Check whether the bill is based on an estimated meter reading, and compare the kilowatt-hour usage with your previous bills rather than looking only at the dollar amount. Seasonal heating or cooling, a change in household use, tariff changes or a missed previous adjustment can all affect an electricity bill. Contact your retailer if the reading or charges look incorrect, and ask about payment plans or hardship support if the bill is difficult to manage. You can also compare available offers through the government-backed Energy Made Easy website.
