If you're planning to fly a drone in the UK in 2026, understanding the Civil Aviation Authority (CAA) regulations isn't optional—it's the law. Whether you've just bought your first FPV kit or you're upgrading to a larger rig, here's what you need to know to stay legal and avoid hefty fines.
The Big Change: 100g Registration Threshold
From 1 January 2026, the registration threshold drops from 250g to 100g. Any drone weighing 100g or more must be registered with the CAA. If your drone has a camera and weighs 100g or more, you'll need an Operator ID. Tiny whoops under 100g are generally exempt, even with cameras.
Operator ID vs Flyer ID: Know the Difference
The UK system uses two separate identifiers:
- Operator ID – This is tied to the drone owner. You pay approximately £10.50 per year, display this ID on every aircraft you own, and you only need one regardless of how many drones you have.
- Flyer ID – This is for the person actually flying. You obtain it by passing the free online theory test on the CAA website. If you're the only person flying your drones, you need both IDs.
Drone Categories Explained
UK drone regulations use a risk-based category system. The rules depend on where and how you fly, not whether it's for commercial purposes:
Open Category A1 (Very Low Risk)
Fly drones under 250g in built-up areas, but not over uninvolved people. From 2026, "legacy" drones (built before 2024) under 250g may continue operating here. Most sub-250g FPV whoops and toothpicks fall into this category.
Open Category A2 (Low Risk)
Fly drones up to 4kg in less congested areas, but you need an A2 Certificate of Competency (A2 CofC). This requires completing a training course and passing a theory exam through a CAA-recognised training provider. Legacy drones under 2kg can operate in A2 when flown by an A2 CofC holder, but must maintain 50m separation from uninvolved people. Newer Class-marked drones (C2) enjoy reduced distances of 30m, or just 5m in low-speed mode.
Open Category A3 (Higher Risk)
For larger drones up to 25kg in areas where no uninvolved people are present. A3 operations require passing the same theory test as A2 but with additional operational restrictions.
Where Can You Legally Fly?
The UK has restricted zones you must avoid:
- Flight Restriction Zones (FRZs) around airports and airfields—these extend several kilometres and are strictly enforced
- National parks and nature reserves often have local bylaws prohibiting drone use
- Residential areas require Category A1 or lower, with minimum distances from people and property
Use the Drone Safe website or apps like Drone Assist to check restricted airspace before every flight.
FPV-Specific Requirements
First Person View flying has additional rules:
- You must have a competent observer (spotter) who maintains visual line of sight with the drone at all times
- The spotter must be standing next to you and able to take control if needed
- Night flying is permitted but requires a flashing green light visible from all directions—this became mandatory from 1 January 2026
Commercial vs Recreational Flying
Since the UK moved to a risk-based system, the category you fly in depends on your drone's weight and where you fly—not the purpose. A commercial pilot can fly a sub-250g drone in A1 without additional certification, whilst a recreational pilot needs an A2 CofC to fly a 2kg drone in A2.
The key difference in 2026 is insurance: Commercial operators must have EC 785/2004 compliant insurance, whilst it remains optional (though recommended) for recreational flyers.
Remote ID Requirements
From 1 January 2026, all new drones sold in the UK must have Remote ID enabled, broadcasting their identity during flight. Legacy drones have until 1 January 2028 to comply. If you're buying new kit in 2026, ensure it's Remote ID ready.
Getting Started
Here's your checklist for legal UK drone flying in 2026:
- Register for an Operator ID at register-drones.caa.co.uk
- Complete the free Flyer ID theory test
- If your drone is 250g-4kg, consider an A2 CofC course for more flying flexibility
- Always check for FRZs before flying
- For night flying, attach a flashing green strobe light
- Fly safely, maintain visual line of sight, and respect privacy
For the most up-to-date information, always refer to the official CAA drones page. Regulations can change, and staying informed is your responsibility as a pilot.
