Is it a bird, is it a plane… or is it trespass?
Key points
- Drone use is increasing rapidly across the UK.
- Property owners do not own unlimited airspace above their land.
- Low-altitude drone flights may give rise to trespass, nuisance, privacy or data protection issues.
- Current case law remains highly fact specific.
- As commercial drone use expands, courts may face new questions about low-level airspace rights.
Drones, airspace and property rights in England and Wales
Imagine ordering a parcel in the morning and watching it descend into your garden an hour later, delivered by drone.
This is no longer science fiction. In May 2026, Amazon became the first retailer to make drone deliveries to customers in the UK, operating its Prime Air service from a centre in Darlington under a Civil Aviation Authority trial authorisation. For one resident in Darlington, that prospect became rather more literal in July 2026, when an Amazon Prime Air drone crashed into a garden mid delivery. No one was hurt but the UK Air Accident’s Investigation Branch opened an inquiry – a reminder that “delivered by drone” can occasionally mean more than the marketing suggests.
For those accustomed to thinking of drones as toys or tools of military surveillance, the pace of this change is striking. Drones are now used routinely for surveying, infrastructure inspection, media production, and security monitoring, as well as parcel deliveries. They operate at altitudes far lower than conventional aircraft, meaning they pass not over empty sky but over gardens, farms, construction sites, and private estates.
As their use grows, so do the questions they raise for landowners and occupiers: who controls the airspace above private land, what can a landowner do when a drone hovers uninvited, and does the law, much of it written long before the first consumer drone took flight, have adequate answers?
Although the regulatory framework is well established, the intersection of aviation regulation and private property rights remains an evolving area of law.
The regulatory framework
Drone operation in the UK is regulated by the Civil Aviation Authority, which publishes operational guidance through the Drone and Model Aircraft Code.
Under the Code, anyone flying a drone weighing 100g or more will generally require a Flyer ID. An Operator ID may also be required, including where a drone weighs 250g or more or weighs 100g or more and is equipped with a camera. Operators must generally fly below 120 metres, keep the drone within visual line of sight, and ensure that flights do not endanger people or property. Operators are also expected to respect privacy and obtain permission before retrieving a drone from private land.
The statutory framework underpinning these rules is contained primarily in the Air Navigation Order 2016, which classifies drones as unmanned aircraft and imposes restrictions on matters such as altitude limits, proximity to airports and flights near people or congested areas. Breaches may constitute criminal offences. Enforcement sits primarily with the police, who may investigate ANO breaches, and with the Civil Aviation Authority, which has powers to investigate and impose civil sanctions. Landowners or members of the public who believe a drone is being operated unlawfully can report the matter to either body, though in practice the police will often be the first port of call for incidents occurring in the course of a flight.
The Civil Aviation Act 1982 also plays an important role. Section 76 provides that no action for trespass or nuisance arises solely by reason of aircraft flying over land at a reasonable height, provided the flight complies with aviation regulations. At the same time, the Act also imposes strict liability where an aircraft causes damage or injury on the ground.
Where drones are equipped with cameras, data protection and privacy obligations arise in addition to the aviation framework which are considered below.
Trespass and airspace rights
While aviation regulation governs how drones may be flown, the question of whether drone activity infringes private property rights is determined by the law of trespass.
Trespass to land is a strict liability tort involving unauthorised intrusion onto land. Accordingly, a claimant is not required to establish loss or damage in order to bring a claim.
The courts have long recognised that trespass may extend into the airspace above land. In Kelsen v Imperial Tobacco Co Ltd [1957], an advertising sign projecting only a few inches into neighbouring airspace was held to constitute an actionable trespass.
Similarly, in Anchor Brewhouse (Docklands Developments) v Berkley House Ltd [1987], the use of tower cranes that swung through neighbouring airspace during construction works was restrained by injunction.
These authorities demonstrate that airspace rights are capable of protection. The more difficult question is how far those rights extend vertically.
The Bernstein principle
The leading authority is almost fifty years old. In Bernstein v Skyviews & General Ltd [1978], aerial photographs of the claimant’s property were taken from several hundred feet above ground.
The court rejected the notion that landownership extends indefinitely upwards, holding instead that a landowner’s rights extend only as far as necessary for the ordinary use and enjoyment of the land and its structures.
Flights at a sufficiently high altitude will therefore not infringe property rights. However, the decision provides limited guidance in the context of modern drone technology. It does not define the lower boundary of protected airspace or identify when low-level aerial activity becomes sufficiently intrusive to interfere with land use.
The difficulty is that Bernstein predates the widespread use of small, manoeuvrable drones capable of operating close to the ground, often for extended periods and with increasingly sophisticated cameras. It is also worth noting that where overflight does not constitute trespass, affected landowners may still have recourse to the law of private nuisance, the Protection from Harassment Act 1997, or the privacy and data protection frameworks considered below.
Recent drone litigation
The courts have only recently begun to consider disputes involving drone overflight, and the emerging case law indicates that the issue is likely to remain highly fact-specific.
In MBR Acres Ltd and others v Curtin [2025], drones were flown over a commercial animal breeding facility by animal welfare activists protesting against the use of animals in laboratory research. The claimants sought an injunction preventing flights below 100 metres and restraining “persons unknown”.
Applying the Bernstein principle, the court concluded that drone flights at approximately 50 metres did not materially interfere with the use of the land and therefore did not constitute trespass. This conclusion turned on the particular facts of the case, rather than establishing any general safe altitude. The claim against unidentified operators also failed due to insufficient evidence regarding the height and frequency of the flights. The court also observed that the law of trespass cannot be used simply to prevent aerial photography where flights occur within lawful airspace.
By contrast, in Anglo International Upholland Ltd v Wainwright [2023], drones were flown over a private estate and used to gather information that facilitated physical trespass onto the land. The court granted an injunction, indicating that the purpose and consequences of drone activity may be relevant when determining whether legal relief is appropriate. The contrast with MBR Acres is instructive: it was not the overflight itself that justified relief, but the use to which the information gathered was put.
Taken together, these decisions indicate that routine drone overflight is unlikely to amount to trespass unless it materially interferes with the use and enjoyment of land. However, the position may be more complex where drones are used in a targeted or persistent manner. Repeated low level flights intended to harass landowners or disrupt lawful activity, such as farming or construction, may give rise to claims under the law of private nuisance or the Protection from Harassment Act 1997, even where the technical threshold for trespass is not met.
Privacy and data protection
Trespass and nuisance are not the only legal frameworks engaged by drone activity. Where drones are equipped with cameras, a distinct but complementary body of law applies, and landowners and occupiers should be aware of the additional remedies and protections which may be available.
The Information Commission has published guidance on surveillance technologies that expressly includes drones, emphasising the need for operators to minimise the collection of personal data and adopt a “privacy by design” approach.
Under the UK GDPR and the Data Protection Act 2018, drone footage in which individuals can be identified constitutes personal data. Complaints about unlawful data collection may be made to the Information Commission, which has the power to investigate and impose enforcement action. However, data protection law is focused on the processing of personal data and will not always provide a practical remedy where the primary concern is intrusion over land.
Beyond data protection, the tort of misuse of private information may also be relevant. Established in Campbell v MGN Ltd [2004], the tort applies where a person has a reasonable expectation of privacy in respect of information obtained or disclosed without consent. While Campbell concerned publication rather than aerial surveillance, the underlying principles may extend to drone activity. In particular, courts recognise that location and context are key, and a home or private garden will ordinarily attract a reasonable expectation of privacy. Whether drone footage of such areas will found a claim is fact specific and is yet to be determined.
Where drone gathered images are then commercially exploited, for example through publication of private or commercially sensitive activity, claims in breach of confidence may also arise. This too remains an area which is yet to develop fully in the drone context.
Key takeaways for landowners
For landowners encountering drone activity above their property, the legal position may not always be straightforward. Several practical steps may assist in assessing whether legal action is appropriate.
- Assess compliance with aviation rules: Flights that breach aviation regulations may be reported to the police or the Civil Aviation Authority.
- Gather evidence: Drone disputes are highly fact specific. Landowners should record the approximate altitude, frequency and duration of flights, as well as any disruption caused to land use or tenant operations.
- Identify the operator: Registration requirements may assist in identifying drone operators, which is often necessary before legal remedies can be pursued. Where the drone falls below the registration threshold, or where the operator cannot be traced through registration records, landowners may wish to record any identifying markings on the drone, note the time and direction of travel, and consider whether CCTV or other footage is available. In some cases, the Civil Aviation Authority or police may be able to assist with operator identification.
- Consider the level of interference: Occasional or incidental overflight will rarely justify legal action. Courts typically require evidence of persistent or intrusive interference.
- Consider alternative claims: Where trespass cannot easily be established, nuisance, harassment or privacy related claims may provide alternative legal routes. These alternatives can be particularly relevant where drone activity is persistent, targeted, or connected to the commercial exploitation of footage or information gathered over private land. Where drone footage captures identifiable individuals in circumstances where they have a reasonable expectation of privacy, a complaint to the Information Commission may also be appropriate.
Future developments
The Amazon Prime Air launch in Darlington is not an isolated development. It signals a broader shift towards commercial drone use at scale.
Government and industry are already testing the infrastructure required to support this. For example, Project Skyway has trialled the concept of a dedicated drone corridor across parts of England, designed to enable drones to operate safely beyond the visual line of sight of their operators over long distances. At a regulatory level, the Civil Aviation Authority has also set out a roadmap intended to allow routine commercial delivery drone operations beyond visual line of sight by 2027, paving the way for more widespread commercial use, including delivery services.
If these developments are implemented at scale, this could lead to regular and predictable drone traffic over private land, rather than the occasional or incidental overflight considered in current case law.
This raises questions that existing law is not designed to answer directly. While the Civil Aviation Act 1982 protects overflight at a “reasonable height”, that framework developed with conventional aircraft in mind, not frequent, low level drone activity operating on commercial routes. If such activity becomes sufficiently regular or intrusive, landowners may seek to characterise it as nuisance rather than relying on trespass alone.
While current case law suggests that routine overflight will not amount to trespass (unless it materially interferes with the use of land or forms part of a broader unlawful activity), systematic and frequent drone activity may test the boundaries of nuisance and airspace rights.
Therefore, the Amazon parcel descending into a Darlington garden is, in legal terms, only the beginning. As drone deliveries move from novelty to normality, disputes about low level airspace are likely to become increasingly common. The question for the courts, and perhaps eventually Parliament, will be how to strike a balance between the rights of private landowners and the economic and social benefits of embracing new technologies.
Until then, landowners may find themselves looking upwards more often than they used to. What was once largely empty airspace is becoming increasingly busy, and the law is still working out exactly where the boundaries lie.
