How to Register an FPV Drone in the UK

Does Your FPV Drone Need Registration?

Whether you fly Tiny Whoops indoors or 5-inch freestyle quads at a field, UK registration rules apply to every FPV pilot. The CAA treats FPV drones exactly the same as any other unmanned aircraft — what matters is the weight and how you use it.

Here is the breakdown by weight class:

• Under 250g (Tiny Whoops, sub-250g micro builds): You need a Flyer ID only. No Operator ID is required for personal, recreational flying.
• 250g and over (most 5-inch freestyle, 7-inch long-range, and cinema rigs): You need both a Flyer ID and an Operator ID.

Most custom-built FPV quads sit well above 250g once you add a battery, camera, and video transmitter. A typical 5-inch freestyle build weighs between 500g and 700g. A 7-inch long-range platform can reach 800g to 1,200g. Unless you are flying a purpose-built micro quad, assume you need both IDs.

Flyer ID — The Theory Test Every FPV Pilot Takes

The Flyer ID confirms you understand basic UK airspace rules, privacy obligations, and safety principles. Every FPV pilot needs one, regardless of drone weight.

• Cost: Free
• Format: 20 multiple-choice questions, online
• Pass mark: 16 out of 20
• Validity: Renewed annually when you re-take the test
• Minimum age: No minimum age to hold a Flyer ID, though under-18s should be supervised

The test covers airspace boundaries, altitude limits (120m / 400ft maximum), rules around people and property, and emergency procedures. FPV-specific questions are not separated out — the test applies to all drone types equally.

Operator ID — Required for 250g+ FPV Builds

If your FPV drone weighs 250g or more at take-off (including battery), you must hold an Operator ID. This is the registration number you label your aircraft with.

• Cost: £10.33 per year
• What you get: A unique Operator ID beginning with "OP-" followed by a string of characters
• Labelling: Your Operator ID must be displayed on every drone you operate that weighs 250g or more. Many FPV pilots use a small sticker inside the battery bay or on the frame arm
• Minimum age: 18 years old to hold an Operator ID. Under-18 FPV pilots can fly under an adult's Operator ID

One Operator ID covers every drone you own. If you have three different FPV quads, you place the same Operator ID on all three.

Step-by-Step Registration Process

1. Go to register-drones.caa.co.uk
2. Create an account with your email address
3. Choose whether you need a Flyer ID only or both Flyer ID and Operator ID
4. Complete the 20-question Flyer ID test (you can retake it immediately if you do not pass)
5. If registering as an operator, pay the £10.33 annual fee
6. Receive your IDs by email — print or save them
7. Label your FPV drone with your Operator ID before your next flight

The entire process takes roughly 20 to 30 minutes, including the theory test. Your Flyer ID and Operator ID are valid from the date of issue and must be renewed each year.

FPV Drones Without Class Markings

Most FPV drones are custom-built or assembled from aftermarket components. Unlike mass-produced consumer drones from major manufacturers, these builds almost never carry a CE class marking (C0, C1, C2, etc.).

A drone without a class marking is treated as follows under UK rules:

• Under 250g, no class marking: Fly in the A1 Open subcategory. Keep a reasonable distance from uninvolved people. No Operator ID needed for recreational use.
• 250g to 25kg, no class marking: Fly in the A3 Open subcategory. You must stay at least 150 metres from residential, commercial, industrial, and recreational areas. This is the most common scenario for FPV pilots flying freestyle or long-range quads.

The A3 distance restriction is the single biggest operational impact for FPV pilots. It means you cannot legally fly a 500g freestyle quad in a public park or near houses unless you hold additional authorisations.

What Happens If You Fly Unregistered

Flying without the required Flyer ID or Operator ID is an offence under UK aviation law. The CAA can issue fixed penalty notices, and more serious violations can result in prosecution. Fines can reach up to £1,000 for registration offences.

Beyond the legal risk, flying unregistered means you are not covered by any insurance policy that requires valid registration — which is most of them.

Registration takes less than 30 minutes and costs at most £10.33 per year. There is no good reason to skip it.
