London is the largest cluster at 10 per cent and the top five post towns hold 20 per cent, so the other 80 per cent sit across the rest of the country. A regional filter narrows the list without gutting it.
A worked example: 03210, registered office in London, incorporated in the last ninety days, from a pool of 553. 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 03210
SIC 03210 reads as division 03 (fishing and aquaculture), group 032, class 0321, then the full five digits, inside section A, agriculture, forestry and fishing. A company picks its own codes, up to four, and Companies House does not check them, so 03210 is the company's own description of what it does, and 490 list it first where 553 list it anywhere.
Who sells into division 03
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.
About SIC 03210
How many UK companies use SIC code 03210?
553 active UK companies list 03210 (Marine aquaculture) among their registered SIC codes. Each company may register up to four. Of those, 490 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.
