Lone Working: There's No Dedicated Law, But the Risk Assessment Duty Is Real

Lone working is one of the more commonly misunderstood areas of UK health and safety compliance, largely because employers go looking for a specific set of "lone working regulations" and don't find one. There isn't a standalone piece of legislation with that name. What exists instead is a clear duty under general health and safety law that applies just as fully to a lone worker as to anyone working alongside colleagues — the absence of a dedicated regulation is not the same as an absence of legal duty.

The legal basis

The duty to protect lone workers sits under the Health and Safety at Work etc. Act 1974, which places a general duty on employers to ensure, so far as is reasonably practicable, the health, safety and welfare of employees, and under the Management of Health and Safety at Work Regulations 1999, which require a suitable and sufficient risk assessment of the risks employees face while at work. Neither piece of legislation carves out an exception for people who happen to work alone — if anything, the absence of colleagues nearby to notice a problem or provide immediate assistance is itself a factor that a proper risk assessment has to take into account.

HSE's guidance document "Working Alone in Safety" is the standard reference point for how employers are expected to apply the general duty to lone working specifically, and it's the document most HSE inspectors and enforcement activity refer back to when assessing whether an employer's approach to lone working risk is adequate.

Who counts as a lone worker?

Lone working covers a broader range of situations than the phrase might first suggest. It includes people who work by themselves for all or most of their working day (a shopkeeper, a home visiting care worker), people who work outside normal hours (cleaners, security staff working night shifts when the rest of the workforce has gone home), mobile workers who travel between sites or work in the field, and people who work from home. The common thread is not job title but the absence of a colleague within immediate reach if something goes wrong — physical isolation, not a particular sector or role, is what triggers the need for a lone working risk assessment.

What the risk assessment must cover

Because the duty comes from the general risk assessment framework rather than a lone-working-specific regulation, the assessment needs to work through the actual circumstances of the role and identify what's different about doing it alone. Key questions HSE guidance points employers toward include:

• Can the work be done safely by one person at all? Some tasks — certain types of manual handling, some maintenance or confined space work — carry risks that genuinely require a second person present, regardless of how the rest of the role is structured.
• What happens if something goes wrong? Is there a means of raising an alarm or summoning help, and how quickly could help realistically arrive, particularly for remote or out-of-hours locations?
• Is there a reliable check-in system? A system for confirming a lone worker is safe at expected intervals — a scheduled call, a check-in app, a supervisor confirming end-of-shift contact — is one of the most commonly recommended controls, because it converts "nobody would know if something happened" into a bounded, known window of risk.
• Is the individual suited to working alone? This includes medical fitness, experience level, and training — a new or inexperienced worker may need a period of supervised work before being placed in a lone working situation that a more experienced colleague could manage safely.
• Are there specific violence or personal safety risks? For lone workers with public-facing duties, lone working risk overlaps directly with violence at work risk, since isolation is one of the factors that increases both the likelihood and the potential severity of a violent incident.

Why the "no dedicated law" point causes real gaps

In practice, the absence of a named lone working regulation leads some employers to treat lone working risk informally — relying on manager judgement or ad hoc arrangements — where they would treat a risk covered by a specifically named regulation (like manual handling or COSHH) with a documented, systematic assessment. The legal exposure is the same either way, since the general risk assessment duty applies with equal force. Employers get better outcomes, and a much stronger position if ever questioned by HSE, by giving lone working risk the same documented, reviewed treatment as any other assessed hazard, rather than treating it as a matter of common sense that doesn't need writing down.

Frequently asked questions

Is there a specific "Lone Working Regulations" law in the UK?

No. Lone working risk is covered by the general duties under the Health and Safety at Work Act 1974 and the risk assessment requirement in the Management of Health and Safety at Work Regulations 1999, not by a standalone lone-working-specific regulation.

Does working from home count as lone working?

Yes — home workers fall within the scope of lone working risk assessment, alongside mobile workers, people working outside normal hours, and anyone working by themselves for most of their working day.

What's the most commonly recommended control for lone working risk?

A reliable check-in system, so that a lone worker's safety is confirmed at known intervals rather than left unverified for an entire shift or visit.

The lack of a dedicated lone working law doesn't reduce the legal duty — it just means the duty has to be actively applied through the general risk assessment framework rather than found ready-made in a named regulation.
