Accredited accident and incident investigation training for managers, supervisors, health and safety professionals and appointed investigators. Courses cover root cause analysis, near miss reporting, evidence gathering, RIDDOR reporting requirements and practical investigation methods to prevent recurrence of workplace incidents.

Failure to investigate accidents and near misses effectively — or to report RIDDOR-reportable incidents to the HSE — can result in unlimited fines, prosecution and preventable repeat injuries. Training helps organisations build robust investigation procedures that meet legal requirements and improve workplace safety performance.

Why accident investigation training matters

Identify root causes

Investigation training helps learners look beyond immediate causes to identify underlying management, system and behavioural factors that contributed to an incident.

Prevent recurrence

Effective investigations produce actionable recommendations that reduce the likelihood of repeat accidents and near misses across the organisation.

Meet RIDDOR obligations

Training ensures those responsible understand what must be reported to the HSE, within what timeframe, and the consequences of failing to report.

Build a reporting culture

Near miss training encourages frontline workers and managers to report incidents without fear, creating the data organisations need to manage risk proactively.

Demonstrate due diligence

Documented investigation training provides evidence of competence during HSE inspections, insurance audits and civil litigation proceedings.

Reduce costs

Workplace accidents cost UK employers billions each year in lost productivity, compensation claims and enforcement action. Effective investigation and prevention training reduces this exposure significantly.


Frequently asked questions

An accident involves an unplanned event that results in injury, ill health or damage. An incident is a broader term that includes near misses — unplanned events that did not result in harm but had the potential to do so. Both require investigation. Near miss investigation is particularly valuable because it allows organisations to identify and control risks before a serious injury occurs.
Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR), employers must report deaths, specified injuries (such as fractures, amputations and crush injuries), over-seven-day incapacitation injuries, occupational diseases and dangerous occurrences. Reports must be made to the HSE, usually within 10 days. Failure to report is a criminal offence. See our RIDDOR training course for full guidance.
Investigation should be carried out by someone with appropriate training, authority and independence from the area where the incident occurred. For minor incidents, a line manager or supervisor may lead. For serious accidents, a trained lead investigator or health and safety professional should be involved. Our Lead Accident Investigator course is designed specifically for those taking on this responsibility.
There is no specific legal requirement to hold a qualification in accident investigation. However, the Health and Safety at Work etc. Act 1974 requires employers to provide adequate training to employees, and the Management of Health and Safety at Work Regulations 1999 require employers to have procedures for responding to serious and imminent dangers. Training equips investigators with the skills to fulfil these duties competently.
Root cause analysis (RCA) is an investigation method used to identify the underlying systemic factors that contributed to an accident, rather than focusing solely on immediate causes. Common RCA techniques include the 5 Whys, fishbone (Ishikawa) diagrams and fault tree analysis. Identifying root causes allows organisations to implement controls that prevent recurrence rather than simply treating symptoms.
Yes. Many accident and incident investigation courses can be delivered on-site at your premises by a qualified instructor. On-site delivery allows training to be contextualised to your specific industry, workplace and incident history, and is cost-effective for groups of four or more.
