A COSHH inspection from the Health and Safety Executive (HSE) is not something any responsible employer should take lightly. The Control of Substances Hazardous to Health Regulations 2002 place a legal duty on every employer to protect workers from exposure to hazardous substances — and the consequences of failing to comply can be severe. From financial penalties to criminal prosecution, the enforcement landscape has hardened significantly in recent years.
What Triggers a COSHH Inspection?
HSE inspectors visit workplaces for a variety of reasons: routine sector-based inspection programmes, complaints from employees or members of the public, follow-up visits after a reported accident or near miss, or as part of targeted campaigns in high-risk industries such as construction, chemicals manufacturing, or food processing. You are unlikely to receive advance warning of a reactive inspection, which is precisely why your compliance posture must be maintained at all times.
The Enforcement Ladder
The HSE operates a clear enforcement policy. When an inspector identifies a breach of COSHH regulations, they will take action proportionate to the risk presented. The typical progression looks like this:
| Enforcement Level | What It Means | Typical Trigger |
|---|---|---|
| Verbal/Written Advice | Informal notice to improve | Minor, low-risk non-compliance |
| Improvement Notice | Legal duty to rectify within a set timeframe | Identifiable breach with moderate risk |
| Prohibition Notice | Immediate cessation of activity | Risk of serious personal injury |
| Fee for Intervention (FFI) | Hourly cost recovery charge (currently £163/hour) | Any material breach identified |
| Prosecution | Criminal proceedings in Crown or Magistrates Court | Serious breaches, repeat offending, fatalities |
Financial Penalties: What Are the Real Costs?
Since the introduction of the Sentencing Council guidelines in 2016, fines for health and safety offences have escalated dramatically. Magistrates Courts can impose unlimited fines, while the Crown Court has handed down multi-million pound penalties to large organisations. For smaller businesses, fines are scaled against turnover — a firm with revenues of £2 million could realistically face a fine of £100,000 or more for a Category A (high culpability, serious harm) offence.
Beyond the direct fine, businesses face Fee for Intervention charges that accumulate from the moment a material breach is identified. Add in legal fees, remediation costs, increased insurance premiums, reputational damage, and operational downtime, and a single COSHH failure can easily cost a business six figures.
Criminal Prosecution and Custodial Sentences
Prosecution under the Health and Safety at Work etc. Act 1974 can result in unlimited fines for organisations and, for individuals (directors, managers, employees), up to two years' imprisonment. HSE does not hesitate to pursue individuals in cases involving gross negligence or deliberate disregard for worker safety. The Corporate Manslaughter and Corporate Homicide Act 2007 adds a further layer of exposure where a fatality is linked to a management failure.
What Do Inspectors Look For?
A COSHH inspection will typically assess whether you have conducted suitable and sufficient COSHH assessments, implemented appropriate control measures, provided adequate training and supervision, maintained records of assessments and health surveillance, and ensured emergency arrangements — including spill response — are fit for purpose.
Inadequate spill control is a common finding. If your site stores, handles, or disposes of hazardous chemicals without appropriate spill kits and containment measures, you are exposed. Explore our range of COSHH-compliant spill kits and secondary containment solutions to close any gaps before an inspector does it for you.
How to Prepare for a COSHH Inspection
The most effective preparation is simply to maintain compliance continuously. Review your COSHH assessments annually or after any significant change in substances or processes. Conduct regular internal audits of your chemical storage, handling procedures, and emergency response arrangements. Ensure your spill kits are stocked, accessible, in-date, and that staff know how to use them. Keep records accessible and up to date.
Reactive preparation — scrambling to fix problems when an inspector is at the gate — is both futile and, under the Fee for Intervention scheme, expensive.
Key Takeaway
Failing a COSHH inspection is not simply an administrative inconvenience. It carries real financial, legal, and reputational risk. The best defence is a proactive compliance programme backed by the right equipment and documentation. Do not wait for the HSE to tell you where your gaps are.
