Dear Customer,

Now, you have the possibility to take your meter readings in order to find out your consumption. 
So, you can register the meter readings by yourself every 4 months, so as to cancel the scheduled procedure of estimation upon consumption through the IT systems of HEDNO S.A..

Easy - Safe - Quickly

How often does HEDNO take meter readings?


For standard Low Voltage customers (residences, shops, small businesses etc), HEDNO S.A. takes meter readings every 4 months.

Specifically, for the first 2-month period, HEDNO S.A. uses the estimated consumption, while in the second 2-month period the meter readings are taken by the Company personnel so as to calculate the total consumption of the 4-month period (it is calculated automatically by our IT system as the difference between the current reading and the reading registered by the Company 4 months ago). 


How the estimated consumption is calculated?
The estimated consumptions are calculated automatically by the customer service IT system. It is based on the specific algorithm that consists of the historical consumption data, such as the consumption of the equivalent period of the previous year. Consequently, the specific consumption does not significantly differ from the actual bimonthly period consumption, unless the customer’s consuming habits are differentiated within the last period of time.

Why should I use the metering registration service of HEDNO S.A.?

If you choose to use the metering registration service , then HEDNO S.A. will cancel automatically the scheduled estimation of your consumption and will calculate instead  your total 2-month consumption period which derives from the difference between the readings that you have registered and the readings registered by our Company two months ago.

If you do not use this service, then, it means that you choose the estimated consumption calculation according to the procedure mentioned above.

It is your choice.

When can you register the readings?
Within the 5-day period which is clearly stated on the first page of your bill above the table of the meter readings (in circle on the following figure).
