If you think your bill is incorrect please check the charges are based on actual (rather than estimated) readings.
For electricity, if your estimated readings are within 250 units of the reading on your bill, your bill does not need amending. For gas, if the difference is within 45 units for a 4/6 dial meter and within 120 units if you have a 5 dial meter, then your bill doesn't need amending.
If your bill is higher than you expected you can also check how many days the bill is for, as it may be for a longer period of time than your normal bill. You can also check to see if your prices have recently changed.
The more factual readings we have on your account, the more accurate any future estimates will be as we'll have a better record of your recent usage. Actual readings include readings provided by you, obtained by our appointed meter readers or collected electronically through the meter.
