Gas Meter (Mains & Sub-Meter) Maintenance Checklist
Keep gas data accurate and the installation safe — reading reconciliation, pulse-output verification, ventilation and leak checks, and correction-factor confirmation.
Also available as editable Excel and Word — with asset, sign-off and findings columns.
What is a gas meter maintenance checklist?
A gas meter (mains & sub-meter) maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional, safety and record-keeping checks — that keep a gas meter (mains & sub-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 gas meter checks
- Check the meter housing is ventilated and not enclosed or obstructed
- Take a manual reading and reconcile against the BMS/aMR logged value
- Inspect for signs of gas leakage (smell, hissing) and escalate immediately if found
- Apply the correct volume-correction/calorific factor for energy reporting
What is a gas meter (mains & sub-meter)?
A gas meter records the volume of natural gas consumed, at the incoming supply for billing or as a sub-meter for plant-level monitoring and tenant recharge. Diaphragm and rotary/turbine meters are common, often with a pulse output feeding the BMS or aMR system for energy reporting. Gas metering carries a safety dimension that water and electricity metering do not: the meter installation, ventilation, and any work near it fall under gas safety rules and must involve Gas Safe registered engineers for intrusive work. FM maintenance focuses on non-intrusive checks — reading accuracy, pulse outputs, ventilation, signs of leakage — and escalating anything intrusive to a competent engineer.
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 Gas 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
- Check the meter housing is ventilated and not enclosed or obstructed
- Inspect the meter, pipework, and connections for corrosion and damage
- Verify meter identification matches the metering schedule and drawings
Functional Checks
- Take a manual reading and reconcile against the BMS/aMR logged value
- Confirm the pulse/comms output increments and matches the register
Safety Checks
- Inspect for signs of gas leakage (smell, hissing) and escalate immediately if found
- Confirm the emergency control valve is accessible and clearly identified
Record Keeping
- Apply the correct volume-correction/calorific factor for energy reporting
- Review consumption trends for unexplained changes
- Record readings, pulse checks, and observations in the metering log

Typical maintenance frequency
Suggested intervals for gas meter (mains & sub-meter) maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.
Monthly
- •Reconcile manual vs logged reading
- •Review consumption trend
- •Confirm ECV accessible
Annually
- •Verify pulse/comms output
- •Confirm correction factors
- •Check ventilation and condition
- •Review trends and sizing

Managing Gas Meter documentation with PM Assist
PM Assist helps FM and building operations teams search their O&M manuals and building drawings in seconds. Upload your gas meter (mains & sub-meter) documentation and ask questions like “Where is the gas emergency control valve?” or “What correction factor applies to this meter?” — and get source-cited answers instantly.
The checklist tells you what to check. The manual tells you the numbers.
Ask a gas meter manual a question and get the answer back with the page it came from. No signup, and you can drop in your own PDF instead of the sample.
“Where is the gas emergency control valve?”Runs against a sample chiller manual so you can see the shape of the answer — then try it on one of yours.
