Division 16: Manufacture of wood and of products of wood and cork, except furniture; manufacture of articles of straw and plaiting materials
Despite its sprawling official title, this division in the UK is mostly about joinery workshops. The dominant registration is 16230, other builders' carpentry and joinery, used by firms that manufacture staircases, doors, window frames, roof trusses and bespoke timber components for the building trade. The division also takes in sawmilling and timber treatment businesses, though these are far less numerous. What distinguishes 16230 from the installation codes in division 43 is the workshop: these companies make the product before anyone fits it.
Because joinery manufacturers sell almost exclusively into construction, the firms that prospect them mirror the building supply chain: timber merchants, machinery dealers, CNC tooling suppliers and trade credit insurers. Builders and fit-out contractors also use this data in reverse, sourcing local workshops for bespoke work. New incorporations frequently mark an experienced joiner setting up alone, a prime moment for equipment finance and workshop insurance. Companies without a website are common and tend to depend on trade relationships, so direct outreach works better than search advertising for reaching them.

About SIC 16230
How many UK companies use SIC code 16230?
8,095 active UK companies include 16230 (Manufacture of other builders' carpentry and joinery) among their up-to-four registered SIC codes, of which 7,983 list it first. Figures are from the July 2026 Companies House register snapshot, counting active companies only.
Should a joinery business choose 16230 or 43320?
Use 16230 if you manufacture joinery in a workshop, such as staircases, doors or trusses, whether or not you also fit them. Use 43320, joinery installation, if your work is fitting products made by others on site. Businesses that genuinely do both can list both codes. The distinction matters mainly for how prospectors and insurers read your company, since Companies House itself never queries the choice.
How does a company change its SIC code if the business shifts from site work to manufacturing?
File your next confirmation statement (form CS01) with the updated codes; the change appears on the public register as soon as it is accepted. There is no separate application, no supporting evidence required and no approval decision. You can also add codes rather than replace them, up to a maximum of four, which suits businesses transitioning gradually between activities.
