Key Takeaways

• From 13 October 2025, GOV.UK One Login is required for WebFiling access
• This change means you only need one secure login for multiple government services with two-factor authentication
• Make sure your WebFiling email address is up to date and matches other accounts

• You can still file a charge (mortgage) document without connecting your account to GOV.UK One Login

What is a WebFiling Account?

A WebFiling account is an online account used to submit statutory documents to Companies House.

In WebFiling, you can:

• file your company’s annual accounts
• file your company’s confirmation statement
• file your company’s director or secretary changes and other information
• sign up to get email reminders when your company’s accounts and confirmation statement are due
• digitally authorise people to file for your company online

What is GOV.UK One Login?

GOV.UK One Login is a single sign-in system requiring only one account, username, and password, that allows users to access a variety of central government services, such as applying for an import license or cancelling a stolen passport.

Why is Companies House moving WebFiling to GOV.UK One Login?

The move to GOV.UK One Login is designed to give companies of all sizes greater security and a smoother experience when using online services. By introducing a single login, it will also provide stronger assurance about who is setting up, running, and controlling companies in the UK.

Benefits of GOV.UK One Login

Here’s what you can expect from GOV.UK One Login:

• Access to multiple government services with one set of details
• Extra protection with two-factor authentication
• The option to verify your identity for Companies House using the same login

In short, it means fewer passwords to remember and more peace of mind about the security of your account.

How to prepare for the GOV.UK One Login change at Companies House

To make sure you’re ready for the change and that your information stays safe:

• Check that the email address on your WebFiling account is up to date and accessible. You can change this under ‘Change account details’ when signed in
• If you also use a Companies House account for Find and update company information, make sure both accounts use the same email address
• If you don’t already have a GOV.UK One Login, consider creating one in advance using the same email address as your WebFiling account
• If you have a Companies House account for Find and update company information, think about connecting this with GOV.UK One Login now (if you haven’t already).
• Review the companies you’re authorised to file for in your WebFiling account. You can do this by going to the ‘Your companies’ page and removing any you no longer file for

How do I connect my WebFiling account to GOV.UK One Login?

When you try to sign in to WebFiling from 13 October 2025, you’ll be redirected to connect your account with GOV.UK One Login.

• If you already have a GOV.UK One Login, you can simply sign in and connect your account
• If you don’t have one, you’ll be prompted to create it
• If you have a Companies House account for Find and update company information that isn’t yet connected, you’ll be able to link both accounts at the same time

You may be asked to enter each company’s authentication code to confirm you’re authorised to file for them.

Importantly, you won’t need to verify your identity just to connect your WebFiling account.

What to do if you share a Companies House WebFiling account

Only one person can connect each WebFiling account to their GOV.UK One Login.

If you currently share access with others:

• Each person will need to create their own GOV.UK One Login, with a separate email address.
• They will no longer be able to access information in the shared WebFiling account.

Can I still file a mortgage charge without GOV.UK One Login?

Yes, you will still be able to file a charge (mortgage) document without connecting your account to GOV.UK One Login.
