Division 25: Manufacture of fabricated metal products, except machinery and equipment
This is the UK's metalworking division. The largest group of companies registers under 25990, the catch-all for fabricated metal products, followed by 25110 for structural steelwork firms making frames, balconies and architectural metalwork, and 25620 for precision machining businesses running CNC mills and lathes. Between them these codes cover most general fabricators, welders with premises and subcontract engineering shops. The division excludes machinery itself, which belongs in 28, a distinction that trips up plenty of engineering companies at registration.
The skills shortage shapes who prospects this division: engineering recruiters mine it for firms likely to need welders, fabricators and machinists, treating headcount growth and new contract wins as their trigger. Steel stockholders, consumables suppliers, machine tool dealers and calibration services work the same lists. Structural steel firms under 25110 attract construction-adjacent sellers, from estimating software to CE marking consultancies. Newly incorporated fabricators usually come from the tools, having left employment with a customer or two already lined up, and need insurance, kit finance and a basic web presence quickly.

About SIC 25990
How many UK companies use SIC code 25990?
8,733 active UK companies include 25990 (Manufacture of other fabricated metal products n.e.c.) among their up-to-four registered SIC codes, of which 7,489 list it first. Figures are from the July 2026 Companies House register snapshot, counting active companies only.
Should an engineering workshop register under 25620 machining or a division 28 machinery code?
Ask what leaves the building. If you machine components, whether for aerospace, automotive or general industry, 25620 is correct even though customers call you an engineering firm. Division 28 is for companies whose finished product is a machine. Subcontract shops almost always belong in 25. If in doubt, list the code that best matches your main revenue; it can be changed later via a confirmation statement.
Does a steel fabricator that also installs on site need a construction SIC code?
It is worth adding one. Fabrication belongs under 25110, but site erection of structural steel has its own construction code, and listing both gives an accurate picture to insurers, main contractors and prequalification schemes that check the register. Companies can hold up to four codes from any mix of divisions, declared at incorporation or amended via the CS01 confirmation statement.
