The Health and Safety at Work etc. Act 1974 (HSWA 1974 or HASAWA) is the primary piece of legislation covering occupational health and safety in the UK. It sets out the general duties that employers have towards employees and the public, and that employees have to themselves and each other.
Are you familiar with your duties under the HSWA 1974?
Let's identify what you need to know.
What is the HSWA 1974?
The Health and Safety at Work etc. Act 1974 is the fundamental framework for health and safety law in the UK. It places general duties on:
- Employers — to protect workers and others affected by work activities
- Employees — to take care of their own safety and that of others
- Self-employed persons — to protect themselves and others
- Designers, manufacturers, and suppliers — to ensure products are safe
- Those in control of premises — to maintain safe working environments
The Act doesn't specify detailed requirements for every situation. Instead, it establishes broad principles and gives the power to create more specific regulations (like the Electricity at Work Regulations, Control of Substances Hazardous to Health, etc.).
The HSWA 1974 is "goal-setting" legislation. It tells you what you must achieve (safe workplaces) but often not exactly how to achieve it. This flexibility allows the law to apply to all types of workplaces, from offices to construction sites to chemical plants.
Why was the HSWA 1974 created?
Before 1974, UK health and safety law was a patchwork of outdated, industry-specific regulations. The system was:
- Fragmented — different rules for different industries, with gaps in coverage
- Reactive — focused on compensation after accidents rather than prevention
- Prescriptive — detailed rules that couldn't keep pace with technological change
- Ineffective — workplace injuries and deaths were unacceptably high
The Robens Report (1972)
The catalyst for change was the Robens Report, a government inquiry chaired by Lord Robens. Key findings:
- Too much law, but not enough action
- Self-regulation by industry was more effective than detailed rules
- Workers and their representatives should be involved in safety decisions
- A single framework law was needed to cover all workplaces
The HSWA 1974 was Parliament's response. It came into force on 1 April 1975 and has been the backbone of UK workplace safety ever since.
The 1974 Act was revolutionary for its time. It moved from "prescriptive" rules (telling you exactly what to do) to "goal-setting" principles (telling you what to achieve). This approach has been copied by many countries worldwide.
Key sections of the HSWA 1974
The Act is structured in sections, each covering different aspects of health and safety duties.
Section 2: Employer duties to employees
Section 2(1) is the core duty:
"It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees."
This breaks down into specific areas:
Section 2(2) specifies that employers must provide:
- Safe plant and systems of work — equipment and work processes must be safe
- Safe use, handling, storage, and transport of articles and substances — manage hazardous materials properly
- Information, instruction, training, and supervision — employees must know how to work safely
- Safe workplace with safe access and egress — the building itself and routes in and out must be safe
- Safe working environment with adequate welfare facilities — suitable conditions, toilets, washing facilities, rest areas
Section 2(3) requires larger employers (5+ employees) to:
- Prepare a written health and safety policy
- Bring the policy to employees' attention
- Review and update it as necessary
Section 2(4-7) covers:
- The right to safety representatives appointed by recognised trade unions
- The duty to consult with employee representatives
- The establishment of safety committees if requested
Manufacturing company fined £600,000 after worker loses fingers
A worker's hand was pulled into unguarded machinery during routine operation. Investigation revealed the company had no risk assessment for the machine and no safe system of work.
- ✗Machinery lacked adequate guarding
- ✗No risk assessment conducted
- ✗No safe system of work documented
- ✗Inadequate training for machine operators
- ✗Previous near-misses not investigated
- ✗Breach of Section 2(1) of the HSWA 1974
The company was prosecuted under Section 2 of the HSWA 1974. They were fined £600,000 plus £50,000 costs. The injured worker received a civil compensation settlement. The HSE inspector stated: 'This was entirely preventable and demonstrates a serious failure to manage basic workplace risks.'
Section 2 duties are not optional or aspirational. Employers must systematically identify risks, implement controls, and ensure safe systems of work are followed. The cost of non-compliance — in human and financial terms — far exceeds the cost of proper risk management.
Section 3: Duties to non-employees
Employers and self-employed persons must ensure their work activities do not put others at risk:
"It shall be the duty of every employer to conduct his undertaking in such a way as to ensure, so far as is reasonably practicable, that persons not in his employment who may be affected thereby are not thereby exposed to risks to their health or safety."
This applies to:
- Members of the public — people passing by or near your work activities
- Visitors — clients, customers, delivery drivers
- Contractors — those working on your premises but not employed by you
- Neighbouring businesses — others who might be affected by what you do
- Students, pupils, patients — in educational or healthcare settings
Section 3(2) requires self-employed persons to protect both themselves and others affected by their work.
Section 3(3) requires those who control premises to provide information about risks to non-employees.
Section 3 is why landlords, managing agents, and building owners have health and safety duties even if they don't employ anyone on site. If your activities (or the condition of your building) could harm others, you have a duty to manage those risks.
Section 4: Duties of those in control of premises
Those who control work premises have duties to people who are not their employees but use the premises:
- Ensure safe means of access and egress
- Ensure the premises and equipment are safe
- Ensure safe use of plant or substances provided
This section is particularly important for landlords, building owners, and managing agents.
Section 7: Employee duties
Employees are not just passive recipients of safety measures. They have active duties:
"It shall be the duty of every employee while at work—
(a) to take reasonable care for the health and safety of himself and of other persons who may be affected by his acts or omissions at work; and
(b) to co-operate with his employer or any other person so far as is necessary to enable that person to comply with any duty or requirement imposed on them under health and safety law."
In plain English:
- Look after yourself — don't take unnecessary risks
- Look after others — your actions affect colleagues and the public
- Follow instructions — use equipment and safety measures as you've been trained
- Co-operate — work with your employer's safety efforts, don't undermine them
- Report problems — tell your employer about hazards or defects
Section 7 means employees can be personally prosecuted for serious safety breaches. While rare, this has happened when individuals have recklessly endangered themselves or others, or deliberately ignored safety measures.
Section 8: Duty not to interfere or misuse
"No person shall intentionally or recklessly interfere with or misuse anything provided in the interests of health, safety or welfare."
This makes it an offence to:
- Tamper with safety guards on machinery
- Disable fire alarms or remove fire extinguishers
- Block fire exits
- Misuse safety equipment
- Remove or deface safety signs
This applies to everyone — employees, visitors, contractors, anyone.
Section 9: No charges for safety measures
Employers cannot charge employees for anything provided to comply with health and safety law:
- Personal protective equipment (PPE)
- Health surveillance (medical checks)
- Safety training
- Any other legally required safety measure
Who does the HSWA 1974 apply to?
Almost everyone
The Act applies across nearly all work sectors in Great Britain (England, Scotland, Wales):
- Employers (of any size, from sole traders to multinationals)
- Employees (full-time, part-time, temporary, contract workers)
- Self-employed persons
- Manufacturers, designers, suppliers, and importers of work equipment
- Those in control of premises where work is carried out
Limited exceptions
Very few workplaces are exempt:
- Domestic servants in private households
- Some activities covered by other specific legislation (e.g., some aspects of aviation, shipping)
Important: Even if you don't employ anyone, if you're self-employed or in control of premises, you likely have duties under the Act.
Who has duties under the HSWA 1974?
Employers' Duties
- •Ensure health, safety, welfare of employees (Section 2)
- •Protect non-employees affected by work (Section 3)
- •Written safety policy if 5+ employees
- •Provide information, instruction, training
- •Consult with employee safety representatives
- •Cannot charge for legally required PPE or safety measures
Employees' Duties
- •Take reasonable care for own safety (Section 7)
- •Take reasonable care for others' safety
- •Co-operate with employer on safety matters
- •Use equipment and safeguards properly
- •Not interfere with or misuse safety measures (Section 8)
- •Report hazards and defects promptly
Bottom line: Health and safety is a shared responsibility. Employers must provide safe systems and environments; employees must follow safe practices and co-operate. Both can be held accountable for failures.
"So far as is reasonably practicable"
This phrase appears throughout the HSWA 1974 and is critical to understanding your duties.
What does it mean?
"Reasonably practicable" is a balance between:
- The risk — the likelihood and severity of harm
- The sacrifice — the cost, time, and difficulty of measures to eliminate or reduce the risk
The test is: Is the risk significant enough that a reasonable person would take the action to reduce it, considering the cost and effort involved?
What it doesn't mean
- "As far as possible" — You don't have to do literally everything imaginable regardless of cost
- "As far as we can afford" — Cost can be considered, but only if it's grossly disproportionate to the risk
- "What we feel like doing" — It's an objective standard, not a subjective choice
The burden of proof
Importantly, in legal proceedings, if there's been a breach of duty, the burden is on the employer to prove that it was not reasonably practicable to do more. This is a reversal of the usual "innocent until proven guilty" approach.
"We couldn't afford it" is rarely an acceptable defence. If the risk is significant, and the control measures are standard practice in the industry, you'll be expected to implement them regardless of cost. Courts have held that only if the cost is "grossly disproportionate" to the risk can it justify not taking action.
Practical examples
Example 1: Working at height
Risk: Fall from 3m height, likely to cause serious injury or death.
Measures:
- Scaffolding costs £2,000
- Takes 1 day to erect
- Standard practice in the industry
Reasonably practicable? Yes. The risk is serious, the cost is proportionate, and it's standard practice. You must do it.
Example 2: Extremely rare risk
Risk: Meteor strike on office building (essentially zero probability)
Measures:
- Reinforced bunker would cost £500,000
- Would make building unusable for normal work
Reasonably practicable? No. The risk is so negligible that the cost and disruption would be grossly disproportionate.
Relationship to other health and safety regulations
The HSWA 1974 is the "parent" legislation. It gives the government power to create more specific regulations:
Regulations made under the HSWA 1974
These are detailed rules for specific hazards or situations:
- Management of Health and Safety at Work Regulations 1999 — requires risk assessments and management systems
- Workplace (Health, Safety and Welfare) Regulations 1992 — covers general workplace conditions
- Personal Protective Equipment at Work Regulations 1992 — requirements for PPE
- Manual Handling Operations Regulations 1992 — lifting and carrying
- Display Screen Equipment Regulations 1992 — workstations and computers
- Control of Substances Hazardous to Health Regulations 2002 (COSHH) — chemical and biological hazards
- Electricity at Work Regulations 1989 — electrical safety
- Gas Safety (Installation and Use) Regulations 1998 — gas appliances and fittings
- Regulatory Reform (Fire Safety) Order 2005 — fire safety (not made under HSWA but runs parallel to it)
- Control of Asbestos Regulations 2012 — managing asbestos risks
- Legionella Control (part of COSHH and Approved Codes of Practice) — water safety
How they work together
Think of it as a pyramid:
┌─────────────────────────────────────┐
│ HSWA 1974 (Broad principles) │
├─────────────────────────────────────┤
│ Regulations (Specific requirements)│
├─────────────────────────────────────┤
│ Approved Codes of Practice (Guidance)│
├─────────────────────────────────────┤
│ HSE Guidance (Best practice) │
└─────────────────────────────────────┘
- The HSWA 1974 sets the overall duty (e.g., "ensure safety")
- Regulations set specific requirements (e.g., "carry out a risk assessment")
- Approved Codes of Practice (ACOPs) provide detailed guidance (legal status: if you follow them, you're complying; if you don't, you must prove your alternative is equally effective)
- HSE Guidance offers practical advice (not legally binding but represents good practice)
Even if you comply with all specific regulations, you can still be prosecuted under the general duties in Sections 2 and 3 of the HSWA 1974 if something is unsafe. The Act provides a "catch-all" to cover risks not addressed by specific regulations.
Enforcement of the HSWA 1974
Who enforces it?
Two main bodies:
-
Health and Safety Executive (HSE) — enforces in:
- Factories and construction sites
- Mines, quarries, and offshore installations
- Farms
- Hospitals and schools
- Gas supply and distribution
- Nuclear installations
-
Local Authorities — enforce in:
- Shops and retail premises
- Offices
- Hotels and catering
- Leisure and consumer services
- Residential care homes
How is it enforced?
Inspectors have extensive powers under Sections 20-25 of the Act:
Powers of entry and inspection:
- Enter premises at any reasonable time (or any time if they believe there's danger)
- Bring police officers if they anticipate obstruction
- Take samples and photographs
- Examine documents and records
- Interview witnesses (with caution if potential prosecution)
Enforcement actions:
- Informal advice — for minor issues or where there's a willingness to improve
- Improvement Notice — requires you to remedy a breach within a specified time (minimum 21 days)
- Prohibition Notice — stops an activity immediately if there's a risk of serious personal injury
- Prosecution — for serious breaches or failure to comply with notices
Penalties for non-compliance
Magistrates' Court (summary offences):
- Fines up to £20,000 for most offences
- Up to 6 months imprisonment for some offences
Crown Court (indictment):
- Unlimited fines
- Up to 2 years imprisonment for breaches of Sections 2-6 or of improvement/prohibition notices
- Directors and senior managers can be personally prosecuted under Section 37 if the offence was committed with their consent, connivance, or due to their neglect
Construction director imprisoned for repeated safety failures
A construction company director was prosecuted after a worker fell through a fragile roof, suffering life-changing injuries. Investigation revealed this was the third serious incident in two years, and previous improvement notices had been ignored.
- ✗Work at height not properly planned or supervised
- ✗No edge protection or safety netting provided
- ✗Fragile roof not identified in risk assessment
- ✗Workers not trained on work at height procedures
- ✗Previous improvement notices not complied with
- ✗Director aware of risks but failed to take action
- ✗Section 2 and Section 37 breaches
The company was fined £400,000. The director was personally prosecuted under Section 37 for his consent/connivance in the offences. He received a 12-month prison sentence (6 months suspended) and was disqualified from being a company director for 5 years. The HSE inspector said: 'This was not an accident. It was a foreseeable consequence of systemic failures to manage well-known risks.'
Senior managers and directors can be held personally accountable. If you're in a position of authority, you must ensure health and safety is taken seriously. Ignoring warnings or enforcement notices is likely to result in personal prosecution and imprisonment.
Fees for intervention (FFI)
Since 2012, if HSE identifies a "material breach" of health and safety law, they can charge you for the time spent investigating and taking enforcement action. The current rate is around £163 per hour.
This applies from the moment the breach is identified until all necessary enforcement action is complete.
Modern relevance of the HSWA 1974
Still the foundation 50 years on
Despite being half a century old, the HSWA 1974 remains:
- Current — its goal-setting approach means it adapts to new workplaces and technologies
- Effective — workplace fatalities have fallen from around 650 per year in the mid-1970s to around 135 per year today (despite a much larger workforce)
- Comprehensive — it covers risks that didn't exist in 1974 (computer workstations, drones, modern chemicals, mental health)
Emerging areas
The principles of the HSWA 1974 are being applied to newer risks:
Mental health and psychosocial risks:
- Work-related stress, anxiety, and depression
- Bullying and harassment
- Workload and working hours
The duty under Section 2 to ensure employees' "health, safety and welfare" includes mental health. Employers must assess and manage psychosocial risks just as they would physical hazards.
Remote and hybrid working:
- Display screen equipment assessments for home offices
- Managing lone working risks
- Ensuring suitable working conditions in employees' homes
Section 2 duties extend to employees working remotely. While you can't control everything in an employee's home, you must do what is reasonably practicable to ensure their safety.
Gig economy and non-standard employment:
- Workers who aren't traditional employees still have protections
- Section 3 duties to contractors and self-employed persons
- Shared responsibilities in multi-employer situations
The HSWA 1974 is deliberately broad. "Health" includes physical and mental health. "Welfare" includes wellbeing. This means the Act can evolve with society's understanding of what "safety at work" means, without needing constant amendments.
Practical steps to comply with the HSWA 1974
For employers
1. Understand your general duty (Section 2)
- Ensure health, safety, and welfare of employees "so far as is reasonably practicable"

2. Carry out risk assessments
- Identify what could cause harm
- Decide who might be harmed and how
- Evaluate the risks and implement controls
- Record your findings (if 5+ employees)
- Review regularly
3. Implement control measures
- Follow the hierarchy of controls (eliminate, substitute, engineer, admin, PPE)
- Ensure measures are suitable and sufficient
- Maintain equipment and systems
4. Provide information, instruction, and training
- Induction training for new employees
- Job-specific training
- Refresher training as needed
- Clear instructions and safe systems of work
5. Consult with employees
- Safety representatives (if appointed by unions)
- Employee consultation (if no unions)
- Safety committees (if requested)
6. Prepare a written health and safety policy (if 5+ employees)
- Statement of intent
- Organisation (who does what)
- Arrangements (how you manage risks)
- Review and update annually or when things change
7. Protect non-employees (Section 3)
- Assess risks to visitors, contractors, public
- Provide necessary information and controls
- Co-ordinate with other duty holders
8. Monitor, review, and improve
- Regular inspections and audits

Look for trends, identify recurring issues, update risk assessments
Update policy, review all risk assessments, audit compliance
Update staff on procedures, new risks, lessons learned
Frequently asked questions
Yes. The Act applies to all employers regardless of size, including sole traders and micro-businesses. Some specific requirements are reduced for smaller employers (e.g., no written policy needed if fewer than 5 employees), but the fundamental duty to ensure health and safety remains the same.
Yes, under Section 7 (duties of employees) and Section 8 (not interfering with safety measures). However, prosecutions of employees are rare and usually reserved for serious breaches where the employee has recklessly endangered themselves or others despite clear instructions and training.
The HSWA 1974 is the parent Act that sets broad duties. The Management Regulations are made under the Act and provide specific requirements, particularly around risk assessment, management systems, and arrangements for health surveillance, training, and capabilities of employees.
Yes. The duty to ensure 'health' includes mental as well as physical health. Employers must assess and manage risks to mental health, including work-related stress, bullying, and excessive workload, just as they would physical hazards.
If you employ 5 or more people, yes — it's a legal requirement under Section 2(3) of the HSWA 1974. If you employ fewer than 5, you don't legally need a written policy, but it's still good practice to document your approach to health and safety.
It means you must weigh the risk against the sacrifice (cost, time, difficulty) needed to eliminate or reduce it. If the risk is significant and the measures are standard practice, you must implement them even if they're expensive. Only if the cost is grossly disproportionate to the risk can you justify not taking action.
Yes, under Section 37. If an offence by a company was committed with the consent, connivance, or due to neglect of a director or senior manager, that individual can be prosecuted personally. Penalties include fines, imprisonment, and disqualification from being a director.
Yes. Employers' duties under Section 2 extend to employees working from home. You must assess risks (e.g., DSE, manual handling, lone working) and do what is reasonably practicable to ensure their safety, although you can't control everything in an employee's home.
Since the Act came into force in 1975, fatal injuries to workers have fallen by over 80%, from around 650 per year to around 135 per year today, despite a much larger workforce. Non-fatal injuries have also declined significantly, though under-reporting remains an issue.
You must remedy the issue within the time specified (minimum 21 days). You can appeal to an employment tribunal within 21 days of receiving the notice, which suspends the notice pending the appeal. Failure to comply with an improvement notice is a criminal offence and can result in prosecution.
