How to Register a DJI Phantom 4 Pro V2 in the UK

The Phantom 4 Pro V2 in 2026

DJI discontinued the Phantom 4 Pro V2 several years ago, yet thousands of UK pilots continue to fly it regularly. Its one-inch 20-megapixel sensor, 4K/60fps video capability, and mechanical shutter made it an industry standard for aerial photography, mapping, and surveying. In 2026, it remains a capable and reliable aircraft — but replacement parts and batteries are becoming increasingly difficult to source.

From a regulatory standpoint, the Phantom 4 Pro V2 is treated identically to any other drone above 250g without a class marking. The fact that it is discontinued does not alter your registration obligations or flying privileges in any way.

Registration Requirements

Because the Phantom 4 Pro V2 exceeds 250g and carries a camera, both forms of CAA registration are mandatory:

1. Flyer ID: Pass the CAA online theory test (free). This covers fundamental airspace knowledge, privacy rules, and safety principles. Valid for five years.
2. Operator ID: Register as a drone operator and pay £10.33 per year. You receive a unique code that must be displayed on your aircraft.
3. Label the drone: Attach your Operator ID to the body of the Phantom 4 Pro V2 or place it inside the battery compartment where it is visible when the battery is removed.

If multiple people fly the same Phantom, each pilot needs their own Flyer ID, but one Operator ID covers the aircraft itself.

Where You Can Fly

As a legacy drone weighing 1,375g, the Phantom 4 Pro V2 operates under the Open A3 subcategory during the transitional period. This imposes the following constraints:

• 150-metre buffer: You must maintain at least 150 metres horizontal distance from residential, commercial, industrial, and recreational areas.
• Visual line of sight (VLOS): Keep the drone within unaided visual contact at all times.
• 120-metre altitude limit: Never exceed 120 metres (400 feet) above ground level.
• No flight over uninvolved people: The A3 subcategory does not permit flights directly above people who are not part of your operation.

If you need to fly closer to people or in built-up areas — for example, real estate photography in a residential neighbourhood — you will need to apply for a Specific Category Operational Authorisation from the CAA.

Buying Second-Hand — What to Check

The Phantom 4 Pro V2 is widely available on the second-hand market. If you are purchasing a used unit, keep the following in mind:

• Battery condition: Lithium polymer batteries degrade over time. Check charge cycles and look for swelling. Replacement batteries are becoming scarce and expensive.
• Firmware updates: Ensure the drone runs the latest DJI firmware. Older firmware versions may lack up-to-date geofencing data for UK airspace.
• Propeller guards: While not mandatory in A3 (because you fly far from people), having propeller guards available is useful if you later obtain an OA for closer operations.
• Spare parts: DJI no longer manufactures Phantom 4 Pro V2 components. Third-party parts exist but vary in quality. Factor in long-term maintenance costs before purchasing.

Mapping and Survey Use

Many UK professionals still use the Phantom 4 Pro V2 for photogrammetry, topographic surveying, and agricultural mapping. Its mechanical shutter eliminates rolling shutter distortion, making it more accurate than many newer consumer drones for mapping workflows.

If you use the Phantom for commercial mapping, you will likely need an Operational Authorisation under the Specific Category, as survey flights often take place over farmland near residential properties or infrastructure. Your operations manual must document standard operating procedures, emergency protocols, and maintenance schedules.

Summary for Phantom 4 Pro V2 Owners

• At 1,375g, Flyer ID + Operator ID registration is mandatory.
• Flies under Open A3 as a legacy drone — 150m from built-up areas, 120m altitude, VLOS only.
• Discontinued but still legal. No class mark means transitional rules apply.
• Second-hand buyers should check battery health and spare parts availability.
• Commercial mapping and survey work typically requires a Specific Category OA.
• Insurance is not legally required for recreational flights but is strongly recommended given the drone's weight.
