How to read SIC 09900
SIC 09900 reads as division 09 (mining support service activities), group 099, class 0990, then the full five digits, inside section B, mining and quarrying. A company picks its own codes, up to four, and Companies House does not check them, so 09900 is the company's own description of what it does, and 777 list it first where 986 list it anywhere.

Which SIC code should an oil and gas contractor's limited company use?
Use 09100 if your work directly supports drilling or well operations. Most offshore contractors pick it. Engineers doing design or consultancy sometimes use an engineering code from division 71 instead. Both are fine. You declare your own code at incorporation and nobody at Companies House judges the fit. Agencies and insurers may still expect something that suits the sector.
