One sector and one town gives you a list you can actually work through this week. Widen it once you know what converts.
How it works
ClientFinch turns the Companies House register into a list of real sales opportunities: businesses that fit, with a researched reason to contact each one. Here’s the workflow, step by step.
Choose the SIC industry codes you work with, a town or postcode and an incorporation date range. Add a company name if you are looking for someone specific. Only legally active companies are listed.
Open any company to see its registered office, incorporation date, company type, status and SIC codes. Then check its website and search presence using our step-by-step guides to find the specific opportunity.
Save the companies that fit, note the gap you would help with, and export your shortlist to CSV for your CRM or outreach tool.
Inside the product

Better results
The tool does the searching. These habits make the shortlist worth working through.
01

02
Businesses in the same trade often register under neighbouring codes. Add two or three to avoid missing good prospects.
03
Registered offices are often an accountant’s address. Search the company itself before you reference a location in outreach.
04
Spend five minutes on each prospect’s site: speed, mobile layout, page titles and clear calls to action. Our guides show you how.
05
If you cannot write one sentence in the notes about why a company needs you, it probably does not belong on the list.

FAQ
Yes, in a limited rollout. For companies with a Verified Website, ClientFinch highlights evidence-backed website improvement opportunities you can use in your pitch. Analyses are added daily, so not every company has one yet, and our free guides show how to review a site yourself too.
Search results and company profiles come directly from the Companies House Public Data API, the official register of UK companies. ClientFinch does not buy, scrape or resell contact lists.
