Calibration intervals

Scheduled meter change

Meters are replaced at regular intervals because their calibration periods expire at set intervals.

Obligation to replace

The obligation to replace meters and the calibration intervals are statutory requirements set out in the Measurement and Calibration Act (MessEG) and the Measurement and Calibration Ordinance (MessEV), which is why we are also obliged to replace the relevant meters.

Calibration intervals

What are the calibration intervals for the most commonly installed standard meters?

Electricity: Electronic meters – 8 years; Ferraris meters – 12–16 years

Gas: Generally 8 years

Cold water: 6 years

Hot water: 6 years, since the amendment to the MessEV in 2021

Heating: 6 years

For all categories, an extension may be granted, subject to a random draw where necessary.

  • Meters have a specific calibration validity period, which may vary depending on the type of meter and sector. These calibration validity periods can be extended on a batch-by-batch basis through random sampling procedures.
  • The samples are selected by a randomisation process and must be tested within a fixed two-week period in accordance with strict legal requirements; for this reason, we may contact you at short notice by telephone to arrange an appointment during the testing phases.
  • If you have any doubts as to the authenticity of our call, you can contact our customer service team during our opening hours.

How does a rotation work?

Scheduling

If a meter’s calibration period expires in the relevant year, we or our service provider will contact you during the course of the year to suggest a date for the meter replacement. If this date is not convenient, please let us know by emailing dispo@swk-kl.de.

Meter replacement

On the agreed date, our technician will come to the relevant meter reading point, show their ID and replace the meter.

Payment

This service is free of charge. Please note that the meter must be freely accessible at the time of the appointment.

Our service provider

We are supported by our service provider, Enwas, in replacing meters. Enwas replaces the meters and sends appointment letters to customers.
