How do I read my meters?

Meters with rotating counters (mechanical meters)

Write down the numbers shown on the display, reading from left to right. Don’t include the red numbers, any numbers with a red border or numbers after the decimal point.
How to read mechanical meters.

Meters with a digital display screen (digital meters)
To read this type of meter you need to press the button on the front of your meter, the colour of this button can vary depending on the type of meter you have.
Each time you press the button a different display will show, note down everything that is displayed. Meter readings will be displayed next to a letter or number to show which rate the reading is for, these are normally, R1 or R2, 1 or 2, L or N, Low or Normal.
Some meters with digital displays will change between the readings automatically every few seconds.

Meters with clock-style dials (dial meters)
Read the dials from left to right, starting with the dial labelled 10,000.
If the pointer is in between two numbers, always use the lower number, except when the pointer is between nine and zero – in this case, use the number nine.
Each dial will turn in the opposite direction, so if your first dial turns clockwise, the second dial will turn anticlockwise. Be sure to remember this when recording your reading.

Smart meters (digital display)
If you have an electricity single rate smart meter, the display will automatically show the reading.
If you have an electricity dual rate smart meter, press and release the blue display button and this will show rate two.
For gas smart meters, press and hold the red button A for 5-10 seconds, this will then display ‘Credit ON’. Press and release button A, and the meter will display the reading.


I think my meter is faulty, what should I do?

If you think your meter is faulty because your bill is higher than you expected, consider these points first:

  • If the meter readings we used were read by yourself or a meter reader, they are not estimated
  • If we’ve under-estimated your bills in the past, your bill will be higher as we’re charging you for energy used in previous months
  • If it’s winter, you may be using more energy during these months
  • If there’s been a price change since your last bill
  • If you’ve changed anything in your home, for example you’ve installed or introduced new appliances
  • If there’s been an increase in the number of people in your home
  • If you’ve been doing home improvements, the tools and appliances used for the work may increase your energy use
  • If you have more than one reading on your meter they could be mixed up

Once you considered these points, you can take one of the following actions:

  • If your bill is estimated, please read your meter and send us your reading.
  • If you manage your account online, you can log in and give us your meter readings. Once you’ve entered your readings, you’ll have the option to create your bill.

You can get in touch with us for help with a faulty meter. Email us or call 0345 052 0000. Lines are open 8am to 8pm Monday to Friday, and 8am to 6pm on Saturdays.

I've just had my meter changed, do I need to do anything?

No, you don’t need to do anything – we’ll update your account automatically. This may take up to six weeks, but don't worry – we'll back date any changes.


My new meter details aren't showing on my bill, what should I do?

If your meter has been changed in the last six weeks it’s possible we haven’t updated your account yet. The next bill we send you should show the correct meter reading. If this isn’t the case, or you have any other concern, please contact us.

What is Economy 7?

Economy 7 (E7) is an electricity tariff that has different unit prices based on the time of day.

The E7 tariff offers seven hours of cheap rate units during the night. Daytime units are charged at a higher rate than E.ON EnergyPlan, our standard tariff.

To benefit from an E7 tariff you need to use more than 34% of your electricity during your night-time cheap rate hours.

If you use less than 34% of your electricity during your cheap rate hours, you’d probably be better off on our single rate tariff.

You can get a quote using our online quote tool, but don't tick the E7 box.

Note the 34% figure is based on our E.ON EnergyPlan prices, and Ofgem’s average for E7 consumption, which is 4,600kWh.

Times for the cheap rate period can vary from household to household, as they depend on the type of meter and teleswitch you have fitted, and the area where you live.

If you already have an E7 meter and you’re not sure of your cheap rate times, call us on 0345 052 0000 (8am to 8pm from Monday to Friday or 8am to 6pm on Saturdays).

If you don’t have an E7 meter and you’d like to change to an E7 tariff, you need a new meter. If you're already with us, call 0345 301 5793 (8am to 8pm from Monday to Friday or 8am to 4pm on Saturdays)
If you're not with us and you’d like to switch to E7, you need to contact your current supplier.

How do I know if I have a metric or an imperial gas meter?

You’ll be able to tell which type of meter you have by checking the number of digits that make up your meter reading:

  • Imperial meters have four-digit readings, not counting any numbers in red or after the decimal point – these meters measure in cubic feet , also shown as ‘hcf’.
  • Metric meters have five or six-digit readings, not including any numbers in red or after the decimal point – these meters measure in cubic metres, also shown as ‘m3’.

I can’t open my meter box, what should I do?

You open outside meter boxes with a special key. To take your meter readings, you may need a key.

If you’ve just moved into your house, the previous occupier may have left a key for you.

If you need a meter box key, please contact us.
