How Risk Assessments Form Your Legal Defence
UK health and safety law doesn't expect employers to eliminate every conceivable risk — it expects them to do what's 'reasonably practicable' to control it. A genuine, up-to-date risk assessment is the clearest way to demonstrate that you've thought through the risks in your workplace and taken proportionate steps to address them.
What 'Reasonably Practicable' Really Means
In practice, this means weighing up the level of risk against the cost, time and effort of controlling it. A risk assessment is where this thinking happens — and is recorded. If something does go wrong, an investigator (or a court) will look at whether the risk was foreseeable, and whether the control measures in place were proportionate to it.
Common Gaps That Lead to Enforcement Action
Across many HSE investigations, similar patterns emerge:
- Working at height issues — falls remain a leading cause of serious injury, often linked to inadequate risk assessment of access equipment
- Manual handling — awkward lifts and repetitive movements that were never properly assessed
- Improvement notices ignored — where a known issue was identified but not acted on before an incident occurred
In each case, the common thread is the same: a risk assessment that either didn't exist, wasn't specific enough to the task, or wasn't followed up with action.
Making Risk Assessments Work in Practice
A risk assessment only provides real protection — legally and practically — if it's:
- Specific — covering the actual task, equipment and environment, not a generic template
- Acted on — control measures identified are actually put in place, not just listed
- Communicated — the people doing the work understand the risks and the controls that apply to them
- Reviewed — updated when the work, equipment, or environment changes
Training That Builds Competence
Courses such as Risk Assessment and the NEBOSH IIRSM Certificate in Managing Risk give managers and supervisors the skills to carry out assessments that genuinely reflect the work being done — not just complete a form. Essentials of Risk Management provides a broader introduction for those new to the topic.
Frequently Asked Questions
Does having a risk assessment guarantee I won't be prosecuted?
No — but a genuine, specific risk assessment that's been acted upon is strong evidence that reasonably practicable steps were taken, which is central to how breaches of UK health and safety law are judged.
What's the difference between a generic and a specific risk assessment?
A generic risk assessment covers common hazards for a type of task in broad terms. A specific risk assessment considers the actual equipment, environment and people involved — and is far more useful both for safety and for demonstrating compliance.
How often should high-risk activities be reassessed?
Whenever the task, equipment, environment or people involved change — and periodically even without an obvious change, particularly for activities like working at height and manual handling where the consequences of a gap can be severe.
