    Questions

    How do I monitor a United Kingdom company for changes?

    Look the company up by Company number or name, open its record, and add it to your watchlist. We re-query the Companies House on a schedule and alert you when a published field differs from the last snapshot.

    What Companies House changes can be detected?

    Legal name change; Registration status change (active, struck off, dissolved); Registered address change; Legal form change; Director appointment or resignation; New filing (accounts, confirmation statement). Anything the Companies House does not publish cannot be detected — we never infer a change from a third-party source and label it official.

    Does this replace checking the Companies House directly?

    No. The Companies House at https://find-and-update.company-information.service.gov.uk/ remains authoritative and free to search. Monitoring exists so you do not have to re-check it manually for every company you care about.

    How much does United Kingdom registry monitoring cost?

    Monitoring up to 3 companies is free. Lookups are free and need no account.
