How do I read my meter?


Dial meters

Clock-face dial meters have four, five or six dials, which alternate in direction. To read these meters:

  • stand directly in front of the meter
  • starting from the right, read each dial and write down the figures
  • when a dial hand points between two numbers, write down the lower of the two
  • if the hand points between 0 and 1 write down 0, but if the hand points between 0 and 9, write down 9 [previous 2 points need work]

For example, the reading in diagram 1 is 2-7-0-3-8, that is, 27,038 kilowatt hours (units).

Electronic meters

Electronic meters have a six-digit display register.  The register can be static or can automatically step through a sequence of displays depending on your tariff.  A number that appears at the top right-hand end of the register identifies each display or channel. For those meters on a standard residential or commercial tariff (A1, L1, K1 or M1), where the registers stay static, you simply write down the numbers that are displayed.
For those meters on time of use tariffs, the meter register channels are specific to you
For those meters on time of use tariffs, the meter register displays/channels are:

Channel Name / Description
01 Meter Code
02 Meter Serial Number
03 Programme ID Number
04 Time
05 Date
06 Kilowatt hours/Pulse
07 Total Kilowatt hours
08 Present Demand
09 Reset Number
10 On Peak Kilowatt Hours
11 On Peak Indicative Demand
12 On Peak Cumulative Demand
20 Off Peak Kilowatt Hours
21 Off Peak Indicative Demand
22 Off Peak Cumulative Demand
30 Weekdays Shoulder Kilowatt Hours
40 Weekends Shoulder Kilowatt Hours

Not all channels are displayed on all meters. This depends on your tariff.

  • Customers on R1 tariff need to write down the figures from channels 10 and 20
  • Customers on SM1 (Smart Power) tariff need to write down the figures from channels 10, 20, 30 and 40
  • Customers on time-based demand tariffs S1 and T1 need to record channels 10, 12, 20 and 22

Bi-directional meters

Bi-directional meters measure the customer’s energy consumption and their net energy generation. Anyone who has installed a system which generates energy into Western Power’s grid must have a bi-directional meter fitted. This normally happens as part of the process for successful applicants to Synergy’s Reverse Energy Buyback Scheme (REBS), but also applies to customer’s with generation systems who are not part of the scheme.

Smart meters

A smart meter is a more sophisticated electricity meter that records the electricity usage in the home in half hour intervals as well as the total consumption. It is capable of two-way communication and automatically sends this information daily to Western Power.

Smart meters are part of a wider initiative by Western Power called Smart Grid which seeks to take a traditional “poles and wires” electricity grid into the future by adding digital and communication technology. This makes the grid more flexible and adaptable to your needs.
