Alone on the Job — But Are They Safe?
What Every UK Employer Needs to Know About Lone Working
Because "They'll Be Fine" Is Not a Safety Procedure.
Every day, millions of people across the UK go to work alone. The community support worker visiting vulnerable residents on a housing estate. The engineer called out at midnight to fix a gas leak. The retail assistant who opens the shop at 7am before anyone else arrives. The delivery driver spending twelve hours on the road without seeing a colleague.
They are all lone workers and the chances are, some of your team are too.
Lone working is one of the most common, and most overlooked, areas of workplace health and safety. It doesn't always look dramatic. It doesn't always feel high-risk. But when something goes wrong, the consequences can be severe because there is no one there to help.
So, What Does "Lone Working" Actually Mean?
A lone worker is anyone who works by themselves without close or direct supervision for a period of time. This doesn't just mean someone who works in an isolated location it also includes people who:
Work from home
Travel between sites or visit clients alone
Work outside of normal hours when colleagues aren't present
Are the only person on-site, even in a busy public-facing setting
Work in remote or rural areas with limited communication
Lone working is not defined by isolation. It's defined by the absence of immediate support.
A Scenario: Meet Sarah
Sarah is a support worker for a care provider in the Midlands. She visits five clients a day, alone, often going into private homes where she has little control over the environment. Her employer considers her role low-risk she isn't working at height, she isn't using heavy machinery.
But last November, Sarah arrived at a client's home to find the situation had escalated. The client was in distress and became verbally aggressive. Sarah was alone, her mobile had poor signal, and she had no way to quickly alert her manager or a colleague. She managed to leave safely, but she was shaken for weeks afterwards.
"I didn't feel like I mattered until something nearly went wrong." Sarah, Support Worker
Sarah's situation is not unusual. And it is entirely preventable.
What Does the Law Say?
There is no single piece of legislation dedicated solely to lone working but that does not mean employers are off the hook. Quite the opposite.
Under the Health and Safety at Work etc. Act 1974, employers have a legal duty to ensure, so far as is reasonably practicable, the health, safety and welfare of all their employees. This duty does not diminish because someone is working alone.
The Management of Health and Safety at Work Regulations 1999 go further, requiring employers to carry out suitable and sufficient risk assessments for all workers including those who work alone. If an employer has five or more employees, those assessments must be recorded.
The Health and Safety Executive (HSE) is clear in its guidance: employers must consider whether the work can be done safely by one person, whether any specific risks increase when someone is alone, and what steps are in place to monitor and protect lone workers.
Key legal obligations include:
Risk assessment: Identifying the specific hazards lone workers face, including physical risks, violence and aggression, medical emergencies, and environmental factors.
Supervision and monitoring: Establishing systems to check on lone workers at regular intervals, especially for high-risk roles or locations.
Emergency procedures: Ensuring lone workers know what to do if something goes wrong, and that someone is able to raise the alarm on their behalf.
Fitness to work alone: Some workers may not be suitable for lone working due to medical conditions or experience levels, and this must be assessed.
Consultation: Employers are required to consult with employees or their representatives on health and safety matters, including lone working arrangements.
Failure to meet these obligations can result in enforcement action from the HSE, significant fines, civil liability claims and most importantly serious harm to your people.
Why Training Is Not Optional
Knowing the risks on paper is very different from being prepared to manage them in the moment. That's why training is a critical part of any lone working strategy.
Effective lone worker training should cover:
Understanding the risks : Lone workers need to be able to identify hazards specific to their role and environment, and understand why certain situations carry greater risk when working alone.
Communication protocols: Workers should know exactly how and when to check in, who their point of contact is, and what happens if they miss a scheduled call or message.
Conflict avoidance and de-escalation: Particularly relevant for those who deal with the public or work in care settings, training in managing difficult situations can make the difference between a near miss and a serious incident.
Emergency response: What to do in a medical emergency, how to summon help, and what information to provide. First aid training is strongly recommended for lone workers.
Use of lone worker tools and devices: Even the best technology is only effective if the person knows how to use it correctly and confidently.
Training should not be a one-off tick-box exercise. It should be refreshed regularly, adapted as roles change, and documented as part of your overall health and safety management.
Tools and Equipment That Make a Difference
Technology has transformed the way businesses can protect lone workers. A range of tools now exist to support monitoring, communication, and emergency response and many are cost-effective even for small businesses:
Lone worker apps: Smartphone apps allow workers to check in at intervals, trigger alerts if they don't respond, and send their GPS location to a monitoring centre or manager. Many include a panic button feature.
Dedicated lone worker devices: Wearable devices and purpose-built handsets that function even in areas with poor mobile signal. Some use satellite connectivity for truly remote environments.
Man-down and no-movement alerts: Devices that automatically raise an alarm if a worker falls, becomes incapacitated, or stops moving for an unusual period of time.
Two-way radios: Reliable in areas where mobile signal is poor, and useful for teams who work on-site but may be separated from colleagues.
Personal alarms: A simple, low-cost option that can deter aggression and attract attention in an emergency.
Check-in systems: Structured processes where lone workers contact a designated person at agreed intervals. Simple to implement and surprisingly effective as a baseline.
Vehicle tracking: For those who work on the road, GPS vehicle tracking ensures employers know where their drivers are and can raise the alarm if a vehicle stops unexpectedly.
The right solution will depend on the nature of your workforce and the environments they work in. A proper risk assessment will help identify which tools are most appropriate.
The Bottom Line
Lone working is a fact of modern working life. It spans industries, roles, and risk levels and it requires the same careful thought and management as any other health and safety issue.
The law is clear. The risks are real. And the solutions are more accessible than many employers realise.
Protecting a lone worker is not just a legal requirement, it is a statement of how much you value the people who represent your business, often in situations where no one else is watching.
Sarah deserved better. So does every lone worker in your organisation.
