Division 14: Manufacture of wearing apparel
Businesses here make clothing and accessories. They do not just sell them. Most UK registrations sit under 14190, other wearing apparel and accessories. It is a broad code. It holds independent fashion labels, childrenswear brands and makers of hats, scarves and sportswear. Some of these firms run their own studios and small production units. Many others design in the UK and have the garments made abroad. They still call themselves apparel manufacturers, because the product is theirs.
Who prospects SIC 14120 companies
Marketing agencies work this division hard. Young clothing brands live or die on audience. That means social, influencer work and paid ads. Ecommerce developers, product photographers and fulfilment providers chase the same names. The best signal is a recent incorporation whose website is clearly unfinished. That founder is mid-launch and picking every supplier at once. The poor-website filter surfaces exactly those brands. For older labels, growth signals point to budget for a rebrand, wholesale outreach and international shipping help.
Lead generation for agency owners →How to read SIC 14120
SIC 14120 is a five-digit code, and the digits are not arbitrary. The first two, 14, are the division, manufacture of wearing apparel. Add the third and you have group 141; 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 14120 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 14120 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 14120 are London (106), Manchester (18), Birmingham (17), Leicester (8) and Nottingham (6). 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 14120 as a filter
645 companies is 0.01 per cent of the 5,190,464 active companies on the UK register, and ranks 14120 4th most used of the 5 codes we track in division 14. 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 14120
Almost everybody who uses 14120 means it: 595 of 645 companies put it first, leaving only 50 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 16 per cent and the top five post towns together hold only 24 per cent, so the remaining 76 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 14120 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: 14120, registered office in London, incorporated in the last ninety days, which turns a 645 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 14120
How many UK companies use SIC code 14120?
645 active UK companies list 14120 (Manufacture of workwear) among their registered SIC codes. Each company may register up to four. Of those, 595 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
I design clothes in the UK but production happens overseas. Is 14190 still the right code?
Yes, and it is common practice. Your company owns the designs and sells the finished garments as its own product. Classing that as apparel manufacture is fair, even when someone else does the sewing. Some brands prefer a wholesale or online retail code. Neither choice carries a penalty. You pick your own codes and can revise them on any confirmation statement.
Can a clothing brand list both a manufacturing and a retail SIC code?
Yes. Companies House allows up to four SIC codes per company. There is no rule against mixing divisions. Direct-to-consumer labels often pair 14190 with an online retail code such as 47910. You declare codes at incorporation on the IN01 form. You update them through the confirmation statement. No approval process is involved.
