Risk assessments are the single most important document in UK health and safety law. They're not just paperwork—they're your legal proof that you've thought about how people could get hurt and what you're doing to prevent it.
But most risk assessments are useless. They sit in folders, never updated, full of generic copy-paste text that wouldn't help anyone stay safe.
This guide teaches you how to create risk assessments that actually work—organized in four layers, from the basics to advanced implementation.
The 4-Layer Framework
Layer 1
Foundations
Legal requirements, why assessments matter, basic definitions
Layer 2
Methodology
The HSE 5-step process, risk scoring, hazard identification
Layer 3
Templates
Practical templates, industry-specific examples, customization
Layer 4
Systems
Management systems, automation, continuous improvement
Each layer builds on the previous one.
Layer 1 gets you legal compliance. Layer 4 gets you a safety culture that prevents accidents before they happen.
Layer 1: The Foundations
Understanding why risk assessments exist and what the law actually requires.
What Is a Risk Assessment?
A risk assessment is a careful examination of what could cause harm to people in your workplace, so you can decide whether you've taken enough precautions or need to do more to prevent harm.
It's not about creating perfect safety (impossible). It's about reducing risks to a level that's "as low as reasonably practicable" (ALARP)—the exact wording used in UK law.
Key Legal Principle: ALARP
Risks must be reduced "as low as reasonably practicable." This means:
- If there's a control measure that's reasonably practicable, you must implement it
- Cost can be considered, but only if grossly disproportionate to the risk reduction
- Serious risks require more expensive controls than minor risks
- You can't argue cost alone when risks are high
The Legal Requirements
The main law is the Management of Health and Safety at Work Regulations 1999, Regulation 3. It requires every employer to:
- Make a suitable and sufficient assessment of risks to employees and others
- Identify measures needed to comply with health and safety law
- Record significant findings if employing 5+ people
- Review assessments when there's reason to suspect they're no longer valid
What "Suitable and Sufficient" Means
HSE says a suitable and sufficient risk assessment should:
- Identify the significant risks arising from or in connection with work
- Enable you to identify and prioritize measures to comply with relevant laws
- Be appropriate to the nature of the work and remain valid for a reasonable period
What Happens If You Don't Do It?
Penalties for failing to conduct risk assessments:
- Improvement notice: Requiring you to complete assessments within a deadline
- Prohibition notice: Stopping work immediately until hazards are controlled
- Prosecution: Unlimited fines in Crown Court, up to £20,000 in Magistrates' Court
- Imprisonment: Up to 2 years for serious breaches
- Director disqualification: Under Corporate Manslaughter Act
Who Should Conduct Risk Assessments?
As an employer, you are responsible for ensuring risk assessments are done. You can delegate the task, but not the responsibility.
The person conducting the assessment should be:
- Competent: Having sufficient training, experience, knowledge, and other qualities
- Familiar with the work: Understanding the tasks, processes, and equipment involved
- Impartial: Able to identify hazards objectively without production pressure
For complex or high-risk work, you may need an external consultant or occupational hygienist.
Common Misconceptions
❌ "We're too small to need risk assessments"
Wrong. Even one-person businesses must assess risks. You don't have to write them down if under 5 employees, but you still must do the assessment.
❌ "The template I downloaded is enough"
Generic templates are a starting point, not a finished product. Every workplace is different—your assessment must reflect YOUR actual hazards and controls.
❌ "Once written, it's done"
Risk assessments are living documents. They must be reviewed regularly and whenever there's significant change.
❌ "We can eliminate all risks"
Impossible. The goal is to reduce risks to as low as reasonably practicable, not zero. Some residual risk always remains.
Layer 2: The Methodology
The practical process of identifying hazards, assessing risks, and determining controls.
The HSE 5-Step Process
HSE recommends a 5-step approach to risk assessment. This is not legally mandated, but it's what inspectors expect to see:
Step 1: Identify the Hazards
Walk around your workplace and look for things that could reasonably cause harm. Consider:
- Slips, trips, and falls
- Moving machinery and vehicles
- Electricity
- Chemicals and hazardous substances
- Manual handling
- Work at height
- Noise and vibration
- Poor lighting or ventilation
- Fire and explosions
Sources of information: Manufacturer instructions, accident records, near-miss reports, worker feedback, HSE guidance, industry standards.
Step 2: Decide Who Might Be Harmed and How
For each hazard, identify:
- Who: Employees, contractors, visitors, members of the public, cleaners, maintenance staff
- How: Specific injury types (cuts, burns, broken bones, lung disease, hearing loss)
- Special groups: Young workers, new/expectant mothers, disabled workers, lone workers, shift workers
Step 3: Evaluate the Risks and Decide on Precautions
This is where you score the risk and determine what to do about it.
Risk Scoring: The 5x5 Matrix
Most UK businesses use a 5x5 risk matrix. You score two factors:
Likelihood (1-5):
- 1 - Rare: May occur only in exceptional circumstances
- 2 - Unlikely: Could occur sometime
- 3 - Possible: Might occur at some time
- 4 - Likely: Will probably occur in most circumstances
- 5 - Almost Certain: Expected to occur in most circumstances
Severity (1-5):
- 1 - Negligible: Very minor injury (scratch, bruise)
- 2 - Minor: First aid treatment required (small cut, minor sprain)
- 3 - Moderate: Medical treatment required (broken finger, minor burn)
- 4 - Major: Major injury (broken limb, serious burn, occupational disease)
- 5 - Catastrophic: Death or permanent disability
Risk Score = Likelihood × Severity
Risk Ratings:
- 1-4: Low risk (monitor, no additional controls needed)
- 5-9: Medium risk (implement controls within 3-6 months)
- 10-15: High risk (implement controls within 1-3 months)
- 16-25: Very high risk (stop work, implement controls immediately)
💡 Pro Tip:
Score the risk BEFORE controls (inherent risk) and AFTER controls (residual risk). This shows your controls are actually reducing risk.
Hierarchy of Controls
When selecting controls, use the hierarchy (most effective to least effective):
- Elimination: Remove the hazard entirely
- Substitution: Replace with something safer
- Engineering controls: Isolate people from the hazard (guards, barriers, ventilation)
- Administrative controls: Change how people work (training, procedures, signage)
- PPE: Protect the individual (last resort, least effective)
Step 4: Record Your Findings
If you employ 5+ people, you must write down:
- The significant hazards
- Who might be harmed
- What you're already doing
- What further action is needed
- Who needs to carry out the action
- When the action will be completed
Step 5: Review and Update
Review your assessment:
- At least annually
- After any incident or near miss
- When work activities change
- When new equipment or substances are introduced
- When new information about risks becomes available
Layer 3: The Templates
Practical templates you can use, customized for different industries and hazards.
Generic Risk Assessment Template Structure
Every risk assessment template should include these core sections:
Section 1: Assessment Information
- Activity/task being assessed
- Location
- Date of assessment
- Assessor name and signature
- Review date
- Reference number
Section 2: People at Risk
- Number of people exposed
- Job roles affected
- Any particularly vulnerable groups
Section 3: Hazard Identification and Risk Evaluation
Usually presented as a table with columns:
- Hazard description
- Who is at risk
- Existing control measures
- Likelihood score (1-5)
- Severity score (1-5)
- Initial risk rating
- Additional controls required
- Residual risk rating
Section 4: Action Plan
- Action required
- Person responsible
- Target completion date
- Actual completion date
- Verification/sign-off
Section 5: Communication and Training
- Who needs to be informed
- Training requirements
- Supervision requirements
Industry-Specific Templates
Different industries have different standard hazards. Here are template variations:
Construction Risk Assessment Template
Additional sections needed:
- Site location and access arrangements
- Plant and equipment register
- Permit to work requirements (confined spaces, hot work, etc.)
- Interface with other contractors
- Weather considerations
- Emergency procedures and first aid provision
Office Risk Assessment Template
Focused on:
- DSE (Display Screen Equipment) assessments
- Workstation setup and ergonomics
- Slips, trips on stairs and walkways
- Manual handling (filing, deliveries)
- Fire evacuation from multi-story buildings
- Lone working and out-of-hours access
Manufacturing Risk Assessment Template
Additional considerations:
- Machinery guarding and lockout/tagout
- Noise and vibration exposure levels
- Chemical exposure and COSHH assessments
- Repetitive tasks and ergonomic risks
- Fork lift truck operations
- Waste and scrap handling
Template Customization Is Critical
A template from the internet is a starting point, not a finished product. You must customize it for your specific workplace, equipment, people, and processes. Otherwise, it's legally worthless.
Layer 4: The Systems
Moving from individual assessments to a complete risk management system.
Building a Risk Assessment Management System
Individual assessments are important, but a systematic approach prevents them from becoming outdated filing cabinet fodder.
1. Assessment Register
Maintain a master register of all risk assessments:
- Reference number
- Assessment title
- Department/location
- Date completed
- Review date
- Status (current/overdue/in progress)
- Person responsible
2. Review Schedule
Set up automatic reminders for:
- Annual reviews (minimum)
- Post-incident reviews
- New starter assessments (young workers, new/expectant mothers)
- Equipment-specific reviews (after maintenance, modification)
3. Competency Framework
Ensure people conducting assessments are competent:
- Level 1: Supervisors can assess routine, well-understood tasks
- Level 2: Managers can assess more complex activities in their area
- Level 3: Health and safety specialists assess high-risk or complex operations
- External: Bring in consultants for specialized assessments (occupational hygiene, ergonomics)
4. Integration with Other Systems
Link risk assessments to:
- Method statements: Each RAMS combines RA with safe working method
- Training matrix: Identify training needs from control measures
- Inspection schedules: Equipment checks flow from identified risks
- Incident investigations: Update assessments after accidents
- Procurement: New equipment triggers assessment review

Continuous Improvement Cycle
Layer 4 thinking means treating risk assessment as a continuous improvement process, not a compliance checkbox:
Plan
Identify activities needing assessment. Schedule assessments. Assign competent assessors.
Do
Conduct assessments following 5-step process. Implement control measures. Train workers on controls.
Check
Monitor control effectiveness. Review incidents and near-misses. Conduct audits and inspections.
Act
Update assessments based on findings. Improve controls where needed. Share lessons learned.
Bringing It All Together
Each layer builds on the previous:
- Layer 1 gives you the legal foundation and understanding of why assessments matter
- Layer 2 provides the methodology to identify hazards and evaluate risks properly
- Layer 3 offers practical templates you can customize for your specific needs
- Layer 4 transforms assessments from documents into a living safety management system
Most businesses operate at Layer 1 or 2—meeting legal requirements but not leveraging risk assessment as a genuine safety tool.
Layer 4 organizations treat risk assessment as a continuous process that drives decisions, prevents accidents, and creates a culture where safety is genuinely valued.
