What is persons with significant control?
A person with significant control (PSC) is an individual registered as ultimately owning or controlling a UK company, held as a nested record under the company.
Companies House exposes PSCs through its Public Data API alongside officers, charges and filing history.
In this catalog it appears concretely: - Companies House Public Data API — "officers, PSCs, charges, insolvency, filing history".
Why does persons with significant control matter when choosing a dataset?
A table is only as good as the column you actually need. If this field is absent, sparsely populated or defined inconsistently across rows, no amount of surrounding richness rescues the analysis, so it deserves its own line in your evaluation checklist.
The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and Companies House Public Data API lets you inspect the real artifact before any budget is committed.
How do you evaluate persons with significant control in a data source?
Treat every claim of this attribute as testable:
- Open Companies House Public Data API and confirm its record — "officers, PSCs, charges, insolvency, filing history" — against the files you actually receive.
- Pin down update cadence in writing. Across this catalog, 22.6% of 1,744 datasets refresh daily and 64 still arrive only through a manual request form, so ask exactly how fresh each release is.
- Check whether definitions are verified at all. Field definitions are verified for 1495 of 1,744 datasets (85.7%), and any source you license should meet that bar.
- Price the delivery route before the license. In this catalog bulk download is the most common access method (725 datasets) ahead of official APIs (574), and 379 sources still require scraping — a maintenance cost that lands on you, not the vendor.
