What is a Lone Worker? The Complete Employer Guide to Lone Working
Whether you manage a field sales team, community healthcare workers, engineers on remote sites, or delivery drivers, the chances are you employ lone workers - and with that comes a clear legal and moral duty of care.
This guide covers everything an employer needs to know: what lone working means, who counts as a lone worker, the legislation that applies, the risks involved, and how to build a robust lone worker policy that keeps your people safe.
What is a Lone Worker?
A lone worker is an employee who carries out their work in isolation from other workers, without close or direct supervision. This is the definition used by the Health and Safety Executive (HSE) and is the standard lone worker definition applied across UK workplaces.
Importantly, the definition of lone working is not simply about being physically alone. If an employee cannot be seen, heard, or reached by a colleague quickly enough to provide help in an emergency, they are a lone worker - even if they are technically on the same premises as others.
What is Lone Working in Practice?
The lone working definition is broader than most employers initially assume. A worker putting stock away in a back room, a nurse completing a home visit, or a security guard patrolling alone at night all fall under the definition of a lone worker.
Common examples of lone workers include:
- Field sales representatives visiting clients
- Community nurses, social workers and care workers
- Engineers and maintenance technicians on remote or unmanned sites
- Security staff on overnight shifts
- Drivers and delivery personnel
- Journalists, photographers and researchers working in the field
- Estate agents conducting property viewings
- Cleaners working outside standard office hours
- Construction workers in isolated areas
The lone working meaning is broader than it might first appear. It extends to any situation where a worker cannot readily access help whether because of where they are, when they are working, or the nature of the task itself.
If the environment, timing, or location means a colleague could not reach them quickly in an emergency, they are a lone worker.
Is it Legal to Work Alone?
Yes, working alone or solo working is not against the law in the UK. However, the law requires employers to carefully assess and manage the risks before allowing it. The HSE states that it will often be safe to work alone, but the legal obligation is on the employer to demonstrate this.
If a task is inherently too dangerous to carry out alone - transporting hazardous materials, for example - employers are legally required to ensure it is never assigned to a single worker.
Lone Working Legislation: What Applies?
There is no single lone working act in UK law, and there are no specific lone working laws applying only to lone workers. However, existing health and safety legislation applies fully to employees who work alone. Understanding which legislation is relevant to lone working is an important part of managing your duty of care.
Which Two Key Pieces of Legislation Apply to Lone Workers?
The two pieces of legislation most directly relevant to lone workers are:
-
The Health and Safety at Work Act 1974
This is the primary piece of lone working legislation UK employers must comply with. The Act places a duty on employers to ensure, so far as is reasonably practicable, the health, safety and welfare of all employees - including those working alone. This duty also extends to contractors and self-employed workers doing work for your organisation.
-
The Management of Health and Safety at Work Regulations 1999
Under these regulations, employers are required to carry out general risk assessments covering all employees, including lone workers. Businesses with five or more employees must record the significant findings. While a separate lone working risk assessment is not a legal requirement, lone workers must be considered within the organisation's overall risk assessment process.
These two pieces of legislation form the foundation of lone worker regulations in the UK. Together, they define employer obligations and the standard of care required for anyone working solo.
Other Relevant Lone Working Rules
Beyond these two primary pieces of lone working legislation, several other regulations may apply depending on sector and task:
- The Workplace (Health, Safety and Welfare) Regulations 1992 - workplace conditions
- The Provision and Use of Work Equipment Regulations 1998 (PUWER) - equipment safety
- The Manual Handling Operations Regulations 1992 - lifting and carrying tasks
- The Control of Substances Hazardous to Health Regulations 2002 (COSHH) - chemical exposure
There is no standalone lone working act in the UK statute book. Lone worker legislation is instead embedded across general health and safety law. The rules on lone working derive from these broader legal frameworks, not a single dedicated piece of legislation.
Health and Safety Lone Working: The HSE's Position
The HSE's guidance on health and safety lone working makes clear that employers must:
- Identify who their lone workers are
- Assess the risks they face
- Implement control measures to manage those risks
- Maintain regular contact with lone workers
- Ensure lone workers have a means of raising an alarm in an emergency
This forms the basis of lone working laws UK compliance.
Understanding the Risks of Lone Working
Effective lone working information starts with understanding what makes lone workers more vulnerable than those working in teams.
The primary risks include:
- Violence and aggression - particularly for public-facing roles. The British Crime Survey has indicated that lone workers face a disproportionate exposure to workplace violence.
- Medical emergencies - a sudden illness, seizure or injury with no colleague present to assist or call for help
- Accidents - slips, trips, falls or equipment failures with no immediate assistance available
- Mental health impact - isolation, stress, anxiety and feelings of disconnection from the team
- Environmental hazards - remote or unfamiliar locations with additional physical risks
Lone working regulations exist to ensure employers take these risks seriously and put proportionate measures in place.
The PET Risk Assessment Framework
A widely used framework for assessing lone worker risk is the PET methodology - a structured approach to understanding the risk profile of any lone worker. If you have ever wondered what does PET stand for in lone working or what does the acronym PET stand for in lone working, here is the answer.
PET stands for:
- P - People: Risks relating to the individuals the lone worker may encounter. Does the role involve contact with members of the public, service users with complex needs, or others who may present a risk?
- E - Environment: Risks associated with the location or setting. Is the worker in a remote, rural or isolated environment? Does the location itself present physical hazards?
- T - Task: Risks arising from the specific work being carried out. Does the task involve operating machinery, working at height, handling chemicals, or other inherently hazardous activities?
The PET framework helps employers tailor the level of protection and monitoring to the specific risk profile of each worker - recognising that a community nurse visiting a challenging service user has a very different risk profile from an engineer carrying out routine maintenance at a remote telecoms mast.
Lone Working Information: Building Your Lone Worker Policy
A lone worker policy is a written document that sets out how your organisation manages the safety of employees who work alone. While there is no specific legal requirement to have a standalone lone working policy, it is considered best practice and demonstrates compliance with your broader health and safety obligations.
What Should a Lone Worker Policy Include?
An effective lone worker policy should cover:
- The definition of a lone worker as used by your organisation
- The scope of roles and situations covered
- The responsibilities of employers, managers and the lone worker themselves
- Risk assessment procedures, including how lone workers are assessed using frameworks such as PET
- Communication protocols - how regularly workers check in and by what means
- What to do in an emergency - escalation procedures and response plans
- Prohibited activities - tasks that must never be completed alone
- Details of any lone worker technology in use (see below)
- Training requirements
- How the policy will be reviewed and updated
The policy should be accessible to all relevant employees, issued to new starters in applicable roles, and extended to contractors and temporary workers where appropriate.
