Companies House Search: How to Find New Companies to Sell To

Why newly incorporated companies are gold for B2B

A newly registered company has no incumbent suppliers. In its first weeks the director must choose an accountant, a bank, a website provider, insurance, IT and more - and whoever makes first contact usually gets the business. The register is public, free and updated daily, which makes it the best B2B lead source many providers never use.

The skill is not finding the companies - the search is easy. It is filtering them to the ones that will actually trade and need your service.

Step by step: find new companies on the register

The Companies House advanced search makes this straightforward:

• Go to the Companies House service and open the advanced company search
• Set incorporation date to the last 7 or 30 days
• Add the SIC codes for the sectors you serve
• Filter by location if you only work locally
• Review the list and shortlist companies that look set up to trade
• Use the registered office and any public director info to build your prospect list

The SIC code filter is the most powerful lever - it turns a generic list of new companies into a list of your ideal clients.

Use SIC codes to find your ideal client

SIC codes classify what a company does, and they let you target precisely. An accountant might target all new professional-services firms; a web designer might target retail and e-commerce registrations; an IT provider might target legal and financial services.

Familiarise yourself with the codes that match your best customers and build a saved search around them, so finding new companies takes minutes rather than an afternoon.

Filter out the companies not worth chasing

Not every registration is a business about to trade. Skip dormant companies, shell registrations and businesses set up for a purpose you cannot serve. Signals of a real business include a genuine registered office (not just an accountant's address), a specific and relevant SIC code, and founders who have registered for the services they need.

Checking the incorporation details takes seconds and saves you from calling companies that will never become customers.

Turn the list into a follow-up system

A list of new companies is only valuable if you contact them in the first weeks. Build a simple cadence: a first email referencing the company by name, a follow-up a few days later, and a call the following week. The companies you contact in the first fortnight are the ones you win.

Whether you search manually or use a daily feed like 9amLeads, the advantage is the same - you are first to a brand new company with no incumbent supplier. That is the cheapest, highest-converting B2B lead there is.
