What counts as a lone worker
A lone worker is anyone who carries out their job without close or direct supervision, whether that is for part of a shift or the whole of it. The definition is broad. It covers fixed-site staff working out of hours, mobile employees such as engineers and care workers, home workers, and people in remote settings where help is not immediately at hand.
Lone working is not unlawful in the UK, and for many roles it is entirely routine. The point is not to eliminate it but to recognise that working alone can make some hazards more serious, because there may be no one nearby to notice a problem or raise the alarm quickly.
Identifying who works alone, and when, is the first practical step. Many organisations are surprised by how much lone working actually happens once they map early starts, late finishes, single-crewed visits and quiet periods on site.
UK law and HSE guidance
The Health and Safety at Work etc. Act 1974 places a general duty on employers to protect the health, safety and welfare of employees so far as is reasonably practicable. That duty applies fully to people who work alone, and it extends to protecting others affected by the work, such as members of the public or clients.
The Management of Health and Safety at Work Regulations 1999 require employers to assess the risks to lone workers and to put sensible control measures in place. The HSE does not treat lone working as a special legal category, but its published guidance sets clear expectations around assessment, supervision, training and the ability to summon help.
In short, the law expects a proportionate, documented approach. You are not required to make lone working risk-free, but you are required to understand the risks and take reasonable steps to manage them.
The employer duty of care
Duty of care means taking reasonable steps to prevent foreseeable harm. For lone workers, that includes making sure someone can raise the alarm and get help if something goes wrong, and that the organisation would actually notice if a worker failed to return or check in.
It also covers softer but real risks. Isolation can affect wellbeing, and lone workers can be more exposed to aggression from members of the public. A responsible approach considers physical safety, mental health and the practical question of how a distressed or injured worker would be located and reached.
Duty of care is ongoing rather than a one-off exercise. Roles change, sites change and staff change, so arrangements need reviewing whenever the work or the workforce shifts significantly.
Risk assessment and common risks by setting
A lone worker risk assessment follows the same logic as any other: identify the hazards, decide who might be harmed and how, evaluate the risks, record your findings and review them. The difference is that you must factor in the absence of immediate help and the difficulty of summoning it.
Risks vary by setting. Care and NHS community staff face aggression, medical emergencies and lone travel. Construction and forestry involve falls, machinery and remote sites with poor signal. Security and lone retail staff face confrontation and violence, while logistics and waste crews contend with roadside hazards and heavy plant.
For each role, ask three questions: what could go wrong, how would we know, and how quickly could we respond. Where the honest answers are troubling, that is where controls and technology should be focused first.
How lone worker technology reduces risk
Technology cannot remove hazards, but it can dramatically shorten the time between an incident and an effective response. A one-touch SOS lets a worker summon help discreetly, while man-down detection can raise an alarm automatically if someone falls or stops moving after a collapse.
Check-in and clock-on features confirm that a worker started and finished safely, and can escalate automatically if an expected check-in is missed. GPS location means responders know where to go, which matters most on remote or unfamiliar sites where a worker may be unable to describe their position.
Alarms are only as good as the response behind them. Connecting devices or apps to a monitored alarm receiving centre, or to a well-drilled internal escalation and buddy-dispatch process, ensures every alert reaches someone who can act. Platforms such as Vygard bring these elements together in one system.
Building a lone worker policy
A good policy translates your risk assessment into everyday practice. It should state who is covered, the procedures for checking in and raising the alarm, the equipment provided, and exactly what happens when an alarm is triggered or a check-in is missed, including who is responsible at each step.
Training and communication matter as much as the document itself. Workers need to know how to use their devices or app, feel confident that reporting concerns is welcomed, and trust that an alarm will bring a real response. Managers need to know their part in escalation.
Finally, treat the policy as a living tool. Review it regularly, learn from near misses and actual incidents, and check that the controls still match how the work is really done. A policy that sits unread in a drawer offers little protection.
Frequently asked questions
- Is it legal to work alone in the UK?
- Yes. Working alone is legal for most roles. Employers must still protect lone workers so far as is reasonably practicable under the Health and Safety at Work Act, which means assessing the risks, providing suitable controls and making sure help can be summoned and delivered if something goes wrong.
- What law covers lone worker safety in the UK?
- The main framework is the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999. Together they require employers to protect lone workers, assess the risks they face and put reasonable control measures in place, supported by HSE guidance on lone working.
- Does an employer have a duty of care to lone workers?
- Yes. Employers must take reasonable steps to prevent foreseeable harm to people who work alone. In practice that means assessing risks, ensuring workers can raise the alarm and get help, checking that a missed return would be noticed, and considering wellbeing as well as physical safety.
- What should a lone worker risk assessment cover?
- It should identify the hazards of the role, who could be harmed and how, and the specific risks of working without immediate help. It should record the controls in place, such as check-ins, SOS or man-down technology and escalation procedures, and set a date to review the assessment as work changes.
- How does lone worker technology help meet duty of care?
- It shortens the time between an incident and an effective response. SOS alerts, man-down detection, check-in monitoring and GPS location help you know quickly when something is wrong and where the worker is, and connecting alerts to a monitoring centre or escalation process ensures each one reaches someone who can act.
