How to read SIC 25610
SIC 25610 reads as division 25 (manufacture of fabricated metal products, except machinery and equipment), group 256, class 2561, then the full five digits, inside section C, manufacturing. A company picks its own codes, up to four, and Companies House does not check them, so 25610 is the company's own description of what it does, and 1,076 list it first where 1,198 list it anywhere.
Who sells into division 25
The skills shortage decides who sells into this division. Engineering recruiters mine it for firms that will need welders, fabricators and machinists.

Should an engineering workshop register under 25620 machining or a division 28 machinery code?
Ask what leaves the building. If you machine components, 25620 is right, whether the parts go to aerospace, automotive or general industry. Customers may call you an engineering firm anyway. Division 28 is for companies whose finished product is a machine. Subcontract shops nearly always belong in 25. If you are unsure, list the code that matches most of your revenue. You can change it later on a confirmation statement.
