Data sources & methodology
Where our data comes from
Every dataset on Meridian Data is sourced from official UK public records, then cleaned, structured and validated. This page sets out each source, how often it updates, how we process it, and the licence it is used under — so you can trust and cite what you find here.

How we clean and validate
- Deduplicate and normalise inconsistent fields (names, dates, amounts, sectors) into a consistent schema.
- Preserve a link back to the original source record wherever one exists.
- Run an automated validation suite on every ingestion — row counts, null rates, freshness, cross-field consistency — with alerts if a check fails.
- Surface data through dashboards and a REST API, with CSV export.
