Lone working is far more common than many employers realise. From staff opening premises early, to engineers visiting customer sites or employees working from home—many roles involve periods of working without close or direct supervision.
While it’s not illegal to work alone, employers have a legal duty to ensure that lone workers are not exposed to unnecessary risk. A lone working risk assessment is one of the most effective ways to meet this duty—and to protect both your employees and your business.
What is a lone working risk assessment?
A lone working risk assessment is a structured process used to identify hazards associated with working alone and determine what control measures are needed to reduce risk.
Its purpose is simple: to ensure that lone workers can carry out their duties safely, even without immediate support from colleagues or supervisors.

Why lone working increases risk
Lone workers face many of the same hazards as any other employee—but the consequences are often more severe. This is because there may be no one nearby to identify danger, help, or respond quickly in an emergency.
If something goes wrong, even a relatively minor issue—such as a slip, equipment fault, or confrontation—can escalate quickly without help on hand.
The Health and Safety Executive (HSE) highlights that lone workers are at greater risk because they lack direct supervision or immediate support if they become ill, injured, or involved in an incident.
Key reasons a lone working risk assessment is important
1. It helps you meet legal responsibilities
Under the Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations, employers must assess risks and take steps to protect workers—including those who work alone.
Failing to manage these risks appropriately can result in enforcement action, fines, or even prosecution in serious cases.
A suitable and sufficient risk assessment demonstrates that you are actively meeting your duty of care.
2. It identifies lone working-specific hazards
A dedicated assessment ensures you consider risks that may be overlooked in a general workplace assessment, such as:
Violence or aggression from the public
Delayed response to accidents or illness
Working in remote or isolated locations
Psychological risks such as stress or isolation
Medical suitability for working alone
By identifying these hazards early, you can put appropriate control measures in place.
3. It enables effective risk control
Once risks are identified, you can take practical steps to reduce them. These might include:
Implementing regular check-in procedures
Providing communication devices or lone worker alarms
Adjusting work tasks or scheduling
Ensuring adequate training, supervision, and support
Risk assessments allow you to move from reactive to proactive safety management—preventing incidents before they occur.
4. It protects employee wellbeing
Lone working can affect more than just physical safety. Employees who work in isolation may experience stress, anxiety, or reduced wellbeing.
Carrying out a thorough assessment allows employers to put measures in place that support both mental and physical health—such as regular contact, supervision, and clear emergency procedures.
It also ensures that individual risk factors are properly considered, including whether a worker is more vulnerable when working alone.
This may include employees who are:
Pregnant or new mothers, where emergency situations or fatigue may present additional risks
Living with medical conditions such as diabetes, epilepsy, or heart conditions, where delayed assistance could increase severity
Taking medication that may affect alertness or response
Experiencing mental health conditions that could be exacerbated by isolation
Considering personal factors as part of the risk assessment helps ensure that lone working is suitable for the individual, and that appropriate adjustments or controls are in place where needed as recommended by HSE guidance on assessing worker suitability to work alone.
This not only reduces risk but also improves employee morale, confidence, and productivity.
5. It reduces the severity of incidents
Without proper controls, incidents involving lone workers are more likely to result in serious harm due to delayed assistance.
A risk assessment helps ensure that workers can raise the alarm quickly, emergency procedures are clear, and that help is available when needed
This can make a critical difference in preventing minor incidents from becoming major ones.
6. It strengthens your business reputation
Businesses that take lone worker safety seriously are more likely to have better staff retention, attract relevant talent, and maintain client trust.
Demonstrating a proactive approach to Health & Safety shows that you value your employees—and that you operate responsibly and compliantly.
7. It ensures adequate first aid provision
First aid is a critical consideration for lone workers. Without colleagues nearby, even minor injuries or sudden illness can quickly become serious if help is delayed.
Employers must meet their legal duties by ensuring there are suitable arrangements in place—even for those working alone.
A lone working risk assessment helps determine what’s needed, such as personal first aid kits, basic training, reliable communication methods, and clear emergency procedures.
Where response times may be longer or risks are higher, lone working arrangements should be carefully reviewed to ensure workers are not left vulnerable when it matters most.
Common hazards faced by lone workers
Understanding the risks is central to any assessment. Typical hazards include:
Accidents or medical emergencies with no immediate assistance
Exposure to violence or challenging behaviour
Lack of access to welfare facilities
Working in unfamiliar or uncontrolled environments
Isolation and mental health concerns
Crucially, these risks are often made worse simply because the worker is alone.
Final thoughts
A lone working risk assessment isn’t just a legal requirement—it’s a practical tool for safeguarding your workforce.
By identifying hazards, implementing controls, and reviewing working practices, you can ensure lone workers are always protected—no matter where or how they work.
In today’s flexible and mobile working environments, taking a proactive approach to lone worker safety isn’t optional—it’s essential.
