How to find UK companies by industry
The way to find UK companies in a specific industry is to search the register by SIC code — the official classification of what each company does. Pick the SIC code(s) for your target industry, then narrow by location and incorporation date to produce a clean, current list you can export. Company Shark groups related SIC codes into industries to make this easier.
From industry to a prospect list
Choose the SIC codes that match your target sector — for example construction (41, 42, 43) or software (62) — and run an SIC search across the live register. Add a location filter to focus on a town or region, and a date-from filter to find businesses incorporated recently, which is powerful for reaching new companies before competitors do.
Because the data is live Companies House data, the list reflects the official register at the moment you search, and every result can be exported with director and address details for B2B prospecting.
Frequently asked
Which plan do I need to search by SIC code?
SIC code filtering is included on the Business plan (£15/month) and MAX. Free and Pro users can still search by location and date.
Can I target newly-registered companies?
Yes. Combine an SIC code with an incorporation date-from filter to list only companies registered in your chosen window.
How many results can I export?
Business plans allow up to 10,000 exports per month in CSV, Excel, JSON or PDF; MAX is unlimited.
What if a company picked the wrong SIC code?
SIC codes are self-reported, so some businesses use generic codes. Searching several related codes for an industry catches more of the real population.
