How to read SIC 51101
SIC 51101 reads as division 51 (air transport), group 511, class 5110, then the full five digits, inside section H, transportation and storage. A company picks its own codes, up to four, and Companies House does not check them, so 51101 is the company's own description of what it does, and 577 list it first where 659 list it anywhere.

Selling here is niche and high value. Aviation insurers and their brokers want these relationships.

Should a drone operator register under 51210?
Usually not. Code 51210 is for transporting freight by air, so it only fits drone firms that actually carry cargo. Aerial photography and filming companies normally register 74202. Drone survey and inspection work sits better under engineering or other professional codes. SIC codes are self-selected and unchecked. Even so, an airline code on a photography drone business will confuse insurers and banks.
