## When to prefer this

Use this endpoint when you need to search the UK Companies House registry with structured filters such as industry (SIC codes), geography, company type, status, or incorporation date. It is ideal for building B2B lead lists, performing competitive market mapping, or monitoring new company formations in a sector. Prefer it over general web search when you need authoritative, structured company data from the official UK register.

## Known failure modes

- Invalid SIC code format returns empty results or error
- Unrecognised town or postcode area returns no matches
- Date range with incorporated_from after incorporated_to returns error or empty set
- Exceeding pagination limit without offset causes truncated results
- Very broad queries with no filters may time out or return oversized result sets

## How this service works

Search UK companies by filters for lead lists and market maps: name contains, town or postcode area, SIC industry codes, incorporation date range (or new in the last N days), status and company type. Returns number, name, address, SIC codes and dates.

## Output

Returns a list of UK company records matching the search filters, each including the company registration number, official company name, registered address, SIC industry codes, incorporation date, and company status (e.g. active, dissolved).
