Users can order an inspection of the metering device's precision, carried out using a reference tool at the cost of EUR 85.96 (VAT included). If the metering device is not accurate within the statutory limits, those costs plus the costs of replacing the device are covered by the distribution network operator, Elektro Ljubljana, d. d.

If a user requests that the inspection be performed by an accredited legal entity, there are additional costs for such entity's service on location.

In this way, the metering device is tested in the measuring laboratory, which consists of measuring the precision of the counter and drafting a report, and adds up to an additional EUR 164.43 (VAT included).
