Your bill fluctuates throughout the year depending on your energy use and the season. Some simple explanations for a higher electricity bill include:
•Cold weather - In cold weather, most homes use more energy. Your hot water system has to work harder to heat the water, longer showers are common and you're likely to use room heaters more.
• Hot weather - In the hot weather, some households use air conditioners to cool their homes. Every degree of extra cooling however may increase your energy consumption by approximately 5-10%. Think about the potential for savings when you set your air-conditioner at a temperature that keeps you comfortable but doesn't use unnecessary electricity. Set your air-conditioner to an energy-efficient 24°C in summer and 18°C in winter. Seal gaps and close doors, windows and curtains to cool or heat rooms quicker and keep them at a comfortable temperature for longer.
• Changes in your household - Have additional people moved into your home? Are you spending more time at home? Do you have any new electricity appliances?
•Your account was estimated - If your meter hasn’t been read, we've had to estimate your energy use.
• There was a mistake in reading your meter - Check your current meter reading against the reading on your account.
• Your billing period may be longer than your last account - Compare this bill with one from the same period last year. Your appliances (such as your appliance on stand–by power) may have been operating while you were on holidays. If this is the case, simply switch your appliances to the vacation setting next time you go away.
