How to read SIC 84120
SIC 84120 reads as division 84 (public administration and defence; compulsory social security), group 841, class 8412, then the full five digits, inside section O, public administration and defence. A company picks its own codes, up to four, and Companies House does not check them, so 84120 is the company's own description of what it does, and 4,658 list it first where 5,699 list it anywhere.
Who sells into division 84
Selling into this division is niche, but not pointless. Fire safety consultancies and training providers under 84250 buy certification, equipment and e-learning platforms.
About SIC 84120
How many UK companies use SIC code 84120?
5,699 active UK companies list 84120 (Regulation of health care, education, cultural and other social services, not incl. social security) among their registered SIC codes. Each company may register up to four. Of those, 4,658 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Why do private companies appear under public administration SIC codes?
SIC codes are self-selected and nobody gatekeeps them. Any director can pick a division 84 code at incorporation or on a confirmation statement (CS01). Some picks are deliberate, such as a fire risk assessment firm choosing 84250. Others are simple misreadings of the code description. Real government departments and most councils are not Companies House entities. So this division is mainly private and third-sector organisations.
