How Do I Register for Companies House WebFiling?

You register for WebFiling by creating a GOV.UK One Login account, then connecting it to your company using your authentication code. Your company itself is automatically set up with Companies House when it's formed, but you, as an individual, still need to register separately before you can file anything.

Key Takeaways

• Since 13 October 2025, registering for WebFiling means creating a GOV.UK One Login account, not the older email and security code process.
• Only one person can connect to a WebFiling account through their own GOV.UK One Login. Shared logins between team members no longer work.
• You'll still need your company's authentication code to connect your One Login to the company.
• Identity verification for directors and PSCs is a separate requirement from registering for WebFiling, though both now run through GOV.UK One Login.
• If we hold your company's authentication code already, check your account before starting this process, since it's ready to use whenever you need it.

Why Do I Need to Register Separately From My Company?

Because your company being on the Companies House register and you personally having access to file on its behalf are two different things. Your company is automatically set up the moment it's incorporated, but WebFiling access has to be registered individually, by you, before you can actually file anything.

How Do I Register for WebFiling?

Registering now means creating a GOV.UK One Login account and connecting it to your company using your authentication code.

1. Go to GOV.UK One Login and create an account using your email address and a password, if you don't already have one.
2. Sign in to Companies House WebFiling. You'll be prompted to connect your WebFiling access to your GOV.UK One Login.
3. Enter your company's authentication code when prompted, to link your One Login to the correct company.

Once connected, you'll be able to sign in and manage your company's filings through WebFiling going forward, using your GOV.UK One Login credentials each time.

Can Multiple People Share the Same WebFiling Login?

No, not anymore. Since the move to GOV.UK One Login, only one person can connect to a given WebFiling account through their own login. If your team previously shared a single WebFiling login between several people, that no longer works.

Each person who needs to file for a company now needs their own GOV.UK One Login, individually authorised for that company. This is worth planning for if more than one person in your business handles filings, since everyone involved will need to go through this registration process separately.

Do I Still Need My Company's Authentication Code?

Yes. Registering for WebFiling and having a company authentication code are two different things, and you still need the code to connect your One Login to your company. If you don't have it to hand, our main guide to your WebFiling authentication code covers where to find it or how to request a replacement.

If we formed your company, check your account first. Log in, select "My Companies," and check the "Company Details" section, since your authentication code may already be sitting there ready to use.

Is This the Same as Identity Verification?

No, they're related but separate. Since 18 November 2025, directors and PSCs also need to verify their identity with Companies House, which is a distinct requirement from simply registering for WebFiling access, even though both now run through GOV.UK One Login.

Our identity verification service can help if you haven't completed that separately yet.
