Definition
WebFiling is Companies House’s online service for filing company information without buying software. Directors and agents use it for confirmation statements, director and registered office changes, and unaudited accounts such as micro-entity and dormant company accounts. Since 13 October 2025 users sign in with GOV.UK One Login, and each filing still needs the company’s authentication code. From 1 April 2028 WebFiling will stop accepting accounts.
What it costs
Using WebFiling is free, and filing annual accounts costs nothing. Some forms carry a Companies House fee, such as £50 for a confirmation statement filed online (£110 on paper).
What changes in April 2028
From 1 April 2028 every company, including dormant companies, must file its accounts at Companies House through commercial software in iXBRL format. WebFiling and paper forms will no longer accept accounts, but confirmation statements, officer changes and other non-accounts filings stay on the web service. What the switch means for directors who file their own accounts is covered in filing company accounts yourself.
Signing in
Only one person can connect each WebFiling account to their One Login, so colleagues who shared a login need their own. Connecting does not verify your identity, which is a separate step.
