Company search
Search UK company records
Search by company name, or enter a registration number for an exact lookup. Numbers keep their leading zeros and letter prefixes.
How this search works
Your search is sent to the Companies House Public Data API and matched against registered company names and numbers. Results are cached briefly so repeat searches do not use extra capacity.
Results are paginated. Filtering a page of results does not filter the whole register, so we do not present it as though it does.
Search tips
- Use the registered name rather than the trading brand where you know it.
- Keep leading zeros: 00445790, not 445790.
- Prefixed numbers are valid: SC, NI, OC, SO.
- Sole traders are not registered at Companies House and will not appear.
