Key answer
What the comparison includes
Each estimate includes annual kWh multiplied by the unit rate, 365 days of standing charges and any known annual fees entered. Taxes and variable or omitted charges are excluded, so check the written terms before deciding.
Before choosing the lower result
Confirm that both offers relate to the same meter, start date, contract duration and payment basis. Review commission, capacity, metering and pass-through items. A cheaper estimate can still carry greater variable-cost exposure.
Save the original quotes and record the assumptions used. This makes it easier to approve the decision and check the first invoice.
