Lone working in the workshop
Someone stays behind to finish a job in the evening. It is common, often reasonable — and one of the risks most often missing entirely from the risk assessment. Here is what the rules say and how a workshop solves it without it becoming a project.
Updated August 2026
What the rules say
Lone working is not prohibited. The provisions require the employer to assess the risks of lone working and arrange it so that someone working alone can get help if something happens.
Some work should not be done alone. Where there is a clear risk of an accident requiring immediate help, the work must be carried out by at least two people, or under supervision such that help arrives quickly.
The assessment is the employer's and must be written. An experienced fitter feeling it is fine is not the same as a risk assessment.
What is dangerous in a workshop specifically
Working under a raised vehicle is the clearest case. A vehicle on stands or a lift that gives way causes injury where minutes decide, and whoever is underneath can neither raise an alarm nor be seen.
Hot work alone is the second. A fire starting in an empty building is discovered late, and someone welding alone has nobody to interrupt them.
Heavy lifting and confined spaces. Trapping yourself between chassis and body sounds unlikely until it happens.
Electrical work and work with compressed air or pressurised hydraulics belong here too — energies that can release suddenly.
Practical solutions that work
The rule "never alone under a vehicle" is the single most effective measure, and costs nothing. It needs to be written down and to apply to the foreman as well.
Scheduled check-ins. Whoever works alone reports when they start and when they finish, to a named person. If the check-in does not come, you call. It sounds simple because it is.
An alarm that works where the work happens. A phone in the overall pocket is often enough, but not if it is on the bench ten metres away while you are under a vehicle.
Limit which tasks may be done alone rather than banning lone working outright. A list of what is permitted after closing is easier to follow than a blanket ban everyone works around anyway.
How to make the assessment
Start from the tasks, not the people. The question is which work requires immediate help if something goes wrong — not who is experienced enough to manage.
Include the time of day. The same task can be reasonable at three in the afternoon with colleagues around and unsuitable at nine in the evening.
Account for how long help takes to arrive. A workshop on an industrial estate with no neighbours has longer response times than one in town, and that must weigh in.
Write the conclusion down and make it known. An assessment sitting in a binder has changed nobody's behaviour.
Checklist
This is enough for most workshops.
- List the tasks that occur outside normal working hours.
- Assess which of them require immediate help if something goes wrong.
- Write a rule for what must never be done alone — working under a vehicle belongs there.
- Decide the check-in routine: to whom, when, and what happens if it does not come.
- Check that the alarm works where the work actually happens.
- Inform everyone, including those who rarely work alone.
- Include lone working in the ordinary risk assessment so it gets followed up.
Common questions
- Is lone working prohibited?
- No. It must be risk assessed and arranged so help can be reached. Some work with a clear accident risk should not be done alone.
- Is carrying a phone enough?
- Often, but not always. The question is whether an injured person can actually use it. Trapped under a vehicle, where the phone is makes no difference.
- Does it apply to the manager too?
- Yes. The rules apply to the work, not the job title, and a rule the foreman works around quickly stops applying to everyone else.
- How do we document it?
- As part of the risk assessment, with the tasks concerned and the conclusion for each. It does not need to be long — it needs to be written and known.

Keep the assessment alive
Risk assessments and measures with an owner and a date, linked to the safety rounds — so lone working comes up again next time instead of becoming a one-off note.
