Why lone workers need more training than colleagues who work alongside others, what that training should cover, how much supervision is needed, and the systems for keeping in touch.
The short answer
There is no named, mandatory lone worker qualification. But HSE is clear that employers must train, supervise and monitor lone workers, keep in touch with them and respond to any incident. Because lone workers usually cannot ask a more experienced colleague for help, extra training may be appropriate, and it should be relevant to the work they actually do. For who counts as a lone worker and what the risk assessment must cover, see our lone working guide.
Why Lone Workers Need Extra Training
Lone workers need to be sufficiently experienced and to fully understand the risks and precautions involved in their work and in the location they work in. HSE says training is important:
- where there is limited supervision to control, guide and help in uncertain situations
- in enabling people to cope in unexpected circumstances, and with potential exposure to violence and aggression
Instruction, training and supervision are also among the things HSE says the risk assessment must include for lone workers, so training is part of the legal duty rather than an optional extra.
What Lone Worker Training Should Cover
Employers should set the limits to what can and cannot be done while working alone, and make sure workers are competent to deal with the requirements of the job, suitably trained in any technical solutions provided and able to recognise when to seek advice. In practice that gives training six jobs to do.
The risks of the job
The hazards in the work and the location, and the precautions for each, so the worker understands why the rules exist.
The limits of working alone
Which tasks can be done alone and which cannot, and the point at which work should stop.
When to seek advice
Recognising a situation that is beyond their training or authority, and who to contact.
The systems you use
Check-in procedures, phones, radios and any device for raising the alarm, and what happens when a check-in is missed.
Personal safety
Recognising situations where they may be at risk of violence or aggression and the steps to avoid or manage it. HSE notes this may include conflict resolution.
Emergencies
The emergency procedures, practised regularly and realistically, including how and when to contact the employer, and first aid where the risk assessment calls for it.
Dynamic Risk Assessment
Some employers rely on lone workers making operational decisions on the spot about risks that could not be foreseen. HSE is clear that this is not a substitute for a comprehensive risk assessment. Where your assessment identifies circumstances in which a lone worker may have to make a dynamic risk assessment, they must:
- receive training on how to make that assessment
- consider the range of possible control measures and what action to take
- get support for their decisions
Supervision
The extent of supervision depends on the risks involved and the lone worker’s ability to identify and handle health and safety issues. It is a management decision that should be based on the risk assessment: the higher the risk, the greater the level of supervision. HSE says lone workers may need to be accompanied at first where they are:
- new to a job
- undergoing training
- doing a job that presents specific risks
- dealing with new situations
Monitoring and Keeping in Touch
Any monitoring system needs to be embedded in the organisation so that workers understand it well, and you must put clear procedures in place. These may include:
- supervisors periodically visiting and observing people working alone
- pre-agreed intervals of regular contact by phone, radio or email, bearing in mind the worker’s understanding of English
- devices designed to raise the alarm in an emergency, operated manually or automatically
- a robust system to make sure a lone worker has returned to their base or home once their work is completed
Test technical solutions and all emergency procedures regularly, so you know lone workers can be reached if a problem or emergency is identified.
When a worker’s first language is not English
You must ensure workers have received and understood the information, instruction and training they need to work safely. Make sure suitable arrangements are in place for clear communication, especially in an emergency. Workers from outside the UK may also meet unfamiliar risks and a workplace culture very different from the one they are used to.

Frequently Asked Questions
Is lone worker training a legal requirement?
There is no named, mandatory lone worker qualification. But employers must manage the risk to lone workers, and HSE states that this means you must train, supervise and monitor them. Instruction, training and supervision are among the things the risk assessment must include.
What should lone worker training include?
It should be relevant to the work activity. HSE expects lone workers to understand the risks and precautions in their work and location, to know the limits of what can be done alone, to be trained in any technical solutions provided and to recognise when to seek advice. Personal safety training, which may include conflict resolution, helps with the risk of violence.
Do new lone workers need to be supervised?
HSE says lone workers may need to be accompanied at first where they are new to a job, undergoing training, doing a job with specific risks or dealing with new situations.
How often should lone workers be contacted?
HSE does not set a fixed interval. It expects pre-agreed intervals of regular contact, together with a robust system to make sure the worker has returned to their base or home once the work is completed.
Do lone workers need first aid training?
It depends on the risk assessment. HSE says the assessment may indicate that some lone workers should carry first aid equipment or need first aid training, including how to administer first aid to themselves.
