Background: Why the Rules Diverged

Prior to 31 December 2020, UK drone operators followed EASA regulations alongside their EU counterparts. After the Brexit transition period ended, the UK Civil Aviation Authority (CAA) assumed full regulatory authority over unmanned aircraft in British airspace. The EU meanwhile continued developing its framework under EASA Regulation 2019/947 and Delegated Regulation 2019/945.

The result is two parallel systems that share common ancestry but have diverged in several practical areas. Operators who fly in both jurisdictions need to understand both frameworks. As of May 2026, mutual recognition of qualifications remains limited, meaning UK certifications are not automatically valid in EU airspace and vice versa.

Registration Requirements

In the UK, any drone weighing 250g or more, or any drone fitted with a camera regardless of weight, must be registered with the CAA. The operator registration costs GBP 10.33 per year. Each registered operator receives an Operator ID and a Flyer ID, both of which must be displayed on the drone or carried during flights.

In the EU, EASA requires registration for drones weighing 250g or above, or drones equipped with sensors that can capture personal data. Registration is handled by the national aviation authority in each member state, with fees varying by country. The EU system also issues a unique operator registration number.

A key difference is portability: an EU operator registration obtained in one member state is valid across all EU and EEA countries. UK registration, however, is valid only within UK airspace.

Drone Categories and Classifications

Both the UK and EU use a three-category system — Open, Specific, and Certified — but the details vary. The UK introduced its own class marks (C0 through C4 and transitional categories) mirroring the EU C-marks, though post-Brexit drones sold in the UK may carry UK-specific markings rather than EU CE marks.

The EU Open category is divided into subcategories A1, A2, and A3, each with rules about proximity to people and required competencies. The UK mirrors this structure but applies its own definitions. In the Specific category, both frameworks reference SORA (Specific Operations Risk Assessment), though the UK CAA and EASA have adopted different versions and timelines for SORA 2.5 implementation.

Altitude and Distance Limits

Both the UK and EU impose a maximum flight altitude of 120 metres (400 feet) above ground level in the Open category. This is one of the areas where the rules remain closely aligned.

Visual line of sight (VLOS) requirements also remain similar in both jurisdictions. Pilots must maintain unaided visual contact with the drone at all times in the Open category, unless a specific authorisation for beyond visual line of sight (BVLOS) operations has been granted under the Specific category.

Insurance Requirements

In the UK, third-party liability insurance is required for all commercial drone operations and strongly recommended for recreational flights. The minimum coverage depends on the drone's maximum take-off mass (MTOM) and the nature of the operation.

Under EU Regulation (EC) No 785/2004 as amended, insurance is mandatory for drones with an MTOM of 20 kg or more, or for any commercial operations. Several EU member states have additional national requirements that may lower this threshold. Operators should check the specific requirements of each country they intend to fly in.

Commercial Licensing

UK commercial drone operators must obtain either an A2 Certificate of Competency (A2 CofC) for operations near people or a General VLOS Certificate (GVC) for a wider range of commercial work under an Operational Authorisation. The GVC requires completing an approved training course and passing both a theoretical examination and a practical flight assessment.

In the EU, commercial operations in subcategory A2 require a remote pilot certificate of competency issued after passing an additional theoretical exam and a self-declared practical assessment. Operations in the Specific category require either a declaration using a standard scenario or an individual authorisation from the relevant national authority.

No-Fly Zones and Airspace Restrictions

The UK designates Flight Restriction Zones (FRZs) around airports and other sensitive sites. These are published by the CAA and enforced under the Air Navigation Order 2016. The UK also maintains Temporary Danger Areas and other notified restrictions.

EU member states designate UAS geographical zones under EASA rules, but the specific implementation varies by country. Some nations use electronic conspicuity requirements or mandatory geo-awareness databases. Operators must check the relevant national maps and NOTAM systems before each flight.

Key Differences at a Glance

Flying in Both Jurisdictions

If you hold a UK Flyer ID and plan to fly in an EU member state, you will generally need to register separately with the relevant national authority and may need to obtain additional qualifications recognised under EASA rules. Similarly, EU-registered operators visiting the UK should check the CAA website for any recognition arrangements or visitor permissions that may apply.
