DJI Mini 4 Pro UK Rules — Complete Flying Guide
Quick Answer
The DJI Mini 4 Pro weighs 249g, placing it in the sub-250g category. You still need a Flyer ID (free, renewed annually). An Operator ID (£10.33/year) is not required for purely personal recreational flying, but is needed if you fly commercially or carry a camera used for non-personal purposes. You can fly over uninvolved people under Open Category A1 but must stay clear of crowds.
Registration and ID Requirements
Even though the Mini 4 Pro sits below the 250g threshold, registration is still partially required:
- Flyer ID — mandatory for all drone pilots regardless of drone weight. Pass the free online theory test at register-drones.caa.co.uk and renew every year
- Operator ID — not required if you fly purely for personal recreation. Required if you use footage commercially, provide drone services, or if the drone is equipped with a camera used for non-personal purposes. Costs £10.33 per year
If in doubt about whether your flying counts as personal, the safest approach is to register for both. The Operator ID must be displayed on the aircraft when required.
Altitude, Distance, and Airspace Rules
The following rules apply to all DJI Mini 4 Pro flights in the UK:
- Maximum altitude: 120 metres (400 feet) above ground level
- Visual Line of Sight (VLOS): you must be able to see the drone at all times without binoculars or other aids
- Flight Restriction Zones (FRZs): never fly within an FRZ without explicit permission. Check the CAA Drone Safety Map or NATS Drone Assist app before every flight
- No-fly areas: airports (automatic FRZs), military installations, prisons, and other restricted zones
- Uninvolved people: you may fly over uninvolved people under A1 rules, but you must never intentionally fly over crowds or gatherings
Night Flying
Night flying with the DJI Mini 4 Pro is permitted in the UK provided the drone is equipped with lights that are visible to the pilot at all times. The Mini 4 Pro does not have built-in anti-collision lights sufficient for night flight — you may need to attach a lightweight strobe or beacon.
All other standard rules apply at night, including VLOS, altitude limits, and FRZ restrictions. Be especially cautious about maintaining visual contact in low-light conditions.
Privacy and Data Protection
The DJI Mini 4 Pro has a high-quality camera capable of capturing detailed footage. UK privacy law applies to drone operators:
- The Data Protection Act 2018 and UK GDPR apply whenever you record identifiable individuals
- Avoid filming people without their knowledge or consent, especially in private settings such as gardens and homes
- Recording in public spaces is generally permitted, but publishing footage that identifies individuals may require a lawful basis under data protection law
- If someone asks you to stop filming them, it is good practice to comply
- Persistent or intrusive drone surveillance could constitute harassment under the Protection from Harassment Act 1997
Where You Cannot Fly
Even with the sub-250g advantage, certain locations remain off-limits or heavily restricted:
- Airport FRZs — extending several kilometres around airports. The penalty for flying in an airport FRZ without permission can include prosecution
- Military sites — prohibited airspace is marked on aviation charts and the CAA Drone Safety Map
- Prisons — it is a criminal offence to fly a drone near a prison under the Prisons (Interference) Act 2018
- National Trust / English Heritage sites — many prohibit drone flying on their land. Check individual site policies
- Congested areas — while the sub-250g classification gives you more flexibility, exercise caution in built-up areas and always respect local bylaws
