Why there is no universal servicing interval
There is no single legal requirement specifying a fixed servicing interval for every charger. Usage, environment, manufacturer guidance and previous inspection findings all influence maintenance frequency.
Usage matters more than age
A lightly used office charger and a busy retail charger of the same age may require very different maintenance regimes.
What planned servicing should include
Visual inspections, electrical safety checks, cable and connector inspections, functional testing, firmware reviews and software health checks should all form part of a structured maintenance visit.
Planned versus reactive maintenance
Waiting until a charger fails usually increases costs and downtime. Planned maintenance helps identify deterioration before failure occurs.
Signs additional servicing may be required
Frequent faults, communication failures, physical damage, user complaints and recurring error messages all suggest earlier intervention may be appropriate.
