Checklist: Checking the electricity meter – this is how you proceed if you suspect something

This step-by-step guide will help you identify a faulty electricity meter:

1. Compare electricity consumption: Compare your current bill with previous year's. An unusually high electricity bill can be an early warning sign.
2. Read the meter reading regularly: Note the electricity meter reading at the same time every day and observe any fluctuations.
   
3. Turn off the main fuse: If the meter remains active even though all fuses are off, it is probably not working correctly.
4. Disconnect devices from the power supply: Unplug all plugs – if the electricity meter continues to run, there is probably a defect.
5. Check calibration period: Check whether your electricity meter is still calibrated – expired deadlines can affect the measurement accuracy.
6. Inform your grid operator: If you have persistent suspicions, you should contact your grid operator or electricity supplier.

If your network operator confirms the meter is defective, they will usually replace it free of charge. You will usually receive a modern digital meter or an intelligent metering system (smart meter). The replacement may only be carried out by a qualified technician and is usually quick, safe and uncomplicated for you.

Can I replace the electricity meter myself?
No, the replacement may only be carried out by qualified personnel – usually commissioned by the network operator.

How often do electricity meter defects occur?
Relatively rare—especially with newer, digital models. Older Ferraris counters are more susceptible, especially after the calibration period has expired.

How long is my electricity meter calibrated?
Electronic meters: usually 8 years
Ferraris counter: up to 16 years

What happens when the calibration period has expired?
An electricity meter without a valid calibration may no longer be used for billing purposes. The grid operator will usually replace it automatically. If this doesn't happen, you should actively contact them.

Conclusion: Proceed in a structured manner if suspicion arises

A faulty electricity meter can be frustrating – but with a cool head and the right approach, the problem can be quickly resolved. Use the checklist, read your meter regularly, and contact your grid operator if you have any questions. This way, you can ensure you only pay for the electricity you actually use.
