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 55 per cent of them and London alone 42 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: 06100, registered office in London, incorporated in the last ninety days, from a pool of 1,172. 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 06100
SIC 06100 reads as division 06 (extraction of crude petroleum and natural gas), group 061, class 0610, then the full five digits, inside section B, mining and quarrying. A company picks its own codes, up to four, and Companies House does not check them, so 06100 is the company's own description of what it does, and 1,167 list it first where 1,172 list it anywhere.
Who sells into division 06
A large share of this division is corporate structure rather than operations: licence-holding vehicles, joint venture entities and subsidiaries of much larger groups. That makes it a poor list for volume selling and a good one for mapping.
About SIC 06100
How many UK companies use SIC code 06100?
1,172 active UK companies list 06100 (Extraction of crude petroleum) among their registered SIC codes. Each company may register up to four. Of those, 1,167 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Why do so many companies list 06200 as a secondary code?
Because natural gas is frequently one activity among several for an energy business. Only about a third of the companies carrying 06200 put it first. If you want gas extraction specifically, filter to first position. If you want everyone with a stake in it, match any of the four SIC positions and expect a broader, more corporate list.
