Division 74: Other professional, scientific and technical activities
This is the register's professional services miscellany. 74909, other professional, scientific and technical activities n.e.c., is a genuine catch-all that companies pick when nothing more specific fits, so lists built on it mix unrelated trades and need careful filtering. 74990 is different again: Companies House labels it non-trading company, and it mostly marks entities with little prospecting value. The cleaner segments are 74100 for specialised design, 74901 for environmental consulting, 74902 for quantity surveying, translation under 74300 and photography under 74201, 74202 and 74209.
Sensible prospecting here means working code by code. Designers under 74100 buy creative software, hardware and portfolio services; quantity surveyors are courted by construction firms and insurance providers; environmental consultants attract training, accreditation and tender-alert services; photographers buy kit, insurance and booking tools. Skip 74990 entirely and treat 74909 as a research pile rather than a campaign list. Across the useful codes, new incorporations combined with a no-website flag identify freelancers formalising, a good moment for accountants and insurers to introduce themselves.

What does SIC code 74990 actually mean?
On the UK register 74990 is labelled non-trading company, indicating an entity that exists but is not carrying on business, which is distinct from the dormant code 99999. It is self-declared like any SIC code. If your company starts trading, update the code on your next confirmation statement (CS01) to something descriptive; there is no approval process and you can list up to 4 codes.
My business does not fit any SIC code cleanly. Should I use 74909?
74909 exists precisely for professional and technical activities not elsewhere classified, so it is a legitimate choice when nothing else matches. Check the full condensed SIC list first, because a specific code makes your company easier for customers, lenders and directories to categorise. You can also combine codes: Companies House permits up to 4, changeable at any confirmation statement.
