Companies House API & UK Company Intelligence.
Real-time access to every UK company profile, filing, officer record, and PSC chain — enriched with FCA register status, sanctions checks, and iXBRL financial parsing in one unified API.
Real-Time Company Lookup
Search by company name, number, or SIC code and get an instant response including status, officers, charges, insolvency, and registered address — all fetched live from Companies House. No stale cache.
Filing History & Document Access
Access the complete filing history for any UK company with direct download links to original PDF documents. Includes annual accounts, confirmation statements (CS01), share allotments (SH01), and all other filing types.
iXBRL Financial Extraction
Go beyond raw PDF accounts. The Glasshouse API parses machine-readable iXBRL financial filings to surface revenue, net worth, cash at bank, and total assets in a structured, queryable format — with multi-year trend data.
More than a Companies House wrapper.
The Companies House public API returns company data in isolation. The Glasshouse API connects that data to Land Registry property ownership, FCA register regulatory status, the PSC Snapshot for beneficial ownership, and global sanctions and PEP databases — so a single company lookup gives you a complete intelligence picture.
Entity resolution is applied automatically: the same person appearing as a director in Companies House and a beneficial owner in Land Registry is merged into a single canonical record, eliminating duplicate matching work from your pipeline.
Batch processing and bulk ingestion.
For large-scale compliance workflows — onboarding portfolios, screening supplier lists, or running annual AML reviews — the Glasshouse bulk import pipeline lets you submit entity lists and receive enriched results across all data sources without per-request overhead.
Results are structured, paginated, and include source provenance for every field, making it straightforward to ingest into your own data warehouse or compliance platform.
