Energy Meter Maintenance Checklist
A maintenance checklist for electrical energy meters and sub-meters covering accuracy verification, CT ratio checks, communication links, and data logging — for energy management and tenant billing.
What is an energy meter maintenance checklist?
A energy meter maintenance checklist is a structured list of the 9 preventive maintenance tasks — covering visual, functional and record-keeping checks — that keep an energy meter running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core energy meter checks
- Inspect CT wiring connections for tightness and correct phasing
- Check the meter display is operational and showing live readings
- Read and record the cumulative kWh value
What is an energy meter?
An energy meter measures electrical energy consumption in kilowatt-hours (kWh). Sub-meters are installed on individual circuits, floors, or tenant areas to provide granular energy data for billing, benchmarking, and efficiency monitoring. Modern meters communicate via pulse outputs, Modbus, or BACnet to the BMS or energy management system. Accurate metering is fundamental to understanding and reducing building energy consumption.
This checklist is one of 6 in our metering maintenance checklists, covering energy, heat, water and gas meters — read integrity, accuracy checks and the data quality behind aM&T reporting.
Typical Energy meter maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Inspect CT wiring connections for tightness and correct phasing
- Verify meter is correctly labelled with the circuit/tenant it serves
Functional Checks
- Check the meter display is operational and showing live readings
- Verify the meter CT ratio matches the installed current transformers
- Compare meter reading against the main fiscal meter (for sub-meters)
- Check communication link to BMS or energy management system
- Check for pulse output or data logging issues
- Review energy data for anomalies or unexpected consumption patterns
Record Keeping
- Read and record the cumulative kWh value

Typical maintenance frequency
Suggested intervals for energy meter maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.
Monthly
- •Record cumulative kWh reading
- •Check display and communication
Annually
- •Verify CT ratio and connections
- •Cross-reference with fiscal meter
- •Review metering data quality
