Best Sub-250g Drones in the UK for 2026

Why the 250g Threshold Matters in UK Drone Law

The 250g line is one of the most significant boundaries in UK drone regulation. Under the Air Navigation Order 2016 (as amended) and the CAA implementation of the UK UAS regulatory framework, drones with a maximum take-off mass (MTOM) below 250g face fewer restrictions than heavier aircraft.

For recreational pilots, a sub-250g drone without a camera means you only need a Flyer ID from the CAA. If your sub-250g drone has a camera, you also need an Operator ID and must label your drone with it. These requirements come from Article 16 of the retained EU Regulation 2019/947 as applied in the UK.

However, sub-250g does not mean unregulated. You must still follow the Drone and Model Aircraft Code (also known as the Drone Code), maintain visual line of sight, and comply with all airspace restrictions. The 250g weight class simply determines which operational category and subcategory your flights fall into.

C0 Class Marking: The Critical Distinction

Not all sub-250g drones are treated equally. The key differentiator is whether the drone carries a C0 class marking under the UK UAS regulatory framework.

A drone with a verified C0 class marking can operate in the A1 subcategory of the Open category. This means it can be flown over uninvolved people, provided the pilot does not intentionally fly over assemblies of people. This is the most permissive operational environment available without additional certification.

A sub-250g drone without a C0 class marking falls under the legacy or transitional provisions. Under these provisions, the drone can still fly in the A1 subcategory, but the pilot must not intentionally fly over uninvolved people. This is a meaningful operational restriction, particularly in urban environments.

Popular Sub-250g Models on the UK Market

DJI Mini 4 Pro

The DJI Mini 4 Pro has a listed MTOM of 249g with its standard Intelligent Flight Battery. DJI has obtained a C0 class marking for this model, which means it can operate in the A1 subcategory including flight over uninvolved people. It features a 4K camera capable of recording at 60 frames per second and a quoted flight time of around 34 minutes with the standard battery.

One important compliance consideration: the DJI Mini 4 Pro is also sold with an Intelligent Flight Battery Plus, which increases the total weight above 250g. If you use this larger battery, the drone no longer qualifies as a sub-250g aircraft and different rules apply. Always check the manufacturer specifications for your specific configuration.

DJI Mini 3

The DJI Mini 3 has a listed MTOM of 248g. A C0 class marking is available for this model. Like the Mini 4 Pro, it can operate in the A1 subcategory with the ability to fly over uninvolved people when carrying the C0 mark. It features a 4K HDR camera system. Note that the DJI Mini 3 and the DJI Mini 3 Pro are separate products with different specifications, though both are listed under 250g.

DJI Mini 2 SE

The DJI Mini 2 SE has a listed MTOM of 246g. However, this model may not carry a C0 class marking depending on the region and production batch. If your specific unit does not have a C0 mark, it flies under legacy transitional rules. This means you can operate in the A1 subcategory, but you must not intentionally fly over uninvolved people. It features a 2.7K camera and is positioned as an entry-level option in the DJI Mini range.

Holy Stone Sub-250g Models

Holy Stone manufactures several drone models with listed weights under 250g, including the HS175D and HS720E among others. These models generally do not carry a C0 class marking, which means they fly under legacy transitional rules with the restriction against intentional flight over uninvolved people. They typically do not include geofencing systems. The same CAA registration requirements apply: you need a Flyer ID, and if the drone has a camera, you also need an Operator ID.

Other Sub-250g Options

The sub-250g market continues to expand. Models from manufacturers such as Autel, Hubsan, Potensic, and others are available in the UK. The same compliance framework applies to all of them: check the MTOM on the manufacturer datasheet, determine whether the specific unit carries a C0 class marking, and operate accordingly. The weight listed on a product page may differ from the actual MTOM of your specific unit when accessories, propeller guards, or different batteries are fitted.

Registration and Identification Requirements

Regardless of which sub-250g drone you choose, the CAA registration requirements are consistent:

• Flyer ID: Required for anyone flying a drone. You must pass the CAA online theory test. The Flyer ID is free and valid for 5 years
• Operator ID: Required if your drone has a camera or weighs 250g or more. Costs 10.33 GBP per year. Your Operator ID must be displayed on the drone
• Minimum age: You must be at least 12 years old to obtain a Flyer ID. There is no minimum age for an Operator ID, but a person under 18 must have a parent or guardian register as the operator

These requirements apply equally to DJI, Holy Stone, Autel, and every other manufacturer. The rules are based on the aircraft characteristics, not the brand.

Flight Restrictions That Apply to All Sub-250g Drones

Even with a sub-250g drone, certain restrictions always apply in the UK:

• Maximum altitude of 120 metres (400 feet) above the surface
• Visual line of sight must be maintained at all times unless a specific authorisation has been obtained
• Flight Restriction Zones around airports, prisons, and other protected sites must be respected
• The Drone and Model Aircraft Code must be followed
• You must not fly in a way that endangers anyone or anything
• Night flying requires appropriate lighting on the drone

The sub-250g weight class relaxes some restrictions compared to heavier drones, but it does not create a free pass. Responsible operation and awareness of airspace restrictions remain essential.

Choosing a Model: Compliance Factors to Consider

When evaluating sub-250g drones for use in the UK, consider these compliance-related factors:

1. Verified MTOM: Check the manufacturer datasheet for the maximum take-off mass. Do not rely on marketing claims alone. Weights can change with firmware updates, accessories, and regional variants
2. C0 class marking: Determine whether your specific model and region has a C0 mark. This directly affects where you can fly
3. Battery variants: Some models offer multiple battery options. A larger battery may push the total weight above 250g, changing your regulatory category
4. Geofencing: Some manufacturers include geofencing software that prevents flight in restricted zones. This is a helpful safety feature but does not replace your legal obligation to check airspace restrictions
5. Camera capability: Any drone with a camera triggers the Operator ID requirement, regardless of weight
