UK drone rules: Flyer ID, Operator ID and sub-250g drones
Understand current UK drone rules for Flyer IDs, Operator IDs and sub-250g camera drones, including class marks, flight limits and Remote ID.
The short version: In the UK, a camera drone weighing 100g to under 250g needs both a Flyer ID for the pilot and an Operator ID for the person responsible for it. Being under 250g gives useful flying permissions, but it does not remove registration, airspace or safety rules. Check the aircraft’s class mark and actual configuration before flying.
Which ID you need
These are the CAA’s Open category rules, checked on 1 November 2026, for flying outdoors.
A Flyer ID shows you have passed the theory test. An Operator ID identifies the person or organisation responsible for managing the aircraft.
The CAA registration guidance sets these weight thresholds:
- Under 100g: neither ID is mandatory.
- 100g to under 250g, without a camera: Flyer ID required; Operator ID optional.
- 100g to under 250g, with a camera: both required.
- 250g to under 25kg: both required.
The operator must be at least 18. Label the drone with the Operator ID, not the Flyer ID. The CAA explains these roles in its legal requirements guide.
What sub-250g means for a Mini 4 Pro
DJI lists the Mini 4 Pro’s standard take-off weight as under 249g, including its standard Intelligent Flight Battery, propellers and a microSD card.
That makes it a useful small-camera-drone example, but check the actual aircraft. Accessories, modifications and battery choice can change the relevant weight or compliance.
DJI specifically says the Intelligent Flight Battery Plus takes the aircraft above 249g. Do not assume an imported battery or added accessory preserves the standard configuration’s permissions.
A standard Mini 4 Pro is above 100g and has a camera, so the current rules require both IDs.
How class marks affect flying permissions
A class mark describes the aircraft’s compliance category. It is separate from your registration IDs.
UK0 and European C0 aircraft can use the A1 sub-category. Legacy aircraft without either class mark can also use A1 when below 250g.
Under the CAA’s class-mark guidance, European C marks are treated as the corresponding UK class until 31 December 2027. From 1 January 2028, European C-marked aircraft become legacy aircraft and their weight determines the appropriate Open sub-category.
Check the mark on your own aircraft. A model name or shop description does not establish which label your unit carries.
Flying near people and buildings
An eligible sub-250g aircraft in A1 can fly closer than 50m to uninvolved people and can fly over individuals safely. You must never fly over crowds.
A crowd is not defined by a fixed headcount. The practical issue is whether people can move away because of how closely they are gathered.
Eligible small drones can fly in residential, recreational, commercial and industrial areas. This does not give permission to take off from any property or disregard privacy. Check the CAA’s A1 overview before planning the location.
Height, visibility and restricted airspace
Keep the aircraft in direct sight with a view of the surrounding airspace. A controller screen or advertised transmission range does not replace that requirement.
The normal height limit is 120m from the closest point of the earth’s surface. Over hills or cliffs, that may differ from the height shown relative to take-off.
Airport Flight Restriction Zones require the relevant permission. Check current restrictions, temporary notices and local hazards before every flight. The CAA’s location rules warn that built-in drone software may not be up to date.
When Remote ID becomes mandatory
Remote ID broadcasts identification and location information. It is separate from sticking an Operator ID label on the aircraft.
For Open category operations, the CAA’s current timetable makes it mandatory from 1 January 2028 for UK0 aircraft weighing at least 100g with a camera, and legacy aircraft in that weight-and-camera group.
Other classes have earlier dates. Use the CAA Remote ID table and the manufacturer’s instructions for your aircraft.
Before your next flight
Check your IDs, label, class mark and ready-to-fly configuration. Confirm landowner permission for take-off and landing, airspace restrictions, weather and a clear landing area.
Plan a short route that stays within direct sight. Keep clear of crowds, wildlife and emergency activity. If the flight is commercial, check the CAA’s third-party insurance requirement as well.
