From 18 November 2025, all company directors and people with significant control (PSCs) will be legally required to verify their identity at Companies House. This verification is being phased in over 12 months and Companies House is contacting companies directly with guidance regarding what needs to be done and by when.

These changes are intended to help ensure that people setting up, running and controlling companies are who they say they are. An estimated 6 to 7 million people will need to verify their identity by November 2026. The verification process will usually be a one-time requirement. Verification can be undertaken directly with Companies House through GOV.UK One Login or via an Authorised Corporate Service Provider (ACSP).

If you are using GOV.UK One Login you will be asked simple questions to find the best way for you to verify your identity. You must provide answers about yourself, not your company. Depending on your answers, you will then be guided to verify:

• with an app 
• by answering security questions online 
• by entering your details from your photo ID on GOV.UK One Login first, then going to a participating Post Office

To verify your identity at Companies House, you can use the GOV.UK online verification service if you have one of several accepted photo identification documents. These include a biometric passport from any country, a full or provisional UK photo driving licence, a UK biometric residence permit or card or a UK Frontier Worker permit.

If you do not have any of the accepted forms of photo ID but live in the UK, there are alternative ways to verify your identity. This includes verifying your identity in-person at a Post Office or using details from your bank or building society account together with your National Insurance number.

If you are unable to verify your identity using any of the available online or in-person methods, you can appoint an ACSP, such as an accountant or solicitor to verify your identity on your behalf. The ACSP must be registered with Companies House and a UK Anti-Money Laundering (AML) supervisory body. You will need to provide approved documents as evidence of your identity and the agent may charge a fee for their services.
