Which KPIs do you use to steer on workplace inspections?

The most useful workplace inspection KPIs measure three things: whether inspections happen as planned, whether findings get fixed on time, and whether the same problems keep coming back. Combine those leading indicators with lagging ones such as incidents and near misses, and you can see whether your inspections are actually making sites safer.

Counting inspections is easy. Turning inspection data into decisions is harder. This article explains which KPIs to use, how to spot recurring issues, how to compare sites and projects, how to link incidents to earlier findings and how to build a short management report.

Leading vs lagging indicators

HSE's guidance on managing for health and safety (HSG65) distinguishes between active monitoring, which checks that controls are in place before anything goes wrong, and reactive monitoring, which learns from things that have gone wrong. In KPI terms, these are leading and lagging indicators.

	Leading indicators	Lagging indicators
What they measure	Activities that prevent harm	Harm or near harm that already happened
Examples	Inspections completed, actions closed on time, toolbox talks completed	Accidents, lost-time injuries, RIDDOR reports, near misses
Strength	Show problems early, so you can act before an incident	Objective and comparable, and often required by clients
Weakness	Can become box-ticking if you only count activity	Arrive too late to prevent the harm they measure

Workplace inspections are a leading indicator by nature. The trick is to pick KPIs that measure quality, not just quantity.

The core workplace inspection KPIs

Start with a small set you can actually maintain.

KPI	How to calculate	What it tells you
Inspection completion rate	Inspections completed ÷ inspections planned	Whether your inspection plan is being followed
Actions closed on time	Actions closed by deadline ÷ actions due	Whether findings actually get fixed
Overdue actions	Number of open actions past deadline, by priority	Where follow-up is stalling
Average time to close	Average days from finding to verified close-out	How quickly risks are removed
Findings per inspection, by category	Findings ÷ inspections, split by topic	Which hazards dominate
Repeat findings	Findings on the same topic and location as a previous inspection	Whether fixes last
High-severity findings	Number of stop-work or high-priority findings	How serious the risks are
Positive observations	Number of good-practice findings	Whether inspections also recognise what works

Be careful with "findings per inspection". More findings is not automatically bad: it can mean better inspectors. Fewer findings is not automatically good: it can mean inspections have become superficial. Always read it together with severity and repeat findings.

Setting realistic targets

A KPI without a target is just a number. Set targets that push improvement without encouraging people to game the figures.

• Completion rate: aim high, for example 95% or more of planned inspections, and ask why when a site misses it.
• Actions closed on time: set separate targets per priority. Immediate and high-priority actions should be close to 100%.
• Repeat findings: aim for a downward trend rather than a fixed number.
• Avoid targets on the number of findings. A target of "fewer findings" rewards inspectors who stop looking.

Review the targets once a year. When a site consistently hits them, raise the bar or shift the focus to a different KPI.

Identifying recurring issues

Recurring issues are the most valuable signal in your inspection data. They show where a control does not work, where knowledge is missing or where planning creates pressure.

• Use fixed categories. Only consistent categories (work at height, housekeeping, PPE, electrics and so on) let you count repeats.
• Look per location and per contractor. The same finding in the same place points to layout or equipment; the same finding with the same contractor points to knowledge or supervision.
• Set a threshold. For example: a topic that appears in three consecutive inspections triggers a root-cause review.
• Ask why five times. A missing guard rail may come back because the scaffold design forces workers to remove it for deliveries.

Once you find the cause, choose the fix accordingly: a design or equipment change for physical causes, a targeted toolbox talk for knowledge gaps, and supervision or planning changes for behaviour under pressure.

Comparing results across locations and projects

Comparing sites only works if they inspect in the same way. Use one core checklist, one severity scale and one system for all records. Then compare:

• inspection completion rate per site;
• actions closed on time per site and per contractor;
• high-severity findings per inspection;
• the top three categories per site.

Normalise where needed. A large site with ten contractors will produce more findings than a small one; compare findings per inspection rather than totals. Use comparisons to learn, not to blame. The site with the most findings may simply have the sharpest inspector.

Linking incidents to earlier findings

When an incident or near miss happens, check the inspection history for that location and topic.

• Was the hazard ever found during an inspection?
• If so, was an action assigned, and was it closed and verified?
• If not, was the area inspected, and does the checklist cover this hazard?

The answers show whether the gap was in finding, fixing or verifying. Each points to a different improvement. This is also what an HSE inspector or your insurer will ask after a serious incident, and whether it needs reporting under RIDDOR 2013 does not change the question.

Using inspection data to prevent accidents

Data only prevents accidents when it changes what happens on site. Turn your KPIs into action:

1. Review the main KPIs every month with site management.
2. Pick the one or two categories that recur most and agree a specific measure for each.
3. Send a targeted toolbox talk on those topics to the teams concerned.
4. Focus the next round of inspections on those topics.
5. Check after a month whether the repeat findings have dropped.

Management report template

A good management report fits on one page. Use this structure every month:

Section	Content
Headlines	Three sentences: what improved, what got worse, what needs a decision
Activity	Inspections planned vs completed, per site
Follow-up	Actions closed on time, overdue actions by priority, average time to close
Risk picture	High-severity findings, top three categories, repeat findings
Incidents	Accidents, near misses, RIDDOR reports, and whether they were preceded by inspection findings
Actions	What was done about last month's priorities, and what is proposed for next month

Add trend lines over at least six months. One month on its own says little; a trend tells the story.

Measuring whether inspections lead to a safer workplace

Ultimately you want to know whether inspections make a difference. Look at the combination:

• High completion rate and actions closed on time.
• Repeat findings falling over time.
• High-severity findings falling.
• Near-miss reporting stable or rising (people still report) while injuries fall.

If inspections are done and actions are closed but repeat findings stay flat, your fixes are not reaching the cause. Revisit the corrective action process.

Frequently asked questions

What are the best KPIs for workplace inspections?

Inspection completion rate, actions closed on time, overdue actions, average time to close, repeat findings and high-severity findings. Together they show whether inspections happen, whether findings get fixed and whether the fixes last.

Are workplace inspections a leading or lagging indicator?

Leading. They measure activity aimed at preventing harm. Combine them with lagging indicators such as injuries and near misses to get the full picture.

How do I compare inspection results across sites?

Make sure all sites use the same core checklist, severity scale and categories, record them in one system, and compare ratios such as findings per inspection rather than totals.

How often should I report on inspection KPIs?

Monthly for site and operational management, quarterly for the board. Use trend lines over at least six months to separate real change from noise.

What does it mean if inspections find fewer and fewer problems?

It can mean the site is genuinely safer, or that inspections have become superficial. Check severity, repeat findings and incident data, and occasionally let a different inspector walk the same site.
