Stone, concrete, ceramics and glass. The largest code is 23700, cutting, shaping and finishing of stone, which covers stonemasons and the memorial and worktop trades. Concrete products for construction, 23610, and ceramic household articles, 23410, follow. The division has twenty-four codes in the catalogue and only three of any size, so it is one of the more fragmented parts of manufacturing on the public record.

Who prospects SIC 23610 companies
This is a construction-adjacent division and most of its buyers are the same: plant and tooling suppliers, aggregate and raw material merchants, haulage, and the insurers who cover heavy machinery. Stonemasons in particular are a distinct market with their own suppliers of CNC saws, diamond tooling and slab stock. The trade is geographically anchored because the material is heavy, so regional filtering works better here than in most divisions.
Lead generation for trades & construction →How to read SIC 23610
SIC 23610 is a five-digit code, and the digits are not arbitrary. The first two, 23, are the division, manufacture of other non-metallic mineral products. Add the third and you have group 236; 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 C, manufacturing, 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 23610 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 23610 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 23610 are London (65), Birmingham (14), Bristol (10), Nottingham (9) and Doncaster (8). 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 23610 as a filter
702 companies is 0.01 per cent of the 5,190,464 active companies on the UK register, and ranks 23610 second most used of the 3 codes we track in division 23. 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 23610
Almost everybody who uses 23610 means it: 643 of 702 companies put it first, leaving only 59 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 9 per cent and the top five post towns together hold only 15 per cent, so the remaining 85 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 23610 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: 23610, registered office in London, incorporated in the last ninety days, which turns a 702 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 23610
How many UK companies use SIC code 23610?

Are kitchen worktop fitters in 23700?
Often, yes, if they cut and finish the stone themselves. 23700 covers cutting, shaping and finishing, which is what a worktop fabricator does. A business that only installs pre-made tops fits better in a division 43 construction code. Plenty of firms do both and list one of each.
Where is glass manufacturing in this division?
In the 23100 range, manufacture of glass and glass products, though the UK company counts there sit below the threshold for a dedicated page. Companies working in glazing rather than making glass belong in 43342, glazing, which is a construction code and a much larger population.
