GDPR Compliance for UK Drone Pilots: Obligations and Best Practices

The moment your drone's camera can identify a person, you are legally a 'data controller' with serious responsibilities – a fundamental principle for every GVC licensed drone pilot operating in the UK.

Whether you're a commercial drone operator ensuring your business is fully compliant or a recreational drone pilot trying to avoid legal pitfalls when sharing footage online, this guide provides the on-the-ground tactics we use to fly safely and legally.

Any Personal Data Captured By A Drone Is Subject To GDPR

Drones can capture personal data (e.g., identifiable images or videos of individuals) even when that is not the intention. Under the UK GDPR (and Data Protection Act 2018), any drone photo or recording in which people can be identified is considered personal data and triggers data protection obligations.

This means drone pilots who collect such footage become data controllers responsible for complying with GDPR requirements.

Key obligations include ensuring a lawful basis for processing, respecting privacy, and adhering to the core data protection principles (lawfulness, fairness, transparency, data minimisation, etc.).

• Drone pilots should avoid recording individuals who are not relevant to the purpose of the flight.

• Only collect data that is adequate, relevant and limited to what is necessary for your stated purpose. Because drones can hover at altitude and use zoom, there is a higher risk of “collateral intrusion” – inadvertently filming people in surrounding areas.

• Drone operators must be prepared to justify the necessity of using a drone instead of less intrusive methods. Before deploying a drone, especially for surveillance or monitoring, consider if the objective could be met through alternative means with less impact on privacy (for example, using on-site observers or fixed cameras in limited areas).

It is illegal and a GDPR breach to use a drone to film people in areas where they reasonably expect privacy. This applies to places such as inside their home or fenced garden without their permission.

In such cases, no lawful basis would justify the intrusion. Always avoid spying into private property – if a task requires inspecting private premises (e.g. a roof inspection), inform the property owners and neighbors in advance and confine footage strictly to the area of interest.

Under GDPR, you need a valid lawful basis (Article 6) to process personal data collected by a drone

While consent is one lawful basis, in practice it is difficult to obtain genuine consent from everyone captured by a drone in public spaces.

Therefore, most drone pilots rely on “legitimate interests” (for private companies) or “public task” (for public authorities) as the lawful basis for filming, provided they implement safeguards to protect individuals’ rights.

Consent is generally not required for incidental filming in public if you have another lawful basis and you are transparent. However, if a drone will deliberately focus on specific individuals or record in a sensitive context, you may need to seek consent or at least give those individuals an opportunity to opt out.

GDPR’s transparency principle means people should be informed when their data is being collected by a drone.

A key challenge is that individuals often won’t realize a drone is recording them or know who is controlling it. Drone pilots must proactively provide privacy information to individuals who might be recorded. In practice, you should use multiple methods to notify people:

Flyers or letters to residents

If you plan to fly a drone over a neighbourhood or other populated area, consider sending notices or flyers to nearby residents beforehand. Inform them when and where the flight will occur, the purpose of the drone operation, and who is operating it.

Include your contact details (or your organisation’s) so people can ask questions or raise concerns. Such notification helps ensure that people aren’t caught by surprise and understand why the drone is overhead.

Practical Example: University Halls of Residence Roof Inspection

On one project, we were hired to conduct a detailed roof inspection of several large halls of residence for a university. To ensure we were completely transparent, we created flyers and posted them through the doors of all the affected student flats. We also coordinated with the university administration, who put up official notices in the building lobbies about a week before the flight.

On the flyer, we made sure to clearly state:

• The exact date and a two-hour time window for the survey (12:00 PM - 2:00 PM).

• The purpose of the flight (a structural roof inspection).

• A brief explanation of how the data would be securely stored and used only for the inspection.

• Our company name and contact information in case anyone had questions.

This proactive communication made all the difference. On the day of the flight, we received no complaints or concerned calls because the residents knew who we were and exactly why the drone was there. It built trust and allowed us to complete our work efficiently and in full compliance with data protection principles.

Signage in the area

Posting temporary signs is an effective way to alert the public at the location of filming. For example, before launching the drone, place signs around the perimeter or entrances to the area stating that drone recording is in progress or will occur, the purpose (e.g., “drone roof inspection” or “survey filming”), and the drone operator’s identity.

The UK Information Commissioner’s Office (ICO) specifically suggests using signage to explain a drone’s use in the area. Be transparent about who is responsible for the drone and provide a way to get more information (such as a QR code or URL to a full privacy notice).

I highly recommend investing in a set of good-quality, reusable signs. They are fairly cheap to produce and will last for ages, making them a simple and effective tool for maintaining transparency on all your future projects.

Online privacy notice

Have a publicly accessible privacy notice (e.g. on a website or social media page) with detailed information about your drone data processing. The notice should cover the purpose of the filming, your lawful basis, how long data will be kept, who it may be shared with, and importantly individuals’ rights (like the right to request deletion of their images).

In your flyers and signs, direct people to this notice for full details. For instance, a sign might say “Drone filming in progress for survey purposes. Visit https://www.google.com/search?q=www.example.com/drone-privacy for more information."

Verbal announcements when feasible

In situations like events or controlled environments, make a verbal announcement about the drone. For example, at the start of an outdoor event, an announcement could inform attendees that a drone will be filming overhead, why it’s being used, and whom to contact with concerns.

While not always practical in wide public spaces, a verbal notice can supplement signs for added transparency.

I find it's most effective to have my visual observer or spotter be responsible for this. In addition to the main announcement, I also have them clearly and loudly announce when the drone is taking off and again just before it lands.

Be visible and approachable

The Civil Aviation Authority (CAA) advises making sure you can be clearly seen when flying. Wear a high-visibility vest with text for identification as the drone operator.

This way, if people notice the drone, they can also spot you on the ground and know who is responsible. Being approachable allows individuals to come ask what you are doing – a form of on-the-spot transparency.

When is consent needed?

Getting explicit consent from every bystander is usually impractical. Instead, focus on legitimate interests balanced with privacy rights.

That said, if your drone use is more intrusive than the average person would expect, seeking consent might be appropriate.

• Example 1 (Legitimate Interests): A wide, sweeping shot of a public square where people are walking by in the background is generally acceptable under "legitimate interests." The people are incidental to the shot, not the focus. You are being transparent by having spotters, wearing high-vis clothing, and perhaps placing signs in the area.

• Example 2 (Consent Needed): If you then fly the drone low to capture close-up, high-definition footage of a specific street performer's act and the cheering crowd around them, you are now deliberately focusing on identifiable individuals. In this case, you should approach the performer and their audience beforehand to explain what you're doing and get their permission. This gives them a clear opportunity to consent or "opt-out" by moving away.

• Example 3 (Hobbyist): If you're a hobbyist drone pilot flying over a friend's garden during a BBQ, you must get permission from your friend (the landowner) and also make sure every guest is aware and agrees to be filmed. You can't just assume everyone is okay with it.

Always err on the side of respect for privacy: if someone objects to being filmed by your drone and you do not have an overriding necessity, be prepared to stop or avoid capturing them. Public authorities using drones (like police or councils) should rely on their statutory functions (public task) but still notify the public wherever possible to maintain trust.

Drone Data Storage and Retention GDPR Policies

Once personal data is collected via drone (videos, photos, or audio), GDPR requires careful handling of that data. Drone operators must have clear data storage and retention policies:

Store recorded footage securely to prevent unauthorized access

Drones often use memory cards or transmit data to base stations – ensure these are protected. Use encryption or password protection on any devices or servers storing drone footage.

This is especially important because drones can be lost, stolen, or accessed if they crash; encryption helps protect the data if the device falls into the wrong hands. Limit access to the footage – only allow personnel with a need-to-know to view or copy it.

Only retain drone footage for the shortest time necessary to fulfill the purpose for which it was recorded.

There is no fixed rule, but you should define a reasonable retention period based on your needs. For example, a 60-day maximum retention unless an incident requires keeping footage longer.

Delete or anonymize data as soon as it is no longer required. The CAA explicitly advises: “Store images safely. Delete anything you don’t need.”

Ensure secure deletion of digital files

Simply deleting a file might not remove it completely. Consider overwriting or using reputable deletion tools for sensitive recordings.

If footage was stored on removable media (SD cards), ensure they are wiped or destroyed when no longer used. You can often reformat the SD card directly from the drone's settings menu.

Treat drone data like any personal data – do not share it or publish it unless necessary

Do not post or share videos of people in a harmful or unfair way. If you must share footage with a third party, ensure that third party is GDPR-compliant and the sharing is covered in your privacy notice.

GDPR Differences Between Commercial and Recreational Drone Pilots

The law makes a distinction between individuals flying drones for purely personal purposes and those using drones for any professional or commercial purpose.

If you are a hobbyist drone pilot flying a drone for truly personal, you fall under the “domestic purpose” exemption of data protection law.

If you fly a drone just for fun (e.g., videos of your own family, vacation scenery) and do not share the footage beyond your private sphere, the GDPR likely does not apply. However, the moment you step beyond purely personal use (e.g., uploading to a monetized YouTube channel, sharing footage of neighbors on social media), data protection rules kick in.

Any commercial drone operation is fully subject to GDPR.

Organizations or individuals using drones as part of a business, research project, or public service are considered data controllers. They must comply with all data protection principles, which may include registering with the ICO, conducting DPIAs for high-risk processing, and implementing full technical and organizational measures.

When in doubt, it’s safest for a recreational user to assume the principles of GDPR do apply, especially if recording in public.
