Companies House is changing. Here's what affects you.
Three changes matter most for directors and small companies over the next few years.
Director identity verification
Every director and person with significant control must verify their identity, either through GOV.UK One Login or an authorised agent. Existing directors verify when they file their next confirmation statement.
ACSP requirements for filing agents
Agents who file for companies, or verify identities, must register as an Authorised Corporate Service Provider (ACSP). Check that whoever files for you is registered.
Software-only accounts filing
Accounts will have to be filed with software in iXBRL format, ending paper and web-form filing. Abridged accounts are also being removed, so small companies will need to file a profit and loss account.
Dates are subject to Companies House confirmation. We update this page when new guidance is published. Last reviewed November 2026.
