The way businesses file documents with Companies House is about to change significantly. Starting 13 October 2025, all users will need to access Companies House WebFiling through the GOV.UK One Login system. This update aims to improve security and simplify the login process for millions of company directors, secretaries, and agents. Understanding what this means and how to prepare can help avoid disruptions and make the transition smooth.
What Is GOV.UK One Login?
GOV.UK One Login is a single sign-on system designed to give users secure access to multiple government services with one account. Instead of managing separate usernames and passwords for each service, users will have one login credential that works across various platforms, including Companies House WebFiling.
This system uses strong identity verification methods to protect sensitive information and reduce fraud risks. It supports features like two-factor authentication and recovery options, which enhance security without making access complicated.
Why Is Companies House Making This Change?
Companies House handles millions of filings every year, from annual returns to changes in company details. Security and ease of access are critical for these services. Moving to GOV.UK One Login offers several benefits:
Improved security: Stronger identity checks reduce the risk of unauthorized access.
Simplified access: One login for multiple government services cuts down on password fatigue.
Better user experience: A consistent login process across services makes it easier to manage accounts.
Future-proofing: Aligning with government-wide digital identity standards prepares Companies House for upcoming digital improvements.
This change reflects a broader government effort to unify digital services and protect user data.
How Will This Affect Companies House Users?
From 13 October 2025, users will no longer be able to log in to Companies House WebFiling using their current credentials. Instead, they must create or use an existing GOV.UK One Login account. Here’s what users need to know:
Account creation: If you don’t already have a GOV.UK One Login, you will need to register. This involves verifying your identity with documents such as a passport or driving license.
Linking accounts: After logging in, you will link your GOV.UK One Login to your Companies House WebFiling account.
Access continuity: Your existing company data and filings will remain intact; only the login method changes.
Support available: Companies House will provide guidance and help resources to assist with the transition.
It’s important to start preparing early to avoid last-minute issues.
Steps to Prepare for the Transition
To ensure a smooth switch to GOV.UK One Login, follow these practical steps:
Check if you have a GOV.UK One Login account
Visit the GOV.UK One Login website to see if you already have an account. Many users may have one from other government services.
Register early if needed
If you don’t have an account, register well before October 2025. The process requires identity verification, which can take time.
Gather necessary documents
Prepare valid photo ID such as a passport or driving license for identity checks.
Update contact details
Make sure your email and phone number are current on your Companies House account to receive important notifications.
Follow official guidance
Keep an eye on updates from Companies House and GOV.UK for detailed instructions and support materials.
Inform your team or agents
If you use company secretaries or filing agents, ensure they are aware of the change and prepared.
By taking these steps, you can avoid delays or access problems when the new login system goes live.
What Happens After 13 October 2025?
Once the transition date arrives, all users must use GOV.UK One Login to access WebFiling. The old login method will be disabled. This means:
Users without a GOV.UK One Login will be unable to file documents or update company information.
Companies House will continue to offer support channels for users facing difficulties.
The new login system will provide a more secure and consistent experience across government services.
This change also opens the door for future enhancements, such as linking other government services related to business compliance and tax.
