Companies House ID checks: what directors must do

Since 18 November 2025, every company director and person with significant control has to verify their identity with Companies House. Here's what that means for you.

Updated September 2026 · 4 minute read

Companies House now checks who is running and controlling UK companies. From 18 November 2025, identity verification became a legal requirement for directors, people with significant control (PSCs) and LLP members.

Who needs to verify

  • New directors must verify before they're appointed.
  • Existing directors must verify by the time their company files its next confirmation statement after 18 November 2025.
  • People with significant control who aren't directors have their own deadline, set by Companies House during the 12-month changeover.

How to verify

There are two ways:

  1. Directly with GOV.UK One Login. You verify online or in the GOV.UK ID Check app, usually with a passport or photocard driving licence.
  2. Through an Authorised Corporate Service Provider (ACSP). These are firms registered with Companies House, such as some accountants, solicitors and formation agents, who check your identity for you.

Once you're verified, you get a Companies House personal code. You'll need it when you're appointed as a director or when your company files its confirmation statement, so keep it somewhere safe.

What happens if you don't

Not verifying on time is an offence. Companies House says the consequences include financial penalties, and you won't be able to make filings for your company or start a new one. It has said it expects to start compliance action by the end of 2026.

Does AI Address's ID check count?

No. We check your identity before you use our address, to keep it trusted. That's separate from Companies House, so you still need to verify with them directly or through an ACSP.

A good moment to check your address

If your company's registered office or your service address is your home, it's public on the register. While you're sorting out your ID, it's worth moving those addresses somewhere else.

Keep your home address off the register

AI Address gives you a registered office and a director's service address in Northwich, with your post scanned to your phone.
