Fleet & maintenance
Building a preventive maintenance plan for a courier fleet
How to combine manufacturer servicing, safety checks, defects and operating conditions in one forward plan.
In brief
What an operator should know.
A useful planner shows what is due, why it is due, who owns it and whether the vehicle is available. It changes when mileage, age or operating conditions change.
Put every maintenance event in one view
Include servicing, applicable safety inspections, MOT or annual test, tyres, recalls, tail-lifts and specialist systems. Book far enough ahead that operational work can be moved without last-minute cancellation.
- List owned, leased and hired assets
- Include first-use evidence
- Show booked, due, complete and overdue status
Set intervals from risk and use
Use manufacturer guidance and licence undertakings as a starting point, then consider age, mileage, stop-start work, heavy loads, rough sites, seasonal peaks and defect history. Arduous conditions may justify additional checks.
- Document the reason for each interval
- Use competent review
- Reassess after operating change
Monitor whether the plan works
Compare planned dates with completion, defects between events, roadside findings, test outcomes and breakdowns. A planner can be punctual but ineffective if vehicles repeatedly fail between maintenance events.
- Review fleet and provider changes
- Keep records accessible
- Investigate missed dates and repeat defects
Practical action plan
What to do next.

Add manufacturer, legal, licence and equipment requirements.
- 03Book forward
Reserve workshop capacity and operational cover.
- 04Review evidence
Use defects, failures and utilisation to test intervals.

Direct answers
Common questions.
Is a service the same as a safety inspection?
No. They have different purposes and scope. Identify which events each vehicle requires.
Should older vans be inspected more often?
Possibly. Consider age with mileage, use, condition and defect history.
Do hired vehicles belong on the planner?
Yes. The operator still needs evidence that a hired vehicle is safe and maintained.
