UK SIC 2007 · 26511
Manufacture of electronic measuring, testing etc. equipment, not for industrial process control (SIC code 26511)
Manufacture of electronic measuring, testing etc. equipment, not for industrial process control is UK SIC code 26511. It sits in division 26 (Manufacture of computer, electronic and optical products) of the SIC 2007 list. On the August 2026 Companies House register, 1,493 active UK companies list 26511 among their SIC codes. 1,315 of them list it first. That makes it the third most used code in its division.
The largest of the newly covered divisions and the most varied. Consumer electronics, 26400, and electronic components, 26110, lead it, followed by two measurement and control codes, 26511 and 26512, and computer manufacture at 26200. This is where UK electronics design and low-volume manufacture actually lives, and a good deal of it is small engineering-led firms rather than factories.
Who prospects SIC 26511 companies
Component distributors, contract electronics manufacturers, PCB fabricators and test equipment suppliers sell into this division constantly. Specialist recruiters do too, because embedded and RF engineering skills are scarce. The instrumentation codes, 26511 and 26512, are worth separating from the rest: those companies sell into industrial process and laboratory markets and buy very differently from a consumer electronics business. Cambridge and the Thames Valley are disproportionately represented.

SIC 26511 is a five-digit code, and the digits are not arbitrary. The first two, 26, are the division, manufacture of computer, electronic and optical products. Add the third and you have group 265; 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 26511 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 26511 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 26511 are London (191), Cambridge (39), Manchester (22), Bristol (20) and Leicester (19). 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 26511 as a filter
1,493 companies is 0.03 per cent of the 5,190,464 active companies on the UK register, and ranks 26511 third most used of the 5 codes we track in division 26. 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 26511
Almost everybody who uses 26511 means it: 1,315 of 1,493 companies put it first, leaving only 178 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 13 per cent and the top five post towns together hold only 19 per cent, so the remaining 81 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 26511 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: 26511, registered office in London, incorporated in the last ninety days, which turns a 1,493 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 26511
How many UK companies use SIC code 26511?
1,493 active UK companies list 26511 (Manufacture of electronic measuring, testing etc. equipment, not for industrial process control) among their registered SIC codes. Each company may register up to four. Of those, 1,315 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Is a company that designs but does not manufacture electronics in division 26?
Frequently yes, and that is a known blur in the classification. A fabless design house often files a division 26 code because that is where its product sits, even though the physical work is contracted out. Some use 71129 engineering design instead. Match on any SIC position and expect both.
What is the difference between 26511 and 26512?
26511 is measuring and testing equipment that is not for industrial process control, so laboratory and general instrumentation. 26512 is specifically industrial process control equipment. The buyers are genuinely different: one sells into labs and R and D, the other into plant and factory automation.
