SIC 73110 in numbers
51,526 companies is 0.99 per cent of the 5,190,464 active companies on the UK register. 73110 is the most used of the 3 codes we track in division 73.
Only 30,098 of the 51,526 put it first. The other 21,428, 42 per cent, list it behind another code, so a search on the first code alone would miss most of them. Match any of the four positions and tighten it with a second filter.
ACTIVE COMPANIES BY REGISTERED-OFFICE POST TOWN (WHERE THE PAPERWORK SITS, NOT NECESSARILY THE WORK) · COMPANIES HOUSE PUBLIC RECORD, AUGUST 2026
The five busiest post towns hold 43 per cent of them and London alone 37 per cent. Selling nationally, those towns are most of the market. Selling locally outside them, expect a small pool, so cover a county or a region rather than one town.
A worked example: 73110, registered office in London, incorporated in the last ninety days, from a pool of 51,526. Each lead you get arrives with a working website and a real email, and the director's name when the record has one. If we cannot complete one, you pay nothing.
