About Company Search
BizLookup gives you instant access to official Companies House data for every registered company in the United Kingdom. Companies House is the UK government's registrar of companies, holding records on over five million active businesses and millions more that have been dissolved or struck off. All of this data is public by law, but navigating the official interface can be slow and unintuitive. BizLookup makes it fast and simple.
Whether you are a freelancer vetting a new client, a job seeker researching a potential employer, a supplier checking creditworthiness, or an entrepreneur scoping out competitors, company data tells a story that marketing materials never will. Filing history, director appointments, registered address changes and accounts all paint a picture of how a business really operates behind the scenes.
What You Can Find
Every company record includes the registered name, company number, date of incorporation, registered office address, company type (Ltd, LLP, PLC, etc.), current status and SIC codes describing the nature of the business. For most companies you can also view filed accounts, confirmation statements, director and secretary details including appointment and resignation dates, and persons with significant control (PSCs) who own more than 25% of shares or voting rights.
Why Check a Company?
- Verify that a business is genuinely registered and active before signing contracts.
- Check director history to spot serial directors of dissolved companies.
- Review filed accounts to assess financial health before extending credit.
- Confirm the registered address matches what the company claims on its website.
- Identify persons with significant control to understand who really owns the business.
