KEY POINTS
- Compare maintenance proposals against the same asset list and tasks.
- Define planned outages, reporting and corrective work separately.
- Keep preventive maintenance distinct from statutory inspection requirements.
An electrical preventive maintenance proposal should identify the equipment covered, the work to be carried out, the access needed and the records delivered. A visit frequency or contract price alone does not tell you whether two proposals cover the same work.
Start with the equipment register
Give each board or asset a unique identifier. Record its location, function, available manufacturer information and known defects. Mark equipment serving critical operations so the maintenance team can discuss its access constraints with the operations team.
Use the same register when comparing contractors. If one proposal covers only the main distribution boards and another includes downstream equipment, reconcile the difference before comparing totals.
Put the tasks and exclusions in writing
| Contract item | What to clarify |
|---|---|
| Covered assets | Named equipment and quantities, with additions handled through agreed changes |
| Planned tasks | Inspection, cleaning, measurements or tests assigned to each asset |
| Access and outages | Permits, isolation responsibilities and operational restrictions |
| Findings | Asset reference, observation, supporting evidence and agreed urgency |
| Corrective work | What is included, what needs a quotation and who authorises it |
| Follow-up | Action owner, target date and evidence required to close the finding |
The inspection frequency and method should be agreed by the responsible team using equipment guidance, condition and operating requirements. Do not apply one generic interval or test list to every asset.
Define what thermal scanning contributes
Thermal images can help identify temperature patterns for investigation. They need context. Fluke explains how reflections and surface properties affect hot-spot interpretation. A report should state what was observed and any limitations, rather than treat one image as proof of a fault.
Our thermal scanning guide gives a more detailed reporting checklist. Inspection access must be planned by competent personnel under the site’s electrical safety procedures.
Keep maintenance and compliance documents separate
A maintenance report is not automatically the statutory inspection record required for a particular facility. Ask the responsible engineer which inspection obligations apply and whether those inspections are included in the appointment. Our factory inspection document guide helps organise that discussion.
Use project evidence to check the proposed scope
ETES’s published AWS BKK project includes MDB preventive maintenance, cleaning and thermal scanning. Ask how the proposed tasks for your site compare with that documented scope, and what additional work your equipment needs.
ETES offers M&E maintenance contracts for agreed terms of one, two, three or five years. Prepare the asset list, previous reports, operating hours and available outage windows before requesting a proposal. Confirm included tasks and additional-work rates in the contract.
Questions for the maintenance review
Is repair included when a defect is found?
Only if the agreed scope includes that work. Set a reporting and quotation process for repairs, replacement parts and specialist investigations.
What makes a report useful at the next visit?
Consistent asset identifiers, comparable observations, clearly stated inspection conditions and a record of what happened to earlier findings.
