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 28 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: 91011, registered office in London, incorporated in the last ninety days, from a pool of 520. 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.

How to read SIC 91011
SIC 91011 reads as division 91 (libraries, archives, museums and other cultural activities), group 910, class 9101, then the full five digits, inside section R, arts, entertainment and recreation. A company picks its own codes, up to four, and Companies House does not check them, so 91011 is the company's own description of what it does, and 245 list it first where 520 list it anywhere.
Who sells into division 91
Ticketing and visitor management systems, EPOS and retail for gift shops, exhibition design and fit-out, conservation supplies and specialist insurance all sell into this division. Funding and grant consultants do too.
About SIC 91011
How many UK companies use SIC code 91011?
520 active UK companies list 91011 (Library activities) among their registered SIC codes. Each company may register up to four. Of those, 245 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Why do so few museums list 91020 as their first SIC code?
Because the registered entity is usually a charitable company whose objects are broader than running a museum. The first code often describes the charity in general terms and the museum activity appears second. If you want the real population, match on any of the four SIC positions rather than the first.
