What’s Companies House Identity Verification and Why Should You Care?

From 18th November 2025 it is now mandatory for all directors and persons of significant control (PSC) of a limited company or LLP to verify their identity and receive a personal code for Companies House.
This is all part of the government’s effort to increase transparency and reduce misuse of UK-registered companies especially in the property sector.

If you have existing company, you will now already have a due date to provide your personal code to Companies House and you only have a 14 day window to do this. You can check your due date by searching your company on the Companies House register.

If you are looking to setup a new limited company, you must have completed the identity verification and received your personal code, before you can incorporate.

Verify your identity yourself or use an ACSP

You can do this yourself online or you can contact us and we can do this for you as an Authorised Corporate Service Provider (ACSP) so you can stay focused on running your property portfolio.

  • We use a lead provider of Anti Money Laundering Verification to carry out the identity check
  • We verify your identity check with Companies House
  • Get your personal code emailed to you from Companies House directly.
  • Keep your identity check/anti-money laundering (AML) records for 7 years

As a trusted, long-standing accountancy firm already supervised for AML compliance, we’re fully authorised to carry out all duties on your behalf.

No, if you are a director or person of significant control of multiple companies, you only need to verify once and you can use the same code for each role you hold.

Directors:

  • You will need to provide your personal code on your next confirmation statement and you will only a 14 day window to do this.

Directors who are also a person of significant control (PSC):

  • You will need to provide your personal code on your next confirmation statement as above as a director
  • You will also need to provide your personal code separately to Companies House the day after your confirmation statement submission as a PSC.

Person of significant control (PSC) only:

  • You will need provide your personal code to Companies House within 14 days of your birth month. For example if you were born 28th March, then you will have 14 days from 1st March 2026 to 14th March 2026 to provide your personal code with Companies House.

You can find your due dates by searching your company on the Companies House Register

Companies House will show the following on the public register:

  • director and/or person of significant control's name 
  • The ACSP name - if you used one
  • names of the Anti-Money Laundering (AML) supervisory bodies the ACSP is registered with
  • date the identity checks were completed

“Following my relocation to Spain, I rented my UK property, due to poor advice I failed to submit a self assessment tax return by the date required, hence I was bombarded with letters from HMRC. I contacted Thandi Nicholls Ltd who resolved this issue and have continued to look after my Tax Return on an annual basis. Due to Brexit my UK property has been sold and I no longer have a tax liability in the UK. I found Thandi Nicholls to be professional, very easy to deal with, but most of all they removed the pressure and stress relating to the tax issues. Thank you T N, I would be more than happy to recommend this company.”
