Lone Working in 2026: What UK Employers Must Get Right
More people are working alone than ever. Hybrid patterns have emptied offices at the edges of the day, lean staffing has left single operators covering night shifts, and mobile roles like care, maintenance, delivery, inspection, estate management have grown steadily. Lone working has quietly become one of the most common risk profiles in British workplaces, and one of the least well managed.
It's worth saying clearly at the outset: working alone is not against the law, and very often it's perfectly safe. There is no standalone “Lone Working Act.” What the law does require is that you assess the risks before someone works alone, and that your lone workers are not exposed to greater risk than anyone else.
Where the duty comes from
Your obligations sit in familiar places. Section 2 of the Health and Safety at Work etc. Act 1974 requires you to ensure the health, safety and welfare of employees so far as is reasonably practicable, and Section 3 extends that to people affected by your work, including contractors and the self-employed working for you. Regulation 3 of the Management of Health and Safety at Work Regulations 1999 requires a suitable and sufficient risk assessment, which must be recorded if you employ five or more people.
The HSE's guidance INDG73, Working alone, sets out what good practice looks like. It's short, free and worth reading in full but the essential questions it asks are these:
• Does the workplace itself present a special risk to someone on their own?
• Is there safe access and egress for one person?
• Can all the equipment, substances and loads involved be handled safely by one person?
• Is there a foreseeable risk of violence or aggression?
• Is the person medically fit to work alone, and are they sufficiently experienced?
• What happens if they are taken ill, injured, or simply don't check in?
If the honest answer to any of those is “we're not sure,” the work shouldn't start alone until it is.
The two failure modes that keep appearing
Recent HSE enforcement has highlighted two recurring patterns.
The first is machinery plus isolation plus solitude. In September 2026, a Merseyside animal feed manufacturer was fined £160,000 after a maintenance engineer's arm was pulled into an unguarded conveyor. He was working alone, and trapped in the machinery resorted to waving at a CCTV camera in the hope someone would see him. Everything about that case is a lone working lesson as much as a guarding one: high-risk maintenance, defeated protection, no second person, and monitoring that relied on somebody happening to look at a screen.
The second is vehicles and remote outdoor work. Also in September 2026, a farmer was fined following the death of an employee crushed under an overturned all-terrain vehicle. Agriculture, forestry, groundworks and estate maintenance combine isolation, terrain, vehicles and poor mobile signal make a demanding combination for any emergency response plan.
Practical controls that actually work
Set limits. Decide in advance which tasks may never be done alone: work at height, confined space entry, live electrical work, machinery maintenance requiring guard removal, and handling certain substances are common exclusions. Write the list down and make it non-negotiable.
Choose monitoring that doesn't rely on luck. Scheduled check-ins, a nominated responsible person, GPS-enabled lone worker devices with man-down alarms, or automated escalation if a check-in is missed. Whatever you choose, test it — including what happens at 3am on a bank holiday.
Plan for the emergency, not just the task. Who is called? How long until help physically arrives? Can an ambulance find the location? Does someone hold keys and access codes?
Take violence seriously. For anyone visiting homes, handling cash or dealing with the public, include conflict de-escalation training, pre-visit information sharing, and a clear right to withdraw. No employee should feel that leaving a hostile situation counts as failing at their job.
Don't forget health and wellbeing. Isolation affects mental health, and prolonged lone working can dull hazard awareness. Regular contact is a safety control, not just a courtesy.
Cover other people's premises. If your lone worker attends someone else's site, you must ask that employer about the risks and controls there — and they must tell you.
Getting started
If you don't currently have a lone working policy, start simply: list every role and situation where someone is out of sight or earshot of a colleague, rank them by consequence rather than frequency, and work through the highest first.
