UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.

The Known Consignor Scheme is voluntary. There is no legal requirement for any air cargo to be dispatched from the shipper as SPX (Secure) cargo; insecure cargo may still be shipped, although it will be subject to additional security measures before it can be allowed to fly.

On approval, Known Consignors are permitted (provided they comply with the requirements outlined in the regulations) to ship cargo from source. Such cargo may be transported by air without the need for any further security measures being applied.
