Is lone working legal in the UK?
Short answer: yes — there is no general ban on working alone. The catch is that the employer has to assess and control the risks first. Here is what the law actually requires.
There is no ban — but there is a duty
No law says people cannot work alone. What the law does say is that an employer must protect the health and safety of workers and anyone affected by the work. Applied to lone working, that means deciding whether the work can be done safely by one person, and if so, putting the right arrangements in place.
In Great Britain the duties come from the Health and Safety at Work etc. Act 1974 (the general duty of care) and the Management of Health and Safety at Work Regulations 1999 (the duty to make a suitable and sufficient assessment of the risks). In Northern Ireland the equivalents are the Health and Safety at Work (Northern Ireland) Order 1978 and the Management of Health and Safety at Work Regulations (Northern Ireland) 2000.
No separate lone-worker risk assessment is required
A common myth is that the law demands a standalone "lone-worker risk assessment" document. It does not. Lone-working risks can be assessed within your general risk assessment — what matters is that the risks of working alone are genuinely considered and controlled, not the format of the paperwork. See how to assess lone-working risk.
When working alone isn't appropriate
Sometimes the assessment will conclude that a task should not be done alone. Certain confined-space entry, some high-risk work, and specific activities where the law or a safe system of work requires more than one person are examples. Where that is the case, the answer is not a better check-in arrangement — it is not doing that task alone.

Is it legal to work alone?
Yes. There is no general legal ban on working alone in the UK. But the employer must manage the health and safety risks of lone working before someone works alone — assessing whether the work can be done safely by one person, and putting controls in place where needed.
Do I need a separate lone-worker risk assessment?
There is no legal requirement for a standalone lone-worker risk assessment document. Lone-working risks can be assessed within your general risk assessment under the Management Regulations. What matters is that the lone-working risks are actually assessed and controlled — not the format of the paperwork.
Which laws apply?
In Great Britain, the Health and Safety at Work etc. Act 1974 (the general duty to protect workers and others) and the Management of Health and Safety at Work Regulations 1999 (the duty to assess risk). In Northern Ireland, the Health and Safety at Work (Northern Ireland) Order 1978 and the Management of Health and Safety at Work Regulations (Northern Ireland) 2000.
Is some work unsuitable for lone working?
Yes. A risk assessment may conclude that certain work should not be done alone — for example some confined-space entry or particular high-risk tasks — and specific regulations can require more than one person. Where that is the case, lone working for that task is not appropriate.
