Evidence rules for Companies House data

Effective 7 October 2026.

The rules CompanyGuard follows when it reads Companies House, raises an action and closes a case. They exist so that a gap in the data is never shown as good news.

1.What is checked

Sources
Each check reads the company profile, filing history, officers and persons with significant control (PSCs) from the public Companies House service.
Request limit
One check makes at most 16 requests: one for the profile and up to 5 pages of 100 items for each of the three lists. A longer list is kept as partial.
How often
An active company in a practice with monitoring access is checked again once its last check is more than 24 hours old. Paused and archived companies are not checked.

2.Deadlines

Urgent
An accounts or confirmation statement deadline that is overdue or due today.
Upcoming
A deadline due within the next 30 days.
Nearest first
Only the nearest deadline sets a company's state.
Stale evidence
Evidence older than 48 hours is not used. The company is shown as unavailable, never as healthy, until a newer check succeeds.

3.Changes

Supported changes
Company status, registered office, accounts due date, confirmation statement due date, new filings, officers and PSCs added or removed, officer resignations, PSC cessations and changes to a PSC's nature of control. Other fields are not monitored.
Complete lists only
A list is compared with the previous one only when every page was read. A partial or failed read never counts as a removal.
No duplicates
Repeated identical checks do not raise the same change twice, and a failed check is recorded as a source problem, not as a change.

4.Identity evidence

Verified
Shown only when Companies House states an identity verification date or a supplied verification statement for the officer or PSC.
Action due
Shown when Companies House states a verification statement is due.
UNKNOWN
Everything else: a missing field, a list that was not read in full, or dates that do not settle the question. UNKNOWN is never turned into a conclusion.

5.Closing cases

Verified closed
A case closes as verified only when newer evidence meets its rule: a later due date for a deadline case, a recovered source for a source case, or newer verified identity evidence for an officer or PSC case.
Other changes
Other material changes cannot be closed as verified automatically. Your team records the decision and its reason.
Reviewed and dismissed
Reviewing an inbox item or dismissing a case is a decision, not proof. Neither counts as verified.
Reopening
When later evidence conflicts with a verified closure, the case reopens. Earlier decisions and verification attempts stay in its history.

6.Records and notifications

Dossier
Each case has a print-friendly HTML dossier with source links, owners, decisions and verification history. Opening it does not prove a PDF was saved.
Archive
Archiving a company frees plan capacity and keeps its history. It is not deletion and does not close its cases.
Notifications
Email and browser notifications depend on each recipient's settings. SMS is currently disabled.

Questions

Questions about the evidence

What counts as a verified closed case?
A case awaiting verification closes only when newer supported Companies House evidence satisfies its rule: a later matching filing due date, recovered source or verified officer/PSC identity evidence. Missing, stale or unsupported evidence remains UNKNOWN. Reviewed and dismissed are separate decisions; conflicting later verification reopens a verified closed case.
What is a case dossier?
A dossier is print-friendly HTML with source links, ownership, decisions and verification history. It is not a generated PDF, and a served page does not prove a saved download.
How does CompanyGuard show its evidence?
Each result includes the Companies House source, retrieval time and source health. Missing identity-verification evidence is shown as UNKNOWN rather than inferred.
