# Data Sources

## UK Legal Entities and associated persons

Our primary data source for UK-registered entities and associated persons is Companies House, from whom we receive regular quarterly, weekly, daily and real-time data feeds about a variety of data in the public record, as well as daily deliveries of scans of newly processed filed documents. We also receive daily deliveries of newly filed machine-readable company accounts.
