A practical guide to lone worker risk assessment, training and monitoring for UK employers
Millions of people across the UK work alone every day, from shop staff opening up before anyone else arrives, to engineers attending sites on their own, to care workers visiting clients’ homes. Lone working is a normal and often unavoidable part of modern business, but it brings a distinct set of health and safety risks that every employer has a legal duty to manage.
This article explains who counts as a lone worker, what the law requires, and the practical steps organisations should take, including risk assessment, training, supervision and monitoring, to keep people who work alone healthy, safe and supported.
Who Are Lone Workers?
A lone worker is anyone who carries out their job without close or direct supervision from colleagues. Lone workers exist in almost every sector and industry, and include people who:
- Work alone at a fixed base, such as a shop, petrol station, warehouse or leisure centre
- Work separately from colleagues on the same site, or outside normal hours, such as cleaners, security staff and maintenance engineers
- Work from home
- Work away from a fixed base entirely, including health, social care and home-visiting staff, construction and maintenance engineers, delivery and courier drivers, sales representatives, estate agents and agricultural or forestry workers
- Volunteer independently for a charity or community organisation, for example fundraising or litter-picking
Because lone workers face the same everyday workplace hazards as anyone else, but without a colleague nearby to help if something goes wrong, the consequences of an incident can be far more serious. That is why a robust approach to lone working risk assessment is essential.
Lone Working in the Gig Economy and Beyond
The way people work is changing. Automation, an ageing workforce and the rapid growth of the gig economy mean more people than ever are working independently, on-demand and via digital platforms, often as self-employed contractors or freelancers. Lone HGV drivers, van couriers and platform-based delivery workers, in particular, may face long and irregular hours, high physical and mental demands, and extended periods of isolation, all of which can affect their wellbeing if not properly managed.
The Legal Duty on Employers
Employers, and anyone who engages contractors, volunteers or self-employed people, have a legal responsibility for the health, safety and welfare of everyone who works for them, including those who work alone. This duty cannot be delegated or passed on to the lone worker themselves.
Under the Health and Safety at Work etc Act and the Management of Health and Safety at Work Regulations, employers must think about and control the risks of lone working before anyone is permitted to work unsupervised. While it will often be entirely safe to work alone, the law requires this to be a considered decision, backed by a documented lone worker risk assessment rather than an assumption.
Carrying Out a Lone Worker Risk Assessment
There is no separate legal requirement for a standalone lone working risk assessment; however, employers must include the specific risks of working alone within their general risk assessment process, and take proportionate steps to remove or control them. If you employ five or more people, your findings must be recorded in writing and reviewed regularly, particularly after any change to staff, processes, sites or equipment.
A thorough lone worker risk assessment should consider:
- The worker: their experience, training, and any factors that may increase vulnerability, such as being new to the role, young, pregnant, disabled or a trainee
- The environment and equipment: whether the site is remote or unfamiliar, whether the worker is entering someone else’s home or premises, whether entry and exit are safe outside normal hours, and whether the equipment can safely be operated by one person
- Communication: whether the worker has a reliable way to stay in contact and to summon help in an emergency
- The activity itself: whether the role carries a security function, involves handling cash or valuables, or otherwise carries an elevated risk of triggering an incident
Certain high-risk activities, such as confined space entry, work near exposed live electrical conductors, diving operations or work involving explosives, will always require at least one other suitably trained person to be present. Your risk assessment should identify these situations clearly and set out the level of supervision required for each task.
A properly documented lone working risk assessment is also one of the first things an HSE inspector, client auditor or insurer will ask to see, so keeping this current and evidence-based is a core part of demonstrating ongoing compliance.
Stress, Mental Health and Wellbeing
Working in isolation, away from the day-to-day support of colleagues and managers, can have a real impact on a lone worker’s mental health and stress levels. Reduced contact can leave people feeling disconnected or unsupported, which in turn can affect performance, wellbeing and safety.
Employers should put in place clear, regular channels of contact between lone workers and their managers, include lone workers in team meetings, training and social events wherever possible, and make sure managers are equipped to recognise early signs of stress or a change in normal behaviour. Where a lone worker has a pre-existing mental health condition, reasonable adjustments may be required in line with the Equality Act 2010.
Work-Related Violence and Personal Safety
Lone working does not automatically increase the likelihood of violence, but without a colleague close by, a lone worker may be more vulnerable if an incident does occur. Common risk factors include working in locations with a known history of violence, working late evenings or early mornings, holding a position of authority over customers or clients, contact with members of the public who may be under the influence of drugs or alcohol, and carrying cash or valuable equipment.
Practical control measures include personal safety and conflict-resolution training, sensible design of the working environment to avoid unnecessary isolation, and providing reliable alarm or check-in devices. Employers should also have a clear process for supporting any worker affected by a violent or abusive incident, and for recording and learning from what happened.
Language, Culture and Migrant Workers
Where a lone worker’s first language is not English, employers must ensure that instructions, training and emergency procedures are communicated clearly and are genuinely understood, not simply issued. Workers who are new to the UK may also be unfamiliar with local workplace culture and hazards, so additional induction, support and checking of understanding is often needed.
Medical Conditions and Emergency Planning
Where a worker has a medical condition, employers should seek appropriate medical advice and think through both routine tasks and foreseeable emergencies that could place extra physical or mental demands on that individual.
Every lone working arrangement should be backed by a clear emergency plan covering foreseeable events such as illness, injury, fire or equipment failure. Staff should be trained in these procedures and given the opportunity to practise them realistically. Depending on the risk assessment, some lone workers may need to carry first aid equipment, have first aid training (including self-administered first aid), and know exactly how and when to contact their employer in an emergency.
Lone Working From Home
Employers owe homeworkers the same duty of care as any other employee. This means providing appropriate supervision, training and control measures, and accepting the same liability for an accident or injury as would apply on a traditional worksite.
Training and Supervision for Lone Workers
Because lone workers cannot turn to a more experienced colleague in the moment, training and the right level of supervision are two of the most effective controls available to employers. Staff should be competent for the demands of their role, confident using any technical safety equipment provided, and clear on when and how to escalate for advice.
The right level of supervision is a management decision informed by risk assessment: the higher the risk, the greater the level of supervision required. Workers who are new to a role, undergoing training, facing an unfamiliar situation, or carrying out a task with specific risks may need to be accompanied initially, before being signed off to work alone.
Investing in structured lone working training helps organisations demonstrate compliance, reduce incidents and build a genuinely safety-conscious culture. CompliSafe’s online training courses cover lone working awareness, personal safety, dynamic risk assessment and emergency response, and can be completed flexibly by staff working across multiple sites or on the road.
Monitoring and Keeping in Touch
A wide range of technology and systems now exists to help employers monitor lone workers and maintain contact, but any system is only effective if it is properly embedded, understood and tested. Options include periodic supervisor visits, pre-agreed check-in intervals by phone, radio or app, manual or automatic alarm devices, and a reliable process to confirm a lone worker has safely returned to base once their task is complete. Technical solutions and emergency procedures should be tested regularly to ensure they work when needed.
Dynamic Risk Assessment and Workers’ Responsibilities
All workers have a duty to take reasonable care of their own health and safety, and that of anyone else affected by their work, and to co-operate with their employer’s health and safety arrangements. Where a formal risk assessment identifies that a lone worker may need to make an on-the-spot, or ‘dynamic’, risk assessment in the field, that worker must be trained in how to do so, understand the range of control measures available, and know how to get support for the decisions they make. Dynamic risk assessment is a valuable additional tool, but it is never a substitute for thorough, documented planning in advance.
Self-Employed and Contract Lone Workers
Self-employed workers are not always automatically covered by the same health and safety duties, but where an organisation engages a self-employed person or contractor to work on its premises or as part of its operations, it generally remains responsible for that individual’s health and safety, in the same way as for any other lone worker.
