, and certain EU ID cards, depending on whether you’re doing cryptographic or in-person checks.

When do these rules take effect?

From 18 November 2025, all new directors and PSCs must be verified before incorporation. Existing ones must complete IDV within the 12-month transition period or before you do your next client filing.

What happens if we don’t do IDV?

You’ll be unable to file for clients, risking non-compliance, strike-off, and public listing by Companies House.

How long must we keep IDV records?

Seven years from the date of verification, including all documents and evidence of checks.

Do we need specialist training for in-person checks?

Yes, if you’re verifying IDs manually. Staff must be trained by a Home Office-approved provider in detecting false documents.

Can IDV be combined with AML?

Yes, the same ID verification can satisfy both AML and Companies House requirements if your system (like Firmcheck) records and evidences it properly.
