Drones under 250 grams: what the law actually says

A drone under 250 g escapes many obligations — but not all of them. Subcategory A1, operator registration, training, remote identification: what the EU regulation says, and what changes from country to country.

Updated on .

A drone weighing less than 250 grams escapes many obligations — but certainly not all of them. Between the myths in circulation ("no licence needed", "no rules at all") and what the European regulation actually says, the difference matters. Here is what the law really says: first the baseline shared across the whole European Union, then what changes from one country to the next.

"Under 250 g": a key threshold, not a free pass

The 250-gram threshold is the best-known figure in drone regulation, and for good reason: it determines a large part of your obligations in the open category (the recreational regime set by Implementing Regulation (EU) 2019/947, which applies across the Union). Staying below that line lightens the framework considerably.

But beware the most widespread shortcut: "under 250 g" does not mean "no obligations". That is the single most common mistake. A light drone is still an aircraft, subject to safety rules, privacy rules and — very often — to an administrative formality most users overlook: operator registration.

A1: the subcategory for your lightweight drone

In the open category, a drone under 250 g falls into subcategory A1. This is the most permissive subcategory: it tolerates occasional, unintentional overflight of isolated people — which does not mean you may aim for them, and flying over assemblies of people remains prohibited at all times.

As with any flight in the open category, a few ground rules are non-negotiable:

C0 or no class marking: two families, one playing field

Not all drones under 250 g look alike on paper. There are two families, and both fly in A1.

The C0 class-marked drone

Since European harmonisation, new drones carry a class marking (C0 to C6). A compliant drone under 250 g receives the C0 marking. That covers most recent consumer aircraft in this weight range.

The drone without a class marking

Many drones sold before the class marking fully came into force carry no class at all. Such an aircraft weighing less than 250 g may fly under the conditions of subcategory A1 (above 250 g it falls into A3).

Watch out, though, for a condition that is rarely mentioned: flying in the open category requires a drone that bears a C0 to C4 class marking, or that was privately built (built for your own use), or that was placed on the market before 1 January 2024. An unmarked drone sold after that date meets none of these three conditions.

One practical point: an unmarked drone has no manufacturer-declared maximum take-off mass. Weigh your aircraft (battery and accessories fitted) to know which side of 250 g you are on.

The bottom line: C0 or eligible unmarked, under 250 g, you fly in A1.

What you are genuinely exempt from under 250 g

This is where the 250 g threshold really pays off. With a C0 or an eligible unmarked aircraft under 250 g:

Operator registration: the obligation everyone forgets

This is the most misunderstood point. People often assume a light drone means no paperwork at all. Wrong.

Across the Union, registration applies to the operator (you), not to the aircraft. It is mandatory as soon as the drone carries a camera or a sensor capable of capturing personal data, whatever its weight — so including under 250 g. Since virtually every recreational drone in this weight range is… a camera drone, virtually all of them must be registered.

The only real exception is the toy in the strict sense: an aircraft designed and marked as a toy, with no camera or sensor.

Two practical points:

The authority and the platform differ by country: see the table below.

The rules that still apply

Lighter does not mean exempt. Even with a tiny drone:

What changes from country to country

The framework set out above is European. The points below, by contrast, are decided by each Member State: these are the divergences that most often catch out remote pilots travelling abroad.

France Germany Spain
Night flying Prohibited in the open category, even with lighting fitted (a prefectural derogation is possible, to be requested at least 30 days in advance) Allowed, with the drone fitted with a flashing green light Allowed, with the drone fitted with at least one flashing green light
Operator registration With the civil aviation authority — free With the federal aviation office — chargeable (€20 for a private individual) With the national air safety agency — free, renewable every 3 years
Third-party liability insurance Not mandatory for recreational use (check the terms of your policy) Mandatory for every drone, with no weight threshold; proof must be carried Not mandatory in A1 or in A3 under 20 kg; mandatory in A2 and from 20 kg up
Minimum remote pilot age 14 16 (the European threshold was not lowered) 12 in A1 with a C0; 14 in the other open-category cases
National electronic signalling Yes, above 800 g, on top of class-based identification No: only class-based remote identification applies No: same
A1/A3 training Training and exam free Training material free, certificate chargeable (€25) Training and exam free
Flying over homes General open-category rules Prohibited without the owner's consent, unless the drone weighs 250 g or less with no recording capability, or you fly at at least 100 m height Prior notification to the authorities (at least 5 days) to fly in an urban environment, and no overflight of buildings and homes

One thing does not change: your operator registration and your training certificates are valid throughout the Union. It is the operating rules that differ from country to country, not your credentials.

FAQ

Does a drone under 250 g have to be registered?

Yes, in the vast majority of cases. As soon as the drone carries a camera or sensor, operator registration is mandatory, even under 250 g. Only a genuine toy without a camera is exempt. Which authority you register with depends on your country of residence.

Do I need training or a "licence" to fly a drone under 250 g?

No. In subcategory A1 with a C0 drone or an aircraft without a class marking under 250 g, no training or exam is mandatory. The free online training remains strongly recommended.

Does my drone under 250 g need remote identification?

No. Direct remote identification is not required for class C0. Some countries do add their own electronic signalling obligations above a mass threshold: see the table of national specifics.

What is the difference between a C0 drone and one without a class marking?

The C0 carries the European class marking. An unmarked aircraft does not: it may fly in A1 under 250 g, but only if it was privately built or placed on the market before 1 January 2024.

Can I fly at night with a drone under 250 g?

That depends on the country. The European regulation does not prohibit it as such, but some Member States forbid it in the open category while others allow it subject to lighting requirements. Check the rule of the country you are flying in.

Can I take my drone to another EU country?

Yes: the framework is European, and your operator registration and training are valid throughout the Union. But the national specifics (night flying, insurance, minimum age, zones) are those of the country where you fly.
