How to Register a Drone in the UK

Who Needs to Register

If you fly a drone or model aircraft in the UK, registration with the Civil Aviation Authority is a legal requirement in most cases. The obligation applies to anyone who operates a drone weighing 250 grams or more, or any drone fitted with a camera, regardless of weight. This means even small camera-equipped drones that weigh under 250 grams must be registered.

The registration requirement applies equally to recreational flyers, hobbyists, and commercial operators. There is no exemption based on how frequently you fly or whether you intend to sell footage. If you are the person flying the drone, you need a Flyer ID. If you are responsible for the drone itself, whether as the owner or the organisation that manages it, you need an Operator ID.

Understanding the Two IDs

The CAA registration system issues two distinct identification numbers, and understanding the difference between them is important.

The Flyer ID is personal to the individual who physically controls the drone during flight. It confirms that the person has passed the required theory test and understands the basic rules of drone flight in UK airspace. Each person who flies a drone needs their own Flyer ID.

The Operator ID belongs to the person or organisation that is legally responsible for the drone. This is the ID that must be displayed on the aircraft itself. One Operator ID covers all drones under that person's or organisation's responsibility, no matter how many aircraft they own.

In many cases, the same individual holds both IDs. A recreational flyer who owns one drone will register once and receive both a Flyer ID and an Operator ID. However, in commercial settings or family situations, the person flying may be different from the person who owns the drone. A photography business, for example, would hold the Operator ID, while each pilot on staff would hold their own Flyer ID.

Step-by-Step Registration Process

The registration process is handled entirely online through the CAA's dedicated registration portal. Here is what to expect at each stage.

Step 1: Create Your Account

Navigate to register-drones.caa.co.uk and create a new account. You will need to provide your name, email address, and a password. If you are registering as an individual rather than an organisation, select the individual registration option. The CAA will send a verification email to confirm your address before you can proceed.

Step 2: Take the Flyer ID Theory Test

Once your account is active, you will be directed to the Flyer ID theory test. This is a multiple-choice examination consisting of 20 questions covering the fundamental rules of drone operation in the UK. Topics include airspace restrictions, privacy obligations, altitude limits, distance rules from people and buildings, and what to do in an emergency.

You need to answer at least 16 out of 20 questions correctly to pass. The test is not timed in a strict examination sense, so you can take it at a pace that suits you. If you do not pass on the first attempt, you can retake the test. The CAA provides study materials on their website to help you prepare.

Step 3: Receive Your Flyer ID and Operator ID

After passing the test and completing payment, the CAA will issue both your Flyer ID and your Operator ID. These are alphanumeric codes that you can view in your online account. The Flyer ID confirms your competence as a pilot. The Operator ID is what you must physically display on your drone.

Step 4: Label Your Drone

Attach your Operator ID to your drone so that it is visible and legible without the need for tools. Many operators use a small adhesive label or an engraving. The ID must be on the aircraft itself, not on the carrying case or the controller. If you own more than one drone, place the same Operator ID on each aircraft.

What the Theory Test Covers

The Flyer ID theory test draws from the core regulations governing drone use in the UK. While the exact questions vary, the test consistently covers the following areas:

• Maximum altitude of 120 metres (400 feet) above ground level in uncontrolled airspace
• Maintaining visual line of sight with your drone at all times during flight
• Distance restrictions from people not under your control, vessels, vehicles, and structures
• Flight restriction zones around aerodromes and other protected areas
• The requirement to give way to manned aircraft at all times
• Privacy obligations when flying a camera-equipped drone
• Emergency procedures and what constitutes reckless or negligent operation
• The penalties for flying without registration or in restricted airspace

The CAA updates the question bank periodically to reflect changes in legislation. As of 2026, the test reflects the current UK implementation of retained EU regulation and subsequent domestic amendments to the Air Navigation Order.

Common Mistakes to Avoid

Several issues regularly catch new registrants off guard. Being aware of them in advance will save time and potential frustration.

First, do not confuse the Flyer ID with the Operator ID when labelling your drone. It is the Operator ID, not the Flyer ID, that goes on the aircraft. Displaying the wrong number does not satisfy the legal requirement.

Second, remember that registration is annual. Your Flyer ID and Operator ID expire after 12 months. Flying with expired registration carries the same legal consequences as flying without registration at all. The CAA sends email reminders before your expiry date, but it is your responsibility to renew on time.

Third, if you buy a drone for someone else, particularly as a gift for a younger family member, be aware that children under 18 can obtain a Flyer ID but an adult must hold the Operator ID. The adult is legally responsible for the drone's operation.

After Registration: What Comes Next

Registration is the first step in legal drone operation, but it is not the only requirement. Depending on what you plan to do with your drone, additional obligations may apply. Commercial operators in the Specific category need an Operational Authorisation from the CAA. Flights near airports or in controlled airspace require separate permission. Flying at night or beyond visual line of sight involves additional training and approvals.

For most recreational flyers operating small drones in the Open category, the Flyer ID and Operator ID from the standard registration process are sufficient to fly legally, provided you follow the rules covered in the theory test.
