Before you use the number
Why do billing days matter?
Consumption bands and annual service charges are allocated to the length of the billing period. Choose a standard or leap year and use the actual number of days rather than assuming every bill covers two calendar months.
Do more residents increase the electricity bands?
The electricity consumption bands used here are per household. Registered residents affect eco-reduction eligibility. An optional estimate can apply this only when you assume a qualifying account and actual reading. Water uses a different approach.
Why might my bill be different?
Account adjustments, eco-reductions, government support, credits, arrears, meter readings and the billing provider calculation can change the final amount. Check the tariff printed on your bill.
