What it does
- Look up a company by registration number or by name, straight from the UK Companies House register. See Look up a company.
- Create a customer, vendor or contact from a company number, with the registered name and registered office filled in and your own template applied. See Create a customer, vendor or contact from a company number.
- Link the customers, vendors and contacts you already have to the register, one at a time or many at once, and see each company's status on its card. See Customers, vendors and contacts.
- Company snapshots keep what was fetched, so opening the same company twice does not cost two calls. See Company snapshots.
- Officers and filings for any company, with filed documents to download as PDF. See Company officers and Company filings.
- Filing watches check chosen companies every hour and record new filings and changes of status. See Filing watches.
- The Companies House Role Centre shows what needs attention. See The Companies House Role Centre.
- An assisted setup guide takes you from a free Companies House API key to a working connection. See Set up Companies House Lookup.
For developers
- A supported API for extensions that depend on the app: an interface for lookups, three integration events, filing watches, filed documents and read access to the data. From this version the app follows semantic versioning. See Building on D2K Companies House Lookup.
