Every UK company, on one live map
Company Map UK is live. Every company on the Companies House register, all 6.4 million of them, on a single interactive map in the browser. Free to explore, nothing to install, no account to create.
Companies House publishes the entire UK register for free. It is one of the most useful open datasets in the country, and it arrives as a single CSV of around 2.6 GB. That format is fine for a database and close to useless for actually seeing the data: which towns and streets companies cluster in, what an industrial estate looks like with every business on it, how a sector spreads across a city.
Company Map turns that register into one map. The whole country loads at once, every street can be zoomed into, and the businesses in any area can be counted and exported. It runs entirely in the browser, so there is no waiting for a server to draw each view.
What it does today
- Browse the whole register. Pan and zoom across the UK with every company plotted as a point. Search any postcode or place to jump straight there.
- Count any area. The number of companies in the current view updates as the map moves, so a town, a postcode district or a single street can be sized in seconds.
- Export what matters. The companies visible in a view can be exported to CSV with their registered addresses. Pricing is pay-as-you-go, from a penny per company, with a free demo export to try first.
Built to stay up
The map is served as static files from a content delivery network, with only the export and search requests hitting a small server. A spike in traffic reaches the CDN, not a database, so the site stays fast whether ten people or ten thousand are looking at it.
The data behind it comes straight from the Companies House register and refreshes every month as new filings land. For a longer read on how a million points render without slowing down, see how it works.
