Construction health and safety KPIs are measurable indicators that show whether an organisation is effectively controlling health and safety risks. The most useful approach combines lagging indicators, such as injuries and incidents, with leading indicators that measure inspections, risk controls, corrective actions, training and worker engagement.
For UK construction companies, measuring safety performance remains critical. Provisional HSE figures show that 25 construction workers suffered fatal injuries in 2025/26, the highest number of worker fatalities of any main industry sector that year. But accident statistics only show what has already happened.
Good construction health and safety KPIs should also show whether critical controls are working, where risks are rising and where action is needed. This guide explains the leading and lagging indicators UK construction companies can use to monitor safety performance.
What are health and safety KPIs?
A health and safety key performance indicator (KPI) is a measurable value used to track how effectively an organisation is managing health and safety.
Examples include:
- Number of reportable incidents
- Injury frequency rates
- Near-miss reporting
- Percentage of planned inspections completed
- Corrective actions closed on time
- Permit-to-work compliance
- Training and competency compliance
- Health surveillance completion
- Worker safety observations
- High-risk control verification
The objective is not to collect as many construction safety metrics as possible. It is to choose indicators that show whether risks are being controlled and where action is needed.
HSE’s Managing for health and safety (HSG65) recommends monitoring health and safety in much the same way as other areas of business performance. It distinguishes between active monitoring, which looks at whether preventive arrangements are operating as intended, and reactive monitoring, which examines incidents, ill-health and other evidence of poor performance. This broadly reflects the difference between leading and lagging safety indicators.
Why health and safety KPIs matter in construction
Construction sites change continuously. Contractors, work activities, equipment and access arrangements can all change as a project progresses.
Health and safety KPIs help managers understand whether these changing risks are under control. They can highlight negative trends, verify critical controls, compare projects and focus attention where it is needed most.
The aim is not reporting for its own sake. KPIs should support better safety decisions.
Leading vs lagging health and safety indicators
A balanced set of health and safety KPIs should include both leading and lagging indicators.
Lagging indicators measure events or outcomes that have already happened. These measures help organisations understand what has gone wrong and learn from past events. Their limitation is that they only show problems after they have occurred. Low incident numbers can also be misleading. They may reflect strong safety performance, but they can also result from low exposure, under-reporting or chance.
Leading indicators measure the activities and controls intended to prevent incidents. HSE describes this type of monitoring as active and preventive. For construction organisations, leading indicators can provide earlier warning that safety performance is deteriorating. If inspections are missed, corrective actions remain overdue or permit compliance falls, management can act before an accident occurs.

12 construction health and safety KPIs worth tracking
There is no universal list that will work for every contractor or project. The right KPIs should reflect the organisation’s main risks, operating model and safety objectives. These 12 indicators provide a practical starting point.
Fatalities and serious injuries
Track serious outcomes by incident type, activity, project, contractor and root cause to identify recurring patterns and control failures.
Track: Fatalities, serious injuries, critical control failures
RIDDOR-reportable incidents
Monitor incidents that meet RIDDOR requirements, while recognising that these events alone do not provide a complete picture of current safety performance.
Track: Reportable injuries, diseases and dangerous occurrences
Injury frequency rate
Relate the number of injuries to workforce exposure so you can compare performance across projects of different sizes.
Formula: Qualifying injuries × normalisation factor / hours worked
Near-miss reporting rate
Use near-miss data to identify hazards and weak controls before they result in injury.
Track: Reports, recurring hazards and follow-up actions
Safety inspection completion rate
Measure whether planned inspections are being completed and whether critical risks are being checked.
Formula: Inspections completed / inspections planned × 100
Corrective action closure rate
Track whether identified safety issues are resolved on time, with greater attention given to high-risk actions.
Formula: Actions closed by due date / actions due × 100
Permit-to-work compliance
Check whether high-risk activities are covered by the right permits, approvals and controls before work starts.
Track: Approved permits, deviations and correct closure
Risk assessment and RAMS compliance
Verify that relevant work has approved RAMS and that workers have been briefed on the required controls.
Track: Approved RAMS, briefings and deviations
Training and competency compliance
Confirm that workers have the required training, certifications and competencies for the tasks they perform.
Track: Valid training, inductions and expired qualifications
Safety observations and hazard reporting
Monitor the hazards and unsafe conditions identified by workers and supervisors, together with the actions that follow.
Track: Observations, recurring issues and closure time
Occupational health indicators
Track health risks such as dust, noise, vibration and other exposures alongside traditional safety measures.
Track: Health surveillance, exposure monitoring and work-related absence
Worker and leadership engagement
Measure how actively workers, supervisors and leaders participate in safety activities and raise concerns.
Track: Safety visits, toolbox participation, suggestions and response times
Construction health and safety KPI examples
A balanced construction dashboard might look something like this:
| KPI | Type | What it can tell you |
|---|---|---|
| Fatalities and serious injuries | Lagging | Severity of past incidents |
| RIDDOR incidents | Lagging | Reportable safety outcomes |
| Injury frequency rate | Lagging | Injury performance adjusted for exposure |
| Near-miss reporting | Reactive / engagement | Hazards and reporting culture |
| Inspection completion | Leading | Whether planned monitoring is taking place |
| High-risk control checks | Leading | Whether critical controls are operating |
| Corrective actions closed on time | Leading | How effectively identified risks are addressed |
| Permit compliance | Leading | Control of high-risk work |
| Training and competency compliance | Leading | Whether workers meet competency requirements |
| Safety observations | Leading / engagement | Workforce participation and emerging hazards |
| Health surveillance compliance | Leading | Management of occupational health risks |
| Occupational illness and absence | Lagging | Evidence of work-related health impacts |
The objective is balance. A dashboard dominated by injury statistics looks backwards, while activity measures alone do not prove that risks are controlled. The strongest view combines both.
How to choose the right construction safety KPIs
Start with the risks, not the dashboard.
1. Identify your critical risks
Consider the activities capable of causing the most serious harm. Depending on the project, these could include:
- Working at height
- Lifting operations
- Mobile plant
- Temporary works
- Excavation
- Electrical work
- Confined spaces
- Hot work
- Silica dust
- Asbestos
- Noise
- Vibration
2. Identify the critical controls
Ask what needs to work correctly to prevent the unwanted event. For work at height, for example, this could include edge protection, suitable access equipment, inspections and worker competency.
3. Define how you will verify the controls
This becomes the basis for useful leading KPIs. Instead of measuring only the number of inspections completed, measure whether critical controls were checked and passed. For example:
Percentage of planned work-at-height control inspections completed and passed
4. Pair leading and lagging indicators
Where possible, combine indicators. For example:
- Leading: Percentage of required lifting plans approved before work.
- Lagging: Number of lifting incidents and near misses.
Or:
- Leading: Percentage of corrective actions from dust inspections closed on time.
- Lagging: Exposure-monitoring failures or occupational health cases.
This gives managers a clearer view of whether controls are working and whether they are producing the desired result.
How many construction safety KPIs should you track?
Senior managers do not need dozens of indicators on one dashboard. Use a small set of company-wide KPIs, supported by more detailed project and operational measures. A practical structure could include:
- A small group of company-wide KPIs
- Project-level indicators
- High-risk activity indicators
- Contractor performance metrics
- Detailed operational measures
This gives leaders consistency without forcing every project to measure exactly the same risks.
Avoid these common KPI mistakes
Measuring activity instead of effectiveness: Completing 500 toolbox talks does not prove that workers understand critical risks. Look beyond volume to outcomes and quality.
Treating every increase as negative. More near-miss reports or safety observations may indicate better engagement and transparency. Understand what is driving the trend before drawing conclusions.
Comparing projects without normalising data. A project with 2,000 workers cannot be compared directly with one employing 200. Use hours worked, workforce numbers or another suitable exposure measure where appropriate.
Focusing only on injuries. Low injury numbers do not prove that high-risk controls are effective. Leading indicators help identify weaknesses before someone gets hurt.
Ignoring occupational health. Some health impacts develop over months or years. Relying on diagnosed ill-health cases alone can be misleading because these may reflect exposure from years earlier. Leading health indicators such as exposure monitoring and health surveillance are therefore particularly important.
Tracking KPIs without taking action. A dashboard is not a safety programme. Every KPI should have:
- A clear definition
- An owner
- A target or threshold
- A reporting frequency
- An escalation process
- Agreed actions when performance deteriorates
If nobody knows what happens when an indicator turns red, the metric has limited value.
From monthly reporting to real-time safety insights
One of the biggest challenges with traditional safety reporting is the delay between what happens in the field and what management sees. Site teams complete paper inspections, spreadsheets are updated, data is consolidated and monthly reports are prepared. By the time a trend becomes visible, several weeks may have passed. Digital safety management changes this process. When inspections, permits, observations, training, incidents and corrective actions are captured digitally, organisations can analyse the information as work happens.
Safety teams can monitor:
- Overdue actions
- Inspection compliance
- Recurring hazards
- Contractor performance
- High-risk activities
- Incident trends
- Training gaps
- Permit status
- Occupational health controls
Leading construction safety platforms increasingly emphasise this connection between field activity, leading indicators and management reporting rather than relying only on historical incident statistics. This makes safety data useful for operational decisions, not just monthly reporting.
How can construction safety software improve KPI reporting?
Construction organisations often have the data they need, but it is fragmented across paper forms, spreadsheets, emails and separate systems. This makes consistent safety performance measurement difficult.
A digital construction safety platform can help organisations:
- Standardise safety processes across projects
- Capture structured data directly from the field
- Automate KPI calculations
- Track leading and lagging indicators
- Analyse performance by project or contractor
- Monitor actions in real time
- Identify recurring hazards
- Reduce manual reporting
- Create consistent dashboards
- Maintain auditable safety records
More importantly, the underlying data can be connected. An incident can be linked to a hazard category. The hazard can be compared with previous observations. Inspection findings can be linked to corrective actions. Contractor performance can be analysed across several projects. This creates a much richer view of risk than a standalone monthly safety spreadsheet.
Using Novade to monitor construction health and safety performance
Novade construction health and safety software helps construction companies digitise safety processes and turn field activity into trusted operational data.
Teams can manage processes including:
- Safety inspections
- Observations
- Incidents
- Corrective actions
- Toolbox talks
- Training
- Permits to work
- Risk assessments
- Workforce compliance
- Safety forms and checklists
Site teams capture information directly from mobile devices, while managers can use dashboards and analytics to monitor performance across projects. By connecting safety activities in one system, organisations can move beyond reporting isolated incident totals and develop a clearer picture of where risks are emerging, whether controls are being applied and where management attention is required.
