Silviculture and other forestry activities (SIC code 02100)
Silviculture and other forestry activities is UK SIC code 02100. It sits in division 02 (Forestry and logging) of the SIC 2007 list. On the August 2026 Companies House register, 2,756 active UK companies list 02100 among their SIC codes. 2,462 of them list it first. That makes it the most used code in its division.
Division 02: Forestry and logging
Forestry and logging covers woodland work across the UK: growing it, managing it and harvesting it. Companies under 02100 do silviculture. That means planting, thinning and looking after tree stock. Much of it runs on long management contracts for estates or public bodies. Code 02400 covers the support contractors around them. Their work includes timber measurement, forest fire protection and hauling logs inside the forest. Registrations cluster in Scotland and the north of England, where the commercial plantations are. Most firms here are small and owner-run.

Who prospects SIC 02100 companies
Specialist insurance brokers work this division hardest. Forestry carries chainsaw, plant and public liability risks. Generalist policies cover them badly. Equipment finance firms, safety training providers and accountants who know woodland tax also buy this data. A new incorporation usually means a contractor has left a job to go it alone. Insurance, kit finance and bookkeeping all get sorted in the same few weeks. Websites in this trade are often thin or years old. The poor-website filter picks those firms out.

SIC 02100 is a five-digit code, and the digits are not arbitrary. The first two, 02, are the division, forestry and logging. Add the third and you have group 021; 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 A, agriculture, forestry and fishing, 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 02100 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 02100 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 02100 are London (127), Derby (53), Edinburgh (45), Liverpool (41) and Glasgow (31). 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 02100 as a filter
2,756 companies is 0.05 per cent of the 5,190,464 active companies on the UK register, and ranks 02100 most used of the 3 codes we track in division 02. 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 02100
Almost everybody who uses 02100 means it: 2,462 of 2,756 companies put it first, leaving only 294 carrying it as a secondary code. That makes it an unusually clean filter. You can match on the code alone and trust that the companies you get really are in this line of work.
These companies are spread out. London is the largest single cluster at 5 per cent and the top five post towns together hold only 11 per cent, so the remaining 89 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 02100 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: 02100, registered office in London, incorporated in the last ninety days, which turns a 2,756 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 02100
How many UK companies use SIC code 02100?
2,756 active UK companies list 02100 (Silviculture and other forestry activities) among their registered SIC codes. Each company may register up to four. Of those, 2,462 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
What is the difference between 02100 and 02400 for a forestry contractor?
Use 02100 silviculture if you grow and manage the trees yourself. Use 02400 for support work done in someone else's woodland. That covers harvesting support, fire protection and in-forest timber transport. If you do both, list both codes. The choice is yours. Companies House records what you declare and checks nothing.
Does my SIC code affect the licences a forestry business needs?
No. SIC codes are statistical labels, not permissions. You apply for felling licences separately, through Forestry England, Scottish Forestry or Natural Resources Wales. Your registered code has no bearing on them. Insurers and lenders do read your SIC code to judge risk. Keeping it accurate saves awkward questions at renewal or when you apply for finance.
