It could be that your previous bills have been based on estimated reads and this one is based on an actual meter read. Look at the back of your bills under the ‘Usage Details’ section. If meter readings are estimated, they'll be clearly marked with (E). If your account has been estimated for a period of time, an actual meter read may mean a larger or smaller than expected bill. This is because your account may have been under or overestimated for a period of time and this bill is correcting that.
If so, read and submit an actual meter read. We will cancel (reverse) this bill and re-bill you using these actual reads.
Your current bill may cover a longer or shorter period than your previous bills. If so, you should check if the daily charge in this bill is in line with previous bills. This is calculated by dividing the total value of the bill by the number of days the billing period covers.
Your energy consumption can increase for lots of reasons, for example, fitting new appliances or machinery, extending your premises or changing your business hours.
The time of year can also impact the amount of electricity you use.
