In short: Farm accidents in the UK killed 22 workers in agriculture, forestry and fishing in 2025/26, and many of those people were working alone. Where the holding has no mobile signal, nobody knows something has gone wrong until someone notices the absence, so coverage across the whole farm is a safety control as well as a business one.
Key Takeaways
- Farming is still the most dangerous job per head — HSE puts the five-year fatal injury rate in agriculture, forestry and fishing at around 21 times the all-industry rate, with 22 worker deaths in 2025/26.
- No signal turns an injury into a long wait — A farmer pinned under a quad bike or crushed in a cattle pen cannot call for help, and a lone-worker app cannot raise an alarm, if no network reaches that corner of the holding.
- A farm-wide network carries the alarm — One private 5G radio on a grain store roof can cover the yard and surrounding fields, so fall detectors, check-in timers and vehicle sensors reach the farmhouse and family phones wherever someone is working.
In a nutshell
How many farm accidents happen in the UK each year?
HSE's provisional figures for 2025/26 record 126 workers killed in work-related accidents across Great Britain, of whom 22 worked in agriculture, forestry and fishing. Only construction, with 25, killed more people, and construction employs many times more workers. Measured as a rate, HSE puts farming's fatal injury rate at around 21 times the all-industry average over the last five years. The Farm Safety Foundation puts the same picture another way: an industry employing about 1% of the working population accounts for roughly 18% of worker deaths.
The causes repeat year after year in HSE's accident-kind tables, with people struck by moving vehicles, trapped by something collapsing or overturning, caught in moving machinery, falling from height, and injured by livestock. Quad bike and tractor overturns, bale stacks shifting, and a cow with a newborn calf in a pen all appear in the case files. Across all industries, 40 of the 126 workers killed last year were aged 60 or over, and farming has one of the oldest workforces in the country.
Deaths are the visible end of the figures. For every fatality there are far more serious injuries, many of them on family farms where the injured person is self-employed and the incident never reaches RIDDOR at all.
Why does having no signal make farm accidents worse?
Because so much farm work happens alone, the time between an accident and the alarm is often set by when someone notices you are missing. A contractor in a busy yard is found in minutes. A farmer checking ewes on the hill at six in the morning, or fencing a boundary two kilometres from the house, can lie injured for hours before anyone thinks to go looking. In practice the first alarm is often a spouse wondering why lunch went cold.
A working phone shortens that delay, but only where there is signal. Many UK holdings still have patchy or no outdoor coverage once you leave the yard, particularly in valleys, behind tree lines and on upland ground. The Shared Rural Network programme set a target of 4G from at least one operator across 95% of the UK landmass, and a large share of the remaining area is exactly the hill and valley farmland where lone working is routine. Inside buildings the picture is worse: steel-clad grain stores, portal-frame cattle sheds and stone barns absorb what little signal reaches the yard.
The injury also changes what the person can do. Someone trapped under a quad bike may not be able to reach a phone in a jacket pocket, let alone unlock it and dial. That is why lone-worker devices with automatic fall and no-movement detection exist, and those devices need a network to send their alert.
Does 999 work on a farm with no signal?
A mobile phone will place a 999 call over any operator's network it can find, even if your own network has no coverage, so a farm with one bar of a rival network at the top of the drive can still make emergency calls from that spot. If no operator's signal reaches the place where the accident happens, the call cannot be made at all.
Satellite emergency messaging fills part of the gap. Recent iPhones and some Android handsets can send emergency texts via satellite in the UK, and dedicated satellite messengers do the same with an SOS button. They need a clear view of the sky and some time to connect, which works on an open hillside and fails under a tractor, inside a shed or in a steep wooded valley. They also rely on the injured person being conscious and able to operate the device.
The practical conclusion for most farms is that 999 coverage and lone-worker alerting are two separate problems. The first depends on public mobile networks reaching the holding. The second depends on any network at all that can carry an alert from a wearable or vehicle to someone who will respond, and that second network is one the farm can build for itself.
What does HSE expect from farms on lone working?
The Management of Health and Safety at Work Regulations 1999 require employers to assess risks to their workers, and HSE's lone-working guidance is explicit that the assessment should cover how a lone worker can raise the alarm and how someone will know if they have not. Its suggested controls include scheduled check-ins, a system to confirm a worker has returned at the end of a task, and automatic warning devices that trigger if a signal is not received.
Every one of those controls assumes communication. A check-in schedule fails silently if the worker's phone has no signal at the check-in time, and a man-down alarm that cannot transmit is a piece of plastic. HSE does not prescribe a technology, but an assessment that relies on a mobile phone across a holding where half the fields have no coverage would be hard to defend after an incident.
Self-employed farmers working alone on their own land sit largely outside the employer duties, but the risk to them is the same and arguably higher, because nobody else's routine depends on them turning up. Farms that take on seasonal workers, students or relief milkers do have the duty, and those are often the people least familiar with where the hazards are.
What changes when the whole farm has a network?
A private 5G network puts the farm's own coverage over the yard, the buildings and the surrounding fields, so devices can talk to each other and to the farmhouse wherever people work. Ofcom's Shared Access licences make suitable spectrum available to a farm or its network provider, and a radio unit mounted on the highest building, or on a short mast, typically covers one to two kilometres of open ground, less where terrain and woodland get in the way. A second or third radio extends that to an outlying block of fields.
For lone working, that network carries several kinds of alert:
- Wearable lone-worker devices with fall detection, no-movement timers and an SOS button, sending their alert and GPS position to the farmhouse, family phones or a commercial alarm receiving centre.
- Vehicle sensors on quad bikes, UTVs and tractors that detect a rollover or a sudden impact and raise an alarm without the driver doing anything.
- Check-in timers that escalate automatically if the worker does not confirm they are safe by a set time, rather than relying on someone at home remembering.
- Cameras in calving pens and bull pens that let someone back at the house see what is happening before they walk in.
The same network then serves the other work the farm already wants connectivity for, such as parlour data, grain store temperature probes, gate sensors and yard CCTV, which is how the cost stacks up. Safety is rarely the only reason a farm builds a network, but it is a reason that should shape where the coverage goes, because the dangerous corners of a holding are not always the busy ones.
What are the limits and costs?
A private network covers the holding and nothing beyond it. A worker who drives to a block of rented land five miles away leaves the coverage, and the lone-worker system needs to fall back to public mobile or satellite there.
A private 5G network also carries the farm's own traffic, not public calls. Phones on the farm will still look for a public operator's network to make a 999 call. If the farm wants public coverage as well, a neutral host arrangement can carry one or more mobile operators over the same radios, though that involves operator agreements and takes longer. For most farms, the realistic plan is a private network for alerts and data, plus the best available public coverage for voice, with satellite messaging as a backstop for workers on remote ground.
The devices bring their own discipline. A wearable with a flat battery protects nobody, so charging has to become part of the routine, in the same way as fuelling the quad bike. Fall detection also produces false alarms when a worker jumps down from a trailer or kneels to tag a lamb, and a system that cries wolf twice a week gets switched off. Setting sensible thresholds, and agreeing who responds and how quickly, matters as much as the coverage map. A sensible arrangement is a short written plan on the farmhouse wall: who gets the alert first, who is second if the first does not acknowledge within five minutes, and when to call 999 without waiting.
Cost depends heavily on terrain. A compact holding where one radio on a grain store sees most of the land is a modest project; a hill farm spread across three valleys may need several radio sites with power and backhaul at each. We survey the holding before quoting, because a coverage prediction built from 1 metre LiDAR terrain data shows which fields one radio will reach and which will need another, and the answer is often different from what the farmer expects.
Where should a farm start?
Start with the lone-working risk assessment rather than the technology. List who works alone, where they go, what they do there and how long it would take anyone to notice they had not come back. Then walk those locations with a phone that reports signal strength in dBm, and mark where it falls below roughly -110 dBm on every network. The overlap between the routine lone tasks and the dead zones is where the risk sits.
If that overlap is the hill fields, the calving shed and the far grain store, a private network sized to cover those places is the control the assessment is pointing at. If the farm already has good public coverage everywhere people work alone, a lone-worker app on existing phones may be enough, and we would say so.
Aerix designs and builds private 5G networks for UK farms, from single-yard installations to multi-site holdings. If your lone-working assessment has turned up places where nobody could call for help, send us the farm's postcode and a rough sketch of the fields people work in alone, and we will run a coverage prediction for the holding.
