How to Register a DJI Matrice 300 RTK in the UK

DJI Matrice 300 RTK Specifications

The DJI Matrice 300 RTK is an enterprise-grade survey and inspection drone. Although it has been succeeded by the Matrice 350 RTK, many operators across the UK continue to fly the M300 RTK for infrastructure inspection, mapping, and search-and-rescue operations.

Registration Requirements

Because the Matrice 300 RTK exceeds 250g, you must complete two registrations with the Civil Aviation Authority (CAA):

• Flyer ID — required for every person who flies the drone. You must pass an online theory test covering UK airspace rules, safety procedures, and privacy obligations. The test is free and must be renewed annually.
• Operator ID — required for the person or organisation responsible for the drone. Costs £10.33 per year. Your Operator ID must be displayed on the aircraft.

Register for both at the CAA drone registration service at register-drones.caa.co.uk.

Specific Category Operations

At over 4 kg MTOM without a class marking, the Matrice 300 RTK cannot fly under the standard Open Category rules. Most operations will require Specific Category authorisation from the CAA.

What This Means in Practice

• You must prepare an Operational Authorisation (OA) application, which includes a detailed risk assessment
• A SORA (Specific Operations Risk Assessment) or an established STS (Standard Scenario) may apply depending on your operation type
• Pilots typically need a GVC (General VLOS Certificate) or equivalent recognised qualification
• You must maintain an Operations Manual documenting your procedures, maintenance schedules, and emergency protocols

Processing times for Operational Authorisations vary. Submit your application well in advance of any planned survey or inspection work.

Insurance Requirements

Third-party liability insurance is mandatory for all commercial operations under EC Regulation 785/2004, which continues to apply in the UK. For an enterprise drone such as the Matrice 300 RTK, you should consider:

• Third-party liability cover — a minimum of £750,000, though most commercial policies offer £1 million or more
• Hull insurance — the M300 RTK represents a significant investment; hull cover protects against accidental damage, theft, and loss
• Public liability — especially important for operations near infrastructure, buildings, or people

UK specialist providers include Coverdrone, Flock (pay-as-you-fly), and Moonrock Insurance. Confirm that your policy covers the specific weight class and operation type.

Practical Tips for M300 RTK Operators

• Always check airspace before every flight using the CAA Drone Safety Map or NATS Drone Assist app
• Maintain VLOS (Visual Line of Sight) unless you hold a specific BVLOS authorisation
• Maximum altitude is 120 metres (400 feet) above ground level in most cases
• Keep firmware updated — DJI regularly releases geofencing and safety updates
• Log every flight — record date, location, duration, and any incidents. This is a requirement under most Operational Authorisations
• Display your Operator ID — it must be visible on the aircraft at all times

Key Regulatory References

All UK drone regulations are set and enforced by the Civil Aviation Authority (CAA). The primary legislation is the Air Navigation Order 2016 (as amended) and UK Regulation (EU) 2019/947 retained in UK law. For the latest rules, always refer to the official CAA website at caa.co.uk.

The Matrice 300 RTK is a legacy drone — it does not carry a class marking under the current UK/EU classification system. Operators should stay informed about any transitional period changes that may affect legacy aircraft operations.
