What the law actually says

Two key obligations affecting every apartment building and owners' association in the Czech Republic.

📌 Existing meters, deadline 31. 12. 2026

All older meters without remote reading must be replaced at the latest during the next replacement due to calibration, but no later than the end of 2026.

Case study

Apartment building in central Prague: 15 flats, 44 meters

The owners' association in the historic centre of Prague addressed the replacement of meters as their calibration was nearing expiry. The previous system required physical readings, annual scheduling of appointments with all tenants.

After installing remote meter reading, the building manager can view the entire building's consumption in real time. Within the first month, the system detected a water leak in one apartment that the owner was unaware of, with estimated savings on repairs amounting to tens of thousands of Kč.

Frequent questions

Answers to the questions most frequently asked by building managers and owners' association committees.

Do we really have to replace the water meters by the end of 2026?

Act No. 362/2021 Coll. Mandates remote reading for all meters. Replacement must be completed no later than the next expiry of calibration, but at the latest by 31. 12. 2026. Under the new Decree No. 127/2024 Coll., the calibration validity period is 5 years for mechanical water meters.

What will be the total cost of the replacement?

It depends on the number of flats and meters. As a guide: a residential building with 15 flats and 44 meters comes to approximately 177 000 Kč excluding VAT for installation + 1 500 Kč per month for system management. We will prepare an exact quote following a free consultation.

Who pays for water meter replacement: the building's owners' association or the flat owners?

Apartment water meters (ratio measuring devices) are the property of the building's owners' association or the apartment building. The costs of replacement are paid by the building's owners' association, typically from the repair fund. The decision is approved by the owners' assembly.

How does installation proceed: must the tenant be present?

Yes, someone must be present during the water meter replacement in an apartment. Installing one apartment takes approximately 20-30 minutes. We can complete the installation for the entire residential building within 1-2 days and will coordinate the scheduling.

How does the application for owners work?

Each flat owner receives access to the web or mobile application, where they can view their current water meter reading, consumption history and any alerts. The manager sees the entire building. Data is available 24/7.

What happens after 5 years when calibration expires?

We will arrange recertification or replacement at a discounted price of 2 000 Kč / unit for existing customers (includes removal, calibration or replacement and reinstallation). The system will automatically notify you in advance.

Does the system also work for heat meters?

Yes, we also supply and install heat meters (calorimeters) with the same remote reading capability. The price is the same as for water meters, 3 800 Kč per unit, including calibration and installation.

Where do you operate? Do you also serve areas outside of Prague?

We primarily serve Prague and the Central Bohemian Region. For larger orders (20+ meters), we can also operate elsewhere in the Czech Republic; transport costs will be specified individually in the quotation.
