Companies in Carmarthenshire: 2,030 live UK companies by industry

2,030 live companies name Carmarthenshire as the county of their registered office in the Companies House snapshot dated 1 November 2026. 134 were incorporated in the last 12 months and 98 have an accounts due date that had passed. Most registered addresses leave the county blank, so this counts the addresses that name it, not every company in the county; the town and region pages count by postcode.

SpecStream is the live web data engine for teams and agents. It reads the Companies House free company data every month, and this page is that reading. Ask for the companies you track by industry, place or incorporation date and each new company, strike off proposal or overdue accounts date arrives in your sheet, CRM, Slack or agent.
