What are the risk assessment requirements for lone working?

Updated · UK law and HSE guidance

Short answer

Employers must manage risks to lone workers under the Management Regulations. Assess how working without nearby help changes foreseeable harm, then provide suitable training, supervision, monitoring, contact and emergency response. Lone working is not generally prohibited, but some high-risk activities require another person or specific rescue and supervision arrangements.

Assess what changes when someone is alone

Start with the hazards of the job, then consider delayed assistance, communication, isolation and the worker's ability to deal with foreseeable events. Include violence, stress, medical suitability, travel, remote locations and work at another employer's premises. Consult the worker and obtain information about host-site risks and controls where relevant. Do not use a generic lone-worker label as the assessment.

  • Identify who knows the worker's location and task
  • Consider foreseeable loss of signal, power or transport
  • Decide which activities must not be performed alone

Match monitoring to the risk

Set check-in frequency and escalation from the risk, not convenience. Options include scheduled calls, supervisor visits, automatic alerts or monitored devices, but equipment is useful only if coverage, charging and response are reliable. Define who responds, how quickly and what they do after a missed contact or alarm. Avoid relying solely on the lone worker to rescue themselves.

  • Test the communication and escalation arrangements
  • Provide clear emergency and first-aid information
  • Increase supervision for new, inexperienced or higher-risk workers

Train, review and support

Training should cover the work, limits of authority, use of communication equipment, violence prevention and when to stop. Supervisors need enough information to notice missed contacts and changing risk. Review after incidents, changes, concerns or evidence that the system failed. Home and hybrid workers require suitable assessment and controls too. Practise the emergency response at suitable intervals and learn from each exercise. SitePaper can generate a lone-working risk-assessment draft for competent review.

  • Confirm workers can raise concerns without pressure
  • Record deviations and learn from alarms
  • Keep personal and medical information proportionate and secure
