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 36 per cent of them and London alone 27 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: 72190, registered office in London, incorporated in the last ninety days, from a pool of 13,291. 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.

SIC 72190 reads as division 72 (scientific research and development), group 721, class 7219, then the full five digits, inside section M, professional, scientific and technical activities. A company picks its own codes, up to four, and Companies House does not check them, so 72190 is the company's own description of what it does, and 5,637 list it first where 13,291 list it anywhere.
Who sells into division 72
Investors, grant consultants and R&D tax relief advisers watch these codes closely. A new 72110 or 72190 company often follows a funding award or a spinout agreement.
