UK SIC 2007 · 03110
Marine fishing (SIC code 03110)
Marine fishing is UK SIC code 03110. It sits in division 03 (Fishing and aquaculture) of the SIC 2007 list. On the August 2026 Companies House register, 2,240 active UK companies list 03110 among their SIC codes. 2,221 of them list it first. That makes it the most used code in its division.
Division 03: Fishing and aquaculture
This division covers catching fish and growing them. Marine fishing, 03110, is the bulk of it and is overwhelmingly owner-operated: a boat, a skipper and a limited company formed around the two. Freshwater fishing sits in 03120, and 03210 covers marine aquaculture, which in the UK means salmon and shellfish farms concentrated on the Scottish coast. Almost every company here files its code in first position, which makes the division an unusually clean filter by manufacturing standards.

Who prospects SIC 03110 companies
Marine insurance brokers and vessel finance firms work this division hardest, because a boat is the single largest asset most of these businesses will ever buy. Fuel suppliers, gear and net merchants, cold chain and processing buyers all sell here too. A recent incorporation usually means a deckhand has bought their own boat, and the insurance, the finance and the catch buyer are all chosen in the same few weeks. Accountants who understand the tonnage and quota rules are scarce, which makes them worth finding.

SIC 03110 is a five-digit code, and the digits are not arbitrary. The first two, 03, are the division, fishing and aquaculture. Add the third and you have group 031; 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 03110 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 03110 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 03110 are Fraserburgh (219), Peterhead (148), Shetland (95), Banff (58) and London (55). 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 03110 as a filter
2,240 companies is 0.04 per cent of the 5,190,464 active companies on the UK register, and ranks 03110 most used of the 3 codes we track in division 03. 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 03110
Almost everybody who uses 03110 means it: 2,221 of 2,240 companies put it first, leaving only 19 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. Fraserburgh is the largest single cluster at 10 per cent and the top five post towns together hold only 26 per cent, so the remaining 74 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 03110 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: 03110, registered office in Fraserburgh, incorporated in the last ninety days, which turns a 2,240 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 03110
How many UK companies use SIC code 03110?
2,240 active UK companies list 03110 (Marine fishing) among their registered SIC codes. Each company may register up to four. Of those, 2,221 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Does a fishing company's SIC code affect its quota or licence?
No. SIC codes are statistical labels and carry no permissions. Quota and vessel licensing are handled by the Marine Management Organisation and its devolved equivalents, entirely separately from Companies House. Your registered code does not appear in that process. Insurers and lenders do read it, so keeping it accurate saves questions at renewal.
Should a shellfish farm use 03210 or a food manufacturing code?
Use 03210 marine aquaculture if you are growing the stock. If you mainly buy in and process, a division 10 food code fits better. Businesses that do both should list both, since a company may hold up to four codes. Companies House does not check the choice and you can change it on any confirmation statement.
