Health & Safety at Work

Every employee in the United Kingdom has the right to a safe workplace. The health and safety at work act — the Health and Safety at Work Act 1974 — is the law that makes that right real. It places broad duties on employers to protect the health, safety and welfare of their staff, gives employees important responsibilities of their own, and arms the Health and Safety Executive (HSE) with strong enforcement powers. Whether you are an employer working out what compliance requires, or an employee worried about unsafe conditions, this guide explains the essential health and safety at work legislation, how it is enforced, what to do after an accident, and where the rules overlap with employment tribunals and personal injury claims.

What Is the Health and Safety at Work Act?

The Health and Safety at Work Act 1974, often shortened to HSWA, is the primary statute regulating health and safety in workplaces across Great Britain. Before 1974, safety was governed by a patchwork of industry-specific rules; the health and safety at work act replaced them with a single framework of broad, goal-setting duties that apply to almost every employer.

What law regulates health and safety in the workplace beyond the Act itself? A large body of regulations made under it — on risk assessments, manual handling, display screen equipment and hazardous substances — provides the detail. The most important are the Management of Health and Safety at Work Regulations 1999, covered below.

The Act’s duties apply “so far as is reasonably practicable”: the law balances the seriousness of a risk against the cost and effort of preventing it. An employer that did everything reasonably practicable has discharged its duty; one that cut corners to save money has not.

Employer Duties Under the Health and Safety at Work Act

Section 2 of the health and safety at work act requires every employer to ensure, so far as is reasonably practicable, the health, safety and welfare of its employees. In practice this means:

• Providing and maintaining plant and systems of work that are safe and without risks to health.
• Ensuring the safe use, handling, storage and transport of articles and substances.
• Providing the information, instruction, training and supervision employees need to work safely.
• Maintaining a safe workplace with safe means of entry and exit.
• Providing a safe working environment with adequate welfare facilities.

Employers with five or more employees must also prepare a written health and safety policy, keep it current and bring it to the notice of staff. And section 9 forbids charging employees for anything done to meet these duties — staff can never be asked to pay for their own safety training or protective equipment.

The Management of Health and Safety at Work Regulations 1999

The management of health and safety at work regulations turn the Act’s broad duties into concrete management steps. The Management of Health and Safety at Work Regulations 1999 apply to every employer, and their cornerstone is the risk assessment.

Regulation 3 requires a suitable and sufficient assessment of the risks to employees and anyone else affected by the business, with significant findings recorded where five or more people are employed. It must be a living document: reviewed when circumstances change and turned into real control measures.

The management of health and safety at work regs also require employers to:

• Make effective arrangements for planning, monitoring and reviewing protective measures.
• Appoint competent persons to help meet health and safety duties.
• Establish procedures for serious and imminent danger.
• Give employees comprehensible health and safety information and adequate training.

Young workers need particular attention, and new and expectant mothers are entitled to specific risk assessments and adjustments.

Employee Duties Under the Act

Health and safety is a shared responsibility. Sections 7 and 8 of the health and safety at work act require every employee to take reasonable care of their own health and safety and that of others affected by their work, and to cooperate with the employer so far as necessary. It is also an offence to intentionally or recklessly interfere with anything provided for health, safety or welfare — such as removing a machine guard.

In practice: follow your training, use protective equipment as instructed and report hazards promptly. An employee who ignores clear safety instructions can face disciplinary action — but workers who raise genuine concerns are strongly protected, as explained below.

HSE Enforcement: Improvement and Prohibition Notices

The Health and Safety Executive (HSE) — and local authorities for lower-risk workplaces such as shops and offices — enforces the health and safety at work act. Inspectors may enter premises without an appointment, inspect, take samples and photographs, require documents and question people on site.

Where a breach is found, an improvement notice can require it to be fixed within a set period (usually at least 21 days), while a prohibition notice stops a dangerous activity immediately where there is a risk of serious personal injury.

Serious breaches lead to prosecution in the magistrates’ or Crown Court: unlimited fines, scaled to the organisation’s turnover so large employers face millions of pounds, and up to two years’ imprisonment for individuals.

Reporting Accidents: RIDDOR

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) oblige employers and those in control of premises to report certain incidents to the HSE:

• Deaths and specified injuries to workers, such as fractures, amputations and serious burns.
• Injuries keeping a worker off normal duties for more than seven days.
• Diagnosed occupational diseases, such as occupational asthma.
• Dangerous occurrences — near misses with the potential to cause serious injury.

Fatal and specified injuries must be notified by the quickest practicable means with a full report within 10 days; other incidents go through the HSE’s online system. Records must be kept for three years, and failing to report is itself an offence.

Raising Safety Concerns: Protection Against Dismissal and Detriment

Workers who speak up about safety enjoy some of the strongest protection in UK employment law — because a workplace where people fear raising concerns is a dangerous one.

A dismissal is automatically unfair where the reason is health and safety related. Section 100 of the Employment Rights Act 1996 protects employees who carry out safety activities, raise concerns about risks, or leave the workplace in circumstances of danger they reasonably believe to be serious and imminent. Our guide to unfair dismissal explains how these claims work.

There is no minimum length of service for these claims and compensation is not subject to the usual statutory cap. Employees are also protected from detriment — such as worse shifts or blocked promotion — for raising safety concerns, and a disclosure about a health and safety danger can be a protected whistleblowing disclosure with further rights against dismissal.

Personal Injury and Employers’ Liability Claims

Alongside the health and safety at work act’s enforcement regime sits the civil law. An employee injured through an employer’s negligence or breach of statutory duty can claim compensation for pain and suffering, lost earnings and care costs — usually in the county court, and generally within three years of the accident.

Employers must hold employers’ liability insurance of at least £5 million, so an insurer normally meets successful claims. Prevention, though, remains far better than compensation for everyone involved.

When Health and Safety Reaches the Employment Tribunal

Health and safety disputes regularly reach the employment tribunal: automatically unfair dismissal claims under section 100, detriment claims for raising concerns, whistleblowing claims about safety disclosures — and constructive dismissal where an employee resigns over ignored dangers.

There can be overlap with discrimination law too. Where a disabled employee needs adjustments to work safely, failing to make them may breach both safety duties and equality law — see our workplace discrimination guide.

A Practical Compliance Checklist for Employers

Treat safety as an ongoing process, not a one-off exercise:

• Carry out suitable and sufficient risk assessments, record the findings and review them regularly.
• Maintain a written health and safety policy (mandatory with five or more employees) and communicate it.
• Provide induction and ongoing training, instruction and supervision.
• Supply personal protective equipment free of charge where risks cannot be controlled another way.
• Consult employees or their safety representatives on safety matters.
• Appoint competent persons, plan for emergencies and report incidents under RIDDOR.
• Build a culture where concerns can be raised without fear — and act on them promptly.

What to Do If You Face Unsafe Conditions or Are Injured

If you are worried about safety at work:

• Report the hazard to your manager or safety representative in writing and keep a copy.
• If the danger is serious and imminent, you may leave the area — the law protects you from dismissal or detriment.
• Keep your own record: dates, times, who was told, photographs and witness names.
• If injured, get medical attention, ensure the accident is entered in the accident book and check RIDDOR reporting.
• Get advice early — strict time limits apply to tribunal claims and personal injury actions.

Knowing the health and safety at work legislation is the first step to enforcing it. The law stands firmly behind workers who act reasonably to protect themselves and others.
