Everyone knows the big vehicle plants. The grassroots of this division are component makers. UK registrations pile into 29320, manufacture of other parts and accessories for motor vehicles. That code holds suppliers of interior trim, brackets and wiring harnesses. It also holds performance and tuning parts firms, and the aftermarket specialists who make components for classic and modified cars. Trailer and semi-trailer builders sit in this division too, along with coachwork and conversion firms such as campervan builders. Most companies here are small suppliers, not assemblers.
Who prospects SIC 29320 companies
Parts makers ship all day, to production lines, distributors and online buyers. That is why logistics providers and pallet networks chase this division for freight contracts. Recruiters supplying production staff follow, as do quality consultants working to automotive standards and tooling suppliers. The signals split by segment. For aftermarket brands, a fresh incorporation plus a weak website points to a launch in progress, and the poor-website filter finds them. For tier suppliers, growth and new filings hint at contract wins. Those wins ripple into haulage, packaging and staffing. Electric vehicle supply chains keep adding new entrants worth watching.
Lead generation for wholesalers & suppliers →How to read SIC 29320
SIC 29320 is a five-digit code, and the digits are not arbitrary. The first two, 29, are the division, manufacture of motor vehicles, trailers and semi-trailers. Add the third and you have group 293; 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 29320 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 29320 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 29320 are London (267), Cambridge (240), Birmingham (45), Coventry (41) and Northampton (28). 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 29320 as a filter
2,553 companies is 0.05 per cent of the 5,190,464 active companies on the UK register, and ranks 29320 most used of the 4 codes we track in division 29. 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 29320
2,127 companies put 29320 first and a further 426, 17 per cent, list it in one of their other three SIC slots. That gap is the difference between a tight list and a broad one. First-code-only is the safer filter when you are writing to them; matching any position is worth it when you need the volume.
These companies are spread out. London is the largest single cluster at 10 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 29320 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: 29320, registered office in London, incorporated in the last ninety days, which turns a 2,553 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 29320
How many UK companies use SIC code 29320?
2,553 active UK companies list 29320 (Manufacture of other parts and accessories for motor vehicles) among their registered SIC codes. Each company may register up to four. Of those, 2,127 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Should a campervan or vehicle conversion business register in division 29?
Usually yes. Coachbuilding and body conversion has its own codes inside division 29, and those fit campervan converters. Specialist parts fabrication fits 29320. Some converters pick a motor trade code from division 45 instead, especially when selling the finished vehicles is the main business. All of these are legitimate. You declare the code yourself and can adjust it on a confirmation statement.
Do parts suppliers need different SIC codes for manufacturing and selling parts?
If you make and sell parts, list 29320 next to a division 45 sales code. That shows the full picture, and a company may hold up to four codes. If you only distribute parts made by others, skip division 29 and use the motor trade wholesale or retail codes. You choose codes at incorporation and revise them on the CS01 confirmation statement. There is no approval process.
