The 5 Steps of a Risk Assessment

Every employer and self-employed person in the UK has a legal duty to assess the risks in their work. The HSE sets out a simple, five-step approach — you don't need to be a safety expert to understand it.

Step 1 — Identify the hazards

Walk through your work and spot anything with the potential to cause harm: chemicals, working at height, slips and trips, manual handling, electrical equipment, dust, and so on. Ask your team — they often notice things you don't.

Step 2 — Decide who might be harmed and how

For each hazard, identify who could be affected — staff, contractors, visitors, members of the public — and how the harm might happen. Some groups need extra thought, such as new or young workers, expectant mothers and lone workers.

Step 3 — Evaluate the risks and decide on controls

Judge how likely harm is and how serious it could be, then decide what to do about it. The law expects you to do everything "reasonably practicable" to control risk — following the hierarchy of control: remove the hazard if you can, and if not, reduce, isolate or protect against it.

Step 4 — Record your findings

Write down the significant hazards, who is at risk and the controls you've put in place. If you employ five or more people, recording your assessment is a legal requirement. Even if you have fewer, a written record is strong evidence that you've met your duty.

Step 5 — Review and update

A risk assessment is a living document. Review it regularly and whenever something changes — new equipment, a new process, an accident or near-miss, or a change in how you work.

Quick reminders

  • 5+ employees = you must record it in writing
  • It must be "suitable and sufficient" — specific to your work
  • Review after any significant change or incident
  • A template alone rarely passes — it has to reflect reality
General guidance only. A risk assessment must be specific to your tasks and workplace to be valid. AB SiteSafe writes bespoke, HSE-aligned risk assessments built around your actual work.
