UK SIC 2007 · 45200
Maintenance and repair of motor vehicles (SIC code 45200)
Maintenance and repair of motor vehicles is UK SIC code 45200. It sits in division 45 (Wholesale and retail trade and repair of motor vehicles and motorcycles) of the SIC 2007 list. On the August 2026 Companies House register, 57,505 active UK companies list 45200 among their SIC codes. 47,552 of them list it first. That makes it the most used code in its division.
Division 45 holds everything to do with selling, servicing and repairing motor vehicles and motorcycles. The SIC system keeps it apart from general retail and wholesale. Independent garages under 45200 are the biggest block. Used car dealers on 45112 come next. Parts businesses split by channel: 45320 for retail counters and web shops, 45310 for trade wholesale. Franchised new car dealerships use 45111. Vans, trucks and other vehicles use 45190. Code 45400 wraps the whole motorcycle trade into one: sales, servicing and parts together.
Who prospects SIC 45200 companies
The motor trade is a staple market for insurance brokers. They need a steady flow of garages and dealers to quote for motor trade combined policies. Warranty administrators, parts distributors, MOT equipment suppliers and vehicle finance houses work it too. So do accountants who understand stocking loans. A new incorporation usually means premises, equipment and cover are all being arranged at once. Weak websites are still common among independent garages, and the poor-website filter hands local marketing firms an easy first conversation.
Lead generation for accountants & bookkeepers →How to read SIC 45200
SIC 45200 is a five-digit code, and the digits are not arbitrary. The first two, 45, are the division, wholesale and retail trade and repair of motor vehicles and motorcycles. Add the third and you have group 452; 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 G, wholesale and retail trade, 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 45200 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 45200 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 45200 are London (3,879), Birmingham (1,307), Manchester (900), Glasgow (754) and Leicester (695). 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 45200 as a filter
57,505 companies is 1.1 per cent of the 5,190,464 active companies on the UK register, and ranks 45200 most used of the 7 codes we track in division 45. 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 45200
47,552 companies put 45200 first and a further 9,953, 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 7 per cent and the top five post towns together hold only 13 per cent, so the remaining 87 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 45200 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: 45200, registered office in London, incorporated in the last ninety days, which turns a 57,505 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 45200
How many UK companies use SIC code 45200?
57,505 active UK companies list 45200 (Maintenance and repair of motor vehicles) among their registered SIC codes. Each company may register up to four. Of those, 47,552 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Should a used car dealer that also runs a workshop register 45112 or 45200?
Use both. Companies House lets a company hold up to four SIC codes. Listing 45112 for vehicle sales next to 45200 for repair work is normal practice. You choose the codes yourself at incorporation. You can update them on your next confirmation statement (CS01). There is no approval process to pass.
Which code fits a business selling car parts online?
Retail of motor vehicle parts and accessories is 45320, whatever the channel. So an online parts shop belongs there, not under 47910 general internet retail. Vehicle parts are deliberately kept inside division 45. If the same company also sells unrelated goods online, it can add 47910 as a second code.
