Division 51: Air transport
Air transport is a small but distinctive division reserved for companies that carry passengers or freight by air. The code most often seen on the UK register is 51210, freight air transport, covering cargo airlines, charter operators and businesses flying goods under their own air operator certificate. Passenger carriage, scheduled or charter, has separate codes within the division. The defining test is operating aircraft for transport: brokers, handlers and travel businesses that arrange flights without flying them are classified elsewhere, which keeps this division genuinely airline-shaped despite its modest size.
Prospecting here is niche and high value. Aviation insurers and their brokers, aircraft finance and leasing specialists, MRO providers, fuel suppliers and ground handling companies all want relationships with operators, and the pool is small enough that complete coverage is achievable. Recruiters placing pilots, engineers and operations staff use these codes too. A new incorporation in division 51 tends to precede regulatory approvals and aircraft acquisition, an expensive and advice-hungry phase, so early contact matters far more than volume in this market.

About SIC 51210
How many UK companies use SIC code 51210?

Should a drone operator register under 51210?
Usually not. 51210 is meant for transporting freight by air, so it only fits drone businesses actually carrying cargo. Aerial photography and filming companies normally register 74202, and drone survey or inspection work sits better under engineering or other professional activity codes. SIC codes are self-selected and unchecked, but choosing an airline code for a photography drone business will confuse insurers and banks.
Does an air freight broker or cargo agent belong in division 51?
No. Division 51 is for the carriers themselves. Agents, brokers and general sales agents who sell or arrange air cargo capacity on other operators' aircraft register in division 52, typically under 52290. A company holding both an air operator certificate and a brokerage arm can list codes from both divisions, since Companies House permits up to four.
