As all meters are now smart meters, meter readings are being performed automatically by the network operator. Only in isolated cases, when the data transmission system does not properly work or in rare cases where a conventional meter still exists, network operator agents come on site to read the meters.
Your supplier calculates your bill on the basis of data collected automatically or manually by your network operator.
At any time you may ask your network operator or supplier to provide you with your recent consumption data. Some suppliers and network operators provide this information via their Internet portal.
