When a serious workplace accident or fatality occurs, the consequences can be devastating, not only for the individuals involved but also for the business and its directors. In the UK, incidents of this nature typically trigger an investigation by the Health and Safety Executive (HSE), a powerful regulatory body with wide-ranging enforcement powers.
For directors and senior managers, this can mean more than just reputational damage. It may involve criminal prosecution, large financial penalties, or even custodial sentences. That’s why it is crucial for businesses to understand what a health and safety investigation involves and how to protect their organisation and its leadership from the outset.
In this blog, we’ll explore the steps to take following a workplace incident, how HSE investigations unfold, and why seeking immediate legal advice from health and safety solicitors is essential for safeguarding your business.
What Triggers a Health and Safety Investigation?
A health and safety investigation by the HSE is typically launched following:
- A fatality or life-threatening injury at work
- Serious injuries requiring hospitalisation
- Occupational diseases (e.g. asbestos exposure)
- Dangerous occurrences or “near misses”
- Complaints from employees or third parties
- Concerns raised by other regulatory bodies or insurers
Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), employers are legally required to report certain types of incidents to the HSE. Once notified, the HSE will determine whether an investigation is warranted based on the severity and circumstances of the event.
What Powers Does the HSE Have?
The Health and Safety Executive holds considerable authority. Its inspectors can:
- Enter your premises without notice
- Examine and take copies of documents
- Conduct interviews under caution
- Seize equipment or materials
- Issue enforcement notices (Improvement or Prohibition Notices)
- Recommend prosecution in the Crown Court or Magistrates’ Court
It’s vital to understand that an HSE investigation is not simply an internal review; it is a formal legal process with potentially serious outcomes.
Step-by-Step: What to Do If the HSE Launches an Investigation
1. Do Not Panic, But Act Quickly
The moments following an incident are critical. While it is natural to feel overwhelmed, avoid knee-jerk reactions. Gather the facts, secure the scene (unless doing so would create further danger), and inform your legal representative immediately.
2. Avoid Making Admissions
It’s important to cooperate with investigators, but do not admit liability, speculate on the cause, or volunteer unnecessary information. Even well-meaning comments can be misinterpreted or used against you.
3. Preserve Evidence
Keep records of risk assessments, training logs, maintenance schedules, CCTV footage, and any documentation related to health and safety protocols. This evidence can be vital in demonstrating compliance or building a legal defence.
4. Notify Your Insurers
Your liability or professional indemnity insurance may provide coverage for legal costs and claims arising from HSE investigations. Notify your insurer as soon as possible and provide them with regular updates.
5. Seek Immediate Legal Advice
Legal representation from a solicitor specialising in health and safety law is essential. They can advise on your rights, help prepare for interviews under caution (PACE interviews), and guide you through each stage of the investigation.
Interviews Under Caution (PACE)
If the HSE believes that an offence may have been committed under the Health and Safety at Work etc. Act 1974, directors or staff may be asked to attend an interview under the Police and Criminal Evidence Act (PACE). These interviews are formal, recorded sessions where anything said can be used as evidence in court.
You have the right to legal representation in these interviews, and you should never attend one without it.
Common Outcomes of Health and Safety Investigations
After gathering evidence, the HSE may decide to:
- Take No Further Action – if compliance is demonstrated
- Issue an Improvement Notice – requiring action within a set timeframe
- Issue a Prohibition Notice – stopping unsafe practices immediately
- Prosecute – in severe cases, especially where there is evidence of negligence, systemic failure, or repeat offences
Recent sentencing guidelines have significantly increased the penalties for health and safety offences. Fines can run into the millions, particularly for large businesses, and company directors can face disqualification or imprisonment.
Key Legal Duties for Employers and Directors
Under the Health and Safety at Work Act, both companies and individuals can be held accountable for failings that result in harm. These include:
- Corporate Liability – where the organisation as a whole fails in its duties
- Director or Manager Liability – where senior individuals have consented to or been complicit in the failings
- Gross Negligence Manslaughter – in cases of fatalities linked to gross breaches of duty
Directors and managers have a duty to:
- Ensure health and safety procedures are in place
- Provide appropriate training and supervision
- Carry out regular risk assessments
- React promptly to safety concerns or complaints
Being proactive in these areas is not only a legal obligation, it also provides a strong defence if things go wrong.
