Lone Worker Safety: UK Employer Responsibilities

An estimated 8 million people in the UK work alone at some point during their working week. From security guards and delivery drivers to estate agents, care workers and maintenance engineers, lone working is a reality across virtually every industry. Yet many employers remain unclear on their legal duties, assuming either that lone working is prohibited (it is not) or that no special precautions are needed (they are).

This guide sets out the UK legal framework for lone worker safety, explains how to carry out an effective lone working risk assessment, and describes the practical measures every employer should have in place.

What Is Lone Working?

There is no single legal definition of a lone worker, but the Health and Safety Executive (HSE) defines them as people who work by themselves without close or direct supervision. This includes:

• People who work in isolation from colleagues (e.g. a single employee in a shop, a security guard)
• People who work outside normal hours (e.g. cleaners, maintenance staff)
• Mobile workers whose workplace changes (e.g. delivery drivers, domiciliary care workers, engineers)
• Home workers (where their work involves risks beyond normal domestic activities)
• People working in remote or isolated locations (e.g. agricultural workers, forestry workers)

Lone working is not limited to working entirely alone. A nurse visiting a patient at home is a lone worker, even though the patient is present. An engineer working in a plant room is a lone worker, even though other people are in the building.

The Legal Framework

There is no specific lone working legislation in the UK. Instead, lone worker safety is governed by several overlapping pieces of legislation.

Health and Safety at Work etc. Act 1974

The Health and Safety at Work etc. Act 1974 (HSWA) is the primary piece of health and safety legislation in Great Britain. Section 2 places a general duty on every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all employees. This duty applies regardless of whether the employee works alone or alongside colleagues.

Section 3 extends this duty to anyone who is not an employee but may be affected by the employer’s undertaking — including contractors and members of the public.

Management of Health and Safety at Work Regulations 1999

The Management of Health and Safety at Work Regulations 1999 require employers to:

• Carry out a suitable and sufficient assessment of the risks to the health and safety of employees (Regulation 3)
• Make arrangements for the effective planning, organisation, control, monitoring and review of preventive and protective measures (Regulation 5)
• Appoint one or more competent persons to assist in undertaking the measures needed to comply with health and safety law (Regulation 7)
• Provide employees with comprehensible and relevant information on the risks identified and the measures in place (Regulation 10)

When the employee works alone, the risk assessment must specifically consider the additional risks arising from the absence of colleagues. This is not an optional extra — it is a core legal requirement.

Corporate Manslaughter and Corporate Homicide Act 2007

If a lone worker dies as a result of a gross breach of a duty of care owed by the employer, the organisation could face prosecution under the Corporate Manslaughter and Corporate Homicide Act 2007. Conviction carries unlimited fines and mandatory publicity orders.

Lone Working Risk Assessment

A lone working risk assessment follows the same HSE 5-step process as any risk assessment, but with a specific focus on the hazards that are increased or created by working alone. For a detailed guide to the general risk assessment process, see our article on how to write a risk assessment.

Hazards to Consider

When assessing the risks to lone workers, consider:

Violence and aggression — Lone workers who deal with the public face a higher risk of verbal abuse, threats and physical violence. This includes retail workers, care workers, housing officers, social workers, and anyone who visits people’s homes.

Medical emergencies — If a lone worker suffers a medical emergency (heart attack, seizure, severe allergic reaction), there may be no one available to call for help or administer first aid.

Accidents and injuries — A lone worker who is injured (e.g. a fall, being struck by an object) may be unable to summon assistance. The delay in receiving help can turn a survivable injury into a fatal one.

Mental health and stress — Working alone can be isolating. Lone workers may experience higher levels of stress and anxiety, particularly if they feel unsafe or unsupported.

Fire and emergencies — Lone workers may need to evacuate a building alone. They may not be able to raise the alarm or may not hear an alarm in a remote area.

Manual handling — Tasks that require two people for safety (e.g. moving heavy or awkward loads) should never be carried out by a lone worker.

Working at height — Falls from height are the most common cause of workplace fatalities in the UK. A lone worker who falls may be unable to call for help.

Confined spaces — The Confined Spaces Regulations 1997 specifically state that no person shall enter a confined space to carry out work unless there is a system of work in place that provides for rescue if needed. In most cases, this means lone working in confined spaces is not permissible.

Driving — Lone workers who drive for work face the usual road risks compounded by the absence of colleagues. Fatigue, in particular, is a significant risk for lone drivers.

Tasks Too Dangerous for Lone Workers

The HSE guidance is clear that some tasks should never be carried out by a person working alone. While there is no definitive list, the following should be considered:

• Entry into confined spaces — unless adequate rescue arrangements can be guaranteed
• Work near live electrical conductors — where a competent person must be present
• Work at height where the risk of a fall is significant and rescue would be delayed
• Work with highly dangerous substances where immediate emergency response is critical
• Any task where the risk assessment identifies that the presence of at least one other person is essential for safety

The test is whether the risk assessment shows that the work can be done safely by one person. If it cannot, you must either provide additional support or not carry out the task.

Practical Control Measures

Once you have identified the risks to your lone workers, implement appropriate control measures.

Communication and Check-In Systems

Reliable communication is the single most important safeguard for lone workers. Options include:

• Regular check-in calls — Lone workers contact a designated person at agreed intervals. If they fail to check in, an escalation procedure is triggered.
• Mobile phones — Effective in most situations, but consider signal coverage. Many rural or industrial locations have poor mobile coverage.
• Lone worker devices — Dedicated devices with GPS tracking, automatic fall detection, man-down alarms and SOS buttons. These devices can automatically raise an alarm if the worker does not move for a specified period or if the device detects a fall.
• Lone worker apps — Smartphone applications that provide similar features to dedicated devices, including timed sessions, check-in prompts, and GPS tracking.
• Buddy systems — Pairing lone workers so they can monitor each other, even remotely.

Monitoring and Supervision

While lone workers by definition work without close supervision, this does not mean they should receive no supervision at all:

• Ensure managers maintain regular contact with lone workers
• Conduct periodic site visits to check on working conditions
• Use technology to monitor worker safety (GPS tracking, automated alerts)
• Ensure lone workers know how to escalate concerns

Training

Lone workers often need additional training beyond what is provided to supervised employees:

• How to assess situations and identify risks
• How to de-escalate potentially violent situations
• First aid (a higher standard may be appropriate for lone workers)
• Emergency procedures — what to do if they are injured, taken ill, or face a fire
• How to use communication and monitoring equipment
• Understanding their limits — when to stop work and seek assistance

Safe Systems of Work

Develop procedures that specifically address lone working:

• Signing in and out — Ensure someone always knows where each lone worker is
• Itinerary sharing — Mobile workers should share their planned route and schedule
• Time limits — Set maximum periods for lone working in higher-risk situations
• Escalation procedures — Clear steps for what happens when a check-in is missed
• Emergency procedures — Tailored to the lone worker’s situation

Control of Violence

For lone workers at risk of violence:

• Train staff in conflict de-escalation techniques
• Provide information about known risks (e.g. previous violent incidents at an address)
• Consider personal protective alarms
• Ensure workers can leave the situation safely at any time
• Never expect lone workers to put themselves at risk to protect property
• Report all incidents, including verbal abuse, so patterns can be identified

RIDDOR and Lone Workers

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) apply to lone workers just as they do to any other employee. However, reporting can be more challenging when the employer is not immediately aware that an incident has occurred.

Ensure your lone working procedures include a mechanism for promptly identifying and reporting incidents that may be RIDDOR-reportable. A lone worker who is injured and unable to work for more than 7 days triggers a reporting obligation, whether or not the employer witnessed the incident. For full RIDDOR guidance, see our complete guide to RIDDOR reporting.

Industry-Specific Considerations

Social Care and Home Visits

Domiciliary care workers face a combination of lone working risks: violence from service users, manual handling of patients, driving between visits, and the emotional toll of isolated work. Employers must provide robust risk assessments for each service user, effective communication systems, and clear protocols for refusing entry to a property where a risk exists.

Retail

Shop workers who open or close premises alone, or work during quiet periods, are particularly vulnerable to robbery, violence and abuse. Consider CCTV, time-lock safes, panic buttons, and clear procedures for handling threatening situations.

Construction and Maintenance

Workers carrying out maintenance, inspections or repairs in isolated locations face risks from falls, equipment failure, and structural collapse. Never allow lone working in confined spaces. Ensure effective communication systems are in place, particularly in areas with poor mobile signal.

Agriculture and Forestry

Agricultural workers face some of the highest fatality rates of any occupation. Lone working with machinery, livestock and in remote locations requires particularly robust risk assessment and monitoring systems.

Security

Security guards by nature work alone, often at night, and face risks of violence, fire, and medical emergencies. Employers must provide communication systems, regular welfare checks, and training in conflict management.

What Employees Must Do

Lone worker safety is not solely the employer’s responsibility. Under the Health and Safety at Work etc. Act 1974, employees have a duty to:

• Take reasonable care of their own health and safety
• Cooperate with their employer’s safety arrangements
• Not interfere with or misuse anything provided for safety
• Report any hazards, incidents or concerns to their employer

Lone workers must follow the safe systems of work established by their employer, use the communication and monitoring equipment provided, and report any incidents or concerns promptly — even if they seem minor.

Building a Lone Working Policy

Every employer with lone workers should have a written lone working policy. This should include:

• A clear definition of lone working within your organisation
• The legal basis and your commitment to lone worker safety
• Responsibilities — of managers, supervisors and lone workers themselves
• Risk assessment procedures specific to lone working
• Communication and monitoring arrangements
• Training requirements
• Emergency and escalation procedures
• Incident reporting and investigation procedures
• Review arrangements — how often the policy will be reviewed

Managing Lone Worker Safety Digitally

Managing lone worker safety across an organisation — especially one with mobile workers, multiple sites, or shift patterns — requires robust systems. Paper-based sign-in sheets, manual check-in calls, and unrecorded risk assessments quickly become inadequate as your workforce grows.

Digital tools can provide real-time visibility of lone worker locations, automate check-in reminders, record risk assessments centrally, and ensure that training and policy acknowledgements are documented and up to date.
