Vehicle utilisation should measure demand, not just mileage

Mileage is easy to report, which makes it a tempting proxy for utilisation. Yet a vehicle may travel little while supporting an important standby function or specialist task. Another may travel extensively because the organisation makes avoidable journeys. A useful fleet review looks at why vehicles are needed.

Define the work being supported

Identify the services that each vehicle or vehicle group enables. Include carrying needs, fitted equipment and response requirements. Ask what would happen if the asset were unavailable. This helps distinguish a real operational dependency from ownership maintained by habit, and prevents a mileage target from becoming the sole basis for removal.

Review the allocation history with the team using the asset. A low mileage vehicle may have a narrow but justified role. It may also sit idle because booking arrangements make it difficult to share. The same statistic can therefore lead to very different decisions, depending on the explanation behind it.

Examine bookings and unavailable time

Look at when demand occurs and when the vehicle cannot be assigned. Maintenance, equipment preparation and missing keys can all affect practical availability. An apparently underused asset may be poorly accessible at the moment another team needs it. Record these barriers so the review can consider process changes as well as fleet size.

Investigate unsuccessful bookings or requests fulfilled through hire and private vehicles. These records can reveal demand that is absent from the vehicle's own mileage history. They also help assess whether removing an asset would simply transfer work elsewhere. The organisation needs a picture of the service demand, not only the activity of vehicles it already owns.

Test sharing carefully

Assess whether teams can share a vehicle without repeated changes to equipment or cargo. A pooling proposal can look efficient on a calendar while creating inconvenient loading work between assignments. Include cleaning, checks and handovers in the discussion. Drivers need a dependable booking process and a vehicle that is ready for the intended task.

Consider whether a smaller or differently specified asset would better suit recurring work. Energy Saving Trust's fleet rationalisation guidance offers context for reviewing vehicle numbers and sizing. Use the review to develop a specific allocation proposal, supported by actual service requirements, rather than treating downsizing as a universal objective.

Evaluate the result after change

When vehicles are pooled, reassigned or removed, monitor unmet demand and the resources used to cover it. Include hire, support time and any effect on the customer service. A lower owned fleet count is not sufficient evidence that the organisation has improved its overall transport arrangement.

Keep utilisation reviews connected to replacement planning and electrification. Removing unnecessary demand can simplify the next investment, while understanding justified standby roles prevents unsuitable deployment. The strongest review explains what each asset enables, when it is needed and whether the work could be supported more effectively. Mileage contributes to that judgement without substituting for it.
