Know every UK company.
CompaniesIQ turns the UK's public business register into market intelligence anyone can search, track and trust — around 5.5 million live companies, one source of truth.
What we do
Every company in the UK files with Companies House, but that data is hard to use. We classify, enrich and connect it with official economic statistics so founders, analysts and teams can understand a company, a sector or a region in seconds — not hours. See exactly what the product does and the data it's built on.
Where the data comes from
Everything is real and sourced. We pull live from Companies House, the ONS and Nomis, and clearly label any figure that comes from a published reference baseline. We never fabricate numbers. You can read exactly what powers each figure on our sources & methodology page.
What we believe
Public data should be genuinely usable, not locked behind one-record-at-a-time lookups or opaque scoring. So we show our working: every figure is dated and traceable, and anything we can't measure is marked “Not Assessed” rather than guessed. The signals we surface are indicators to help you decide where to look — not verdicts about any company or person.
