6 Essential Fleet Maintenance KPIs Every Construction Manager Should Be Tracking

Most managers are already tracking some key metrics, maybe it’s service history, repair costs, or vehicle availability. The challenge is knowing what’s actually useful, what’s missing, and whether that data is helping to prevent problems. When dealing with fleets daily, it’s easy to fall into habits and overlook the early signs of issues developing.

This is where the right key performance indicators (KPIs)for Fleet maintenance can offer real value. When chosen and monitored effectively, they give construction fleets a way to measure performance, identify patterns, and make informed decisions based on evidence.

Why Fleet Maintenance KPIs Matter

For construction fleets, making smarter decisions and reducing downtime matters. Vehicles are often exposed to harsh conditions, irregular usage patterns, and long hours on site. Tracking the right maintenance KPIs gives managers a way to get ahead of problems, rather than just reacting when something goes wrong.

When used well, maintenance KPIs can help reduce unplanned downtime, extend vehicle life, and create a more consistent servicing routine. That means improved reliability and compliance of vehicles, fewer last-minute repairs, better visibility of costs, smarter resource planning and stronger compliance with safety standards.

6 Essential Fleet Maintenance KPIs to Track

Scheduled vs. Unscheduled Maintenance

How much of your maintenance is proactive rather than reactive? A high ratio of unscheduled work leads to higher costs and greater disruption. It can also indicate vehicles are being driven or used in a risky/careless manner.

Monitoring repair costs is crucial for managing budgets, and logging maintenance events for each vehicle, helps highlight anomalies where specific vehicles consistently cost more to maintain. Fleetclear Connect’s telematics and driver behaviour data can shed light on when maintenance costs are linked to poor driving practices such as harsh braking, rapid acceleration, or cornering. This helps managers decide whether repair strategies are delivering value, or whether investment in driver training and preventative measures is required.

Vehicle Utilisation and Engine Run Time

Vehicles are company assets and need to be in use make money. Downtime when a vehicle is off the road for any reason, whether maintenance, repairs, or servicing, costs an organisation. On the flip side, telematics data helps fleet and site managers spot poor utilisation of vehicles on and off site to build up a more accurate picture of vehicle availability, utilisation and where assets can be re-deployed.

Vehicle utilisation can be monitored by tracking of journeys, or more simply by monitoring the engine run time. On-site machinery, such as forklifts, telehandlers and cherry pickers are often overlooked elements of a company fleet, but for these vehicles, which rarely if ever use public roads, engine run time is the key metric to track usage.

True Idling

Idle time is another overlooked KPI which can significantly increase fuel use and vehicle wear. Fleetclear Connect uses telematics data to capture when, where, and how long vehicles are idling for, turning this into actionable insights that reduce wasted fuel and unnecessary wear .Crucially, unlike many other systems, Fleetclear can distinguish between a specialist vehicle using PTO whilst idling, vs an engine left running unnecessarily. Termed ‘True Idling’, this gives managers clearer visibility into operational efficiency.

Fuel efficiency trends post-maintenance

After a major service or repair, it’s important to measure whether fuel performance has improved. Tracking this KPI shows whether maintenance is genuinely improving efficiency or if underlying issues remain. Vehicle operational data, displayed in Fleetclear Connect, captures how much fuel is being used, giving managers the baseline data they need to monitor trends and make informed decisions.

Recurring faults and component failures

When the same issue appears repeatedly, whether on a single vehicle or across the fleet, it’s often a sign of a deeper problem, such as a failing component, ineffective repairs, or a wider operational issue. Tracking the nature of specific issues helps managers carry out root cause analysis, prioritise preventative action, and stop small, repeat issues from escalating into costly breakdowns.

How to Capture and Use Your Fleet Data

For construction fleets, the most effective maintenance strategies rely on consistent, reliable fleet data. Telematics and monitoring systems now make it simple to automate that process, tracking everything from mileage and fuel use to faults and servicing dates.

By linking vehicle inspections, maintenance records, service scheduling and live telematics insights, managers get a single platform to measure every KPI mentioned above. Once the data is standardised and centralised, it’s easier to review monthly, act on early warnings, and prioritise resources where they matter most.
