UK Drone Regulations and Compliance
Operating drones for surveying in the UK is subject to regulations set by the Civil Aviation Authority (CAA). Key requirements include:
- Registration: Commercial drones used for surveying need to be registered with the CAA, and this registration needs to be renewed annually. (ProHort Ltd)
- Flyer ID: Anyone intending to fly a drone weighing 250g or more needs to pass a free online test and get a flyer ID from the CAA. (Survey Air, 2023)
- Operator ID: The person responsible for the UAV must register as an operator to get an operator ID, which costs £9. (Coptrz, 2024)
- Visual Line of Sight (VLOS): Drones must be flown within VLOS, typically accepted to a maximum distance of 500m horizontally and 400ft vertically from the pilot. (RICS, 2014)
- Certificates of Competency: Pilots need to obtain an A2 Certificate of Competency (A2 CofC) and/or a General Visual Line of Sight Certificate (GVC). (Coptrz, 2024)
- Airspace Restrictions: Before flying a drone, it is essential to check for any airspace restrictions, including prohibited areas, restricted areas, and danger areas. (Survey Air, 2023)
- Height Restrictions: Drones should never be flown more than 120m (400ft) above the surface. (Survey Air, 2023)
- Flight Restriction Zones (FRZ): Drones should never be flown in an airport’s flight restriction zone (FRZ) without permission. (Survey Air, 2023)
- Categories of Operations: Drone operations are divided into three categories based on risk: Open, Specific, and Certified. (Coptrz, 2024)
