Health and Safety at Work in the United Kingdom

What is this right?
The Health and Safety at Work etc. Act 1974 grew out of the Robens Report after a string of post-war industrial disasters. Half a century later, it's still the umbrella statute. Section 2 imposes the master duty: every employer must, so far as is reasonably practicable, ensure the health, safety, and welfare of their employees. In practice that means:
- Carry out risk assessments and act on what they find
- Provide a safe working environment — proper equipment, ventilation, lighting, temperature
- Provide information, instruction, training, and supervision
- Provide adequate welfare facilities — toilets, washing, drinking water, rest areas
- Have a written health and safety policy if they employ 5 or more people
Workers carry duties too — you have to take reasonable care of your own safety, and not actively undermine the controls your employer has put in place.
When does it apply?
- Covers all workers — employees, agency workers, trainees, and (under section 3) visitors and members of the public affected by the work.
- No minimum service period. Day one protection.
- Every employer has duties, though the formality of the paperwork scales with the size and risk profile of the business.
- Enforcement sits with the Health and Safety Executive (HSE) (or local authorities for lower-risk premises). The HSE can inspect, issue improvement notices, prohibition notices, and prosecute. After Grenfell and a string of corporate manslaughter cases, sentences for serious safety breaches have climbed sharply.
What to Do If Your UK Workplace Is Unsafe or Your Employer Ignores Health and Safety
- Report hazards in writing — to your line manager, your safety representative, or via the company's reporting system. Email is best because it's timestamped.
- If there's a serious and imminent danger, section 100 of the ERA 1996 gives you the right to leave the workplace without losing pay or facing dismissal — no need to wait for permission.
- Report dangerous conditions to the HSE: 0300 003 1647 or via the online concerns form. Reports can be anonymous.
- If you're hurt at work, make sure it goes in the accident book (employers with 10+ workers are required by law to keep one) and get medical attention. Anything causing 7+ days off work is RIDDOR-reportable by the employer.
- Dismissed or punished for raising a safety concern? That's automatically unfair dismissal under section 100 ERA 1996 with no qualifying period.
What should you NOT do?
- Don't ignore hazards. Section 7 of the 1974 Act puts a legal duty on you, not just the employer, to take reasonable care.
- Don't tamper with safety equipment. Removing guards, disabling interlocks, defeating sensors — these are criminal offences and the HSE prosecutes.
- Don't accept 'we've always done it this way'. Risk assessments have to be reviewed when anything material changes — new equipment, new staff, a near-miss.
