Extraction of natural gas (SIC code 06200)
Extraction of natural gas is UK SIC code 06200. It sits in division 06 (Extraction of crude petroleum and natural gas) of the SIC 2007 list. On the August 2026 Companies House register, 655 active UK companies list 06200 among their SIC codes. 237 of them list it first. That makes it the second most used code in its division.
Two codes, and they behave very differently. 06100, extraction of crude petroleum, is almost entirely first-position filings: companies that really are in oil extraction. 06200, natural gas, is the opposite, with only around a third putting it first, because it is frequently carried as a secondary code by energy businesses whose main activity sits elsewhere. Read the two separately or the picture misleads you.

Who prospects SIC 06200 companies
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. Energy recruiters, offshore insurers, decommissioning contractors and specialist tax advisers all use the public record here to work out who owns what and which entities are still filing. Officer overlap between companies is often the most useful signal on the page.
Lead generation for recruiters →How to read SIC 06200
SIC 06200 is a five-digit code, and the digits are not arbitrary. The first two, 06, are the division, extraction of crude petroleum and natural gas. Add the third and you have group 062; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section B, mining and quarrying, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
More on how SIC 06200 is built
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 06200 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 06200 are London (288), Aberdeen (41), Leeds (18), Great Yarmouth (14) and Lyndhurst (14). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 06200 as a filter
655 companies is 0.01 per cent of the 5,190,464 active companies on the UK register, and ranks 06200 second most used of the 2 codes we track in division 06. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.
More on filtering by SIC 06200
Only 237 of the 655 companies carrying 06200 put it first. The other 418, 64 per cent, list it behind another code, which usually means the business does more than one thing and files 06200 as a sideline. A search that matches the first code only will miss most of this population, so match on any of the four SIC positions and use a second filter to tighten it.
The population is concentrated: the five busiest post towns hold 57 per cent of it, and London alone accounts for 44 per cent. If you sell nationally, those five towns are most of the market. If you sell locally and you are not in one of them, expect a much smaller pool and widen the radius early.
In practice the code on its own is rarely the whole filter. Pair 06200 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 06200, registered office in London, incorporated in the last ninety days, which turns a 655 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

About SIC 06200
How many UK companies use SIC code 06200?
655 active UK companies list 06200 (Extraction of natural gas) among their registered SIC codes. Each company may register up to four. Of those, 237 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.
Is a North Sea contractor's personal company in this division?
Usually not. Individual engineers and consultants contracting offshore normally sit in 09100, mining support service activities, or in an engineering code in division 71. Division 06 is mostly the licence and operating entities themselves. If you are selling to contractors rather than operators, 09100 is the better filter.
