Identify the meter and display
Before recording a number, check whether you are looking at the electricity or gas meter and whether the display has more than one register. Keep the meter serial number or a clear photograph if the account has more than one meter.
Record the correct digits and unit
Follow the instructions for the meter type and record the digits the supplier expects. Do not include decimal places or red digits if the meter instructions say they are not part of the reading. A smart meter, digital meter and traditional meter may present information differently.
Keep the date and reading together
Write down when the reading was taken and whether it was supplied to the supplier. This helps distinguish a current customer reading from an earlier estimate and makes a later bill easier to reconcile.
Check two-rate and gas conversions carefully
For a two-rate electricity meter, record both registers and the labels shown on the bill. Gas bills usually convert meter volume into kWh, so compare the billed kWh and conversion details rather than treating a meter-unit number as a kWh figure.
Ask for an explanation when the bill still differs
If the reading, dates or register labels do not match the statement, send the supplier the dated reading and ask which readings and conversion were used. Keep the confirmation and the bill together.
Common questions
Should I record a meter reading even if the bill is estimated?
A dated reading can help the supplier compare the estimate with the meter, but follow the supplier’s submission process and keep the confirmation.
Why does my gas meter number differ from the bill kWh?
Gas bills commonly convert meter volume into kWh using bill-specific conversion information. Compare the bill’s units and calculation rather than copying one number across.
