Open Category

Low-risk flying for most hobbyists and straightforward commercial missions. Learn the core Open Category rules and what the A1, A2 and A3 subcategories allow.

Open Category overview

For most recreational flyers, hobbyists, and many straightforward commercial users. The Open Category is designed for low-risk flights where safety requirements are easy to follow. Stick to the basics in the Drone Code and you can fly without a CAA Operational Authorisation.

Low risk

Key requirements

  • No CAA Operational Authorisation is needed.
  • A Flyer ID is required once the aircraft weighs 100 g or more.
  • An Operator ID is required for any drone with a camera from 100 g upwards and for all drones at 250 g or above. If 100-250 g with no camera, an Operator ID is optional.
  • Always keep your drone below 120 m (≈400 ft) AGL and within Visual Line of Sight (VLOS).
  • UK1, UK2, UK3, UK5 and UK6 class aircraft must broadcast Remote ID from 1 January 2026; UK0, legacy and privately built aircraft weighing 100 g or more with a camera, and model aircraft unless exempted, from 1 January 2028.

Where and how you can operate

  • Fly in most areas, including residential, commercial, and rural spaces depending on subcategory (see below).
  • No permission needed for most flights, except in restricted airspace such as aerodrome FRZs. Always check current restrictions and NOTAMs.
  • Recreational and commercial work allowed without CAA authorisation as long as you stay within Drone Code limits.

Standard restrictions

  • Never fly over crowds or assemblies of people.
  • Keep appropriate separation from uninvolved people. Class-marked aircraft have different allowances depending on subcategory.
  • Maintain VLOS at all times, unless flying FPV with a competent observer.
  • Never fly higher than 120 m (400 ft) AGL.
  • Never fly in restricted airspace without specific permission.
  • Do not fly if unfit or impaired by alcohol or drugs.

Qualifications and authorisations

Open Category subcategories

  • Drone class: UK0 (under 250 g) or UK1 (up to 900 g). EU C0 and C1 class drones are recognised and can fly in the A1 until 31 December 2027.
  • Qualification requirements: Flyer ID once the aircraft weighs 100 g or more; Operator ID for any camera-equipped aircraft and for all drones ≥250 g.
  • Where you can fly: Over uninvolved people (never over crowds or assemblies of people) across residential, commercial, industrial and rural areas when you comply with the Drone Code.

Key rules

  • Never fly over assemblies or groups of people and keep flights brief when over uninvolved people.
  • Switch on Remote ID from the applicable dates noted above.
  • Respect privacy and follow the Drone and Model Aircraft Code at all times.

Example Open Category operations

  • Flying a small camera drone in your local park.
  • Aerial photography of countryside or non-crowded spaces.
  • Real estate photography in an open area.
Note: The Open Category is intended for simple, low-risk flights. For more complex or higher-risk activities, step up to the Specific or Certified Categories.
