Our online billing service on your online account has a handy bill calculator feature which you can use to estimate how much electricity you’ve used to date. If you have not activated your online account you can register here.
If you receive bills by post, you can calculate your electricity costs by:
Taking your current meter reading and subtracting the previous meter reading (find this on your last bill) to find out how many units you have used.
Next multiply the units used by the current unit rate for your tariff (find your unit rate).
Add VAT at 5%.
