What is Health and Safety Legislation? A Guide for UK SMEs

‍What is health and safety legislation? Health and safety legislation is the framework of UK laws and regulations that require employers to protect the health, safety and welfare of their employees and the public. The cornerstone is the Health and Safety at Work etc. Act 1974, supported by regulations such as those covering risk assessment, work at height, work equipment and lifting equipment safety, hazardous substances, incident reporting and workplace welfare. Fire safety legislation is also frequently covered by health and safety professionals.

‍

Every employee is entitled to work in an environment where the risks to their safety, health and welfare have been evaluated and suitably controlled. Every employer is legally required to keep their people and the public out of harm's way. However, many businesses don't fully deliver on their obligations under UK health and safety law. In 2024/25, 124 people were killed in work-related accidents and 1.9 million employees experienced a job-related illness (HSE, Annual Statistics 2024/25).

Health and safety legislation provides the structure and guidance to proactively protect your workers - and avoid the far-reaching costs of non-compliance. In addition to civil claims, reputational damage, and substantial financial penalties, workplace safety incidents can trigger personal criminal liability and imprisonment for company directors.

More positively, meeting and exceeding your legal requirements delivers a range of business benefits. Companies with robust compliance programmes enjoy reduced staff absence, deeper workforce engagement, and higher productivity - and research from the British Safety Council indicates that employee initiatives can deliver a twofold return on your investment.

A strong safety culture begins with a solid understanding of your duties as a responsible employer. This guide shares an overview of the UK's key health and safety (H&S) legislation - and how to weave compliance into everyday operations.

Key UK Health and Safety Legislation at a Glance

‍

The Health and Safety at Work etc. Act 1974: The UK's Primary Health and Safety Law

In the UK, the Health and Safety at Work etc. Act 1974 (HSWA) is the cornerstone of workplace safety law. This overarching piece of legislation requires employers to 'ensure, so far as is reasonably practicable, the health, safety, and welfare of employees and the public'. It also grants enforcement powers to the Health and Safety Executive.

The HSWA sets out the high-level safety duties for employers and staff - and is purposefully a broad, futureproof framework. It sits above supporting regulations that apply general principles to specific areas, such as workplace noise and hazardous substances. This hierarchy allows the government to introduce new safety requirements without rewriting the primary legislation.

Under the HSWA, you're required to:

• Minimise risks and maintain a safe working environment.
• Train your team to understand health and safety procedures.
• Adhere to safe systems of work and implement suitable safety controls.
• Make sure equipment is safe to use.
• Provide PPE and other appropriate safety equipment.
• Ensure all staff have access to suitable welfare provisions.

If you have five or more employees, you need to keep a written record of your health and safety policy and consult with your staff (or their representatives) on health and safety arrangements.

‍

The Management of Health and Safety at Work Regulations 1999: The Concept of Risk Assessment

If the HSW Act outlines the rules of workplace safety, the Management of Health and Safety at Work Regulations 1999 (MHSWR) explain how to implement them.

The MHSWR set out practical steps to create a safe working environment, supporting the HSW by diving into deeper detail. These regulations ensure you properly identify and control risks through essential tasks like assessments, training, and emergency procedures.

Key actions include:

• Appointing a suitably trained competent person to carry out your safety duties.
• Conducting thorough risk assessments for businesses.
• Implementing clear procedures for safety incidents and emergencies.
• Delivering staff training and information on workplace risks and safety controls.
• Providing employee health surveillance to track health risks over time.

‍

Workplace (Health, Safety and Welfare) Regulations 1992: Getting the Basics Right

Under the Workplace (Health, Safety and Welfare) Regulations 1992, every business owner is required to get the basics right - from toilets to traffic routes. The guidance ensures your team works in secure, sanitary surroundings, with suitable light, ventilation, hygiene measures, and eating areas.

To stay compliant, you should provide:

• Accessible, well-maintained hand-washing facilities, toilets (and showers, in some instances) that include clean hot and cold water, soap or other cleaning products, and a means of drying hands.
• Sufficient lighting to enable people to safely move and work without eyestrain.
• Clear floors and traffic routes, free of trip hazards and vehicle risks.
• A private place to change, if required. This should include clothes hooks, seating, and separate facilities for men and women.
• Clean, hygienic rest break facilities, with an adequate number of tables, a means to heat and eat food or drink, and a supply of clean drinking water.
• Ensure the workplace is organised in such a way that pedestrians and vehicles can circulate in a safe manner.
• Ensure floors in a workplace are suitable for the purpose for which it is used and where reasonably practical free slip and trip hazards.

RIDDOR: How and When to Report a Workplace Safety Incident

RIDDOR requires UK employers to report certain serious workplace accidents, occupational diseases, and near misses. The regulations outline a precise set of reportable incidents, spanning severe burns, noise-induced hearing loss, and electrical fires.

The regulations require you to report:

• The death of any person arising from a work-related accident.
• Specified injuries to workers, such as fractures (excluding fingers, thumbs, and toes).
• Injuries to workers that prevent them from performing their regular work duties for more than seven days.
• Injuries to non-workers where the injured person is taken directly to hospital from the scene for treatment.

You should always report incidents that genuinely meet RIDDOR criteria. However, submitting unnecessary reports can trigger costly consequences, such as inflated incident figures, increased regulatory scrutiny, and inconsistent safety processes.

Supplementary Health and Safety Regulations

While we've set out some of the core pillars of health and safety legislation, you'll need to adhere to additional regulations to protect your people and premises - and remain consistently compliant.

These include:

• Regulatory Reform (Fire Safety) Order 2005: Mandates fire risk assessments and a competent person to manage fire safety and implement safety measures.
• Health and Safety (Display Screen Equipment) Regulations 1992: Safeguard employees who use computers for a significant portion of their working week.
• Control of Substances Hazardous to Health (COSHH): Reduces exposure to materials that are harmful to health, including everyday chemicals like paint, bleach, cleaning products, and fine dusts from sanding or cutting.

Depending on your field, operations, and risk level, you may also need to align with specialist regulations.

• Manual Handling Operations Regulations 1992: Require employers to avoid hazardous manual handling where possible, assess risks that can't be avoided, and reduce the risk of injury. [INTERNAL LINK: Opus manual handling page]
• Work at Height Regulations 2005: Require employers to ensure work at height is properly planned, supervised and carried out by competent people. Falls from height remain one of the leading causes of workplace fatalities in the UK. [INTERNAL LINK: Opus work at height page]
• Personal Protective Equipment at Work Regulations 1992: Require employers to provide suitable PPE free of charge, ensure it fits properly, and train staff on its correct use. [INTERNAL LINK: Opus PPE page]
• Control of Noise at Work Regulations 2005: Limit workplace noise to protect employees' long-term hearing health.
• Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR): Control the risks to safety from fire, explosions, and substances corrosive to metals.
• Control of Asbestos Regulations 2012: Reduce exposure to asbestos-containing materials, often applying to landlords, facilities managers, and contractors.
