How to read your meter
Reading your electricity meter can help you manage your energy usage and avoid estimated bills.
Reading a revolving disc meter
This is the most common meter type for domestic buildings. It has a revolving disc and one or two rows of numbers.
To read your revolving dial meter:
- Note the number from left to right.
- Ignore any figures in red or any figures surrounded by a red box.

Standard meter
Records your electricity usage on a single register.
If you are on an Urban 24 Hour or Rural 24 Hour price plan, you will probably have this kind of meter.
If you have night storage heaters, you will have two of these meters.

Day and night meter
Records your day and night time electricity usage.
These meters may have numbers 1 and 2 or the roman numerals I and II beside each register.
On all ESB meters, I refers to Night and II refers to Day.
If you are on an Urban Nightsaver or Rural Nightsaver price plan, it is likely you will have this type of meter.
Reading an electronic meter
Electronic meters are now being installed in some homes. They have scrolling electronic displays which show a number of different meter readings.
- Take your reading from the appropriate screen depending on your price plan.
- Note numbers from left to right.
- Ignore any figures to the right of the decimal place.

Electronic meter
The display automatically changes every 9 seconds to show you 20 different types of meter readings.
Screen 9: Normal or Day time reading (Urban 24 Hour and Rural 24 Hour price plan customers)
Screen 10: Night time reading (Urban Nightsaver and Rural Nightsaver price plan customers)
