How to read your gas or electric meter


This guide makes it easy to find out how to read your gas or electric meter. By reading your meter and giving us your reading, you’ll always know how much energy you’re using.

And if you give us your meter reading through your online account, you’ll get an up-to-date balance straight away. If you don’t have an online account, you can register for one using the link at the bottom of the page.

Reading your electric meter

Our page on different meter types will help you find out which electric meter you have. You'll find the link at the bottom of the page.

Meters with one reading (single rate)

Digital meters

These meters have a number counter that records your usage.

  • Read the first five numbers from left to right.
  • Include any zeros, but ignore any numbers in red or after the decimal point or space.

Dial meters

Some older meters have dials instead of numbers. To make things easier, write the numbers down as you go.

  • Read all the dials from left to right, but ignore the dial marked 1/10.
  • If the pointer on a dial is between two numbers, write down the lower number. If it's between zero and nine, it will be nine.
  • If the pointer is exactly on a number but the following dial reads nine, you need to take one away from the number.

Meters with two readings (two rate)

Digital meters

A meter with two readings (two-rate) divides what you use between day (normal/peak) and night (low/off-peak).

They have two number counters to record your usage. Next to each counter you'll see Normal and Low or N and L.

  • Read each row of numbers from left to right, including any zeros at the beginning. 
  • Ignore any numbers in red or after the decimal point or space. 
  • Make a note of which read is normal and which is low.

Electronic meters 

Some two-rate meters have an electronic screen. You’ll need to press a button to view your readings.

  • Press the button and note down everything that comes up on the screen as you do so. 
  • A letter, number or word will show which rate the reading is for. For example R1 and R2, 1 and 2 or L and N.
  • Not all meters are the same so R1 could be for day or night. The easiest way to check is by looking at your previous bill and seeing where your readings fall in line.
  • You could also take two sets of readings about an hour apart, within the times for one of the rates. The reading that moves will be for the current rate.

If you have more than one electric meter

You may have more than one electric meter. Take the readings as explained above and make a note of the meter serial number along with them. If you need any help, contact us using the link at the bottom of the page.

Reading your gas meter

Digital gas meters

Gas meters are either imperial or metric. Imperial meters should have four main numbers; metric meters should have five.

Imperial meters

  • Read the first four numbers from left to right. 
  • Include any 0s at the beginning, but ignore any red numbers or numbers after the decimal point or space. 
  • When the meter reaches 9999 it will start recording from 0 again.

Metric meters

  • Read the first five numbers from left to right. 
  • Include any 0s at the beginning, but ignore any red numbers or numbers after the decimal point or space. 
  • When the meter reaches 99999 it will start recording from 0 again.

Dial gas meters

  • Read all the dials from left to right but do not read the large dial or any red dials. 
  • If the pointer is between two numbers, write down the lower number. 
  • If the pointer is between 0 and 9, use 9. If the pointer is exactly on a number, write it down and underline it. 
  • If any of the numbers you have written down are followed by a 9, take one away from the underlined number.
