An HSE inspection can happen at any time. There does not need to be an incident or complaint to trigger one — routine, proactive inspections are a core part of the HSE’s enforcement strategy. And when an inspector walks onto your site, they know exactly what to look for.
Understanding what regulators prioritise during a site visit is not about gaming the system. It is about ensuring that your compliance arrangements are genuinely robust, so that when scrutiny comes — whether triggered by an incident, a complaint, or a routine visit — you can demonstrate that you are meeting your legal obligations.
This article explains what HSE inspectors typically focus on during PUWER-related inspections, the evidence they expect to see, and the issues that most commonly result in enforcement action.
The Inspector’s First Impression
Inspectors are trained observers, and they begin assessing your operation the moment they arrive. The general condition of your workplace, the behaviour of your workers, and the visible state of your equipment all contribute to their initial assessment.
Obvious hazards — missing guards, damaged equipment in use, workers operating machinery without PPE, or unsafe practices being carried out in plain sight — will immediately focus the inspection. Conversely, a clean, well-organised workplace with equipment in good visible condition sets a very different tone.
Machine Guarding: The Number One Focus
Guarding of dangerous parts of machinery is almost always the primary focus of a PUWER inspection. Regulation 11 is the most commonly cited regulation in PUWER prosecutions, and inspectors will scrutinise your guarding arrangements closely.
They will check that guards are present, correctly fitted, and effective at preventing access to dangerous parts. They will look for signs that guards have been removed and not replaced, that guards have been modified to allow access, or that interlocking mechanisms have been bypassed or are not functioning correctly.
They will also assess whether the type of guarding is appropriate. Fixed guards should be used wherever possible. Where moveable or interlocked guards are used, the inspector will verify that the interlocking system prevents the machine from operating when the guard is open and, where necessary, that guard locking prevents the guard from opening until the dangerous parts have stopped moving.
Maintenance and Inspection Records
Documentation is crucial. Inspectors will ask to see your maintenance records, inspection logs, and risk assessments. These documents are your evidence that you are managing your equipment proactively. If they do not exist, or if they reveal gaps, inconsistencies, or overdue activities, this is a significant concern.
PUWER Regulation 5 requires that equipment is maintained in an efficient state, in efficient working order, and in good repair. Regulation 6 requires inspections at suitable intervals, carried out by competent persons, with records kept. An inspector will want to see evidence that both requirements are being met systematically.
Controls and Emergency Stops
Inspectors will check that machinery controls are clearly identified and accessible, that start controls are designed to prevent unintentional operation, and that stop controls bring the equipment to a safe stop in an appropriate time.
Emergency stop devices must be easily accessible from all operating positions and must function correctly. Inspectors may test these during their visit. If your emergency stops are inaccessible, obscured, or non-functional, expect enforcement action.
Training Evidence
Regulation 9 requires adequate training for all persons who use work equipment. Inspectors will ask to see training records and may question operators directly about their understanding of safe operating procedures, the risks associated with the equipment they use, and what to do in an emergency.
Training records should demonstrate that each operator has been trained on the specific equipment they use, not just generic health and safety awareness. The records should include the date of training, the content covered, the name of the trainer, and evidence of competence assessment.
Risk Assessments
Inspectors will want to see your PUWER risk assessments and will evaluate whether they are suitable and sufficient. A suitable risk assessment identifies all significant hazards, evaluates the risks, and specifies the control measures in place. It should be specific to the equipment and the way it is used in your workplace — generic, off-the-shelf assessments will not satisfy the HSE.
Risk assessments must also be current. An assessment carried out five years ago and never reviewed is unlikely to reflect the current state of your equipment and operations.
What Triggers Enforcement Action
Inspectors have a range of enforcement tools at their disposal. An improvement notice requires you to remedy a breach within a specified period (minimum 21 days). A prohibition notice stops the use of equipment immediately where there is a risk of serious personal injury. And prosecution can follow where breaches are serious or there has been an injury.
The most common triggers for enforcement are: missing or inadequate guarding, lack of maintenance records, equipment in poor condition, absent or outdated risk assessments, untrained operators, and non-functioning safety devices.
How to Prepare
The best preparation for an HSE inspection is not a last-minute paperwork exercise. It is an ongoing compliance programme that ensures your equipment, documentation, and training are always up to standard.
Safety Management Ltd helps businesses build exactly this kind of programme. We conduct thorough PUWER audits that mirror what an HSE inspector would look for, identifying issues before they become enforcement actions. We help you build documentation systems, training programmes, and inspection schedules that demonstrate genuine compliance — not just paperwork compliance.
