SIC 2007 reference · Companies House
UK SIC code lookup
Every UK limited company picks up to four SIC codes when it forms. Below are the 514 biggest UK SIC 2007 codes. Each one has its own guide. They are grouped the way the official list groups them. Each page shows what the code means. It shows real company counts from the Companies House register, the codes that sit near it, and how to build a prospect list from it.

What is a SIC code?
SIC stands for Standard Industrial Classification. It is a five-digit code that says what a UK company does, and every limited company has at least one. Companies House asks for it when a company incorporates, and it is the main way the register can be split by industry: without it, five million companies are just names and addresses. The UK list in force is SIC 2007, and the condensed version Companies House accepts runs to about 730 codes.
How the five digits work
The digits nest, from a whole sector down to one activity. Take 68100, buying and selling of own real estate. The first two digits, 68, are the division: real estate activities. The third makes it group 681. The fourth narrows to a class, and the fifth to the subclass, which is the level a company actually picks. Above the division sits a section, a single letter from A to U, which is the broadest tier of all. So reading a code left to right takes you from an industry to a job.
How to find a SIC code
To find a SIC code for your own company, work down the SIC code list below: pick the section that matches your industry, open its division, and choose the subclass closest to what the business actually does. To find the SIC code of an existing company, search its name on the Companies House register: the codes it filed sit on its overview page, and each of our code guides explains what the filing means in practice. The full UK SIC code list runs to about 730 condensed codes; the 514 on this page are the largest by live companies on the register.
How to search UK companies by SIC code
Companies House lets you search companies by SIC code through its advanced search, and it is free: pick the code, add a place or an incorporation date if you want, and the register returns every live company that filed it. What the register cannot give you is a way to contact them, because it holds no websites or email addresses. The practical workflow, code to contactable list, is written up step by step in our recipe for sizing a UK market by SIC code, and every code page below shows the live company count so you can judge a market before you search it.
Who chooses a company’s SIC code?
The company does. It declares its codes on incorporation and can list up to four, which is how a business that does more than one thing describes itself. Codes are changed on the annual confirmation statement, and the change takes effect as soon as it is filed. There is no approval step, and no fee.
The part that matters most for anyone using this data: Companies House does not check the choice. Nobody verifies that a company filed under 62012 writes software. A SIC code is a claim a company made about itself, not a verified fact, and it is worth reading that way.
What happens if a company picks the wrong one?
Nothing, directly. There is no penalty and no correction notice. The consequences turn up elsewhere: lenders and insurers read the code to price risk, some grants and schemes are scoped by it, and a wrong code can put a company in front of the wrong people or hide it from the right ones. It also means any list built from SIC codes carries some noise, which is why a code is a starting filter rather than the whole answer.
Why the same company appears under several codes
Because it can hold four. Every code page here shows two counts for that reason: how many companies list the code first, and how many list it in any of their four positions. The gap between those numbers tells you whether a code describes a business or just one of the things it does. A tight gap means a clean filter. A wide one means you should match on any position and narrow with something else.
