The 'law' is a patchwork — that's the trap
Employers often go looking for the 'Lone Worker Act' and can't find it, then assume there's little to do. That's the mistake. The duties are real; they're just spread across general health-and-safety legislation rather than one tidy statute.
The two that matter most are the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999. Between them they place a clear, enforceable duty on you regarding anyone who works alone.
Your core duty as an employer
You must ensure, so far as is reasonably practicable, the health, safety and welfare of your employees — and you must assess the risks they face, including the risks that come specifically from working alone, and act on that assessment.
Lone working isn't banned. But if a role can't be done safely by one person on their own, the duty is to change how it's done — more controls, different arrangements, or not alone at all.
What 'reasonably practicable' really means
This is the phrase that decides most cases. It means weighing the risk against the time, cost and effort of controlling it — and doing what's proportionate. A high risk demands more; you can't skip a sensible, affordable safeguard just because it's slightly inconvenient.
In practice, for lone workers that almost always includes a reliable way to stay in contact, monitor welfare, and raise the alarm in an emergency. Where that's cheap and effective to provide, choosing not to is hard to defend.
When it goes wrong, the duty is what you're judged on
If a lone worker is seriously hurt, the questions come fast: did you assess the risk, did you have controls, could they raise the alarm, did help reach them. The answers determine liability — and in the worst cases, exposure under corporate manslaughter law.
Meeting the duty isn't only about avoiding penalties; it's about your people getting home. Vygard exists to make the 'raise the alarm and get help to them' part real — the practical control that turns a legal duty into an actual safety outcome.
Frequently asked questions
- Is there a specific lone worker law in the UK?
- No single act — the duties come mainly from the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999, which require you to assess and control the risks of working alone.
- Can an employee refuse to work alone?
- An employee can raise a genuine safety concern, and if a task can't be done safely alone you shouldn't require it. The employer's duty is to make sure lone work is safe or not done that way.
- What does 'so far as is reasonably practicable' mean?
- It means balancing the level of risk against the cost, time and effort of controlling it, and putting in place any control that isn't grossly disproportionate to the risk. For lone workers, a way to monitor welfare and raise the alarm usually clears that bar easily.
- What are the penalties for getting it wrong?
- Consequences range from improvement and prohibition notices to unlimited fines, and in the most serious cases individual or corporate liability — including under corporate manslaughter law where failures are gross.
